Re: Black Gold-Texas Tea?
Once the oil change interval is extended beyond generally accepted good practice (3000 mi.?) there is still a lot of sludge and dirty oil remaining in the engine and pan after the nasty oil is drained. It may take several oil and filter changes to get all of the dirty oil out of the engine. Just before changing the oil and filter (100, 200 miles or so), add a pint or so of Diesel fuel to the crankcase. The Diesel fuel will help clean the engine with no damage to the engine, just don't leave it in too long.
