At 800 miles is 69% oil remaining normal? Took to the dealer, they checked the oil and said it was fine - nothing to worry about, check again at 3000 miles. But I am concerned. Any advice is appreciated.
This explains some of what you are seeing. For example, let's just say for the sake of the argument that you let your car idle a lot while not moving, or moving slowly. Then the engine turns over many times while very few miles go on your car. In the most extreme example, let's say you just start your car to listen to it, let it run for hours every day, but never drive it. Eventually you will be to 0% oil life, with no miles driven!yes I do
I have 2050 miles and the oil life is 47%. Have had the car since early October, or about 6 months so, as usual, will change before the year is up. But the GM oil use algorithm is very complex. It apparently takes into account short trips, i.e. were the oil never gets hot and makes that a shorter interval between changes, which it should. If the oil doesn’t get hot it remains diluted from more combustion products (water, unburned hydrocarbons etc.) blow-by when the engine is cold. I live 16 miles from town and purposely try not to drive short distances especially with a Z51 and larger oil capacity dry sump. If you're making a lot of short trips, change it when or before it says!At 800 miles is 69% oil remaining normal?
