How often have you been advised against tipping synthetic oil into the engine of your classic car? Especially in old (re) used engines that is a very unwise choice. The machine will leak and consume much of that much too expensive oil.
Synthetic motor oil only seems to be suitable for modern engines whose tolerances are much, much tighter. Great was the surprise when Amsoil came with the message that it could supply a 100 percent synthetic motor oil for classic transport! The Amsoil Synthetic Premium Protection - according to the supplier does not affect the gasket material and seals of old (er) engines, but provides a durable seal, maximizes the efficiency and durability of the engine. The oil is available in 10W-40 and 20W-50. Available through the Dutch sales channel LowVeld BV in De Meern in Utrecht. Who dares?
