Interesting that they did mention filter changes. I don’t know what ‘sealed up’ means either...do they literally not have a pan on the vehicle?
I’ve noticed my newer vehicles have a magnet in the pan...usually covered with small bits of metal. I wipe the shavings off the magnet, change the filter, add back the amount of fluid lost when I dropped the pan, make the sign of the cross, and go on with life. I figure changing the filter often enough will change out enough fluid over time.
I think the lesson learned here is that the quick-lube places usually use very low quality fluids....they added an additive to make it AT-4? If that worked, you’d be able to buy the same additive off the shelf.
Many of my newer cars require fairly specialized oils...semisynthetics, in some strange weights, like 5-20. I would be terrified to go to a quick-lube place, since that magic hose that dispenses the oil is probably just 10-30.
If you have a newer car, I think the options are increasingly becoming DIY or dealer...but I do have little trust for the independent lube places.
Same here. At no particular milage, just when the fluid gets nasty.
