Many years ago (1973) the brits made an adventure trek with the (then) new range rovers through Panama. I had a IIa at the time and we entertained the Brits several times during their visit. I had a conversation with one of their wrenches one evening about my IIa and how it was running poorly etcettera. The mech suggested I flush out the sludge and "loosen things up Mate".

How we did this the following day still amazes me thirty years later and I wonder if anyone else has tried this?

We drained the oil and screwed on a new filter. He then poured two quarts of heavy motor oil and two quarts of diesel fuel into the crank case. Then we fired it up and let it idle for about 15 minutes. After that we drained the sump and dropped the pan to let all the mix drain and clean out the sludge left in the bottom of the pan. New pan seal, new filter and fresh oil and after a valve adjust and timing damn if the engine didn't sound nice and run well from then on. He related it was an old mech trick in the Brit army to prevent having to pull down engines using garbage for fuel and lube in the various parts of the world where they used the LR's.

Anyone beside me ever seen this or done this to their truck?

I used to add a quart of ATF to the crankcase and drive around the block a few times. Basically the same concept.

Don't synthetics these days keep engine guts cleaner? Some threads say when you switch to synthetic you pick up oil leaks due to the sludge being washed away from seams, etc.

I bought a $50 Corvair years ago that had sat for years. Filled the crankcase with kerosine, pulled the coil wire and cranked several times. Then drained it and put in fresh oil. Since diesel etc are fuel oil anyway I didn't wory about pulling the pan. Worked great. Used the car 2 years without any atroulbe (course pancake air-cooled motors are pretty damned tough anyway.

Pretty common Jerry. Then again the average 2.25 petrol would probably run for a good long while with diesel for motor oil. On a V8 I don't know if the results would be as good.

I did the same thing to a '71 Chevy I used to have. Oil and Kerosene mix, pull the coil wire and crank it over for a good long time.

Refill with oil and a new filter, drive for a day and change the oil and filter again.

An alternative is to use Rislone- I hear it's easier on the engine. Anyone tried this?

No. But I have used this in the crankcase:
