Anyone put Seafoam in to the crankcase?

If you change oil on time nothing is needed. I have used raw diesel fuel in the crankcase after a drain to clean. Run for about two min. and drain after putting in.
I do this with both vehicles and farm tractors but mostly use mineral spirits. Agree with the engine run-time too, that's very important so don't get distracted [;)]

Once a motor is sludged to the level of being able to scrape, any additive that may loosen the sludge, will be problematic. The sludge once free, if not totally dissolved can/will block oil passages and starve critical moving parts.
I had the diaphragm on my fuel pump break and it released gas into the crankcase. This was on a 74 Dodge Power Wagon with a 360. It trashed my engine. Its never been the same.
If you have a stuck lifter or some noise in the valve train I would add some Auto trans fluid like dextron II. They have a lot of detergents in them and will help clean the engine without thinning the oil.
Use a high quality motor oil and filter, do you oil changes as per the schedule 3-5K and it should be fine.
I didn't notice a difference in anything, nor did I notice any problems.

That's all ya gotta do. Doesn't have to be synthetic, although in today's world there is no reason to not.
No Penzoil, no Quaker State.
The Nissan just turned 453,000 miles.Had to change the valve cover gasket last summer and everything still looks clean.Used Mobil 1 since new.
What oil change interval? Mobile one is great stuff. There are some independent lab tests out there and mobile 1 ranks extremely high in every one.
With today's modern oils and with modern engines having the positive crankcase ventilation system sucking the fumes out it might not be the problem it was but it probably would still be a good idea to limit the times when a motor is started and shut off before completely warming it up.
I put Rotella Full Synthetic in my New Holland/Ford diesel mower this year.
Switched to Chevron Delo 400 Synthetic 5W-40 a couple years ago. Have run regular Delo 400 15W-40 for 35 years.
This is a one oil outfit. Everything from the lawn mower to the log truck.
Auto trans fluid works for me. I have use seafoam in motorcycles with no ill effects.

YEP..... Worst thing you can do to a sludged engine
I spend a little extra time and pull the valve covers and oil pan off if I think that it might be sludged up and clean up by scraping the sludge way and then cleaning it with a degreaser outside the engine

If the engine is so filthy as to require running solvent through it, I recommend a teardown.
