For my 4th service, JLR dealer put 8 quarts of oil in. I drove a hundred miles before checking it(I was either to quick or to slow to read the level). Dash showed overfill. I immediately called the dealer. They took me right in and removed 0.75 quarts of oil. I’ve heard of them overfilling AWD cars because they take only 6 quart whereas my 6 takes 7.25 quarts. I guess they can screw up any car. All documented so if there is any engine problem, I have it in writing.
