With all due respect ****, as I know you have been involved with oils a lot longer than me, I don't think you're giving the semi synthetics a fair shake. You have seen how well Schaeffer's blends perform, so why do you doubt that Amsoil's blend would too? It might just be a great 10,000 mile oil, and that savings per quart is pretty substantial if you ask me. Especially for Buster whose engine uses a bit of oil.
****, I felt the same way, usually the full syn will be a better choice, but under certain circumstances the blend might prove to be a better choice.
Buster, you picked two interesting oils. Mobil's 0W-40 looks noticeably thicker than their 0W-30 does. It actually looks almost like their 5W-30 and OW-40 are pretty close in terms of cold weather performance, so the 0W designation is kinda misleading. On the Amsoil side, it looks like the 10W-40 flows extremely well when cold. I would bet that it could meet the criteria to be classed as 0W weight oil as well. I think it's also agreed that Amsoil doesn't tend to shear down like Mobil 1 seems to do.quote:

I appreciate all the advice and think a 40wt. is the way to go. I wanted to know what people generally think of M1 0w-40? It seems to be getting mixed reviews. I was reading some of the analysis and it appears to thin out. This would defeat my purpose of using this particular weight, although I am considering it. I know some don't like it and some do. Being it is a 0w, do you think it would be better for me to stick with Amsoil's 10w-40 synthetic? This would probably hold it's weight better over the long run althoug the M1 is the long drain euro formula which should be able to handle it. I bring this up bc like I said before, I generally don't go over 10K miles before draining the oil so I don't want to be wastefull. Going over 10k doesn't sit well with me.
