Just call me Colonel Angus
A long time ago I thought Mobil 1 wasn't any good because it turned very black soon after I put it in my car. Turns out it was my fault for not changing the oil soon enough, and it turned black because of the dirty oil that wasn't drained from the engine. I soon changed it again and it was much cleaner the second time....Next, I will get it started, and see how much oil we have to add, and see how clean the oil is after it runs a few minutes.
Have a good one ???
