Going on a 2000 mile trip with my M35A2 so I will be pumping a lot of road diesel at truck stops.

I had planned to use two-cylce oil as a lubricity additive. Went to get some and all sold out due to boating season.

I did get 8 gallons of bar and chain oil from Wally World. Listed as 30 weight and I imagine it has few if any additives.

Will this be all right to use, and if so is a gallon to a full tank (50 gallons) a rich enough ratio?

We use Opti-lube, one gallon will treat 600 gallons of fuel. There is at least one thread here on lubricity additives, and Opti-Lube came in second (first in aftermarket OTC products). YMMV.

Take 30W normal or any flavor NEW motor oil and dump it into fuel tank with a pint of naptha from HD, cheap stuff. I used Klean Strip VM&P Naphtha, which is an intermediate or medium naphtha.
You could try a light naphtha like camp fuel (white gas) or you could try a heavy naphtha like charcoal lighter fluid.
Doesn't matter. That multi fuel will run good with 90% new motor oil and If you fillerup with what they named pump diesel You would need something.
New motor oil, any flavoer is not expensive, changing out the hydraulic head IS expensive, if one could even get one, which one can not.

Several years ago there was a group buy of HH's from China. Several people installed them and have not reported any problems. People on SS bought about 20 and they were $350-400 each. Maybe it's time for another group buy.

Howes diesel treatment.

Most bar oil I've seen has additives to promote adhesion and prevent it from slinging off. It woukd not be my first choice.

I also use Opti-lube XPD. Great stuff. There was a test of most of the common lubricity additives for diesel fuel a few years ago. They actually measured wear on stainless steel with a microscope. Opti-lube XPD came out on top. Interestingly, some people have been using Marvel Mystery Oil as a lubricity additive. It not only rated poor, it actually showed an increase in wear over straight diesel fuel. Unfortunately, I also used to add MMO to my fuel until I read that report.

Just a little off topic but theres a guy on you tube bought a new truck diesel and hes been documenting this from the first day till today for the last 130,000 miles hes been putting garden hose water in his def tank and has not had one problem /code . That just makes me smile at all the money people have spent buying def all these years

Kindly elaborate. Wouldn't the additives help it cling to the pump's internals, aiding lubrication?

I found the report I mentioned that evaluated the different additives to increase lubricity. As you can see, several of the additives actually created a worse problem than straight diesel fuel.

I speculate, and that's all it is, that it runs a risk of gumming things up.

simp5782 runs the roads pulling a load more frequently than a lot of us. Seems to me that if some sort of fuel additive improved mileage or saved wear and tear - he might be able to weigh in on it.

Somehow, I thought I saw mention of a Multi-Fuel truck early in this thread.
Wonder if the additives were suggested more for that than a Cummins or a Cat?

 

[glcaines]

I use Opti-lube XPD in all of my older diesels including M35A3, FLU419, M1030M1 diesel motorcycle, John Deere 5520 and 4600 tractors. I don't bother with my 2008 Mercedes E320 Blue Tec or my 2010 F250 diesels as they were designed for the low sulfur fuel.

G'day everyone,...


Every second or third tank refill I pour in 4-5ltrs of engine oil.

Simple.

I've run filtered UMO for years in my Mercedes Diesel cars and the 5-ton. Nary a problem, but I did install larger fuel filters to begin with. A 10:1 ratio works fine.

I run GM canister types, with inexpensive inserts, the change interval being about the same as with regular pump diesel. This for thousands of miles now.

I've learned tacticals have 'hardened' pump parts to allow running in arctic environments so fuel lubing isn't as big a issue as with newer Diesels (that have cat converters and requiring ULSD). That info gleaned from a mechanic at a local Guard base, where they normally run JP-8 in tacticals.

Since I am not a chemist I am not going to add chemicals to my fuel that are not designed to be there. Ok all you want to add is new motor oil or two stroke. Fine but they do not cover everything we need as in to raise cetane, water dispersants, fuel stabilizers, rust inhibitors and last lubricity. I am now using Hot shots secret fuel treatment and at auto parts stores plus it cover all these. One small container treats 400 gal.

My Deuce ran happily on 90% new motor oil, long time boom boom GI.

What about the new Duramax and the CP4 and the dealer telling the new owner to add good fuel additives to protect it. Why try and make your own mix of anything when you can buy it at the auto parts store and the bottle even tells you how much to add. Also I will try and find it again but report said burning Naptha it produces a high amount of carcinogens. I feel this is bad info and bad for the environment lowers cetane and decreases lubricity.

 

[plym49]

Thanks for all of the replies.

I am only interested in lubricity for the hydraulic head/pump for a multifuel engine. I don't need anything else (cetane, antigel, etc.).

Will 30 wt bar and chain oil be ok (since this is what I have)? And if so, is a 50:1 ratio too thin?

 

[plym49]

For those that have suggested it, what is the purpose of adding naptha to the recipe?

 

[SCSG-G4]

To thin the motor oil so it is about the same consistency of diesel or JP-8.
