How bad is it?? I just got back from running errands with my wife and I let her drive while I rode shotgun. We went to fill up at the pump and she decided to fill it up while I sat in the car. She began fueling and something told me to make sure everything was good. I stepped out the car and seen 15 bucks already pumped. almost 3 gallons, of 87 octane!! How bad is this going to be?

 

your car is going to explode...

you'll be fine. it's not going to kill you or the car. the manual specifically says it's okay to fill up on low octance - if high octane is not available. keep in mind it also says to fill back up with high octane asap.

 

thanks... car blew up

 

Is your car boosted?..

If not.. you should be ok.. Just fill the rest of the car with alot of 93/94

 

you'll be absolutely fine, assuming no major mods.

 

Wish we had anything above 91 out here.

 

^ When I was in Toronto, the tuner told me to bring octane booster.. and throw it in the car just in case lol. I did so just for safety.. MAAAN Did I feel bad *** putting that stuff in my car.. I even got the NAWS ones!

 

I need to see a picture of said wife before making any type of recommendation

 

You should be okay with a bit of 87. It's when you use full throttle and/or the weather is hot that the ECU will likely back down on the timing, so your gas mileage may suffer as will your performance. The only way to tell is to hook up to a scanner and see your timing in real-time.

The other issue is when your car gets older, and pre-ignition becomes a more prevalent problem. If the knock sensors don't work at optimum, you can cause potential problems and damage your engine.

 

did anyone notice he said "$15", "almost 3 gallons"?!!... 87 is more than $5 per gallon in WA???!!!

 

^hmmmmm didnt even notice haha good eye

 

Your motor is toast from the low octane gas. Send it to me and I will send you mine (see my disappearing oil post).

 

throw in some octane booster

 

if thats true, i thought we were bad over here in CALI at 3.50$!

 

87 is was 3.14 in Tacoma. damnit. im dumb. that's about 5 gallons then. im dumb
