ok to start I have a 95 3.4L firebird I bought 2.5 years ago with 58K on the clock. it was using regular but I switched it to amsoil a few months after I got it. sinve then I have been pretty regular with the changes, every 12K like it says on the bottle and every 2 changes for the filter. well I had been having problems with it for the last 6 months(not engine related) so I had not been able to drive it much so I never thought about changing the oil when I did. I finally changed it at 107K 2 weeks ago. it had 17K on the oil and I didn't change the filter the time before that so that had like 29K on it.
there were no shavings in the oil or anythign like that but I am wondering if there is anythign I should be looking for for the next few weeks? when I change the oil again is should I use something like seafoam to make sure I get everything cleaned real good? or should I do it now and change it in 500 miles? any help is much apreciated
