What oil does eveyone with forced inductions use?
What type brand and viscosity rating. Are you guys changing the rating to a heavier oil?
Would something like 0w40 be appropriate for a turbo or sc engine?
Does toyota recomend switching to a different oil after installing the sc?

manual says 5W-30
Since you are in Phoenix you can get away with heavier oil. But I go with what the manual says, and TRD states to continue to follow their maintenance procedures. So 5W-30 it is.

I am in Az, I run a 10w30 winter and a 10w40 summer. All I use is castrol syntec. Have used it for about 8 or more years now on all my cars. Awsome stuff.
Once morning temps are above 70F I switch over to 10w40. Under than I use the thinner. Running 5w oil in a forced induction engine is just nuts to me and will probably result in much shorter engine life overall IMO.
When I switched over to 10w30 there was an immediate difference in engine sound, engine was glass smooth without all the rattles, clangings and other engine related noises. Even more so with 10w40. I always let the car heat up before running over 3K rpm. Engine really responds well under f/i with slightly thicker oils, especially sythetics. Just knowing the metallic sounds from the engine have stopped means there is allot more cushion between parts.

Here is a little tidbit of info.
You decide what is best for your conditions.

What grade of motor oil do I use in my car?
Check your owner's manual to select the correct SAE viscosity grade. Your car manufacturer will specify different grades of motor oil based upon the temperatures in which your car is being operated. Chevron Supreme Motor Oils come in a variety of SAE viscosity grades. As a guideline:
SAE
Viscosity
Grade Cold Starting
Temperature
Conditions Descriptions
5W-30 -13 F Provides excellent fuel economy and low temperature performance in most late model automobiles. Especially recommended for new cars.
10W-30 0° F Most frequently recommended viscosity grade for most automobile engines, including high performance multi-valve engines and turbo-charged engines.
10W-40 0° F The first multi-grade introduced. A good choice for controlling engine wear and preventing oil breakdown from oxidation due to hotter-than-normal running conditions. Note: Always check your owner's manual or warranty requirements before using this grade.
20W-50 15° F Provides maximum protection for high performance, high RPM racing engines. Excellent choice for high temperature and heavy loads such as driving in the desert or towing a trailer at high speeds for long periods of time.
SAE 30 15° F For cars and light trucks, where recommended by manufacturers.
SAE 40 32° F Not recommended when cold temperature starting is required.

Yeah im running 5w-30 Mobil 1 Synthetic, but im thinking about going with ROYAL PURPLE.
Anyone used it before? Also from reading other posts it loos like i will switch to 10w-30 since im TC.

a good one for turbo applications is Greddy's GR-2 5W-40 synthetic oil. I'm sure it could be used for superchargers too because it's a forced induction (low to mid boost range) oil. I use it on my other car (97 Eclipse GS-T) and it's a really good oil. Also Mobile has a good synthetic oil.
