I put Mobil 1 in my 560SL at 100K miles. I now have 131K miles, no problem. But I am the type of person who belives that if dirt is the only thing sealing my engine, I would have no problem putting in an oil that would disloge that dirt, casue a leak at which time I would fix the leak. So therefore I would never think twice about putting Mobil 1 in any car as long as it doesnt burn espensive oil.
