    In all seriousness, apparently Bio produces much less emissions and smoke than DERV, so even you AD41 users might be smog free [img]/forums/images/graemlins/grin.gif[/img] [img]/forums/images/graemlins/grin.gif[/img] [img]/forums/images/graemlins/grin.gif[/img] [img]/forums/images/graemlins/grin.gif[/img]

    Have we had answers to the shelf-life question in a boat's tank? Also - are fuel pumps okay on it, as I've heard concerns about that raised....

    Don't know about the fuel pumps, I've not heard that there is a problem if it is in a reasonably modern engine (post 1990 ish).

    Recommendation seems to be that 1/2 a tank of derv every now and then doesn't hurt. The main problem with logevity is that Bio will actually absorb water if left untreated over a period of time. Obviously not an issue in cars etc but in boats would be a problem.

    There is an additive avaible which stop the problem, and should be added to 'marine' bio diesel. Does add 3-5p per litre though [img]/forums/images/graemlins/frown.gif[/img]

    Going by the car side of Bio (SVO), most bosch pumps are ok with it, but lucas pumps have problems with the seals swelling and too tight tolerances causing lubrication problems.
    Only other problem as i can see is it might make starting in the winter harder as the bio is a little bit thicker i think, but that could just bo on SVO.
    Tried an Escort van on 90% SVO 10% DERV and it ran no problems, even seemed quieter.

    Biodiesel isn't the same as Straight Vegetable Oil, is it?

    So we have red for a while longer,it would seem,but bio i hope is the way to go.Now need some experts at mercruiser,volvo,yanmar etc to have a serious look,if they want to keep sales up.If some minor adjustments are needed perhaps they could offer a bio conversion pack with manual!!!!

    Volvo reckon that you can use it at a 5% mix only ie 5% bio to 95% road or red? I understand? [img]/forums/images/graemlins/frown.gif[/img]

    That is for warrenty on engines &lt;2 years old. TBH, Bio is fine in the engine to 100%, mine are out of VP warrenty, so they can go hang themselves. Same reason VP main dealers don't touch my boat. They tend to be expensive and cr<span style="color:black">ap</span>

    Can you advise whether your Biodiesel adhears and tested to the EN14214(?) standard and do you have a list of fuel pumps/ marine engines that the diesel will work with.

    Based on the above are you happy to run 100% bio or a mix?

    From a delivery side what are the options and affects on price.

    Looked into making Bio myself, as I could make it pay in 18 months ( price of processor, chems and other equip ), but lack of space stopped me!

    Thanks in advance

    As an example in Germany all pump diesel is 5% bio and 95% dino. 5% is a very safe mix and most likely not going to cause any issues to fuel pumps. I'm no engineer but newer engines run at much higher pressure and aren't good candidates for bio as they will clog up, especially when started cold.

    Older engines and I'm not sure what that means may be capable of running 100%.
