Have 2 vehicles...... '09 base vette and a Suburban. Guess I had a brain fart and thought I was filling up the other vehicle. Is there an octane boost that I can add to make up the for the low octane gas I put in?

I looked on Walmart web site and saw 3 different ones. I'll bet any auto part store will have it.

Your car won't melt on one tank of 87. Burn it up and be done with it.

I'd rather live with one tank of low octane fuel, than dump in a chemical additive that may do more harm than good.

and it would take 5 or 6 bottles of the off the shelf boosters to raise the octane from 87 to 89.

If the OBD detects any knock, the PCM will pull out timing...so it will be ok, you just might loose some performance.

The car will run on the low octane. Your performance will be less till you get a full tank of 93 in the car. How empty was the car when you filled it up, if it wasn't empty and was around a 1/2 tank it probably wont affect it very much

Don't worry about it.

Just drive it and burn it. I'd just stay away from full throttle accelerations. It's designed to be able to burn 87 octane.

:agree:....

Car was on empty when I filled up so I now have a full tank of 87.

drive off half a tank and fill up with highest octane you can get, then next full refill put the higher octane in it.

87SAM

That's still fine. As mentioned, the manual states that 87 can be used, just a possible decrease in performance. The weather is cooler now, that helps even more. Just think of the money you saved with the cheaper gas

Oops - better sell it fast, lol.

Under anything less than hard acceleration, you wont be able to tell the difference!

Jim2003

Under normal driving conditions you will not experience any true different. If it is extremely hot or you are pushing the go pedal really hard, then maybe some issues. When you get down to 1/2 a tank fill it up. You will be fine. The computer adjusts

Dano523

You will be fine.

The OEM tune has a low octane fuel table in it to use when the octane level in the fuel are less than ideal, and when the car uses this table, will just pull timing; ending up with worse gas mileage and less HP.

Also, if you stomp on the gas, the engine has a knock sensor, and will just pull timing even more to prevent problems as well.


So on that note with it being winter and all (E10 fuel pretty causing the same as the above, even with it rated 93 or above), just burn up the fuel in the tanks and go on with a normal life.

This ! Heck, around town and I live just south of you, I run mid range all the time without issue.

TxLefty

Weather is nice and cold anyway. Timing couldn't have been better.
