What oil are you guys using in hot climates?
 

Just as the title says, what oil are you guys using in hot climates?

I use Eneos 0-20 here in Dallas.

I wouldn't change from 0w-20 unless you are FI or track frequently. It does fine in 100 degree weather.

I will be using 5w-30 when my SC goes on. Probably Amsoil.

Mobil 1 5W-20 in Las Vegas. And that's really only because I can get it cheaper than I can get 0W-20, plus that I don't need to worry about its cold weather performance.

amsoil dominator 10w 30

Castrol 0w20 full synthetic here in Aus where the temperature sometimes exceeds 40 celcius . Runs fine with factory set up.

MOTUL 300V 5W-30....Temps in middle east hit 50 celcius...

Use Amsoil 0-20 here in Dallas

Lots of good info on oil on BITOG. Bob Is The Oil Guy. http://www.bobistheoilguy.com/forums/

Top rated motor oils I've used:

1. TGMO 0W-20 (Toyota Genuine Motor Oil - Made by Mobil to Toyota specs)
2. Eneos Sustina 0W-20 (Best oil out there IMO but, expensive!)
3. Mazda w/moly 0W-20 (Made by Idemitsu)

I really like the Mazda oil but, am getting ready to do a "CATERHAM blend" using 1 pint of Mobil 1 0W-40 and then top off with TGMO 0W-20. The M1 is suppose to add to characteristics that increase shear resistance due to heat and the 0W-20 keeps it free revving and flowing good! We shall see...YMMV.

Just did Royal Purple 0w20 last week.
