Hi Guys and gals,
I am about to go to synthetic oil for my JDM STI-7. Been using standard oil for first 10,000 miles but now car should be 100% broken in so time for the switch.
I am correct to assume that for my hot climate a 10 - 30 or 10 - 40 sae synthetic is too thin ? (temp in summer between 25 - 38 degrees C and temp in winter between 15 - 30 degrees C)
My other choices in fully synthetic are 20 - 50, 10 - 50, 5 - 50 ? What would you go for in this hot climate and my JDM STI-7 modded to about 330 BHP ?
Cheers,
Ray
