I wanted to know if anyone has used either Amsoil Synthetic lubricant or Mobil 1 in place of there normal motor oil? I know amsoil is a bit more but, I've heard that it is a better Synthetic oil over mobil 1 and the other motor oils when looking for performance and less engine wear.

What's your take on this battle of the Synthetics?

Good question. Mobil 1 may not even be the first with synthetics but sure put some money into marketing the product. The API (American Petroleum Institute) rates oils and gives them a letter designation. Motor oils say on the container that they meet a certain level of quality for "new car" specifications.

I worked on one car - think a 2001 Lincoln LS that called for a viscosity not found in Synthetics, and I called Mobil 1 - on the container 1-800-ASK-MOBIL and they said to my surprise that they would NOT guarantee their product in that car !!!! I was shocked!

I don't know who to trust with this topic. I can say that a couple cars that I've dealt with, have had Mobil 1 in them when they overheated - one was my own! I was pulling a 7,500 trailer with a 1979 Buick Electra and it didn't like that and wicked overheated. No damage from that overheat - whew! I later needed to take off a valve cover and found no evidence of overheat sludge. I really expected some signs of damage.

As for who has the best I don't know. I'd like to see some other's comments about their experieneces good or bad as it's all good info gathering. Tom
