Hello All!!

My first post!! I just bought a '92 Caddi Seville - blue mist - 129K. I practically stole this car - got it in great condiiton for half Blue Book!

Im new to Cadillac, gotta admit, but I am very very happy with this car. Its smooth and comfy, even at the milage. Its been maintained by Cadillac for at least the last 60K miles. The owner I just purchased from in fact works for Cadillac. So all in all I was very confident in my purchase. Except for one thing...

She told me when I purchased (yesterday) that it only needs regular gas, and thats what she has put in it. It didnt take long for me to confirm that is completely wrong and the car should have been running premium. So my question is, despite her best intentions, what damage has she done to this car running regular for 60K miles, and even though it seems fine now, what do I need to be on the lookout for? I have refillled the empty 3/4 of the tank with premiuim, and will continue to do so.

Any hints on what I can do to find or anticipate damage is greatly appreciated - I want to prolong the life of my 'new' car as much as possible!!

Thanks!

 

Most likely no damage, however if you have timing checked it's 4+ degrees retarded.
