I finished my Auto-RX treatment on my 98 Chevy ext-cab Z71 with the 5.7L yesterday. I Used 10W-30 Mobil drive clean and an AC-Delco PF52 filter during the treatment and drove 800 miles.
I cut open the filter today and did not find any dirt or sludge, just a few small clumps of the Auto-RX as it appears before it is room temperature between a couple of the cleats of the filter. It was a light brown color and had the little granules in it that Frank talked about in the past. You could see alot of the granules left in the filter body which also didn't have any dirt or sludge in it.
I don't know if my engine was just really clean for using Mobil 1 for the last 35,000 miles on a 3,000 mile oil change schedule or if I didn't run the treatment long enough. The engine only has 49,300 miles on it so that may have something to do with it also.
At least now I'm pretty confident that the inside of my engine is clean. I installed 10W-30 Mobil 1 and an AC-Delco UPF52 filter and added a maintenence dose of 3 oz of Auto-RX. I haven't decided if I'm going to run this oil change 3,000 or 5,000 miles and see how well things are holding up. This will be my first analysis running the 10W-30 Mobil 1.
Any thoughts or comments?
