which oil weight to use..

[norcalslider]

i read around a seen a few things on weight so im not sure which weight to run in these motors...my guess would be 5w-30 because of the turbo and i want to run castrol edge.will i be fine running that weight?

[RedSiBaron]

sorry what motor are you running?

[djcobra]

umm no... more like 10W-30 for our Turbo cars. Higher the viscosity, the better. 5W-30 is too thin in my oppinion. The turbo will cook the hell out of that grade!

Check the FAQ next time before you get flamed.

[norcalslider]

sr20det..i just bought castrol edge 5w-30

[Jonnie Fraz]

If you would like incredibly in depth and boring read on oil here ya go.http://www.supramania.com/aehaas/

[norcalslider]

well since already bought this oil will i be ok to run this for now then?

[RedSiBaron]

you do realize that proper lubrication in an engine is essential for proper function and heat management right? and the problems of proper lubrication are exacerbated by forced induction, higher revs, higher compression, higher hp, etc etc right?

taking a "What the hell!! it'll work good enough!!!" is a pretty ill advised approach to oil...

[norcalslider]

yes i know..but i thought since i ran 5w-30 in subaru wrx and this motor is turbo'd also it would be fine...i also read that 5w-30 is the recommended oil weight for this motor..so if not this weight then what one should i be running then?

[CaptainVlad]

I bought some Eneos 0w50 that I plan to use when Spring comes around. I guess I will see how that works out.

[RedSiBaron]

all engines are different, 1 turbo or 1 n/a to another isnt made equal..theres more than one way to skin a cat, it just depends on how those industrious japanese engineers decided to make the cat go faster haha...if they suggest you run 5w30, then thats what id run, unless of course someone here says "well wait, heres a problem with running that, and heres why"

for instance on my 2002 civic si, honda suggested running 5w20 but we discovered that it would cause cam gauling issues and honda only did it for economy, and instead running 5w30 was the correct weight, but you wouldnt know that unless you ask...

sorry for jumping on your case...i was just in a touchy mood because on another forum i have some kid making threads on top of threads post whoring so he can sell and im a mod and he just came back from a ban today...grr

[norcalslider]

i see where your coming from,i just dont want to fuck my shit up and be down for awhile.what weight are you running on your motor or sr.

when i had my wrx i ran 5w30 with no problems at all and felt really good too but thats a different motor also.

Its cool man i have thick skin for this crap..and no im not here to post whore,i just make my thread to get legit answers when i cant find anything when i use the search box.

[S-Nation S13]

5w or 10w its up to you,but really if you want it to the book, fsm would have your answer...

[norcalslider]

whats is FSM

[S-Nation S13]

Factory Service Manual...
www.240edge.com theres the link you should keep this handy...

[norcalslider]

dude your the man!

[S-Nation S13]

no problem, just wanting to help out when i can...

[norcalslider]

either im blind or it doesnt say what oil weight to use.

hahaha i wasnt comparing you to the guy on my other forum

ive just been throwing some valvoline max life 10w30 i had sitting on my shelf into my ka24e...the motors a sack of crap, i think thats the right oil to run in this engines case, it has 170kish, and i ran this stuff in my 86 civic si from 320k to 365k beating it to death and it never gave me one hickup...hopefully i can get the seals to soften up, its slowly burning less oil as ive used the max life but its still dropping a quart every 800miles (it was doing it every 600, so its not as bad as it was) haha its not leaking, ive checked, its just burning oil

[norcalslider]

oh i see..well since i already bought this 5w30 and read a few places its a recommend oil then ill switch to 10w30/40 in castrol edge

[KaminaSan]

If you run 5-30 in your car, and you live in a place where you see 90+ temperatures...

I would give your SR about a month to live driving on city sreets, and after a road trip/hour drive, you will probably spin a bearing.

It even has a *5w-30 note in the FSM, saying 5w-30 is 'not suitable for extended driving*

10w-30 is acceptable, 10-40 is a good balance. 15-50 is the best, but offers shitty cold starts.

[norcalslider]

see i couldnt find those answer in the fsm maybe i DL the incorrect one..but those where the answers i was looking for so maybe ill take the oil back and get the correct one of 10w30 in castrol.....or better yet what about Rotella t5?

[jamg]

shell rotella T

well if you look in the fsm, it will more than likely show a chart that indicates the ranges for the oil combos based on average ambient temperatures for start and operating temperature...10w30 is good for winter, then id run 10w40 in summer, or if you live in really hot weather, like average over 90degrees, id run 20w40, 20w50...or like you said 15w40/50...isnt 15w50 a common bmw weight oil? i remember my friend running something weird like that in his old e28 bmw and always had a bitch of a time finding it

honestly if you really want your engine to hold up to high temp and high stress conditions, you absolutely cannot go wrong with redline oil...my father has been running it for nearly 50 years in his racecars and high performance vehicles and i run it in all my street cars and its fantastic

[homeslicej2]

I have a copy of the FSM (S14 SR) and there is indeed a graph showing what weight oils to use depending on ambient temp. It does say that "5w-30 or 10w-30 is preferable regardless of driving conditions" but the graph shows that you shouldn't use 5w-30 if the ambient temp is above 59 degrees fahrenheit. I use 10w-30 in the winter and 10w-40 or 15w-50 in the summer. I live in GA where it gets hot and humid.

