Fuel Additives

Keep in mind that just because what you put in your tank adds lubricity, it doesn't mean that it will be good for the injection system.

Also, many diesel fuel additives do more than just add lubricity.

It doesn't mean that it hurts it either. I don't think it would be in the study if it was harmful. It's all a matter of opinion I guess.......:cheers2:

I can tell you this. I was involved in that study. I contributed to it financially and with suggestion for additives to be tested as well as the reporting aspect.

The decision to include an additive in the the study was not base on whether an additive was good or bad, but simply based on requests by various members of the forum. Some of the tested "additives" were deemed by many to be detrimental to the injection systems and/or emission control equipment, but they still were tested because people wanted to know how they affected lubricity. And LUBRICITY was the only thing tested, nothing else.

If you look at the results, several of the additives failed to provide even minimal lubricity to the fuel and some even made it worse.

Keep in mind that this was only ONE test of diesel fuel additives. There are many other tests that can be performed, but time and especially financial constrains prevented more comprehensive testing.

These test results should be used to compare ONLY those tested samples for their ability to provide lubricity to the fuel, nothing else should be derived from these results.

Hope this helps those who may still have questions about this test and the results their in.

Cheers. :D
 
2 cycle oil = high ash content. High ash content = dirty burning product and in most cases dirty injectors. Why in the world do you think 2 stroke spark plugs fail and get Carboned up so bad. imagine your 50,000.00 trucks 8 cylinders looking the same.

Lubrication isn't the only thing you need to look for in an additive.

I have had engines apart where customers have run 2 cylce, 100% WVO, it's not a pretty sight.

It's deffinetly worth the money to purchase a good product.
 
Is TCW-3 rated not ashless? It has been stated on here and other forums time and time again that this particular rated 2-cycle is ASHLESS. No or yes?
 
I've run FPPF Total Power in every drop of diesel fuel that has been burned in my truck since day one. I've also been adding 1/2 ounce per gallon of TCW-3 2 stroke oil for just over a year since SE Idaho went ULSD. Still on my original 2001 injectors at 7 years and 154,000 miles.
 
I wasn't real happy with the perfomance standyne either when I tried it. I noticed no difference at all
 
I ran Stanadyne Performance Formula religiously in my 99 6.5TD Tahoe because it had a Stanadyne IP. I would still be running it today in a 6.5TD to add further protection for the IP with ULSD, but I personally don't think Stanadyne PF is the best choice of additive for a Bosch HPCR system - not that it's bad, just formulated for a different system.

Keep in mind the SPICER test was for lubricity only. I still use Stanadyne products. Lubricity is only one of the benefits that their products provide. I've used Performance Formula since day one. Occasionally I also add their Lubricity Formula when I'm on the road and can't fill at a high volume truck stop. So far, with over 34,000 miles I have never had any problems.

My block heater has never been plugged in and the truck has always started in the winter even when it has been sitting outside overnight for more than 12 hours at ambient temperatures of -10ºF with a windchill of -40ºF.

Stanadyne products ARE approved by GM and I'm sure there are others that are approved as well. With the price of LBZ injectors running over $1,000 each, I simply don't intend to take any chances by using additives that GM specifically states in writing NOT to use.

Everyone makes their own choices and then lives with the consequences. Remember, "CAVEAT EMPTOR".
 
Well I've had good luck with Power Service products for over 100k and it's readily available as well as better than nothing. White bottle in winter and silver bottle (Diesel Kleene) in summer. I like having some reassurance of lubricity additive and also to keep the pump/injectors clean. One thing nobody has mentioned is that the refiners are blending in a lubricity additive with ULSD. Remember that we here are all a bunch of fanatics while for every one of us there are probably 20 or more that aren't using any additive with no problems...

I feel much better now.....:hurray:

I do run a 1/2 tank of 20% bio at each fill-up hopefully that will further offset the lubricity issue with ULSD.

Just a minor point - the refineries are NOT putting any additives in ULSD. As a matter of fact, the refineries have to get it into the pipeline at around 8 ppm in order for it to arrive at distribution below 15 ppm. All additive packs are added at the distribution centers as the trucks are being filled. This is a "batch dump" addition that may or may not be properly metered and may or may not mix thoroughly with that truck's load of fuel. That's why we do not mind taking a little precautionary action to add lubricity additives to our fuel just because of the low lubricity in ULSD and the possibility of poor additive treatment by the distributors.

Idle is right, it's cheap insurance.
 
Yeah Tom, I guess I knew it was a distributor add, but I'd think with a business reputation to maintain that the mix would be fairly accurate. Having said that, you see I'm still not trusting enough... Actually, I wish that B10 was readily available to me. Only one along my route and I have to go around to the truck islands and YOU KNOW that's at least 1/2 hr of screwing around to pay and be gone... I could get some FS B20 but they're a bit too proud of it at a 10 cent min. premium.
 
That'a interesting the co-op around here is a few cents per gallon cheaper for their B20. It may be that the co-op's location (outskirts) that lets it be cheaper, but it's on my way home.......:hurray:

Where do you find Stanadyne? I looked for it but all I found was Power Service. I got some and put it in the tank but I also had 13 gal of LSD in there. I usually only run that, but I was out of town and could only get ULSD.
 
The best place I've found so far is The Diesel Store...best case price delivered and I've been buying it there for the last 20k miles...

If one of our vendors has it - sorry...I didn't find it.
 
At least if you use an additive you are paying attention to your truck and thats a good thing !


I had a old 6.2 and used PS in it with no problems but then again I could pour coffee in it and it would run. Tough old truck, no power to speak of but tough.

When I got the LMM I spoke to RayMich on another forum as he seems to be very knowledgeable, and based on his recommendation started using Stanadyne PF from the start at about 500 miles (odo.). I keep very close records on all aspects of my truck as well as fuel usage and mileage. The truck now has close to 9K on the clock and I never missed a tank without the additive. By my calculations the Stanadyne never improved mileage but never hurt it any. No gelling problems and it ran pretty well.
Recently I switched from Stanadyne to FPPF based on the lubricity study as well as input from Kennedy Diesel and my interpretation of some other info I found on additives. I run the "Kennedy Cocktail" which details can be found at Kennedy Diesel web site. I could tell a difference on the first tank ! The truck runs quiter and so far I have picked up a real 1.5 MPG. This is great considering my goal of an honest 20 MPG / Hwy at 70 MPH. with current mods. I don't have all my mods listed on this site but I use the same name on Diesel Place.
#2 Diesel fuel in N.C. sucks and anything that can be done to help improve its quality is time well spent IMO. Time will tell if things work out down the road but I am very satisfied to date.
