I've been wondering if some companies fuels are better for mileage than others, and if the octane rateing is worth the extra cost for improved mileage. I drive different routes to different job sites, so can't keep an exact record over the same route every day.

Yea, Arco is pretty bad even though it's a subsidary of BP, which isn't too bad.

There are fuels with better additives, they might not improve your mileage, but should keep your fuel and exhaust systems cleaner which won't hurt your mileage. www.toptiergas.com
Octane rating is not power, it's means it's more difficult to ignite. High performance engines compress more air and gasoline, 87 octane will probably detonate while before igniting (pinging). If your car owner's manual doesn't mention "higher octane will improve performance", don't even bother using more than regular.
How you drive, and avoiding stop and go (city) driving makes the biggest difference in mileage.

I drive the same 110 mile round trip every day, and I've noticed that BP and Sunoco tend to get the best mileage out of anyone. Firebird, Valero, and Citgo aren't too bad. And Marathon and Speedway are the worst. I'm not sure if it's additives in the different fuels or what.
But as for driving with a different octane, always use what the manufacturer suggests. The engine in your vehicle was designed to use that, and you may void your warranty if you use a different octane. You'll actually notice no mileage difference between the different octane, and in some cases, depending on the size of your engine, you'll see a decrease in fuel mileage.

Octane rating has to do with the ignition temperature of the gas. It does not affect gas mileage. If your engine doesn't have knocking problems, more octane won't do you any good. So don't use it unless your manual tells you to.
Most fuel in the US is wholesaled by the same large companies and sold to retailers, which may or may not be affiliated with them. So in general, I seriously doubt if there would be any difference. How you drive and what car you drive is much more important in determining fuel efficiency than what fuel you use.

Actually I found I got better gas mileage from Union76 gas over Arco. But you have to pay a little more.

Hyundai has made super advancements in its shape as of previous due; even with the incontrovertible fact that, you nevertheless get what you pay for. the in the motor vehicle looks low-value and its resale value isn't the main suitable. I say you may pass with a Toyota Corolla or a Honda Civic at the start. they're extra depenable and that they do no longer depreciate in value as immediately.

no it is the car and how you operate the vehicle.