[Flipzide]

i use 20w50 castrol oil or amsoil in my s13sr w/ a 19row oil cooler, but it's used at willow springs in temperatures of 100+ degrees fahrenheit in the summer. no problems for the past 3 years.

i also use 20w50 in my daily driver ka s13 in san diego. no problems in 6 years.

brian..are you fucking serious 20w? in a ka, shit thats some thick ass oil bro, did it get rid of the infamous timing chain rattle lol im curious to know

[singlecamslam]

i use 10w30 on a rb25.

[TheRealSy90]

I've been using Mobil1 15w-50 full synthetic for three years now. Not a single problem. I use it year round too.

[norcalslider]

honestly if you really want your engine to hold up to high temp and high stress conditions, you absolutely cannot go wrong with redline oil...my father has been running it for nearly 50 years in his racecars and high performance vehicles and i run it in all my street cars and its fantastic

dude redline is the shizznit i love that stuff but its so damn expensive.i ran it in my wrx tranny and the moment i ran it my 3rd gear grind was gone asap...which redline are you running?

[S14DB]

This thread is lol worthy with people arguing over winter grades.

Motor oil - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/Motor_oil#Grades)

[norcalslider]

alright so from all the post im getting ive seen no know post any 5w,so that leaves me no choice but to exchange for the correct oil in the 10w catagory...oh and where i live we only in the 50-60's right now but when summer hits 90+

I dunno, id call this thread pretty much a discussion rather than an argument

[norcalslider]

I dunno, id call this thread pretty much a discussion rather than an argument

i agree with this^

[KiLLeR2001]

I'm in Florida and I use 10w-40 (sr20det). I noticed that 10w-30 was a bit too thin... I want to try 20w-50 for this upcoming summer but I'm not sure :|

[norcalslider]

alright i took the 5w30 back and got some 10w40 castrol syntec cause they dont have it in edge..so tomorrow is jiffy lube day

Mobil delvac diesel motor oil

[JuMPiiN]

Mobil 1 full synthetic 10-30 here
And royal purple 75-90 for tranny.

[norcalslider]

you might as well use rotella t5

[norcalslider]

Mobil 1 full synthetic 10-30 here
And royal purple 75-90 for tranny.

why purple? i cant stand that shit,it should even be on the market it sucks soo bad..i tried it in my wrx for motor oil,tranny,rear diff and all failed,the wear protection is weak my tranny almost died because of it and my diff clunked and whinned. im just sayin i say run redline

[JuMPiiN]

Not really sure, can't really find redlie where I am. And RP seemed to be the best bet, it's just my DD no drifting or anything going on here.

[norcalslider]

you can have redline shipped to your door..here is a funny thing im an amsol dealer where i live and use other stuff idk why but ive always used castrol..maybe im just used to using amsol in my quads.

[JuMPiiN]

Yes I know, I'm just not one for waiting. I like RP, idk why I just do. I like mobile 1 as well just a preference.

[karl wasabi]

shell rotella T

15-40

YES! This is what I run in my RB20 and BMW. Love this stuff and it's cheap too.

[Q.Smooth127]

10w-40 or 20w-50.
i normally use 10w-40, but i just switched to 20w-50 cause i went for a dyno tune recently n the bugga runs fine wit that oil.
10w-40 is the safe oil for just balance.
good to hear you got rid that 5w-30 crap. This isnt a honda motor which nobody gives a s*** about :p

[Tantwoforty]

glad i ended up here..
i have a freshly rebuilt ka-t
i was planning on running mobile1 full synthetic 5-30
but it looks like that may be bad?
what should i be running on a fresh engine.. bearings, head everything.
note i live in socal, and will daily the car

[norcalslider]

back from the dead..i havent even been able to run the car enough for change the only because of this crap weather we have, i havent been able to drive for a week straight without it snowing.so now im at the point where i can change the oil this time im going to try rotella T5

[negrosx13]

Mobil1 5w 40 on my Sr.. oil thickness vary in temperature..

[HYPNOTIK]

Amsoil Race 15w50 > everything else

[redline racer510]

pentosin 10w-40
or motul 5w-40

[huntington19]

so tomorrow is jiffy lube day


are you insane?? kiss your seals goodbye. :/

[norcalslider]

are you insane?? kiss your seals goodbye. :/

why is this because i want to use T5?

[Silverbullet]

umm no... more like 10W-30 for our Turbo cars. Higher the viscosity, the better. 5W-30 is too thin in my oppinion. The turbo will cook the hell out of that grade!

Check the FAQ next time before you get flamed.

I don't think some of the posters here understand what the numbers actually mean.

10w-30 and 5w-30 will run exactly the same at op temperature. The W number is the viscocity when the oil is cold, and the 30 is the viscocity at operating temp.

Run what the FSM says. Its clear and simple. If your running higher HP and experiences long durations of high HP (400bhp) such as road racing, then I hope you have a oil temp and pressure gauge to assess whether your oil weight needs to change. Short bursts of high HP such as drifting may not be as big of a deal.

[PoorMans180SX]

Wow, I've never seen a thread like this before.

How about you use Google?
