What brand of gas do you use?

[Ray]

The Boxster engine is designed to take a higher octane ... it has a higher compression. I use Sunoco 94

[Gary in BR]

I use Chevron or Shell.
I prefer Chevron but there are more Shells around here.

Obviously we'd all like to run lower octane and save some money, but if that puppy is pinging it means significant damage to the engine is happening. One of the easiest ways to begin such a process is to look at your plugs running premium and see if they are wet and carbonized.

I was just kidding. I use nothing but 93 octane for my baby. My mazda 3 on the other hand gets the the cheapest gas I can find.

Chevron, Mobile or 76, 91 (best we got) octane in that order.

I luck out. The HESS station three blocks from home has the lowest prices within an hour's drive. I haven't paid more than $3.20 for 93 ever.
I can't believe that's supposed to be a good thing.


Which reminds me time to buy some more stocks in those companies sitting on a five year high of supply yet them prices aint coming down!
I guess they make more money at higher prices on lower volume than higher volume at lower prices.
Great for them bad for the overall economy as the price to ship food, jeans and toilet paper brings on inflation.

p.s.
And in 50K miles me BoxsterS has never once tasted anything less than 93.

91 octane / 13.813 gal / $3.499 per gal / $48.33 at Costco yesterday.

265.5 miles => 19.2 mpg

I figure I could get another 2 mpg if I didn't hit 90+ mph coming and going on my commute every day

I hope you guys realize that the gas stations you are going to are not getting their gas from the same people all the time. They source the cheapest gas available to them from many different sources. In the end it all ends up the same really. It's more about who's got less crud coming through their lines.

i've never been to FL, so I don't know if the refineries are there too, but we have refineries about 30 miles from here, and I know people that work there. there is a difference. and while 1 refinery might supply fuel to 3 different brands of fuel, the additive packages that go into the fuels are different.

BP: 93 octane

I do believe that BP does not use Hugo's oil too! As well as middle east.

We don't have any here where I'm at, so you get lots of vendors hitting the local gas stations. BP could have great gas one day and the next week it makes my cel trip. I usually use an octane booster as when I was in Germany last I noticed the gas there starts at like 96 and goes up to I think 101.
