Since I can’t source Brad Penn Oil here in Europe without paying absurd amounts for shipping, I’ve been looking for alternatives with a proven high amount of ZDDP.
The closest thing I’ve found so far is Castrol Classic XL 20W-50, which appears to be what Porsche in Stuttgart uses for their completed restorations.
Quote:
Castrol Classic XL 20W-50 is a conventional multigrade engine oil of good all round performance, formulated with high quality mineral oils plus selected additives, ideally suited to older technology and classic car engines.
Castrol Classic XL 20W-50 is designed to meet the motor manufacturers' requirements for passenger cars and motorcycles running under normal service conditions, but excluding those equipped with catalytic converters.
The prime recommendation is for all pre-1980 petrol engined vehicles requiring a high quality product but with an older technology additive formulation.

all according to the
Datasheet.
It may not be ideal but it is better than most of the oils I can get around here.
Does somebody know where I can get a sample of this oil analyzed in Europe? I’ve already bought a few cans of it and plan to use it for my next oil change, it would be nice to know what the actual ZDDP percentage is.
