Ian,
Years ago I bought into selling AmsOil because it would give me a tax
advantage. That said here are some of the answers to your questions.
>From what I was told back then, when Mobile 1 was really just getting started,
Mobile 1 is a paraffin based lubricant and does not have all of the coating and
clinging properties and the cleaning qualities of AmsOil 100% synthetic
lubricant.
That cleaning quality is something you should pay close attention to. If your
engine is in good mechanical condition and does not have a layer of varnish
holding the valves and who knows what else together you are safe to give it a
try. If not AmsOil will clean EVERY bit of dirt out of your engine. Right down
and into the ring lands. That is why an engine with 350,000 miles looks like it
is almost new, both clean and wear. I bet the babbit is still on the bearings.
That is why he re-used them. I won't make any claims for what it will, or will
not, do for U20 timing chains, but that stuff is really good in engines, rear
ends, and likely steering gears when used properly.
Some of the people who commented on my question about using AmsOil gear lube may
have a good point about using it in the tranny. I will defer to their
experience there, but my own experience with a noticeable mileage in a 69 Chevy
396 pickup that I put AmsOil gear lube in the differential is good enough for
me.
I am trying to decide if I want to risk Amsoil in my 2000 engine when I get it
running in the next week or so.
If you use AmsOil, use their oil filters too, or look for Hastings oil filters.
Hastings used to make AmsOil filters and they are made of virgin wool, not
paper. The filtration is down to around 4 microns compared to 24 microns for
paper filters.
By the way it is cheaper to become a dealer and buy the lubricants, filters and
air cleaners rather than just buy them outright.
Enough advertising (and I am not a dealer)
