Took Freya to the local indy import shop for an oil change. Turns out after all they did not order the Mann filter and did not have the correct oil on hand. Since I had both because I originally intended to do the oil change myself, I brought the oil and filter to them. They've worked on SLKs and Crossfires before mine came along.
They pump the old oil out, put the new oil in, and I'm hoping I don't see the HI light come on when I pick her up.
Mileage is just under 30,000. Bought her at 17,787, she had fresh oil in her, and it was suggested to do this oil change now, about 30K miles.
Freya's been running fine. No codes, no hiccups ... driver side window is about an 1/8 of an inch low, and this causes some wind noise when the top's up, but I'm not eager to open up the door panel to adjust it. Water doesn't leak at all, and I use noise-dampening ear plugs to take the edge of road noise. They are very helpful with wind and road noise when the top's down, too.
We'll take a little drive when we pick her up from the shop to see if we notice any difference.
Our neighbor from hell has been on a rampage the past couple of months, so I'm avoiding her weirdness by not working on the car in the carport right now.
UPDATE: While they had the car they checked hoses, fluids, brakes (10 mm and 8 mm, front and rear, wearing evenly), found no codes, cleared the oil service code, put the tire pressures at 32 front and 33 rear and noted the TPMS light was on. It turned off about a block from home, typical, no worries. Belts and hoses and wiper blades all fine. All this for ... $53.
Cheaper than any quick-change place. More thorough than any quick change place.
