I have my old M42 BMW, a 318i.
In the OM, there are no BMW specific specs, merely specs for fairly thick oils under all conditions.
I am wondering whether an A3, with necessarily high HTHS, would be a good choice for such an engine.
For example, both Valoline Durablend and Maxlife 10W-40 claim to meet the A3 spec, as does GC.
Is A3 the magic spec for an older European car that predates any manufacturer's specs?
I am currently using Castrol Tection Extra 15W-40, a pretty thick oil, and would like to try something thinner.
I am thinking that A3 is an appropriate spec to look for in an oil for this car, as well as many others.
I would like to hear what those more knowledgeable than I think.
