Additional Lubricity

[NHgranite]

Which additive is best for improving lubricity? I'm not concerned (as much) about any other properties.

Background info; I'm running Jet-A in my ALH.

Thoughts/suggestions/tips?

I use Stanadyne Lubricity formula in my TDI.. Stanadyne has been designing and manufacturing Diesel Injection systems for years. They seem to understand what is needed for lubricity for long system life, and make a good product. They only sell through dealers though, but you can buy it online.

Nothing is better at improving lubricity than a biodiesel concentration of 2%.

Isn't Jet A kerosene? You should quit using it now that the weather is warming up.

Not sure about lubricity issues, but I use B5 just to be a bit "greener". When I can get ATF at a cheap price at estate sales, I buy it and put it into my tractor diesel. Used to put it into the 240D's tank but am leary of putting it into the TDI's. Don't think ATF has much additive, as it's the most highly refined of any lube oil (used to work in the lube oil industry; any ATF distillate we didn't need was diverted to diesel; also know how refined it is). Probably only has a bit of seal swell additive.

No that is Jet B

Thought - run diesel fuel - it's what your car was designed for.

This.

2-5% biodiesel would get it at desired lubricity level and if you can't do that, do what I do on my 06 diesel, I add about 8 oz of low ash 2 stroke oil to each tank with 3-4 oz of diesel kleen.

B2 is the way to go.

No that is Jet B

They are both essentially kerosene. B is merely cut just a tad tighter on the high end to keep the freeze point lower, for cold weather use. Think D1 vs D2.

Neither is suitable for long-term use in our cars without the lubricity help, IMO.

I don't know if it is old news or not, but for those of you who are using biodiesel for lubricity, please read this. The important paragraph is the last one before "Let's Review", which states that only soy base biodiesel is shown to increase lubricity. Any non-soy based biodiesel is a crap shoot without additives, which need to be added at the distribution site.

I would like to take credit for this link, but can't, as oxford_guy provided it in another thread.

Tim: what's the sulfur content of Jet A? Do you know?

Here's a graph that seems to contradict the above statement. The graph below shows that Yellow Grease, Poultry Fat, SoyBean Oil and Cotton Seed Oil based blends at the B2 level yield about the same lubricity benefits. I have yet to see any studies where the lubricity of "non-based SBO" feedstock is a crap shoot and that SBO is the only feedstock that increases lubricity."

The author of the above linked article works for an additive company (bias maybe).

Golfer,


Thanks for the information. I'm not an expert, obviously. "Crap shoot" is my interpretation of the paragraph I was referencing, and it seemed appropriate.

The spec is .3% max. Of course, it is going to vary....only your COA knows for sure!

I should also point out, for anyone not reading carefully....the OP has an ALH.

No amount of lubricity help is going to make Jet fuel ok for any 2009 or later VW (because of the S).
