0w/10w/20w, 40/50/60. Mineral, semi, fully. Mobil, Castro, Shell, Valvoline, Millers, Porsche Classic...
Plenty of threads on this but it also seems opinion changes, and Porsche have their own branded line out (made by someone else, not them) so their opinion on what's best for the 993 must have changed.
Thin stuff makes the engine leak (apparently?). Nano particles reduce wear on older engines? And so on.
Who is using what?
Also interested in how much people use between annual services. I've read different views on this ranging between absolutely nothing to a litre every 600 miles being normal.
