Check out this post I found on one of the LS1 boards:
For the past 30 years or so I have changed oil in the cars/trucks/boats/mowers etc. that I have owned VERY frequently. For the LS1 - SS Camaro every two months I change the oil twice. This involves the first change with cheap dino oil and a new filter. The car is run for about 10 minutes and then a second oil change is done. FOr the second change, I use fully synthetic oil and a new filter. In two months of driving I usually cover about 1,500 miles or so... I have never had any major engine problems, blue smoke, bad valves, noisy valve-trains etc. One Honda I owned went 240K with no problems... So my question is this - I'm I a compulsive oil changer or I'm I justified in changing so much?
