A friend showed me this link which I found to be interesting, wondering what folks can add to the conversation.

I feel compelled to use additives to take care of lubricity, but there are issues that come up:

1. Extra cost per tank. I find myself using too much PowerService because I am haphazardly just dumping some in on each fill. I know I end up using too much, which does nothing to help matters.

2. Summer/Winter issues. Would like to use biodiesel as my lubricity enhancer year round, but it doesn't seem prudent for winter use. I end up using PS in the winter and Bio-D in the warmer months.

3. I have read on the forum that some folks feel like using bio-D releases particles in the fuel system that clog fuel filters rapidly. I remember someone recommending to ease into the use of bio-D by slowing raising the percentage run over time.

4. The test only used one type of Bio-D. There must be different levels of biodiesel fuel quality. Opinions?

It sure seems like plenty of folks on this forum use PS, though it scored somewhat poorly on the study. Does this change any minds? I can't help but feel that Bio-D ends up doing a great job to enhance lubricity, and is cheap.

What do y'all think?

 

It only takes 1% bio to raise #2 diesel lubricity 80%.
More than enough from a only third of gallon of BD per tank.
BD has a solvent effect that will clean out deposits in your fuel system.
The solvency is determined by the percentage of BD, most people report little problem with B20 (20%) as the cleaning job is slower. Higher percentages speed the cleaning and can clog the filters faster than your normal change interval.
All this can be monitored with a cheap and easy to install fuel pressure gauge.

If you are concerned with lubricity and want to avoid gelling use 2 cycle engine oil instead.

Personally I feel there is absolutely no lubricity problem with P pumps and the current ULSD (Ultra Low Sulfur Diesel) and use no additives except for antigel in the winter.
Federal law is all diesel fuel must have the same or more lubricity as it always has. ULSD is no exception.
I feel any problem is way overblown and mostly rumor.

 

Why Super Tech Outboard 2-cycle TC-W3 harm a 2007 ?

 

I don't see how. I wouldn't get carried away with it though.
One quart per tank should be fine.
