The MM finally reached 15% Sunday, so I changed the oil today. It's early for me, I usually wait until the MM gets to 0, but this oil has 10,397 miles on it, the longest I've ever run between oil changes, on any car. I have a hard time with going more than 10,000 miles on oil, especially when that was treatment #1 of Valvoline Restore & Protect. (Who knows how much gunk it cleaned up.) Even though it was an A1 change, I changed the filter too. Normally that waits until Bx shows up.
Nothing changed during this interval except the oil. Previous oil change intervals, where the MM did get to 0, were in the 7-9,000 mile range. So what changed? Only the oil. Prior to this I'd run Honda's 0w-20. What to make of that? Clearly the powertraIn computer noted a change, or maybe it's as simple as a different manufacturer. Other than that, I don't know.
I had to add a quart over that time.
And, I still made a mess with the oil filter though not as much as before. I had cardboard boxes ready, but they were nowhere near where the oil spilled out of the filter this time. Just buy a sheet of cardboard next time. So, spread some kitty litter out and dance a jig on it to grind it in. Once again, Valvomax oil drain for the win. With the engine at operating temperature, it flows out perfectly. Not even a drip.
I still have some leak going on under the flywheel inspection plate, but it is merely seeping now, not a full-on leak like it appeared last time.
