New to me this truck. Its a low mileage truck, 38K miles. Last owner used it less than 1K miles for last year owned. Are there fuel additives that I may consider adding when filling up to "clean" out system...or is it needed. Truck runs decent. I think its under powered but...(other truck 2001 with BOMs).

Thanks

I've tried Howes, Stanedine, and Power Service, and just lately Sea Foam, Sea Foam is the only additive that has made any difference at all, and the difference is pretty impressive.... running POD injectors can be a pretty smokey thing, and Sea Foam has almost competley eliminated the haze/smoke. You can use it as a fuel additive or a oil additive.
Do a google search to read about it before you buy it.... I like it

I have never tried the SEA FOAM, so cannot say about it.

From what saddog has said, I would probably give it a shot for system cleaning.

I would run a dose through it, before swapping fuel-filters, then swap filters and run another dose in it.


For winter, I mix 8-oz Marvel Mystery Oil and 12-oz white-bottle Power-Service to each twenty-gallons of fuel.

In summer, for added lubricity, I will use whatever slickum is at hand, usually one-gallon-to-twenty used engine oil, or 15-oz-to-twenty STP, or one-quart-to-twenty cheap engine oil; anything to try to put back what the communists have taken out of our fuel.




I will also add this :

If the engine is running good, I would restrain from any drastic fuel-cleaning measures when below-freezing temperatures are expected in the next several days.

It might just carry a load of trash and water through ice-cold fuel-lines and shut things down.

I cycle powerservice grey bottle through mine every other fillup, works great for me. Ive used seafoam, but $6 a shot, versus $7 for the powerservice that does 3 tanks, keeps me away.

I have tried it all. Powerservice, Howes, Stanadyne, or Sea Foam would all be good insurance. I can tell I have had great luck with seafoam in everything. I have no trouble paying the 6 bucks a can because the stuff has not let me down. Menards is about the best price in town on it. and it will go on sale for 4.88 which is when I stock up. Beside seafoam I think all the other 3 are par and I believe powerservice would give you the most quanity for the buck IMO. Use the white bottle of power service if you go that route.

I'll agree with that too. Wait until its a little warmer and have a spare filter on standby which you should have in the truck anyhow.

there are alot of soy based additives they work the best. there was a test on comp diesel that tested almost all of them out their and the soy based ones came out top 5.

I recommend Stanadyne for a decent all-around "do it all additive", Howe's Meener Kleener for a truck that needs a cleaning, and plain old 2 stroke oil for regular lubrication.

My truck gets Power Service white bottle in the winter for anti-gel because it's cheap and easily available, and Wal-Mart 2 stroke oil (1 qt. per tank) year 'round for lubricity.

I use 1/3 bottle grey power service every other tank, dont know why, i just do. lol

As for cleaning I use Lucas fuel additive/cleaner every tank, it also lubricates. For every 20k miles or so I run Sea Foam, IMO nothing cleans better.
