Ok, im looking into buying one of these acccord 6-speeds, but the only thing that pesters me is that someone i know told me that in cali, he owns one and never puts in anything but regular gas...is that ok for this car or does it require premium fuel? I know it might sound like a dumb question to some but i really have no clue...

Thanks in advance guys.

 

To paraphrase the owners manual:

Unless you're going to drive like a grandma at engine speeds below 1000 rpm knocking will not be a problem. Use 86 or higher equivalent fuel.

From working in service:

Unless you are constantly going to be racing this car putting anything higher than 86-87 octane in it is a waste on money. And if you're more of a normal driver using 91-92 octane will actually speed buildup of softcarbon in the EGR and engine.

 

damn, for some reason i thought this car required 91 octane, thats cool.

 

Naw, it's not a high enough compression motor to require it. The ECU is more than capable of adjusting A/F mixtures and timing quickly enough to avoid pinging.

 

I dont understand why other more expensive cars cant run the same way, its so annoying, like the camry runs on regular gas, but the es330 runs on premium...wtf?

 

Compare compression ratios on the 2 cars, higher compression usually requires higher octane.

When I had the stock 9:1 ratio on my 350 I could run 89 octane (mid grade) with no problems. When I bumped to 10.75:1 I had to step up to 92 and if I was really gonna run the car, ie. speed trips to the coast. I had to use an octane booster.

 

I actually think both cars share the same motor.
