I filled the fuel tank up Sunday, and decided to throw some 2 stroke oil in the tank to make up for the poor lubricity of the ULSD fuel.

All I can say is, significant difference....definitely recommend doing it. Truck runs and idles smoother, and is noticeably quieter, now that the fuel system is properly lubricated. This is definitely good protection for the fuel systems on these trucks.

Make sure you use a 2-stroke oil that is twc-3 certified, and use 1oz per gallon of fuel (128:1 Ratio).

I was going to run it for a couple weeks before posting the results, but the results were pretty much instant. Ill post if there is any fuel mileage improvement.

Up from 15.3 mpg average, to 15.9 MPG....Im going to run another tank of fuel with the 2-stroke and see if the results stay the same since I drive varied amounts of city and highway. 477 miles this tank.

Truck is still running noticeably smoother, so this is worth it for the sake of the fuel system regardless of any mileage improvements, IMO.

Cost is close to just buying another gallon and a half of fuel at every fill up.

Shes going to the body shop for the next couple days, so it will be another week or so until I will be able to check the gas mileage again.

I've seen on other forums that some use the two-stroke oil and others use Marvel Mystery Oil and some use a combination of things that could include either of the previous mentioned or a product called Power Source (I think that is what it is called) Stuff like this can be subjective but if it works then why not. Do a google or similar search to see what other have done on other forums as well as this one which has many excellent postings on a variety of subjects and maybe on one like this subject. I know if anyone is running the new 6.7 I would be careful using anything that might clog the catalyst.

does this affect the VP44? im on the second VP44 and the fuel pump went the firsr time around, i think its the low sulfur content in the ULSD that is doing the killing.

This is to help lubricate the VP.

I have been running it for over 35k miles and I love it. And for you stock guys, it adds a little smoke.

Also, I run the walmart house brand outboard 2 stroke in my truck. Its about $10/gal and lasts me about 3 fillups.

should i drop the oil in first then fill her up? what if i ran a little on the lean or heavy side, i don't usually run below 1/4 tank so its always a variation in the gallons. any noticeable size effect when running lean or heavy on the mixture? I have to fill my truck up tomorrow so i'll be trying this out.

CONCLUSIONS:

Products 1 through 4 were able to improve the unadditized fuel to an HFRR score of 460 or better. This meets the most strict requirements requested by the Engine Manufacturers Association.
Products 1 through 9 were able to improve the unadditized fuel to an HFRR score of 520 or better, meeting the U.S. diesel fuel requirements for maximum wear scar in a commercially available diesel fuel.
Products 16 through 19 were found to cause the fuel/additive blend to perform worse than the baseline fuel. The cause for this is speculative. This is not unprecedented in HFRR testing and can be caused by alcohol or other components in the additives. Further investigation into the possibilities behind these poor results will investigated.
Any additive testing within +/- 20 microns of the baseline fuel could be considered to have no significant change. The repeatability of this test allows for a +/- 20 micron variability to be considered insignificant.

10)Power Service Diesel Kleen + Cetane Boost
Multi-purpose
Cetane improver, bio-diesel compatible, alcohol free
HFRR 575,

61 micron improvement - Talks of the lubricity improvement of the fuel.

400:1 ratio - 400 parts fuel to 1 part additive.

8.32 oz/tank - figure a 35 gallon tank with the 400:1 ratio as listed above

$1.58/tank - cost of additive per tank

This help?

I ran Wallyworld 2-stroke a couple of years ago and instantly noticed a quieter engine/injector pump. I ran that for about 6 months and liked it. Then I started blending WVO with my fuel. I now run about 5 gallons of WVO per fillup and notice no difference in performance. The only difference is the smell. Has a distinct smell of fried foods.
