Owners of Audi, BMW, Porsche & Mazdas have reported black gloops of wax deposits coming out during oil drains which are not good for drain-pan screens or HLAs. Ash content is 1.2%, higher than any of the PAO/Ester based synthetics (<0.5%) and higher even than plain Castrol GTX at 0.7%.

exactly like I stated above. Talk to any M3, 944, TT owner about this. Syntec might be an excellent dino oil, it's just not a true synthetic.
