At what point are you going to switch from 91 to 89 or 87 if you haven't already? I paid $4.10 yesterday for 91 so I'm beginning to wonder if 87 and driving like granny will be better for my wallet. Is my reasoning is flawed?

What I'm gonna do is go from paying 4.10-4.29/gal for 91 octane, to just running 100 octane all the time....I don't think it's that much more expensive anymore, I haven't checked in awhile though.

Honestly, yes. You're saving what, $2.50 per tank?
One bad round of detonation from crappy gas can ruin your whole day.
If per-tank prices went from 25 to 50, ok. The difference on a Subie is like $50 vs $52......I have a non-turbo Subie that runs on 87 and a turbo that runs on 91 (and gets the same mileage, :cry and that's honestly aobut what you'll see. Not worth the risk.

Get an echo or a prius. Hey don't knock it but I'm looking for a nice good prius i can drive around in.

wouldn't 87 run less efficient than 91 because it doesn't burn as cleanly/completely?

Wouldn't the AP 87 octane maps prevent detonation and timing issues?

Mr. Furley

If i run 87 my car will asplode

I wont even attempt it, nothing but 91 goes into her honey hole.

Turbo = high octane

Theoretically, yes.
If I wanted a slow car, though, I'd drive my wagon

I, personally, will keep running 91 because the cost difference isn't enough to make me want to cut my performance. If you only have one car, and it's paid off, I can see going to 87 if you don't really care about the performance loss (I've known Eric for a long time and know his WRX is a DD, not a toy), but if you've still got something relatively new and you want to get away from 91, I'd be looking at a different car for a cheap DD before the value tanks on the current car.

Here ya go good buddy..



I saved $8 in fuel today.

Mr. Furley

Now lets calculate your hospital bills and the massive laughfest we had at your expense VS. how much you've saved on gas

I actually made money breaking my leg Disability ins from work + state ended up paying more due to taxes and stuff, even if you factor in the minimal amount I paid for my repairs.

If you really wanted to get technical, the injury also happened on the mountain bike, not on my road bike that I ride mostly on the paved trail with no motorized traffic

You're still looking at worse mileage and less power so that extra $2.50 91 or that extra $x.xx for having to fill up sooner due to the crappy mileage you're going to get from 87. Price of admission to drive a Subaru varies anyways depending on how you drive. Pay to play.

Oh and now that I have a bionic leg, I'm gonna have Paul do an accessport tune on it.

Mr. Furley

Poured a whole bucket of water on my burn
