I am trying to decide between these oils in 5W30. Have been using Mobil 1 full synthetic but thinking about switching. My car is loosing about a quart of oil between oil changes not sure why. It started last spring or winter I think. Though, I doubt it has anything to do with the type of oil Im using. I was using racetrack gas regular octane when the gas prices were so high. Since I realized I was having issues I have gone back to higher octane and other brands such as Shell and Chevron. My car has 116K miles and the only engine mods are injen intake and some kind of german plug wires (think were for the SR engine) but was told I could use them. I replace the oil about every 5K miles. Also looking at getting the mobil 1, K&N gold or Amsoil oil filter. Anyone have any bad experiences with these.

First and foremost, find the cause of your leak. It will save you a lot of troubles in the future.

Most Mobil 1 synthetic oils on the shelves are decent, but they aren't specifically designed for racing. They have a specific formula for racing use. If you aren't a full blown race car (which it doesnt sound like you are) then you should be fine with any of the oils you were asking about.

On a side note, Amsoil is technically the FIRST company to produce and use synthetic oils for normal automotive use, so they have the most experience. Does that make it better? It depends on who you ask...lol.

I personally like Redline oil.

Old valve stem seals = burning oil, try 10w-30 it's a little thicker and doesn't burn off as quickly
I used to use royal purple oil, but recently switched to Mobil 1... no complaints here

mobil 1 is ok because its everywhere. it does go thin real quick compared to others.

royal purple is ok but i hate the color cause i can't tell when its dirty. but feels ok. lasts better than mobil 1.

Redline is best shit i ever tried. car feels so smooth and it lasts a while, does not go out as quick as mobil 1. REDLINE IS BAR BEST imho

12-23-2008, 09:51 PM

ive used MOTUL, Royal Purple and Mobile 1.

i went from that order as well.

i found Motul to be great and enver had oil leaks and after 5k km's it was still gold.

Royal Purple well it was good didnt have any complaints with it but didnt like how its a dark oil so hard to tell if its old or new oil.

Mobil 1 well i used it cause it was cheap. i liked it and stays gold til a lil over 4k km's. but engine is leaking now. unsure if its oil related or just over time a leak has started.

I use mobil one synthetic, works good for me. I also have an oil leak, every morning i get a little puddle under my car i think its my rear main. Just add oil when you're a little low. I check my dipstick every morning cause i dont have time to change that damn main seal yet.

emersonLP

12-23-2008, 10:32 PM

Theres a group of guys on my350z forum that tested a bunch of oils and compile the results continuously to see how they break down and what kind of deposits are in the oil and what-not. I don't know all the results, but having been over them, I stopped using royal purple and switched to European blend Castrol 0w30 or Mobil 1 0w40 because they performed better in the tests and they are a couple of the few true synthetic oils that are readily available and reasonably priced.

12-23-2008, 10:38 PM

I had the oil pan seal replaced back in June for the 3rd time but I still lost the same amt of oil afterwards. I just had it in and they said the oil pressure switch was leaking which is the 2nd time for that but that was the only leak. I haven't been noticing any oil under the car even before they did the oil pan seal. I have had leaks before like since I've practically had the car but the dipstick has never changed readings..its always been at the H line so its just been in the last year. I assume I'm burning oil but there is no smoke coming out of the exhaust pipe and the mechanic says it runs fine and not sure why Im loosing that much oil either. Gas mileage seems normal..getting about 22 in city. I just had the knock sensor replaced since it was causing a check engine light and 2 EGR valves replaced last spring. I also had a spark plug wire blow out of the engine last spring as well before the EGR valves went. They told me that wouldn't cause any damage but I first noticed I was loosing oil sometime after that.

I heard there were dyno test done and it showed that Royal Purple gave about a 8-9 HP increase just from using the oil. NE1 heard of such a thing???

12-23-2008, 10:46 PM

oil doesn't add hp. I couldn't even tell the difference between conventional and Mobil 1 full synthetic.

I just changed with Valvoline Full Synthetic
I read somewhere it stays cleaner longer than Mobil 1

Obviously oil doesnt add HPs but the car can run more efficiently or less efficiently depending on what fluids used.

Bigsyke

12-24-2008, 01:10 AM

Royal purple will NEVER touch my engine, ever.
Mobil1 will Probably never touch my engine again, its in no way shape a synthetic, except for the detergents
Amsoil is now the only thing I use.

Either way you could use dino, makes no difference, however;

Im a believer that a true synthetic would withstand fuel vapors far better than Dino, and I also go off of BITOG reports that amsoil is for me.

Mobil1 tends to break down quicker, thus might as well use a dino oil, both are nearly identical.
Royal purple is nothing else but a fancy dino oil, and a tranny shredder.

