Hey Everyone,
Last year I switched my car over from 87 to 93 octane. According to Hyundai the ECU can adapt to higher octane fuel and allow the motor to produce up to 10 more horsepower.
The manual reads:
"Your new vehicle is designed to use only
unleaded fuel having a pump octane
number ((R+M)/2) of 87 (Research
Octane Number 91) or higher."
I was running 87 for 15,000 miles and didn't have any problems. Now, the reason I switched is because many people recommend higher octane fuel for turbo cars. But now I'm wondering if I'm just wasting my money at the pump. I've seen some dyno charts that show decreased power on 87 but I've also seen good runs on the same octane as well.
So I guess the question is, should I continue to use 93 or switch back to 87?
-Thanks
