First Oil Change

I've got about 500 miles on my '05 GTO. How many miles should I go before having the car serviced?

I seemed to have better performence right after the first oil change. Engine seems to start alot easier, maybe they had real thick oil in it for break-in. Just over 2000 miles now and it feels better than when I first got it.

Had my first oil change today at 758 miles. Mobil 1 5W-30. The assembly-lube-mixture that comes in the car smells "stronger" than regular oil.

Had the dealer put in a magnetic drain plug while they were at it - about 3 bucks for the plug. They were out of "Mobil 1 only" oil filler caps but I have one on order according to the paperwork.

Changed my oil+filter @ 1700 MI. Still looked fine. The Dealer recommended 3000 miles but I did not want to wait that long. Damn that front oil pan protecter is heavy.

Did anyone read the owners manual. These cars have a oil management system that measures engine temp and revolutions to measure oil use. Your car tells when to change the oil and depending on how you drive you might not have to change it for up to a year.

Oil change interval threads are always a good read. Everyone has a different opinion, and there is probably no one right answer.

I personally think changing the oil for the first time at 500-1000 miles is a good idea to get rid of any initial break in residue. I changed mine at 800 miles on my 02 Z06.

After that, there are no shortage of opinions. I used to be a 3000 mile/3 month oil change guy, but have changed my tune in the last year or so. I now run my wife's Chevy Trailblazer per her oil life computer using AMSOIL XL-7500 Synthetic 5w30. Just changed her oil this weekend. She got six months and 6500 miles on this oil change. On my F350, I use six month or 15k mile intervals using Series 3000 Synthetic 5w30 Heavy Duty Diesel Oil.

If you are using your car as most people do for daily driving, I would feel comfortable using the oil life monitor (or one year whichever is shorter) if you have a good synthetic in it such as AMSOIL or Mobil 1.

Here are a couple of interesting reads on oil change intervals from Lubes and Greases. These are a little dated as they were written prior to the newly released line of extended drain interval oils from Mobil.
