Amazing. Amazingly stupid. Oil contamination with fuel and
combustion byproducts will dilute the oil ( not good ) and turn the
oil acidic, and acid and metal do not like eachother. Not to mention
all the micro-metal debris along with carbon particles floating around
that make it through the oil filter.

Never go to a shop to have your oil changed. They will give you the
cheapest **** imaginable, to keep their profit margin as high as
possible.

Are you aware that I wouldn't stop at a Citgo station if I was down to
my last drop of fuel?

Yah. They take that dirt into solution, and bathe all your engine
parts with that dirt. Bearings, cams, valves, the entire works gets
washed over and over with MUD.

Eventually this MUD becomes so thick it turns into sludge, which won't
come out with your next oil change.
