Why would you say this? Many 'flush' products, including MMO, have a significant solvent content. If you disassembled your engine, you would probably clean the parts in some kind of solvent. Are you suggesting solvents added to the oil would have no effect?

I would never flush it. I'd run a couple OCI's of Pennzoil 10W-30, short OCI's depending on how black things get. Then, I would run Mobil 1 High Mileage 10W-30, maybe 10W-40...

This is an opinion-based forum, I gave mine. My opinion was learned from a lifetime of experience. They will do little more than separate you from your money. Your results may differ.

All of the "poor boy" rebuilds I cleaned (at best) meant a trip to the car wash with some cans of engine cleaner then some gas that was drained out of something, usually the thing we were working on.

If the level of sludge is what I picture in my mind, no, store-bought additive in a can will do nothing.

I understand the opinion bit. But according to your experience, you could tear the engine down and clean it. Or, you could try a solvent in the oil. It sounds like you only do in the former.

If you disassembled your engine, you would probably clean the parts in some kind of solvent. Why wouldn't solvents added to the oil have a similar effect?

Actually, If the heads have been hot tanked they are now squeaky clean. Clean the lifter valley as best you can with rags, screwdrivers etc and you are in pretty good shape.

Those are the 2 biggest areas where sludge accumulates. If you suspect a bunch of sludge in the pan and pump screen, put diesel or kerosene or gasoline in and let it soak a few days. Don't run it. Drain, then repeat until it looks clean. Get a pan heater and let it cook. The hotter you can get the solvent the better it'll break up the sludge.

approved For people who don't have the time, knowledge or resources to tear down an engine, this is what I'd do. Cheap easy to find and it works. If you don't mind sending away for a product which has a money back guarantee then I'd try Kreen which is stronger and faster acting than MMO. And if it doesn't work they'll send you your money back.
Just keep an eye on the oil level and change the oil filter early for really dirty applications. Very heavily sludged engines should be manually cleaned if possible.

I used it many times and it doesn't live up to any of its claims in any engine i tried it on.
The only thing it cleaned was my wallet.

It would be good to know what were really dealing with in this engine. Chunky sludge? Heavy varnish? Just basic thin coatings?

I knew what my engine looked line under the cv and in the oil pan, and so I did the B12 chemtool idle flush recently with good results. I wouldn't recommend it to everyone, but it is so,etching to consider if you're looking to do something a little more stringent.

I'd probably start with some HDEO with Kreen or MMO over a couple OCIs first though.
