MMO, IMO, is a fine fuel lubricant. Not better than anything I've seen that can be proved, but it's formulated to be mixed and burned with fuel. A dedicated lubricating fuel additive may be able to do more with less (additive and dollars). Also, IMO, 2-cycle oil may be a better alternative, especially in LBZ engines, as it can increase fuel viscosity, which helps the pump's ability to build pressure (read: P0087). 2-cycle oil is also formulated to be mixed and burned with fuel, and may result in less negative residual combustion properties. I've been using it for over 100K miles (as well as Power Service). I recently changed a bunch of glow plugs and all of them showed zero fouling or abnormal residue. The plugs haven't been working for at least 20K miles (more on that later), so the residue should be representative of the combustion chamber in general.
The main ingredient in MMO is mineral spirits.
Dmax, is the 2 cycle oil a synthetic or a bean oil??
I use Super Tech (Walmart) brand. It's TWC3, rated for liquid cooled engines. I don't believe it's castor oil, and I'm sure it isn't synthetic (too cheap). In my experience with high performance power equipment, a synthetic blend is better than either synthetic or veggie/mineral alone, but I seriously doubt synthetic has any advantage in Diesel engine fuel, so I suggest cheapest is bestest.
Thanks...
Just put a REAL fuel treatment in with a real lubricity additive already.
I so agree... On a treatment cost per gallon basis, the real stuff (genuine diesel fuel treatment with lubricity additive) is usually far cheaper too. Plus, if the diesel fuel treatment also contains a cetane improver, that usually improves fuel economy enough to pay for it.Quote:
