Benford:
Thanks for keeping us posted. I've got a 2000CE that I bought new that now has 205,000 miles. Mine also burns lots of oil.
I tried 10-30 this summer and it didn't really make any difference that I could see. I changed the oil last week and noticed that I had went almost 10,000 miles since the last change. But since I put in probably over 5 gallons of 10-30 oil in that period of time (10,000miles/500 per quart), I'm not too worried.
My check engine light comes on and goes off on a weekly basis now. Its always the Cat efficiency code. I drive highway all week, which increases oil consumption. So usually by thursday, the light comes on. I fix that by several in-town errands on weekends, which don't use as much oil. I learned here, I think, that the ECM looks at 5 cycles to decide whether the Cat convertor is working efficiently, and then trips or clears the light. Last weekend, I made several start/stop trips Xmas shopping with car warm. Sure enough, light went off on sunday, then came on today (friday). Need to run some short errands this weekend to fix it again. ;-)
We don't have emission testing in my area, so I live with it. I buy oil by the gallon or five quart bottle. I gave up on the really good stuff, it just isn't in the engine long enough to matter. I do spring for good filters though.
Other than the oil issue, its been the most reliable car I've ever owned. I plan on keeping it as long as possible. I live in North Alabama, so it has no rust at all.
Only parts I've replaced (other than wear items) are the catalytic converter and O2 sensor 18 months ago, and two weeks ago, the left front caliper. It was dragging, so they put a new one on as part of a front brake job. I smelled something hot and almost burned my hand on the left front tire rim.
