Hi Rick, A friend who works on cars and has a 32 foot sailboat for 25 years that looks better than new, suggested I use SeaFoam in both fuel and engine oil. It's inexpensive and seems to make starting much easier, so I've been using that for the last 8 years. I use Bio-Flo Jr when I top off the tank for winter. Any thoughts on SeaFoam?

All diesel is made to the same set of standards. The red stuff just has a dye in it to indicate that the highway fuel tax has not been paid. When your engine was built, diesel fuel had 5000 parts per million of Sulphur content. The Sulphur was a significant factor in lubricating the injection pump, injectors, etc. In the mid to late 90s, in anticipation of the Tier 2 emissions standards, Low Sulphur diesel became mandatory. Sulphur content was reduced to 500 PPM, and lubricity additives were incorporated in the fuel. In the middle of the last decade, in anticipation of Tier 3 emission standards, Ultra Low Sulphur diesel became mandatory. Sulphur content on current fuel is 15 PPM. A new Tier 3 engine is designed to run on ULS fuel, just like a new gas engine is designed for ethanol. Yanmar, Cummins, and Perkins (the 3 brands of diesels I used to teach technicians about) all recommend that you add a lubricity additive to your fuel if your engine was built before Tier 3 and ULS diesel became the norm. For our size engines that means about 2010 (1 year later in Canada). The service bulletins from Yanmar and Cummins (which I unfortunately lost when the laptop’s hard drive went up in smoke) both specifically recommend the additive from Stanadyne. Even though my Universal M35B is a Tier 3 version, I still add Standyne lubricity additive (although I do occasional use a product from Lucas). It can’t hurt. I also put BioBor JR in the fuel as an algaecide and try to keep my tank full during winter storage. As Josh said, the nasties live in the water in the tank and eat the diesel (don’t get me started on bio-diesel). An algaecide and reducing the chances of condensation in the tank are good policy for avoiding fuel filter problems. I’ve used about 2 tanks of fuel this year, so I’m not concerned with the duel degrading in storage like you get with ethanol stored in a boat. Diesel can generally be stored for about two years without significant degradation. Rick Brass Washington, NC From: CnC-List [mailto:[email protected]] On Behalf Of Richard N.

With apologies for re-raising a previously discussed topic; my boat is a 1985 37 with the original Yanmar 3HMF 27 hp; I went for my annual diesel fill up and the pumps were out of order; so I had to get diesel from a street gas station; although the cost was almost a dollar per gallon cheaper, I noted that it was the "green" color rather than the "red" color; so my question is do I need to put some type of sulpher additive or something along those lines into this fuel? I did motor with it for an extended time on Sunday with no adverse effects; in addition to this question, what should I use for the upcoming winter layup? many thanks Richard 1985 C&C 37 CB; Ohio River Mi. 584; Richard N.
