To Be Different
Brothers of The Benz
What I am going to reply will bring more flak than has ever been.
My 1987 300E with 175,500 miles has had the oil pan and filter changed once at 25,000 miles.
As a long long user of the electric powered top sider oil pump and changing engine oil at 3500-4000 miles for the life of my Benz, I also pump out the transmission oil sump of 3-3 1/2 quarts of fluid. No, this isn't a complete change just 3 quarts of fresh fluid every time I cange the engine oil.
My transmission performs excellently and has no leaks with the exception of a side band strut plug that was a simple repair.
At the same time that I change the engine oil and suck the sump, I suck the power steering reseviuor empty, removing the filter to get to the bottom. I refill using Synthetic Power steering fluid.
So you see there are other uses of Top Siding".
