Can i jump around between premium gas and mid grade?...or should i just stick to one type?
in some places that isn't too bad if your car takes regular. Last time I was in northern Missouri on vacation one place I got gas at actually had premium cheaper than regular, so while I was there if I was around that place when I needed gas car got premium.The only reason I'd know of why you wouldn't is because when you mix premium and regular you end up somewhere in the middle and don't get the full benefit of paying premium unless you stick with it over fill ups. Say you're at a half talk of 89, top off with 93, you're left with a full tank of 91 octane. Of course you can wait til your tank is closer to empty so the effect isn't as bad.
http://www.ftc.gov/bcp/edu/pubs/consumer/autos/aut12.shtmAre you tempted to buy a high octane gasoline for your car because you want to improve its performance? If so, take note: the recommended gasoline for most cars is regular octane. In fact, in most cases, using a higher octane gasoline than your owner's manual recommends offers absolutely no benefit. It won't make your car perform better, go faster, get better mileage or run cleaner. Your best bet: listen to your owner's manual.
The only time you might need to switch to a higher octane level is if your car engine knocks when you use the recommended fuel. This happens to a small percentage of cars.
Unless your engine is knocking, buying higher octane gasoline is a waste of money, too. Premium gas costs 15 to 20 cents per gallon more than regular. That can add up to $100 or more a year in extra costs. Studies indicate that altogether, drivers may be spending hundreds of millions of dollars each year for higher octane gas than they need.
well that is all fine and good but the question was not SHOULD but COULD he? and the answer to that is yes you can and not damage your engine. Frankly I buy whatever is cheaper and will fit my wallet when I need gas on my daily Driver. my cars that require premium obviously get it since they NEED it lolStraight from the FTC:
There's more to read on the website. But basically, stick to 87.
That's kind of funny that you would point that out to me when you said the following on page 1 (which was the very first reply to this thread):well that is all fine and good but the question was not SHOULD but COULD he?
Emphasis mine. I don't know why you're nitpicking my post when yours is of the same construct, albeit with less information.I know of no reason why you shouldn't. Gas mileage may change a bit as you swap around but that's abou it.
in my post shouldn't / couldn't can be used interchangably. There is no reason you SHOULDN'T run premium meaning it will not hurt your car. There are lots of reasons why you SHOULDN'T run 87 in a car that is tuned for 93.That's kind of funny that you would point that out to me when you said the following on page 1 (which was the very first reply to this thread):

Love your username, but it doesn't match with your ridiculous signature.Haha ^^^THIS. Higher octane in a stock car that calls for 87, is a waste of money. Do some research.
