...and you wouldn't believe what came out.
I put 6 - 8 ounces of Seafoam into the crankcase and drove about 25 miles total, running the engine on my lunch break and letting it sit all afternoon then driving it home from work, and finally draining the oil. My oil catch pan was full of ... junk. The best way I can describe it is: have you ever seen the stuff that settles in the gutters on your house after the shingles have been weathered for a few years? That nasty, black, pasty, sand-papery looking junk that settles in your gutters? Well that's what this junk looked like that came from my engine.
This stuff works!
I've been using Shell Rotella T6, and changing every 5,000 miles with a new Purolator Pure One filter. This time I went 7,000 miles. Before I bought the Jeep, it was a Chrysler 48 month lease, so my assumption is that it was serviced at a Chrysler dealership on a somewhat regular basis. I think that I'm going to stick to no longer than 6,000 miles between changes now, and use the Seafoam every few months.
I also put a half-can of Seafoam into my fuel tank. We'll see if it frees up any power in the fuel system...or perhaps it'll clog the system by cleaning things too well. Who knows.