Amsoil for me, and an OEM filter. And Im starting to think WIX filters are the devil in cold weather.

+1 for this guy... that's the oil they were surprised held up better than motul and royal purp, redline, and mobil 1 aaaaand amsoil.

And it's cheaper

dubmasterdee

12-24-2008, 12:27 PM

not so good to change brands of engine oil often... should not compromise viscosity because of leak...

i just use mobil 1 10w-30.. works fine... pick it up from the local walmart/autozone and you are good to go

my buddy always say: "you can't beat an oil leak from a FC... it is the king of oil leaks"

Good luck

I use castrol 5W-30 with OEM filter, never had any probs, and i too was losing 1 quart every oil change, but mine was the rear main seal. This must be a common problem on KA nissans. You may want to consider using i quart of lucus oil treament with 3 quarts of regular oil, this tends to help engine run quieter and a little better, just a suggestion.

Well I personally dont care to browse BITOG, HT and other forums for hours.

Why would you use a racing oil for your DD if all you need is regular dino? There is no added protection in Royal Purple than in Amsoil or Mobil1.

You could use A standard 5w30 dino oil, and would make no difference as long as changed regularly.

blueshark123

For engine oil use Enos j/k to expensive for nothing i use castrol full synthetic and for the tranny i use gm synchromesh. I used royal purple for the tranny before but it sucks

i just know one thing.

mobil 1 breaks down quick.

i had it my s14, sr with pretty decent size oil cooler. you could tell the oil is breaking down after about 1 month of driving, 2 events or so. what the hell. on the other hand redline stays clean longer and takes twice as long to break down

smelly240

12-24-2008, 04:46 PM

Castrol still using organics in it's synthetic base stock?

not in the German Syntec :D

bobistheoilguy.com - there is truth in that royal purple while a full Tier 4 - is mediocre at best when it comes to protection.

It has poor shear qualities when compared to amsoil, German Castrol, and Mobil1

The Amsoil is expensive - but great

The GC is at your autozone but only comes 0w30 (but when measured is thicker than MANY 40 weights.)

Mobil one - everywhere, and a quality oil.

I use the 0w30 and have no problems. The Pennzoil plat is good oil as well.

McRussellPants

12-24-2008, 05:00 PM

Best Combination I've used is

Torco SR5 + Amsoil Filter

Comes out after like 5 events still clear.

Torco, Amsoil and Mobil I've been really happy with.

Power Neo I was really disappointed with though.

Bigsyke

12-24-2008, 06:52 PM

The only way to tell if the oil is doing its job is sending a sample to blackstone lab, amsoil seems to be the top of the list even if its a MLM company.

There was a recall on an amsoil filter however, thats why I only use OEM

12-25-2008, 11:53 AM

Thanks for all the replies! But there doesn't seem to be any consensus so I guess its just a crap shoot. Not sure. I looked at Amsoil but they seem to spend most of their adverstising just ridiculing Mobil and other co's. They have 2 different synthetics, XL and one thats more expensive. Their oil filter looks good but its terribly expensive. Im using K&N filter right now so may just stay with it or Mobil filter but not sure about the oil.

12-25-2008, 12:06 PM

Do you not realize that after 6 oil changes with that synthetic shit, you could just buy a new motor with the same money? Its just a stock ka for fucks sake.

Castrol GTX or go broke.

Spend more money on oil when you have a bigger investment to protect.

Pacman

12-25-2008, 05:59 PM

Why are you using the 40 and not 30?
Why is he using an engine oil intended for a diesel?

I use Valvoline Syntech. Why did I switch from Mobil One to Valvoline? I get it free at work (don't tell the boss...). The ONLY filter I use is Nissan Genuine oil filter. It's a $6-10 oil change, depending if I wear my Toyota uniform when I go or not. I've heard horror stories about FRAM and other filters. I change my oil every 3,750 (as per FSM and owners manual) and have a leak at my oil pan (which I will fix when I get my P/S rack and return lines). Any difference in the performance? Not that I noticed. I noticed a difference in gas mileage but that could be cause the cold weather.

Remember, change your drain plug gasket at every oil change. I've seen those leak bad when its torn up/missing.

12-27-2008, 01:45 AM

Royal Purple is the shit. Best oil, blows mobile1 out of the water. Ive seen a test using three different oils, cheapest Chevron oil, Mobile1, and Royal Purple. They performed the test using chevron oil(brand new just opened container), messed the bearing up. Second with student provided Mobile1, messed the bearing up but not nearly as bad as the shitty oil. Third with royal purple, bearing came out with just a very small scratch. Then they did the same test with the shitty oils and just added a couple drops of Royal purple into the Chevron oil, made it perform like mobile1, and same with the mobile1, mobile1 performed much better.

