I bought my GTO in July 2004 and currently only has 3800 miles on it. I changed the oil last fall with 1700 miles and recently with 3600 miles, I use Mobil 1 synthetic. I think changing the oil & filter only once a year is ok, do you agree?big_mike said:Thats quite ok, there are plenty of us on here who are and are more than happy to help you.
I would recommend if you dont drive that much and the car spends some time sitting, by all means change it every 3 months or 3000 miles. BUT, if you drive it daily and put a lot of highway miles on it, you can very easily run up to 10,000 miles and have no problems.
Some users complain about their cars burning oil so keep an eye on that too!
any other questions, dont ever be afraid to ask.
I understand what you’re saying, but when I change the oil, there is absolutely no water in the drain pan. If there was, it would be sitting on top of the oil, wouldn't you agree?big_mike said:the problem with doing it only once a year is condensation forms inside your oil pan and water and engines dont mix. Since yours sits most of the time I HIGHLY recommend changing it every 3-6 months to ensure no condensation forms and gets circulated.
I thought oil was heavier than water???big_mike said:oil is lighter than water, no, it would be on the bottom and you wouldnt see it come out but over time, it would wreak havoc on the motor.
Good point.big_mike said:if it was, then it wouldnt sit on top of the ocean when there is an oil spill.![]()
