Does it hurt to switch back and forth with different oils? I ran M1 for 80k miles and have been using Amsoil for the last 30k. I'm going to go back to M1 for convienence reasons and I also want to compare with some analysis. Some on here have said you should stick with one.
How would analysis results be affected from switching to M1 after using S2000?
