A couple of years ago, GermanAutohaus published a VOA of Motul Classic 20W-50
. In the US, this is the only oil sold by Motul for classic vehicles, and it is marketed as suitable for engines 2001 and older.
However, in Europe, the Motul Classic catalog
has quite a few references formulated for various eras of the automobile history:
- SAE 30 with low detergent level (pre-1950)
- SAE 50 with low detergent level (pre-1950)
- 20W-50 with mid detergent level (1950-1970)
- 15W-50 with modern detergent level (post-1970)
A close look at the technical data sheet reveals that the Euro version Classic 20W-50 is not identical to the US version Classic 20W-50 (see comparison table below).
However, I was more interested in the Classic 15W-50, and especially how it compares with the 4100 15W-50, another semi-synthetic oil with modern detergent levels.
A few VOAs have already been published for this Motul 4100 15W-50, including:
- GermanAutohaus (May 2016)
(scroll to the bottom)
- SubieRubyRoo (January 2019)
- Bustaknuckle (January 2020)
I just received my Blackstone VOA of the Classic 15W-50, posted below along with the manufacturer's technical datasheet. I've also attached two comparison tables of Motul Classic products.
To me, it looks like this Euro Classic 15W-50 is very similar to the US 4100 15W-50, with a higher TBN, but quite different than the US Classic 20W-50 (see molybdenum & boron).
