93 Octane

[delatlanta1281]

So, some of you may have heard there is a little gas crisis here in the southeast. I live downtown and 93 octane is nowhere to be found. My gas light is on and I really want to drive my e30 this weekend instead of my Jetta. Here's the question, I have a MarkD chip tuned for California (91 octane), can I get 87 octane and add "octane booster" to make it run? 87 octane is pretty much everywhere, but I don't want to tool around in the e30 with my gaslight on and not find 93....
TIA.

Do you not have mid-grade? Like 90 or 91? Is it just 87 and 93?

Pour a gallon of tolulene in right before you pump the 87 in the tank.

Where do I get that?
And no the only thing close is 89.
In ga we have 87,89, 93.
Pretty stringent here.

FWIW, I drove my chipped eta through a whole tank of 87 without any apparent issues. It was cold, and I don't really get on it much, so that may have helped.

Hmmm, Don't wanna risk it though. Does octane booster actually work?

[Gooch]

Never tried it, but Xylene is also pretty popular.

Paint store ( like Kelly Moore, if you have those there, Hardware store if not ), it's 112 octane IIRC, octane boost from a store bought can is mostly tolulene and doesn't do shit.

You could get by using crap gas and driving a bit milder while you burn off that tank.


Here's a link that explains some about it.

how bad is running 87 in an E30 anyhow ? Anyone encounter bad problems on this board ?

no. i run 87 (or something similar) chevron gas. runs like a charm. i never noticed a difference when i ran 92 chevron gas in it. i had to..just to try to lower emissions.
