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.

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.

RedSiBaron

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.

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

15-40

RedSiBaron

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

RedSiBaron

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.

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