Primrose 405 for summer and 409 for the winter up north.
I buy it here

The problems start when a heat threshold is reached that promotes the breakdown of the sulphur bearing compounds into less complicated easier to form ones that are corrosive and/or caustic.
In internal combustion engines sulfuric acids are formed that the oil has to netralize.The sulfuric oxides are exhausted into the atmospher where they can recombine into other compounds. In extreme pressure situations sulfuric gasses form that are bad for humans and the equipment.

Someone mentioned higher cetane in this thread, and I read it on TDR also. I asked this question over there and never got an answer .......... what does cetane do in a diesel.
Some believe that octane makes a gasser perform better. When in reality that is only in high compression applications where lower octane would cause detination or pre-ignition. Octane doesn't make power, it allows you to make power. But, I have no clue what cetane does in a diesel.
A little closer to the topic .......... I don't run additives as often as maybe I should, but when I start getting a bit of a rough idle or lower mileage, I've found Howes Meaner Kleaner cleans it up quicker than either of the PS offerings. I run 8oz per tank to do this. I should probably start running 4oz per tank all the time.
I need to update my sig, but I've ran the EZ, Quad Race and have a SPDiesel IIe on the way. I've drug a trailer in/out of every state and I'm still on the original injectors @247,000 miles using Howes.

Cetane is a measure of a fuel's propensity to knock: napthalene and n-cetane are mixed together in an ASTM-CFR test engine in proportion to match the knock characteristics of the test fuel.
Unlike octane however, a higher cetane number fuel will knock more readily, since it tends to have fewer long-chain parrafin-type molecules.
Diesel has an octane rating of about 15-25
(don't put it in your gasser!)Higher cetane fuel will make cold weather starting and operation easier, but offers no power-producing benefits by itself. Lower cetane fuel won't hurt a compression-ignition engine, but may prevent it from starting or running at all.
I've noticed a rash of timing-rattle issues lately across the board, I wouldn't be surprised if the cause is the new ULSD, which has higher cetane, 1% less BTUs per gallon, and fewer aromatics.

I've addressed this before - don't know if it was this thread or not...

It's true that biodiesel has more lubricity than dino diesel and that is the problem....orings, gaskets, seals, and seats tend not to seal as well when the fuel has a higher composition of bio fuel....too much of a good thing?
Some older gasket, o-ring, and seal material can be degraded by the increased solvent power of bio diesel. Cummins recommends B5 only currently. ks
