I'll be coming up on my first 1000 miles soon. With every other new vehicle I have bought, I change the oil at 1000.
As a machinist in my early years, I am very much aware of various machined parts, machined castings, etc and the burrs that would tend to make their way into the oil.
I believe I will ask the dealer to change the filter and add back the 1.5 qts at 1000 miles. In that past, dealers seem to think I'm crazy, and this is overkill.
If I take it in to change the filter and I get that kind of reaction again, I'll just take it home and do it myself, so I'd like to know what's in it so I just have to add the 1.5 qts vs 3 gallons.
