Premium or regular....

as gas prices rise (and hardly) fall, I'm curious what people are putting in their tank. Yes, some vehicles require it but who runs premium...required or not??

I run premium in all my vehicles... Two of them require it and the one... Well... The one just gets horrible mileage if I don't use it...

Regular does it for me. I may try premium in it one day but it seems to work fine as-is.

don't do it man...1 time is all it takes & you'll be a fiend like the rest of us!

1 car requires it, 1 car is spoiled with mid, & the pack mule wagon gets regular :screwy:

Lol, I'll stick with the cheap stuff.

Regular. But I've only ever owned, or driven regularly, low compression non-turbocharged cars. Occasionally (once or twice a year), I'll put in some premium, but if I absolutely have to stop at a station that uses some kind of extra additives in their gas. Figure if I have to stop there, might as well use their product to it's fullest. Otherwise, it's a huge waste of money.

I know people who use Premium in everything they drive, even their "beaters". Over the years, I've heard MANY people claim that using higher octane gas gives them a better MPG. But I think it's more that they tend to be a little lighter on the throttle, when they are spending more ;) But seriously, I've heard people claim that even back when gas was 98¢ a gallon (makes me feel old that I remember driving back when gas was that cheap, and I've only been driving for 12 years).

When I started driving I remember paying 1.09 a gallon... Back then I could drive for 2 weeks on $15 with the Firebird... Fast forward to now... Vette sucks up about $50 a week in gas. :(

All three get premium since they require it.

Regular works fine for me as long as there's no ethanol in it.

My vintage '60's stuff need premium due to their high compression (although they've all been in storage for a few years now.)

My '97 Caddy needs it, as per factory recommendation. It got regular once by mistake. It rattled like 8 rocks in a tin can and fuel mileage dropped by 15%.

My vehicles from the 70's and 80's do just fine on regular.

Track car gets premium (since it requires it), daily gets regular.

the higher the octane the slower the fuel burns it is more of a controlled burn and is better for higher compression motors. i run a high octane in my dodge because of the higher compression ratio and the rest of the vehicles just regular fuel most newer cars have knock sensors which automatically retard the ignition system so detonation will not occur.

In general, if your car doesn't recommend premium, running premium will actually get you WORSE fuel mileage, as you will end up with a slower burn, and more unburned fuel. Even on knock sensor cars, they will reduce timing for worse fuel, but won't usually increase timing past what the recommended fuel rating is so you won't see any benefits from premium (so it's not spoiling your car to run it if it's not recommended).

Happily, both my Mustang and my MINI recommend only regular, so that's what I run. The BMW recommends mid grade, but runs fine on regular, as well. My Range Rover ran fine on regular, so long as it wasn't towing. When towing, it could knock, so I used premium to counter that (which sucked, since it got like 10 mpg when towing)

Ahh! I stand corrected then, Thanks for clearing that up.

I selected all of them because i'm that awesome.

I run midgrade regular is just to "dirty" as I have heard. My car says it detunes for regular but I will stick with premium or midgrade.

one needs premium, one doesn't, one doesn't get driven much but likes 100 octane:naughty:

I use premium... not by choice. I wouldn't even bother posting as I am once again playing Dr. Frankenthread but the guilt of voting without posting (read: whoring) was eating me up inside.

My daily driver and temporary rental car are both getting regular. However, my Stuipdru Forester has a documented intolerance for ethanol greater than 5%, and if I can find cheap gas at a non-ethanol station it gets regular, but 10% ethanol stations means I have to go to mid-grade to avoid knocking... Yes, its that much fun.

i use premium for my motorcycle and regular in the truck

Premium coz the car requires it.

It depends what type of gas your car requires. My car requires Premium so thats what I pump, I've tired regular before and noticed I got terrible gas millage and the car felt sluggish.. If your car calls for Regular fuel running premium will offer zero benefits and may even cause you to get worse gas millage. Some cars designed to run Premium fuels will either say "Premium fuel recommended" or "Premium fuel required" If its only recommended you can safely run regular fuel with a slight performance loss. If it says its required than you have to bite the bullet and use premium.

I daily drove a supercharged Grand Prix for six years and ran premium because its what the car required. I technically could have ran regular and the ECU would have tried to compensate, but it wasn't worth the risk because even though the ECU can try to compensate it doesn't mean I wouldn't have met Chip.

I currently drive a Lancer GTS. It just calls for 87 so that's what it gets.

As has been mentioned multiple times in this thread running higher octane than required offers no benefit other than to take more money out of your wallet. 93 does not clean the engine out, nor does it burn cleaner.
