I have been running the 1 oz per gallon 2 cycle oil in my truck for the last 4 tanks of fuel. I have not noticed any MPG gains, no smoother running. I am sure it helps the internal parts out thoe. I just took a 1600 mile round trip with it and i was only getting 17mpg on the freeway at 80 mph.

 

well, ive always thought that the syn 2stroke would be harder to burn...plus its more expensive. petroleum 2 stroke works just fine.

 

I wouldn't think 17 is too bad at 80.

I use B-20. Which is 20% biodiesel I think. Someone please correct me if I am wrong. -------- Before I found the close to house B20, (same price as ULSD) I was using ashless TWC-3 from Wally world, pretty cheap buy the gallon, I used I qt to a tank. Someone said they thought that was a lot.
Actually it is only 1:1120- ergot; 32 ounces in 4480 ounces (using 35 gallons X 32 as my tank capacity) since 4 ounces to a gallon is 32:1 -- =128oz/gallon ---4480/4 = 1120 I think my math is correct but it is late,so someone tell me if it's not. Anyhoo, my point is 1 quart in a 35 gallon tank ain't overdoin' it. I've read or heard that biodiesel is EXCELLENT Lubricitywise. Even better than the plain old "low sulfur" -- before the ULTRA LSD. I don't plan on using anything else other than B20== Unless it gets very cold. Do any of you think I should use anything else besides B20? For other reasons I am unaware of ? I do realize that although Cummins says it is perfectly OK to use B20 Dodge Motors does not approve its use. (What does Cummis know, they only design and make the engine) Thanks.

 

nelrod, all I know is what I saw on the side of my truck and inside my motor which I posted pics of about a month ago. can only imagine what that much carbon would do to your cat. cummins recomends WAY less oil . the old lubricant in diesel fuel was sulfur which was measured in parts per million , not ounces per gallon. thats what you are replacing. if 1 qt per tank isnt burning cleanly and is building up as carbon in the combustion chamber, and through the entire exhaust than its obviously to much oil. a pint burns clean and still does the job and costs half as much with less polution

 

Super, thanks for info. I no longer use it, as I use B-20 now. I see your point, if a pint does job better, don't use any more than nedded. Also Super, FYI, the sulfur is NOT a lubricant. It is the PROCESS of removing the sulfur from from diesel oil, that cause some of the aromatics to be removed, which cause a lot less lubrication. It's what I read about it anyway.

 

16oz/per tank been working great for me.

 

Has anybody tried this stuff? http://www.fppf.com/lubricity100.asp. They also have a couple of other products. This is the same outfit that came in third in the lubricity test that some guy did over on the Diesel Place.com

I am thinking of switching to 2 stroke oil as well. But I have been getting good results from my 5 gallon pail of amsiol diesel fuel conditioner. Every fill up I add the recomended 1 : 640. The cost is very comparable, maybe even in favor of the amsoil. Will have to do some # crunching when my amsoil runs out in about 6 months!

 

I found this link and thought it was an interesting article, It from the diesel place forum

p.s. I have been using Amsoil synthetic 2- stoke for snowmobiles at a 100/1 ratio. ????? It has to help, right?

 

I was fortunate enough to speak at length with a Cummins engineer back in May. I asked him if it was harmful to run 2 stroke oil in the HPCR engines and he said he would DEFINITELY not add oil to the fuel. The engine is designed to run without additives. Take it FWIW, but you guys know there are a certain element of posters on message boards who want to be "Johnny on the spot" with some new miracle trick. Anyone who claims their mileage has gone way up and their truck runs better is suspect to me. You know what they say about something that sounds too good to be true.

 

I agree with this guy. If it were a good additive, it would be labeled and sold as one.

 

If you add oil to your fuel, and your truck runs better and gets better fuel mpg, you may have a sticking FCA.
