2015 GLA 45 185.5k Service

Changed engine oil / filter
Changed air filter
Changed cabin air filter. Need to order a replacement cabin filter cover as one tab is broken. Should combine it with the next order pickup so I don't have to pay shipping.

Considered changing brake pads and rotors (I have all new Brembos in boxes). Decided it has at least another 10k on existing pads

Discovered that the flex joint in the intermediate pipe between the cat and the rest of the system was completely failed and dumping exhaust on the engine oil pan. Replaced with a $40 Walker unit. https://shop.advanceautoparts.com/p/wal ... haust+flex

Not bad. What have you need getting for fuel economy? You might be the first to clear 200k.

I think in the 27-29 mpg range. I haven't checked in a while. The computer keeps reporting 28-30, occasionally 32 but I think it's a few percent optimistic.

City and cold starts seem to hurt it less than I would expect. I don't think I've seen less than like 24 mpg or so reported on the computer even if I just drive in-town.

I also forgot that pulled and rotated tires.

I googled - there's a guy on here at 370k km (230k mi).
