in my old mazda truck, before every oil change i would idle the truck for 10 minutes with a bottle of atf and a cup of paint thinner in with the old oil. Then drain it and add new oil to the case. I have yet to do this on my dodge.

The ATF trick works well, just don't run it at highway speeds during those 10 minutes!

Well flushing is not recomended for a vechile that has been neglected. The last thing you want is for a huge piece of sludge to break loose and plug pickup screen or oil galley. If you seriously want to flush the engine go to Walmart or Auto Zone. You want to pick up a pint of B12 Chemtool. Put the pint in your your vechile(while cool not after it has run) and run it at fast idle(1000-1500 RPM) for 15 minutes. Drain your oil and refill. Amsoil also makes a flush. A safer and weaker soultion is to drain 1 quart of oil out of you system and replace it with a quart Marvels Mystery Oil. Marvels is pretty weak. THe 5 minute oil oil flush you see in the big can at stores is simply a quart of kerosine and will also work. I am not a big fan of chemical flush's. Their are numerious cases of people spinning bearing or pluging up their pickup screen with big hunks of sludge that have broken loose. It is always bettter to drop the pan remove the valve covers and start scraping out the sludge. Proper maintence and a good oil changed at the apropriate time will prevent this. I relise that often the damage is done by the privious owner. Just use caution!!!

Once again Sandman offers good advice, and I would like to add ... The big concern with the 10 or 15 minute flush products is that they are thin solvents that may loosen big hunks of crud ... but not fully dissolve them. If these loose bits of crud then move around and plug an oil passage, you get the priviledge of writing checks to fix your engine.
I would like to recommend two products Amsoil Engine Flush when SWITCHING a "higher-mileage" vehicle from dino to synthetic, and Auto-Rx for a SLUDGE PROBLEM such as yours (check this out sandman ... www.auto-rx.com Auto-RX.
Per the company, Auto-Rx is a synthetic, biodegradable, highly effective, safe metal cleaner. Auto-RX is gentle, slow acting, and thorough. I know many vehicle owners that have used it and no one has reported any problems. I feel that for SLUDGE PROBLEMS ... Auto-RX is a better choice, and for a FLUSH prior to switching from dino to synthetic Amsoil is an EXCELLENT CHOICE.
Auto-RX is inert in your oil,it does not negatively affect any aspect of your host oil except to clean and disburse crud to the oil filter. There are no negatives associated with it's use. Auto-RX was developed as an alternative to solvents for a slower non hazardous alternative that does not deplete, but ends up disbursing the crud in a very small form ... small enough to flow by bearings etc.
If you decide on this Auto-RX product (For the record ... I do not sell it) FOLLOW THE DIRECTIONS RELIGIOUSLY. Then I hope you visit my website, request a free catalog, and become an Amsoil customer.

Agree with the Amsoil guy,
Avoid the The "quick fix" flushes. There is a very real risk. If you use this stuff on a very dirty engine it will quickly dislodge large chunks of sludge which can clog oil passages and the oil pickup screen. A slower working cleaner which disolves the sludge into a liquid is definitely the safer way to go. Harsh solvents are not good on gaskets either.

Well Amsoilsponsor I ordered some Auto-Rx. I figured I had nothing to loose. I recently bought a car from my Grandmother and it has 107,000 miles on it. When her second husband was alive it only saw mobil-1 oil but after he died it was taken to fast lubes by one of my uncles. So it has been on a steady diet of 10W30 penzoil for about two years. I also think that the uncle was not getting oil changed when it should have been changed. I think he was going by the GM built in oil change indicator. I am going to pull the valve covers and check it out. If I see any visable sludge or not I will take photo and then after the second treatment I will take a photo.I will also cut open the filter and take a photo. I think that the group might find it interesting! The engine still has plenty of power and does not burn any oil but it does leak a little.

Randy,
Your first post was approximately 6 days ago. You can not fix the problem in 6 days. You would need 2 applications and you would need to drive a minimum of 2500 miles (see below - what is in parenthesis is my addition) for positive results. I do not sell Auto-RX but if you read my post above, I do recommend it.
You will need two applications of Auto-Rx® for engines with more than 100,000 miles (or sludge problems). Because of oil filter limitations, one new, clean filter will not hold liquefied contaminants generated by an engine with that many miles.
FIRST APPLICATION
STEP 1
Install new oil filter ** DO NOT BYPASS THIS STEP. You will need a clean oil filter to catch and store liquefied contaminants coming out of your engine. **
STEP 2
Pour full 12 ounces of Auto-Rx® into your existing oil.
STEP 3
Drive 500 miles, 750 miles if using synthetic oil; 1000 miles if using diesel engine.
STEP 4
Change the oil and oil filter.
STEP 5
Drive your car an additional 1500 miles with just the new oil and filter.
SECOND APPLICATION
STEP 1
Add the second bottle of Auto-Rx®
STEP 2
Drive 500 miles, 750 miles if using synthetic oil; 1000 miles if using diesel engine
STEP 3
Change the oil and oil filter.
The application for high-mileage engines (or sludge problems) is done.

Steven I do not think he tried the Auto-RX. I ordered mine the same night you recommended it and it has not arrived yet. I doubt anyone could get it any faster unless they had a local store that carried it which I doubt. THe price on this product is kind of high I can not imagine it being cost effective for a large store. I am guessing that he used an off the shelf solvent based flush. I am just woundering how he is determining that he has sludge in the engine and how he knows if the flush has worked worked.

Sandman,
Correct. I meant to start my last post with ...
"Randy, You must have used one of those 10 or 15 minute flush products. Instead I recommend you use Auto-RX which is gentle, SLOW ACTING, and thorough."
I posted the directions for all to see the process.

I did try one of the 10 minute flushes.The reason I think I have sludge is I would drive 5-7 miles and loose oil pressure. I put in a new sending unit and the same thing would happen. At firs I did not hear any noise comming from the valves.Now when it gets to temp. I hear a noise from the valves.If I let the truck sit for a day or two and drive the same thing would happen.Its like when it sits the sludge would settle. When it gets to temp. it thins out and and the sludge would start to move into the screen and block it.I cant afford to take someplace and Im about ready to give up. The truck is in great condition except for the engine.

A simple, quick, cheap test for water (borrowed from a friend). Cut a beer can down to an inch or so, put it over a candle or lighter, and put a few drops of the oil in question in it. If is sizzles or pops, it has water.

If you are losing oil pressure after 5-7 miles you are probaly suffering from excessive bearing clearance ( engine wear ). I doubt that there is sludge moving around inside of your engine otherwise you could drain it out when the oil is hot. It sounds like your oil is getting hot and thinning and not able to hold pressure. Try a 20w-50 it is a temp fix but it will hold more pressure. You need a rebuild.
