The best way to remove engine sludge is to prevent it. Adjust oil change
intervals according to operation parameters.
Lots of highway miles for example are better than short trips that don't
warm the engine up. If the engine sits a lot change the oil every few months
or, for synthetics, check with the oil manufacturer. Always change the
filter with the oil.

Definitely no argument there, Budd, but when you are in the business,
as I was, you always ran into the guy who "knew better" and was proud
of the fact he never changed the oil, or the guy who was just
forgetful and neglected to change the oil, or the guy who used the
cheapest oil he could get.
Or you got the guy who bought the car one of those guys used to own.
In those cases, the judicious use of a flushing agent was often
necessary.

Not only have I met him, when income for my family was below non-existant, I
made him look like he changed oil too often. A slant six and a 383 I had
went for 5 (/6)and 4 years (V-8) without oil changes, but I knew that wasn't
right . . .just no money for 5 quasrts of oil. Was it right? No, but it was
neccessary.
But I agree with you, there are some that think oil changes are stupid.

I had a 64 1/2 Barracuda (yeah, the really rare one and my second ever car)
that had black sludge on the rockers when I got it (273 V-8) and it took
seven oil changes with the old thin viscosity Wynn's Friction Proofing to
clean it out, each change being run only 500 miles between changes with
filter each time.
The previous owner? An elderly man that got it for his birthday in early 65
right after they came out then died in 67 years later which was when I
bought it ($950). He only put 20,000 miles on it but they were all short
slow trips and the original filter was still on the car.
