Each time I fill up with this new Ultra Low Sulfer Diesel, is there an additve to bring up the sulfer content or add a lubricant? Is there a motor oil to add to the fuel?
no use only what the car maker suggest . but sta-bil is good additive
As I mentioned in my answer to your other question, the fuel makers add some biodiesel to improve the lubricity and cetane of the product. It seems to work just fine.
Marvel Mystery Oil, this is a must if you have a 98.5 -02 Dodge Ram. The VP44 is a very precise Injection pump and needs a polymer based lubicaten or the rotor inside of it frys and your 1600$ injection pump becomes a paper weight, w/o proper lube. Marvel Mystery Oil is the best for increasing your lubrication. It's cheap and easy to find too. When ULSD first went into affect my dodge wouldn't do much more than idle until I started using Marvel, it pretty much won't run w/o it if that tells ya anything about this aditive. ATF seems to do a good job on the older dodges, but not the 98.5 on up. It frys Injection pumps. If you want a good cleaner Seafoam works wonders. I've ran pure biodiesel B100 multiple times and it works as well. But hard to come across. Biodiesel with Marvel is a perfect combo. Your injection pump uses diesel fuel as it's lube so it is critical that you have proper luberication
