Yeah, I know, its an Aluminum engine! But there are lots of ferrous metal parts inside the engine and transmission. I checked the engine oil at 2500 miles, and it looked dark and dirty (for 100% Synth oil). I decided that it was time to change it from the original "break-in oil" to a clean oil. At the same time, I happened across Magnetic oil drain plugs and decided I would install them in the engine sump, transmission drain and fill plugs and the newest "black Hole" magnet sysrtem for the outside of the oil filter
I feel that the dealers and MB have only our interest in mind for 24,000 miles. After that we are all fair game for the dealers. So, I feel I am going to do my best to preserve the engine and transmission to the best of my ability.
I had all of the "Dimple" magnetic plugs installed, (they can be found at 451series.com), filled the engine with Amsoil 5W-30, and the transmission with Mobil 1 75W-90 Gear Lube.
It may be my imagination, but the new oil seems to give me just a little more pick-up, but I really don't know. Anyone else find anything similar?
