I, also, use synthetic Amsoil in a number of vehicles, but only in older
engines if they have been rebuilt and have close tolerances and lack carbon
build ups. Though our 1967 Amphicar only had 12,000 miles on it, it was
rebuilt by the previous owner 20 years ago. Until recently we drove a
gorgeous turquoise and white 56 Olds Holiday Coupe with a continental which looked
like new and used it in that. We also have a 1948 Ford Woodie wagon and a
60 Buick convertible and use it in them too as they are more our "road
cars" which we take on trips or more distant shows . I recently acquired a case
of the new Zinc added Amsoil to reduce wear on the tappets, according to
my reading. However some of my cars don't get used enough that this would
probably matter. Anyway, my own experience with Amsoil has been fine just to
add a Yea vote.

No problem with Amsoil, it's great stuff. The grease and transmission lube
works super well on Amphicars and it's what I use here for more than 10
years (although it costs me twice as much as I have to import it from the
States).



Amsoil 20W/50 would work well in the engine but in my opinion is unnecessary
as you need to change the oil every year anyway (so loose the long life
benefit) and the Amphicar engine isn't stressed at all in standard form so
doesn't need the extra lube performance.



Thing to watch is most people use synthetics in newer cars where the oil
spec can be as thin as 0w/30. That's what I use in my modern turbo Volvo but
I wouldn't ever put it in Amphicar, oils than thin didn't exist when Triumph
designed the engine. Even a rebuilt engine will only be to original
tolerances and that really needs 20w/50 or at a push 15w/40

I've considered synthetic off and on several times as I've changed cars in my collection. In many ways, the discussion is like incandescent versus flourescent lighting and which uses less electricty (left on or off). I really didn't pay attention to the rise in synthetics until Mobile 1 was required for use in my wife's (then new) 1992 Corvette. I then changed to synthetic for my car collection for about the 10 years following... I found that oil usage increased in all my old cars, needing more refills than they did using traditional oil. I also saw in subsequent purchases of new Corvettes (requiring synthetic) that they'd quickly burn off the first quart of synthetic but then remain stable thereafter. None of my cars were subject to high mileage so the engines themselves weren't being "worn-out." I finally decided that high-grade non-synthetic was best for my old cars designed for traditional oil and only those calling for synthetic at manufacture was they way to go. Splash! ya' got the "eye," man... my first car was a '55 Olds and the deep radio bass speaker and huge back seat were invaluabvle factors in my adolescent development! lolol... - azpaul50

NOT ANOTHER "what oil thread". See below as posted here previously and stolen from another forum ...

============================================
OK, here is the skinny..again

There are several types of sythetic the base stock is what differentates them.

The best base stock is Polyol-ester (Redline & Motul)

Next best Di-ester (Royal Purple, Amsoil, Neo)

Next is polyolefin polyamine (Mobil 1)

Hydrocracked (Syntec, Valvoline)

Finally regular dyno oils

In terms of a daily driver, just pick the synthetic you like the sound of and change it every 5k...it ain't gonna make a hill of beans difference over the life of a street driven motor!! Your Amphicar essentially has a tractor engine, it is not built to anywhere near the tolerannces of a V-tec.

BTW, the racing industry DOES NOT use the same Mobil 1 you buy off the shelf, true racing oils do not contain detergents. A racing engine is typically rebuilt long before any issues with deposit build up occur. Also, racing oils are usually not multigrades, they are straight weight oils....

blah blah blah blah blah.....do a search

If they were the same price, I'd buy Motul / Redline every time and twice on Sunday

Yes Mike, comments like that are why not much is posted on your forum any
more !



A lot of Amphicar people have gone back to sharing info between friends with
Email, it avoids the hostility although also means those new to the Amphicar
world miss out.



Irony is none of us discussing this particular and important oil topic live
in the USA so the comments below listing USA market products are, frankly,
total Bollocks.



Thank you and goodnight.
