Put 87 in her on accident

[Twista]

Supposedly the timing is bumped up on my car. I was told the previous owner put the highest octane he could get @ the gas station.

Since i brought it i started using 93... than 91 and now 89 for the past month with no problem.

I put 87 in her lastnight on a pretty much empty tank and the car runs fine. WOT is fine and no backfiring or popping. Im now pretty much empty again so i ran through the 87 with no problem.


Is it safe to use 87 in her? She still drives the same

Thanks

If its not pinging then its fine. Usually w/ advanced timing you have to run a higher octane. Id put a timing light to it to see where its actually set

If it's not pinging, then I wouldn't worry about it. +1 on checking the timing.
