what motor oil to use for turbo engine?
just a question. i was reading the installation manual posted on importparts.com for Drag 3 turbo kits. and it says:
"Use high-grade oil and/or one formulated for use with turbo motors (DRAG utilizes 20-50W Mobile One)."
why 20w50? isn't that too thick? what are the advantages? disadvantages?
"Use high-grade oil and/or one formulated for use with turbo motors (DRAG utilizes 20-50W Mobile One)."
why 20w50? isn't that too thick? what are the advantages? disadvantages?

I don't know what Greddy is thinking but I recommend synthetic ONLY for turbo applications. It maintains its viscosity better, foams less and prevents coking better than dino-oil. My personal preference is Mobil1 5W-30 running in my 2nd gen CRX with t25 at 8 psi. I have had nothing but good results with the Mobil1 and can't say anything bad.

Re: what motor oil to use for turbo engine? (RGAZ)
I likewise have used nothing but Mobil 1 in both my cars. 15-50 for the GS-R, 10-30 for the Civic. What do you guys reccomend in terms of weight for the turbo Civic? Mind you I live in S. Fla so for 11 months of the year it's about 80 degrees and humid as hell.

I run castrol synthetic 5w30 in my turbo civic. Been running great. 
5w30 is what is recommended by honda for my engine (d16z6).

use mobile 1 5-30
the20-50 is WAY too thick. You lose performance but in hot weather, it protects better.
in cold weather, 20-50 takes too long to flow to the turbo...not a good thing! it's like syrup.

By the way Liam, I hope you aren't doing everything Honda says to do with your car, their reccomended oil change interval, the type of gas, 87 octane, hehe not good if you are turbo'd, etc. I also like that website, damn you, that's where the .com went! j/k

The whole purpose and design of a mulit-viscosity lubricant is that it changes it's viscosity or "weight" depending upon the ambient temperature and the operatinig temperature. Lets take the 20-50 multi-vis as an example. When the weater is the coldest, the viscosity is a 20 weight or the thinnest, not a 50 weight, and as the weather warms up, it will go as far as a 50 weight. In other words, the oil will adapt its viscosity to the ambient air temp and when the engine is warmed up, the viscosity adapts accordingly too.
