What if we can something that's totally odd compared to a "normal" motor oil and mix with a "normal" motor oil? I'm talking about a blend of something like the version of Fuchs that has little to no ZDDP. Obviously, it's AW package is significantly different from just about anything else out there; or, alternatively, they just decided to go cheap on the ZDDP, which I doubt.
Obviously, additive clash would be a misnomer, but I'd be extremely reluctant to mix that Fuchs with something else.
As you know I'm familiar with the Fuchs Titan GTL XTL 0W-20, an ester based Zn and VII free long drain racing oil and I still have some in my stash. This is Fuchs flag ship product and they certainly haven't "gone cheap" on the AW additives they're using. Probably because of it's unique chemistry, Fuchs makes a particularly point of emphasizing that it is fully compatibly with all other mineral and synthetic oils. But it's only offered in one grade so I can't see any blending options with this oil.
Certain oils are prime candidates for blending purposes because of some exceptional attributes but I agree that this Fuchs oil I would want to run straight to get the maximum benefit out of it's unique chemistry, why else use it.
