Regular or Premium Gasoline?

I was wondering about this today and the SUPER SPECIAL Shell 307 Octane was only $0.25 more than my Regular gasoline.

I usually put in about 10 gallons every time I fill up, so is $2.50 more per tank really that much more to pay for super awesome gas? I only fill up about 3 times a month right now (I live on campus) so that doesn't add up to very much.

I have a feeling most of you will tell me that premium gas really doesn't do much for you and it's not worth the added expense. Well, to figure out if it's an added expense, I would need to figure out how much I am paying per mile I think. The last tank I paid about $0.103 per mile on Regular. I will have to see what it goes to on Premium.

I'm also wondering, because I drive a 1995 Pontiac Grand Prix with 280,900 on it, and I'd like to do whatever I can to primp her and keep her running into the 300,000. I have no reason to doubt her making it. In the last two years I've needed an alternator, brakes, and an intake manifold. A grand total of less than $2000. Not bad, if you ask me.

So what is it folks? Regular or Premium?

Many higher end cars REQUIRE premium gas so its not like its a choice for many people.

My dad told me that unless I drive a car that specifically requires premium gas (and says so in the owner's manual), not to waste my money -- it's more important to get regular oil changes and maintenance.

I do understand that some high-performance and luxury models require premium gas.

Premium is less likely to self-ignite under compression (knock). This is only important if you have a high enough compression engine that it is knocking under load. Very few such engines are produced any more and they make a big deal of needing premium in the owners manual.

The oil company "more additives" "better for your engine" crap is crap. It burns slightly slower, starts slightly harder, and is less prone to knock. If your engine doesn't knock, don't waste your money.

You won't get better mileage BECAUSE of premium, but if you EXPECT to, and drive more conservatively, you may get a Hawthorne effect.

See your owner's manual.

If it doesn't require premium, don't bother.

Finding out that my new car takes regular gas was as exciting as getting the new car to begin with.

My first car, a 1993 VW Fox, actually REQUIRED the cheap stuff.

The previous owner said it didn't respond well to premium, but I unwittingly selected the wrong grade at the pump once.
Five minutes later, the car stalled out on the highway.
It was fine after a few minutes, but that was the last time I made that mistake.

I'd put up with 5 years of knocking to save the huge money I would on dropping down a grade of gas.

I chatted with actual VW engineers from Germany and they told me to never use anything but regular in our old Jetta. They said the engine was tuned for regular ... but I don't know anything about engines...

My engine requires at least 89 because it's turbo-charged. It runs very sluggish if I try to put 87 in it. Sucks for me cause we're just about at $3/gal again.

The Fox was a re-badged Audi, so the engine specs might have been significantly different to warrant a different formulation.

I thought I read the post to say his Fox only ran on regular without stalling.

Only if your Grand Prix is supercharged and requires 91+ octane premium like mine.

Otherwise, save your money.

BTW: Out of curiosity. Does your Grand Prix have the 3.8L or the 3.1L or something else? Just curious. I know the 3800 engines last forever, but geez, you're pushing 300k.

It's odd, my Altima manual says to put in premium... and I've read that engine performance will go down if I continually put in regular, to the point that going back to premium won't bring it back up...

3.1L.!!

Yeah, I have made several cross country trips with her the last two years. Twice from MN to TX (20 hours), once from TX to AZ (13 hours) and once from TX to CA (20 hours). I'm a little concerned though, because I have to move next month. I am going to MN first then driving to CA. I am hoping to avoid the mountains because it's likely I will be pulling a small u-Haul trailer.

My only complaint is that the temperature gauge claims she is close to overheating if I sit idling long enough...especially in stop-and-go traffic. Hasn't overheated yet, though.

For my cars, it's regular. For yours, premium. Why? I pay for my cars, you pay for yours.

My owner's manual specifically recommends 91 (which no one outside of Sunoco sells) with a minimum of 89. I've put 87 (or badly-blended 89) in and it did cause knocking which was confirmed by my mechanic. I put in premium and the problem went away.

But that's my car (a 1996 328is). I don't know if that's the same for yours.

I have a 01' Honda Prelude that requires 91+ but have been using 87 ever since the first $3.00+ spike. I drive very conservatively and haven't experienced any knocking that I'm aware of, and still get 30+ mpg. I'm very careful about not pushing the car, and rarely if ever get the RPMs high enough to initiate the variable valve timing. Maybe next time I should use Premium and make sure I'm just not used to how the car's been running.

Only $3?? Here it is $3.50 for the low octane stuff... a few days ago it shot up $0.12 in one day!

Ever since I read a thread on this quite a while ago, and had OldDude explain it, I've been using regular in both of my cars. I still put premium in my bike, but at only a few gallons a fill-up, I don't really notice the cost.
