Stops the wear??? I know Amsoil has been around for a wile, but stops engine wear, really?oldcube said:The service manager at my dealership said not to change over to synthetic until 20,000 miles has been put on the engine. Synthetic may interfere with the normal seating of the rings to cylinders.
I know that Amsoil says it is alright to put in their oil in your engine right away. If Amsoil (and any other synthetic oil) virtually stops the wear on your engine then how can it not interfere with engine break-in?
Last time I had to add a quart at 600 miles is when I got lazy and had Wal Marche' :-[ change oil on my 7.3 F-350. They forgot to tighten the oil filter. :no: Fortunately I had 14 qts still in the pan. I didn't noticed because I was on a road trip. When I came out in the :am from the hotel I noticed my under carriage had a nice coating of rust preventative. Needless to say they will not be working the Qb. 8)KeychainDan said:Yeah, my bet is they have a small leak somewhere.
