I accidently put unleaded in the 1990 cadillac seville that I bought an hour ago and the car jolted as I drove home, I later found out from previous owner that I needed to only put premium. Now what do I do?
have the same problem?

The standard unleaded will not be a problem, just fill with premium and if a problem persists get a scan done to check for any unresolved fault codes.
