Thanks for posting this. It TAKES reading to believe that my old stand by MMO is abrasive with the new fuel. I have used it Twenty years, but now have already switched to two-cycle oil...I just not make myself burn straight de-sulfured diesel fuel...

That is a pretty informative study:thumbsup:

There are a couple of things I would have liked to seen them do differently though. and since that study is 4 years old, maybe someone else has a more current study.

First, I here a lot of people say they use the ATF. One quart per tankfull. That is about a 250:1 ratio. I would be curious to see a study of how well the ATF worked in a scientific way like this.

Second is the two-stroke oil. They used "walmart brand" supertech:confused2: Why not use a better 2-stroke and see if that helps:thumbsup:

And some of the things on there that are like ~$4+ per fillup:confused2: Is it really worth it. IS this ULSD really causing that much problems?? Because I am sure there are FAR more people who do NOTHING than people who use additives.

@$4 per fillup, and ~26gallons per fillup, that is almost $1000 in additives alone every 100,000 miles. IS that really cheaper than doing nothing and having to have the fuel system rebuilt a little more often??

If you own a boat and are a member on Iboats.com, you would read that Walmart supertech oil is highly regarded as good stuff. Many of the main guys including mods who put hundreds of hours a year on use it no one has had bad results from it that i have read.

The secret that the oil companies wont tell you and there was a guy who either worked high up in walmart logistics or for an oil company , i think, said that the stuff is left over batches of name brand anyway. We all know there is no supertec factory somewhere. They get batches of Penzoil castrol etc. The only thing is one batch of supertech may be 60% penzoil marine, 30% warren oil and 10% castrol blended togeather, you just dont know. Some also suspect it to be right out of company x's vats 100% pure?

Over on the dodge cummins forum 1oz / gal of fuel formula is what they recommend - BUT that was also for the outboard motor oil that was TWC-3 formula. Not sure if that is what you have or not

I think most 2 stroke oils on the market are TWC3. I checked over the weekend and everything on the shelf at my local auto parts was TWC3.

I'd like to see that with the 2-stroke oil increased to 1oz/gal instead of their 200:1 ratio. I read a study somewhere where they had used the 1oz/gal and it improved the lubricity better than any commercial product. I'll see if I can find that study again.

Id there some sort of benefit ?I should know about and be adding on purpose?

the benefit is added lubricity - especially on the Dodge/Cummins with the lift pump

So I have a question,
in my 1995 L2950 I have a 5.5 or 6 gal tank and I have several quarts of injection oil sitting on a shelf like you use in a sno-mobile. Can I use this oil? and if so how much per 5 gal can?

If the ULSD you are pumping has even the slightest bit of "Bio" in it and it almost certainly does, adding anything as a lubrication enhancer is simply unecessary.

The biggest problem with injectors, pumps and diesel fuel systems is lack of proper maintenance. Then people was a "fix-it-in-a-can" and that product does not exist.

I add TCW-3 to my fuel .About 4 oz to my Cummins when I fill up

Remember adding trans fluid to road fuel will make it look red like off road fuel.

good thought
