RE: [DML] 15W40 oil brand

["John Hervey" <john@xxxx>]

Cecil,
As I understood oil gets black over time due to fuel that goes past the
rings and dilutes it and when the cylinder fires some exhaust goes by the
piston rings and that is what turns the oil black again over time. How ?
does this type of oil stop that.

I just pulled the pan off my engine after using only Mobil 1 in it for the
last 9 years. ( no problems but tapping the block for turbo installation)
The pan was clean with absolutely no sludge or grit. The car only has 26k
but it is over 20 years old too. I have pulled apart quite a few engines and
this is by far the cleanest pan I have seen.

It has made a believer out of me. I am sure there are many excellent oils
but for the occasional use many of our cars get I like the synthetics.
