Messed up with gas

kidkotic2001 · 10-03-2015, 03:50 PM

So I accidentally added 4 gallons of 85 octane then notice and stopped finishes with 91 octane. Is that okay any damage to car? Should I drain has or anything

You'll be fine.

Just drive normal until your at half a tank and refill with 91.

And by normal Trips means no WOT and keep the rpms low.

85 octane gas or e85?

Add some octane booster and forget about it.

Octane booster doesn't help much. It will only raise the octane a few points. Either drive carefully for half a tank and top off with premium, or throw some Toluene in. That'll raise the octane. Just don't get any on your paint.

You WILL notice a big performance dropoff. All you can do is ride it out until next refill. Low octane won't hurt the car but the engine will let you know you're not going anywhere fast.

Octane booster will only boost like 0.2 octane for the entire tank, no?

Pour in toulene like you mean it if you want.

Actually, put in some E85 which will effectively raise the octane rating; 2-4 gallons would do nicely.

Is El Paso TX a high elevation area? I'm surprised they're selling 85 octane if it's near sea level.

jwick · 10-04-2015, 12:45 AM

I've actually never heard of 85 octane

chuckie311 · 10-04-2015, 01:23 AM

Haha come to Colorado, that's all we use for the cheap stuff. 87, 91, 100 and E-85 are available. Wish we got 93 octane.
