I live in south jersey and the gas stations in Jersey is full service. I ask them to fill my car up with 93, and I later found out that they put 87 in tank, completely filled up. Would this damage my car.

 

Just dont race it or push it hard and you should be ok..

 

Yeah, I remember a post on here where the exact same thing happened to another forum member. Try doing a search to see if you can find that post. I would try syphoning some of that gas out (maybe half of it at least) and filling up the other half with 93. I remember that some 87 wouldn't hurt it, as long as you mixed it with 91/93, but I wouldn't drive around with a full tank of 87 in your Z.

 

ECU will adjust your timing and you might get some knock. Just drive a little more careful and make sure you have 93 in there next fill up. Maybe add some octain booster??

 

It won't hurt it. You should be fine. Your performance will suffer though. Start adding 93 octane to the tank when you burn off some of that 87. BTW, how did you realize it was 87 octane?

 

damn i am from jersey too and that happened to me also! you should go out when they fill your car up and make sure they put 93 in there.

 

You'll be fine. Just don't push it hard until your next tank.

 

You guys should stensil "93" on the gas cap in white. Just a thought.
