You only need premium on cars that have high-compression engines or engines with forced induction (turbocharged, supercharged). If the compression ratio of the engine is over 13 to 1 I would use premium. However newer cars have sensors in the engine that will automatically retard the timing if regular gas is used. My cousin has an 08 accord V6 sedan and his manual recommends the mid grade 89 octane. My turbo VW uses premium only. If I use regular my engine loses power, there is less boost and fuel economy is reduced significantly.

I have a 2003 Accord EX-L Coupe with the V-6. The owner's manual calls for an octane rating of 86 or higher. I use 87 (regular unleaded) all the time and find that there is no reason to use anything higher. sometimes a car will run a little better with 89 but I chose not to pay for the small difference in performance that the extra 10 cents per gallon buys you. as for Honda, they say use anthing higher than 86.































hope that helps
