Not really. Fill up with the "correct" octane when you run some fuel out of your ride.
91 octane or higher it actually depends on how out your engine block gets but most cars use 87 octane, unless your car is running hotter th 200+ degrees you dont use 91 octane, your car would loose power from running to rich
You should use 91 or better or will result in knocking.
I would use 91 octane gas. That is what I used in my Honda Elite 150.
for any Volkswagen gas engine do not use anything lower than a 91 octane rating.
A 2002 Volkswagen Beetle Turbo takes 91 octane gas or higher. The manufacturer's recommended octane for this car will also be listed on the inside of the gas cap.
Premium, 91 or higher
yes only use what the car recommends. anything less and the engine will knock, anything more and you will only be wasting money, high performance gas only works with high performance engines.
Use 91 octane or higher octane rating premium gas for the 2009 Lexus RX350
That's what you're supposed to use.
Yes you can. If your local gas station's premium fuel is lower than 91 go with it and stop by your local car parts store like auto zone and by an octane booster. You will need one with every tank of gas. But if your gas station has 91 or hopefully 93 then you will be set. But an octane booster will help even more but is not necessary with the 91-93 octane
91 octane my broda
