It would be useful for someone to post the dimensions of that copper crush washer; it's probably obtainable from various other sources than the dealer. My dealer is 120 miles away, and over a mountain pass... not so convenient to drop in.
Yesterday I had the oil changed at a Pennzoil quick lube place. The guys were intriqued by the car. Having informed myself on this site and others I stayed involved in the process to oversee the work. But first I had to find a filter. The Mitsubishi part number for the smart filter is 1230A040, and the NAPA 7040 is a correct replacement. While this item shows up in the NAPA cataloging system, unfortunately (according to the NAPA store clerk) it's not actually available yet.
Someone here did some cross-referencing and found the Yamaha 5DM-13440-00 is the same filter as the Mitsubishi. So I went up the street to the Yamaha dealer, and about 10 seconds later the $15.95 filter was on the counter. It's tiny, a lot smaller than a Chevy V8 filter for instance. Approx 2" by 2" dia.
So, up the street another few blocks to the quicklube place, where they rinsed the screen on the drain plug while the oil was draining, put in 3.5 qts of 0w40 Mobil 1, and also changed the transaxle lube with 2.5 qts of 75w90 synthetic gear oil. Reused the crush washer. This morning, the exterior of the drain plug is dry, same with the filter, no sign of drips under the car.
I am likely to use the dealer for scheduled service, but this was an early lube change as a sort of mid-break-in thing at 1400 miles that I hope will ensure the best for the internals. Last week I stressed the car somewhat with a fast trip from LA to east of Seattle, including some 4800 rpm 3rd-gear climbs up the mountains and corresponding off-throttle descents on the downslopes. Except for the final 70 miles in WA, I was off the freeways from about the north end of CA. A good vigorous break-in run with varied speeds and loads. The little smart did great...