I am sold on royal purple. To each his own.

Just add one quart to every oil change if you cant afford to run it. Based on the test it should make a big difference. The oil last a lot longer too so you dont have to do as many oil changes per year.

Bigsyke

12-27-2008, 01:30 PM

^^^^yea but that oil breaks down faster than any oil out there.

Id run it maybe 1,000 miles tops.

Whats the fucking magic juice composure thats going to make a car last FOREVER!???

How is it so good?

If it doesnt last longer than a dino, whats the advantage durring that short 1,000 mile interval

Define "breaks down" please

Its racing oil, non synthetic.

Mobil1, non synthetic base stock, with synthetic addatives.

Royal purple's tranny fluid is also the worst oil availible for most manual transmissions.

I personally like Redline oil.

LOL,I don't know about now but it used to be Redline was not even API certified hahahhahhahha.
Where as Amsoil is not only API certified but exceeds rating standards. Not saying Redline is shitty, but I have used Amsoil for years with extended drain intervals.
It's actually one of the few oils out there that's actually rated for extended drain intervals( upwards of 12k-25k depending on the filters you use)

Oh and do not run Redline MTL in your trans unless you want it to sound like its going to blow up. LOL

In the end Amsoil is based on pure synthetic base stock and made to exacting standards. Its excellent Synthetic oil and worth every penny.
I would add Motul is great too. My Motorcycle buddies have always sweared by Motul.

I would take either of these before I ran any other Synthetic on the Market.

Oh and for the breaks down question? Basically that describes a oil losing its Viscosity, once a oil loses its Viscosity i.e. breaks down, Its loses its lubrication qualities which means excessive wear and tear on moving parts. LOL

actually RP doesnt break down faster, one of their biggest selling points is that you dont have to change your oil as often. Dont matter which oil is in my car, if its getting driven its getting changes every 3k at the most anyways. RP is magic juice.

You are wrong sir, of course a company is going to advertise that. Its already been debunked;

Fine if you like paper end caps that esplode. I stopped using them when they started using PTFE in the filters(10+ yrs ago). I wouldn't use fram if it's the only thing the store had in stock.

I've used CastrolGTX in all the daliys. My current engine is worth the extra insurance of Synthetic. I wouldn't be proud to be a CB.

Although I have no complaints whatsoever, after reading this thread perhaps I'll try out a different oil for my next oil change, still love the K&N filter though.
For the transmission, I use the same oil that I run in the motor, haha.

Use Redline in your tranny, then go back to what you used to use and I will personally paypal the funds the oil of your choice.

Ha ha.

redline is awesome for tranny. used mt90 in sr tranny for years, shifts like butter. need to get some atf for the t56 now

Im using lucas full synthetic now in my open diff. However that may not be the best.

Just make sure you change it out often, my Diff's plug was filled with shavings

I think Im going to go ahead and try something different than Mobil 1 full synthetic that I have been using for several years now since I've had leaks. Im doubt it will help but figured I'd try something different. So I've narrowed it down to RP and Amsoil. Is there a preference when it comes to preventing leaks? Oh, and I saw that Autozone had a deal on 5qts of Castrol Syntec 5w30 + Mobil 1 oil filter for about $35.00.

go with amsoil. RP and amsoil are the same price, but amsoil is a synthetic, RP is dino, and amsoil WILL last longer, it has also been proven OVER and OVER again by blackstone labs.

I use NEO synthetic for the engine, tranny, and diff. If its good enough for SPL to use, then its good enough for me. pretty cheap too... Also i've compared OEM filters and WIX filters, i prefer the wix because the holes in the mating surface are larger, thus allowing more oil flow, so maybe faster oil circulation, and better cooling and lubrication. However the filtering properties i'm not sure on... and my thinking might not be correct with the 'holes' theory.

Anyone ever heard of Ester oil? its the new thing that came out for the infiniti G37. Supposedly better than synthetic? i dunno my parts manager was making a big deal about it but he might just be a dumbass.

He's talking about non-POA base oils. Nothing new, POE has been used in AC systems since 134a came out.

When you heard us talking about Organic Base vs Synthetic Base stock. We were talking about POA vs non-POA. The US is the only place where you can Hydrocrack POA's and add POE's to it and legally call it synthetic. Everywhere else the base stock has to come from a non-POA source.

For 4 qts, Amsoil would cost about $48. You have to get Amsoil online which you pay for shipping. Also, their website says you have to add sales and excise tax for TX. RP would be about $39 at Autozone. Walmart doesn't carry RP but has Mobil 1 Ext perf I think for about $30 for 4qts.

Napa, redrooster, oriellys should be carrying amsoil - dunno about the dirty south

Id rather take the mobil1 over the RP. The extra 10$ saved would buy 1 purolator pure one filter, and a Magnetic Drain Plug from Peak.

