Yea except the V2 doesnt even have a magnetic drain plug , i verified this through the dealer. Thats why I had them put on a "filtermag" even before i left the dealer with '4' miles on the new girlConsidering how fuzzy the drain plug on my 07 vette was at the first oil change (5,000 miles), there's no way I'm waiting that long on the CTS-V. I've got 1,100 miles on the CTS-V and the next oil change is scheduled for the first available weekend.
Oil life monitor was at 77% and while I drove it at WOT at times, it was always on the highway cruising at 65-70 and then up to 100+ speeds.hey aero what was your oil monitor % at the time you had your first oil change ? and how were your driving habits ?
i have about 650 right now with 89% oil life. Mostly 40-60mph street driving. Not babied too much either. I want to cut the oil filter to see how many metallic particles the filter mag held but not if it means running the car w/out it.Oil life monitor was at 77% and while I drove it at WOT at times, it was always on the highway cruising at 65-70 and then up to 100+ speeds.
I wasn't really hard on the car when I first got it, but I didn't baby it either. I hope that makes sense.
When I had a Chevy Silverado Duramax and I changed the oil, the oil was instantly black right after putting clean oil in it. Diesel engines are extremely dirty running.Some of you have mentioned that the oil gets black fast. I know with the diesel vehicles I have owned that the engine oil turns black very quickly, due to the very high compression and cylinder pressures and the blow-by that causes. But diesel oils are somehow built to absorb the contaminates, and the oil change intervals can be as long or longer than a gas engine even though the oil looks like black tar. Diesel engine techs say the oil itself is still good even though it looks bad.
If the LSA has similar high cylinder pressures causing cylinder blow-by, blackening the oil, but the oil itself remains intact and able to provide protection then the oil change interval suggested by the onboard computer might be correct. I agree that changing the oil early can do no harm, and might do some good. I just wish there was a positive correct answer as to when to first change the oil.
