I understand that they are expensive but due to their design, they reduce drag on the water surface, increased steering is something else and by design increase fuel economy drasticaly. As I have a lot of interest in the product (and so do several of my clients) who is the local Aneson Distributor in the Seattle area? I have been reading up on the Aneson Surface Drives.

Motor oils have sulfer in them. When mixing sulfer with the moisture in the crankcase, creates sulfuric acid in minute amounts. In pleasure craft that sit for months with that same sulfuric acid is sitting on the main and rod bearings slowing eating away and pitting. In the old days, it was reccommended that the oil be changed in the engine every six months to prevent the damage caused by the sulfuric acid. The question is.....is this still the reccommended procedure? This brings up another topic of low sulfer. Motor oils have sulfer in them.

The engine life of all three have been good. The owner, Al Utter told me he got 40,000 hours out of the 4B. I changed out the injectors on the main at 11,000 hours, which isn't bad life. I'm wondering now if motor oil is also low sulfur like the new fuel? The engines on the Sierra Seas are all Cummins: The main is an 855, then there’s one 6BT gen set, and another 4BT gen.

This was probably due to lack of filtration and the acidic level of the used oil. With the new low sulfur fuels the acid level may not be an issue and with the filtration to 2 microns It sounds like a possible solution to waste oil disposal. Have you talked to the Captain of the Southern Seas to see how it is working out for him in the long run. Any long term issues with his injection pumps or injectors?

The waste oil then went directly into his 2000 gallon fuel tank and mixed with the fuel-which his engines burned. I wonder if the filtered waste oil could improve the lubricity of the fuel?

The only additive that I have personal experience with is "Marvel Mystery Oil". It is an old product that seems to improve lubrication in oil, diesel fuel, and even gasoline.