Honestly, after years of researching the best combo ive came across is

Mobil1 5w30
Wix Filter
1 Treatment of AutoRX

Then there on after

Amsoil 5w30
Purolator pure one filter
Peak Magnetic DP

Yes, Wix, Purolator, and napa gold oil filters are all very good filters. Also, most products that are made by Champion Laboratories are very good.

lets see. for my S13 with SR i use rotella T full synthetic 5w-40, redline MT90 on the trans, motul Pa90 on the kaaz LSD. the combination works fine and the LSD is quiet and smooth intially. the car doesn't see much driving however.

for my DD '05 G35C i tried (as per my350z) to use german castrol 0w-30, redline MT90, royal purple gearmax 75w-90 on the oem VLSD. that's when i immediately experienced a 2mpg decrease in gas mileage. the transmission shifts were difficult in the cold <40deg especially when it sat overnight and the rear diff was howling when temps dropped to the low 30s and below.

i switched back to my usual pennzoil plat 5w-30, ordered nissan oem MTF (oem requires unusual viscosity 75w-85), castrol hypoyC 80w-90 for the oem VLSD and got back to within 0.2tenths mpg of my original gas mileage back. i think oem nissan differential fill is pennzoil 80w-90 which is hard to find locally and in small containers.

some engines and transmissions are very sensitive to the viscosities of the oils. if your current combination works, don't try to experiment and mess things up. my $0.02.

Those filters were made in the US. The filters that were made in Japan are good.

Looks it up here. Someone posted info about the OE filters.

Actually if you look at the pictures, 1 was made in CHINA and the other one was made in JAPAN which looked EXACTLY the same, same case, same color same everything.

This sucks I just bought amsoil online for a total of $48 then the other night I saw Royal purple for 6.87 a qt at walmart. I had gone to the other one a week before and they didn't carry it but this one did. Thats about $20 more expensive!

Bigsyke

01-11-2009, 03:26 PM

So you paid about $10 a qt? funny I just paid $6.99;

and that would be a $14 difference not a $20

I decided to open up my old Bosche Filter.. It's been through roughly 5-6k miles ( I cleaned the oil from it )

close-up OEM filter on right, from the link above

judging from the pictures of the Purolator.. I'd say it was comparable quality for a cheaper price.. $9.59 vs $6.59

I think I'll try that Mobile 1 extended filter next, so I can cut that open.. I'm really not seeing it being that special.

Yes, in Canada you can probably use that all year. Doubt it gets hot enough for 10w-30.

I use Amsoil in everything and it is definately the best in my experience. And yes I have tried RP, redline, Mobile one and just about anything else! I also am a dealer and get you a lot better prices than you have been getting!! Just send me a PM of your needs and I can give you a price quote!!

I use the Dominator race series 10w30 motor oil, the MTG 75w90 trans fluid, and the SG 75w90 for my S14 w/ S15 swap!

Find a dealer local. It's a MLM so a friend of a friend that deals in it will benefit from you buying from them.

The margins on the product is not that great so the big saver will be in shipping. The prices you see on the web are usually full retail, then you have to pay shipping on top of that. Even if you don't get a cut on the price, The weight of the oil can save you some money on shipping buying local.

I switched from Mobil 1 to Amsoil a while back. I wish now that I had done an oil analysis on the Mobil 1, because I recently sent in an analysis sample to Blackstone of my current fill of Amsoil. I have a ROM tune, which probably runs a little on the rich side. If I get a report back saying that I have fuel contamination at 3K, I might as well go back to Mobil 1 and save money since the oil will have to be changed anyway. Other than some fuel contamination that might hinder a 5K mile oil change interval, I dont think that Mobil 1 synthetic would break down signifigantly at 3K or 3750. On the other side of the coin, if all is good on the Amsoil at 3K, and I can go to 5K when Amsoil claims a 15K interval for severe service, than I would still be saving money using Amsoil doing 5K changes.

Amsoil Amsoil Amsoil.

Diff, tranny, engine, transfer case, everything.

They're filters are THE best as well.

As for local parts store shit, German Castrol, Royal Purple, Pennzoil Platinum, Mobil1 in that order.

As for filters, KN/Mobil1 (same thing) Bosch, Wix, Purolator Pure1, Napa Gold are all excellent filters. Anything less, I refuse to touch, recommend, or put on a vehicle. I'll throw that shit in the garbage.

Also, if you're still doing the 3k miles/3 month oil change interval (even on parts store synthetics and quality filter) you're wasting your money. Any combination of the above oil and filter is definitely good to last at least 5k.
Unless you're super hard on your car, doin' track days or events all the time.
