ive had pretty good luck with it in 5.9s that were in tractors and stationary power plants. i like to mix some lucas fuel treat in with it if the fuel filter has enough room to. dont run it every fill up tho. it is quite a cleaner. i saw a moron that thought he was smart go out and buy a case of it to put in a really old 5.9. put the whole case in the tank with about a pint of atf. poor thing didnt last 5 min before the injector pump started to give out.

Dear Mr Land Rover Master Mechanic,

I have to respond to your comment and misinformation about your alleged misinformation.

Seafoam contains 10-20% IPA 67-63-0

For those who are too busy working on overpriced automobiles and becoming just a Land Rover Master Mechanic instead of an ASE Certified Master Tech, IPA 67-63-0 is Isopropyl Alcohol, I bolded the letters of importance.

Also attached is the MSDS for Seafoam. Those doing the "Homebrew" Seafoam are far from being "Real Seafoam" though the end results may be similar.

Here is the "true seafoam" recipe straight from the MSDS that is also attached to this post.



Pale Oil 64742-54-7 (AKA Hydraulic Fluid) 40.00 - 60.00%
Naphtha 64742-49-0 (Can be bought at Lowes) 25.00 - 35.00%
IPA 67-63-0 (Isopropyl Alcohol) 10.00 - 20.00%

I am not going to dispute the quote that it is 100% petroleum, though I believe it is a stretch. It takes Propene, which is a hydrocarbon and a byproduct of oil refining and natural gas production, to produce Isopropyl Alcohol so I guess technically it is petroleum by association....

So to conclude this, it seems there is a wide variation on the percentage of the 3 ingredients in Seafoam. But there are only 3, and they are all easily obtainable. I don't know if the percentage range is just to throw people off from duplicating it or if that is their acceptable range. If so then one lot being made might contain twice as much alcohol than the previous lot, so the can you get today might be different than the can you get next month.

I'm still going to use the stuff......

Thanks, Benjamin

This is some good advice. You should listen to yourself more often.....

I work for a large landscaping company and we usually keep 2-3 cases of Seafoam in house. We run it in everything from small 2 stroke weed trimmers up to and including our dump trucks. A couple of our trucks have the 4.5L powerstroke and the larger ones have B series Cat's. I haven't seen Seafoam cause any problems in our equipment, ethanol is more of a problem then anything else.

The complete recipe. MSDS sheets only show ingredients that the government has classified as hazardous. This may or may not include the complete ingredients list.

I haven't used it in my diesel fuel. I have in a ton of gas engines. I do use it in my oil right before an oil change, every 100k. The idea was given to me when i bought the truck used and after 3 oild changes @3-5k using Synthetic oil they were chuniky andjet black, I was changing it when it got black. I was talking to a Cummins engine tech, and he said they run it for about 5mins in oil, then drain as soon as they shut it down. That was the chunkist oil i have ever seen, but have never had a problem again.

For fuel side, i use PS and Lucus in every tank.
