As a matter of interest our 2007 Suzuki Jimny Jeep was run on Magnatec most of its life from the dealer service and later by myself.
At 50,000 miles the sump suffered from corrosion from the outside due to the use of salt on the winter roads.
I had in 1993 to change the sump on my 36,000 mile Golf GTI for that same reason and it was serviced in accordance with the service schedule and the sump inner surface and all the internals of the engine had about a 6 mm black sludge covering.
On changing the Jimny sump in late 2013 both the internal surface of the sump and the engine components has a thin film of clean oil cover no slugde at all evident.
The only problem I have with Magnatec is it comes in 4 litre tubs which are great for lots of cars but just a bit tight for mid sized cars. In my case with a fleet not a problem but for those running only one car it can mean having to buy an expensive 1 litre tub to do an oil change.
Great stuff in my book.
