Petronas has 4 types of oil: Fully synthetic has got 2 types and 1 each for semi and mineral.
Looks like naza has a bulk purchase wif petronas. I know the Pugs are also using Petronas. Not sure bout chevy though.
Engine oil also play an important role in performance besides upkeep. Honestly i dont think petronas oil is tt good based on my butt feel. Petrol yes. Oil no. Ok onli.But then again its a mid range brand.
Dyno has shown tt usage of differrent grade/quality oil (same viscosity) can improve +1 to 1.5 whp based on same car.

yup that 4 for open markets... for kia SC they're using 2 types only...
5w-30 4L for fully syn... for mineral forgot the specs...
my next change want to try MoS2 Leichtlauf - 10W30 - 4L
How flexible are the sc in terms of allowing customers to bring in own oil? I assume your car is still under warranty?
I can recommend a few brands tt is really worthwhile trying out n it wont disappoint based on my experience. Motul n Torco. Both r really good.
