Here's the best way to make your topsider AND your Benz last longer;
Clean the topsider thoroughly, seal it in a plastic bag and store it away carefully. Then every 3,000 miles or so, place a drain pan underneath your thoroughly warmed up engine and remove the drain plug. Do this on a Friday night or Saturday night and allow to drain overnight. The next day. Replace the drain plug, the oil filter and fill the engine with premium quality motor oil. Pour the used oil in the jugs that the oil came in and take it to your auto parts store that recycles oil.
This will make your topsider and more importantly, your Benz last virtually forever.
Change oil hot and change oil often,
