Just installed the greddy kit not to long ago and i was wondering if anyone would recomend something defferent than 5w-30?

 

10w-30 if the weather isn't too cold.

 

10w30 mobil1 for my boosted y8

 

Regular Castrol GTX 10w30 for me.

 

I used to run mobil 1 until I realized $5 a quart sucks

 

10w30 Mobil1 here... I'm lucky I work for an autoparts company so I get it for cheap

Or else I probably wouldn't buy it...

 

non-synthetic oil's correct? cause as far as i know synthetic oil run like water on turbo cars which is back for the turbo and can eventually cause it to seize up but it's just what i've herd not what i know might be different for mobile 1

 

Castrol GTX High Mileage 10w30(summer), 5w30(winter)

 

damn you guys should use a thicker oil especially if you runs forged pistons...

Castrol syntec 15w50 in my car... Mobil 1 is too much liquid when she gets hot !

 

bump for some more info in thicker weight for a turbo D And to clear up if synthtic is bad for turbo?

 

I run mobil 1 synthetic 10w30 on my turbo d16. They are right though...its super expensive and runs like water out of my leaks

 

i use castrol gtx 10w-40

 

Anyone wanna confirm this is any better to run than 10 30 ? Im thinkin about synthetic blend castrol stuff ...

 

i'm using mobil 1 synthetic 5w-30 in my d16z6-t. sometimes 10w-30.

I use full-synthetic oil, but I'm thinking about changing to a synthetic blend.

I don't understand why synthetic oil would hurt a turbo application? I use it because it can run hotter than conventional oil without breaking down. I have read in a few different books that only synthetic oil should be used in turbo applications because it is more resistant to coking.

How would synthetic cause your turbo to seize?

 

I Think Im going to start using castrol Syn Blend also

 

I was told to use 10w40 for my engine with forged pistons. Mobil no longer sells the regular 15w50, which was an excellent oil. Now it's a different formula sold under their "extended performance" line. They do make a 10w40 EP, but I haven't found it anywhere. If you happen to have a Pep Boys near you, you might want to see if they still have any MADD coupon calendars for sale. They're $1 each, but inside there is a coupon for buy 3, get 3 free Mobil 1 (I think that's the amount), but anyway I bought a stack of calendars a while ago. Hopefully they'll start selling the 10w40 EP.

 

Mobil 1 10w30

Synthetic oils have superior high temperature oxidation resistance, high film strength, very low tendency to form deposits, stable viscosity base, and low temperature flow characteristics and besides all that is a better lube than dino oil. In fact thats why some don't advise use in break in....too slick!

Mobil 1 doesn't use viscosity improvers (polymers) in their 5W-30, and I would assume the new 10W-30.
