So I take my '99 Taurus in to the local Ford dealer to have the coil spring shield recall performed. I get a call a few hours later saying the work is done, but the tech who was working on the car says the oil is really dirty and highly recommends an oil change (Mobil 1 5w/30 has been in only 4300 miles). And oh by the way, the fuel filter looks like it hasn't been changed in awhile also so we should replace that too (replaced 28,000 miles ago). I decline both service suggestions and say I'll be in to get the car in a bit. When I get there service writer/ advisor/ whatever still insists the oil should be changed, and then also states it's also a quart low. I politely say no thanks, I'll do it later. I get home, let the engine cool an hour, check the dipstick, oil level between add and full, yeah the oil isn't new out of the bottle golden but it isn't crude oil black. I guess Ford recommends oil changes based on visual analysis now... Last Blackstone report with 6700 miles on oil still showed TBN of 2.9.
