Cleaning Sludge out of your motor
 

Someone mentioned running a mixture of oil and diesel fuel in your motor for
a bit then draining. Can someone post that again??
Thanks

I hope not. Don't use diesel fuel in your crankcase unless you want to really
mess up your engine. Diesel fuel does not have sufficient lubricity.

The best advice is to forget the chemicals and simply use a good detergent oil
and change it often.

If you insist on a chemical cleaning, try Seafoam, available at NAPA (and many
marine supply stores). Put it in your crankcase, go run your engine until the
oil is good and hot, then change your oil. It is not as caustic as the typical
auto parts store "de-sludging" detergents so is less likely to dislodge chunks
of crud that can clog your oil galleys and wreak havoc on your motor.

I sure wouldn't do this to any engine designed since the 1920's.

If you want to desludge, the safest route is to add a very high
detergent oil, run the engine till it is good and hot, then drain
and change, plus filter. Then do this again. And maybe swap
the oil at something like 1000 to 1500 miles for a coupla changes,
always with new filters. Optional extras would be to add a can
of add-in oil detergent or Marvel Mystery. I wouldn't run a full
can of either of those more than long enough to get the engine
good and hot.

I usually run about a quart of kerosene thru any used car I buy when
I'm ready to change the oil the first time. I make sure it's a quart
down, add the kerosene and let it IDLE - note IDLE - for about 10
minutes then immediately drain it while it's still warm and let it
drain good while sitting for maybe an hour. I'm also one of the old
fashioned ones that pulls the coil wire and cranks until I get oil
pressure after an oil change instead of letting it fire up. Seems to
clean things up nicely but again note: IDLE! A buddy tried that with
a Chevy V-8 and took off across town without draining it. Got about
10 miles, AIR...
