i used to run Royal Purple 10w-30, but i switched to Mobil1 15w-50 and never looked back. Mobil1 is a great oil to run in your SR

AMSOIL.. Good luck finding a reseller close by, or you can order it online.

I run mobil 1 in all of my cars and would not run anything else. Great oil and no problems ever

Royal Purple > Mobile 1 for sure..... Pressure bearing test.... and more HP.

Eneos = Royal Purple

Amsoil > Eneos and Royal Purple....

Royal Purple FTW = available at any Kragen including 0-30 (Behind the counter).

Eneos and Amsoil good luck finding it.

I assume you guys wouldn't run a 20-50 because there is barely any startup protection on that because its way thick and you get no circulation in the morning. THere is a oil weight thread that I posted in tech section. 0-40 for track

I use lucas, royal purple, amsoil, and eneos. All great oils no complaints.. What he said, I think 20winter is way to high even for summer.. 5-40 here in my motors.. Always use oem nissan filters plus they come in blue come on you all love blue..

pwr-adr

and additives I have seen personally save an engine from destruction, knocking that is. I used TX-7 in all my oils.. Great stuff and way over looked in the automotive community.

WISH ONE

I guess I am just a bit biased, the day that I switched over from royal purple to mobile one, I spun a bearing later the same night... theres a great Article floating around here somewhere, Royal purple clearly got some of the better results over MObil one.

No thicker than 10w40 on stock bearing clearances

20w50 is a huge NO NO-

I would run 10w30 at all times in inclimate climate like california, and 10w40 summer, 5w-30 winter in other areas. Nissan / Nismo oem oil for the SR/KA is a full organic and you can buy it online and at the deals. I usually use a good synthetic blend with about half a cup of lucas stabilizer. I don't see any need to run over-priced racing specialty oils if you have the proper engine temperature or an oil cooler. I usually use durablend valvoline synthetic blend or castrol synthetic blend.

Mobil one is good, but again, I just take good old fashioned synth-blend. If your oil system is working properly, in OEM condition and your motor is operating at the right temps you will be better than fine.

This cocktail has kept my stock container bottom end performing great and consistent for the past 2 years at hp levels around 500 brake horespower.

I used to make the mistake of using weights closer to 50, but you don't want this because the engine was designed with oil passages / diameters etc in mind for a specific viscosity

royal purple makes power at the expense of your equipment.

what is that based on? everything i've read about royal purple is positive in every aspect but the price. if there's research behind what you said i'd like to see it since everything im running this oil in is at risk

VQMaxFan

Castrol 10w40 works fine for my sr.

Its somewhere around here, it was in part 2 of the magazine someone put on here ill look for it i guess.

From what ive heard their viscosity's are off also.

rb25_s13*CHUKI

I run 20w-50 and It works just fine.. Even In the morning

I use the same oil. It's kind of hard to find sometimes though. But it's great for my climate. And the cold weight of 0 gives you geat startup protection.

Ive had always thought of Castrol being better than Mobil 1. IMO

That Castrol European blend is what smelly is talking about... Good stuff I heard, but I think Royal might edge it out a little. But Man amsoil is really good stuff, but at almost 2x the price of Royal, I'd rather just change it more often....

EXCEPT - smelly happens to be an oil nerd on Bobistheoilguy.com - and Royal purple has less than stellar protection. Used Oil Analysis shows that MOBIL ONE 5w30 Protects MUCH better than ROYAL PURPLE 5w30.

The German made castrol is very close to AMSoil - better than mostly anything. The royal purple wont make any more power than mobil1. The Mobil1 and RP will however make 1-2 hp over the FAR BETTER PROTECTING GC 0w30 (which is borderline 40 weight btw)

the only strange thing about mobil1 is that it often comes up with a lot of lead and other metals in it.

Royal Purple is mediocre for protecting, Mobil1 is better, as is pennz platinum and GC.

Amsoil is easy as hell to find, I don't know why you guys keep saying good luck getting it. That may be because my dad is an amsoil dealer, but I'm not so sure after seeing his paperwork from amsoil. It looks like almost anyone could become an amsoil dealer, and looks like an MLM. I believe that is what people mean when they say amsoil is the kirby vaccume cleaner of oils.

Since I drive early in the morning and late at night, even in northwest florida, it gets cold (was 1C this morning) so I run amsoil 10w-40, but in the summer I run 20w-50 amsoil. I wanted to try the RD50 they recently released but I couldn't find any real solid info on how well it would do in a DD since its their racing 15w-50 oil, and with amsoil prices, the extended oci's are somewhat nice.

Oh and my bearings are not facory clearenced, I stole the idea from Matt Back, and am running clearences as large as his are and I also have the mazworx main oiling mod.

heres something i posted from one of the many many other oil threads...
http://www.rpsportengineering.com/OilTests.pdf


edit: oh well the link is no longer working =/ try looking at the previous oil threads

The thing about amsoil is that ur local shits wont carry it - ever. they forbid any chain from selling it.

So its not hard to get-just not worth it for really expensive oil.

great product, just harder to justify.

The german castrol however will be at most autozones. MAKE SURE U GET THE RED Square areound 0w30 - and it says made in germany on back (the USA made 0w30 went out of production in 02 so mostly u'll see german made anymore)

Pennz Plat and mobil1 is everywhere and Pennz u can get crazy deals on.

Really? There are a few stores here (car quest comes to mind) that have it stocked on their shelves. Maybe they are small enough to not get noticed. I've got to drop my oem pan today to switch to a different one, I might have to try the 0w-30 when I do.

i just have to say this ROYAL PURPLE SUCKS its good for low hp engines hondas worked wonders in my friends but if your pushing it fuck that shit. and yes i can back up what im saying.

we used it in out 1000 hp camaro and lets just say after 2 runs it turns to water. and lets just say that engine did not last long at all. then after talking to a bunch of top guys they swore by this stuff called Penn Grade 1 Racing Oil and its been great for about 2 years.

so i just put it in my ka-t and im gunna give it a shot anyone else use it?
