OK, my turn. I started using Mobil 1 when it first came out, and I think that was around 1970 or perhaps just before. At the time they showed engines run to high miles with standard specs, and said it was good for 25,000 miles use between changes. Sometime after that, perhaps realizing that they wouldn't sell much product at those intervals, they dropped the mileage claim. I've used it in lawn mowers, trucks, cars, and vans. I always let the rings set in a new engine and around 3-5,000 change out and then change the filter every 6-8 thousand and the oil at 20,000. Once I had to get into a 1977 VW Rabbit engine to replace valve stem seals, but that was at 240,000 miles. Cars ALWAYS wear out before the engine begins to wear. I've never owned a vehicle wholse engine used oil. I bought a new Kubota lawn mower in 1988 and ran Mobil 1 in it. The mower saw 1.5 acres every week (my personal exercise program) and the oil was unchanged and still clear the week before it was stolen in 1998. Wish I had that mower back. Much better than the Honda which replaced it.
