Hey guys. sorry this is kinda NoOb question but i was wondering since my 98civic ex is now turbo charged do i have to use some different kind of oil than is recomended for my car. I was told use synthetic and the same viscosity rating as before.

 

wow read some more

 

ya use 90w gear oil for the turbo
make sure it DOSE NOT mix with your engine oil

 

what an -------! Just use the regular 10w-30w that's what I use. Been turbo'd 3 years now, no problems. Car runs like a champ.

 

10w30 is fine for cold climate winter driving...but when it warms up step it up. I usually run 15w40 in mine in warmer weather.

 

Just use 4 quarts of ---- Ease. You know the ---- you use in your butt before you get fucked in it, ricer ***

 

10-30 sucks for turbo cars.

you want the last digit as high as possible.
The higher the last digit, the most viscous the oil will remain in the turbo.
The 10-30, get's runny like water when it hits the turbo, this is much hotter than a n/a engine...lubrication of the turbo is reduced, so chances of premature turbo wear and oil leakage / smoke are increased.

I use and recommend 5-50 oil. I think it's only available in syntetic.

 

5W-50 is a bit hard to find, and from what I've heard oils with that big of a gap break down faster. Who ------- knows though, I had a oil light one night working so I dumped some Castrol 5w-50 in there... worked well afaik, didn't have problems with it until the water pump went out so I just yanked the whole motor.

 

nah, the whole point of getting 5-50 oil is to slow down oil break down.

 

i always just run my oil until its getting black, and the pressure drops a few psi at idle.

fresh oil drive is around 71psi, old oil is 60-65ish.

fresh oil idle is 49-52. old is 42ish
