Volkswagen Air Cooled Engine Oil

[Cornershop]

I've read Amsoil AMO 10w40 has been around for some time, but it appears to be ideal for aircooled engines?

Any downsides to this oil?

Agreed, not the cheapest place - cheaper per gallon from Germany to the UK

Also it's full synthetic, i have never seen an aircooled VW that doesn't leak! FS might aggravate it.

They won't be "0%-SAPS" though, as the mineral base oil will contain sulphur.


What temperature would you need to "flash off" all the oil, leaving the ash ?

Well, that's a point of semantics. In reality the oil will combust with the fuel and leave behind any ashy deposits; a simple distillation will not create any ash (as you know!).

It doesn't help that people talk about ash content of an oil, which is wrong. It is ash propensity, because you need the combustion (oxidation) to form the ash from the metallic elements in the additives (stating this for all interested readers, not aimed specifically at Shannow).

Any major 10w40 will do it.
