Well, I have put all sorts of snake oil in my tanks. However, the best stuff I have ever found was on the injector tester bench. I took out 6 injectors out of my MB diesel and had them tested. 5 were good and one was spraying badly and had lower pop off pressure. They disassembled it and cleaned it till it was just as good as the others. Power was a little better and ran smoother according to the wife who didn't know what I did. So, before I spend money on that snake oil, I'd make sure the injectors were good or bad. I would do my MB again after 100K. For the truck, I would probably do it at 150K.

stanadyne is good. you mentioned seafoam. not familiar w/ it but a tech on our ford message board said a customer poured some of this down his intake & damaged some of the pushrods & rockers. don't do this. thought his eng. was damaged for good. its probably just as bad as using either & too much at one time. either is not recommended for these engs.
Hi kan. After reading this thread, I logged onto the Sea Foam site and found these directions:
1. Fill primary fuel filter with SEA FOAM. Be sure filter is fully primed to prevent air locks. This will clean injectors quickly.
2. Use 1 pint of SEA FOAM to every 25 gallons of diesel fuel to add lubricity, clean fuel lines, injector pump and remove moisture.
3. Use 1 pint of SEA FOAM to every 4 gallons of oil to clean rings and other engine parts internally. For best results, use SEA FOAM for 1 hour before oil change. Results in cleaner engines and longer oil change intervals.
This lists three 'separate' procedures for the product. I don't know about you, but it takes me about 2 hours to replace the fuel filter, so I really don't want to get into that. However, adding it to the fuel or oil just before changing wouldn't be a problem. Which of the the 3 procedures do you follow? Or do you do all three?

I have used Stanadyne for years about every 3rd tank. I recently tried Howe's and got the best MPG so far in my truck. It only picked up just under 1 MPG, but with these fuel prices, every little bit helps.
I have used 1 & 2, both with good results, option 2 you will notice a differance within a tank. Option 1, you will notice a differance within a few seconds. Just bleed the fuel canister, fill with seafoam, start like you would when changing a filter, smile, drink a beer, or in my case a Makers Mark and water. Bourbon mixes with water a lot better than diesel.

You only need two tools: WD-40 and Duct Tape. If it doesn't move and should, use the WD-40. If it shouldn't move and does, use the duct tape.
1) You drive or idle the truck for the suggested 1 hour?
2) The amount of time after you add SF and run the truck until the oil can be changed?
i only ask because I have about a 45 minute ride to work, but then it would be 4-6 hours until I could actually change it. Just wondering if it would be better to put it in before I leave and then change it when I can, or to idle it for an hour before I immediately change it, or 3) wait until I'm home...
