Back in 1952 my father bought a 1950 Nash Ambasador with 21,000 mile on it. Where he was working at that time had a salesman show up pushing Mobile oil, and telling how great it was and how it cleaned your engine. Dad thought it sounded like a good idea ,so he bought a case of it and changed oil in the Nash. It worked well and cleaned the engine, however the previous owner had used nondetergent oil in it. The engine lasted a week and blew up. Dad tore it down and overhauled it, because that detergent Mobile oil had cleaned all the gunk out. The same hapened to a lot of the companies equipment also. After that, Mobile oil in that location, was known as bearing removal oil and they switched brands of oil. My self i use Castrol oil in my cars and Pennsoil in my deisel tractors. Marv
