Just found a local supplier of bio diesel.Running @ 50/50 mix at the moment and the LC seems to run fine,the only problem so far being the smell of the exhaust maked me hungry! The guy selling it said I should be OK to run 100% bio (it's from fully refined/recycled used veg oil).I know there are several people on this forum running bio so I'm just curious about any adverse affects of running bio that you may have come across.I know about changing the fuel filter after a couple of tanks,thinking more about any fuel pipe/pump seal leakage issues here.

Cheers

Bio fuel is like brake fluid in that it absorbs moisture from the air, I would advise fitting a water/sediment bowl into the line from the tank, also engine oil changes should at least be halved to about 2500 miles, I'm very sceptical of the bio-fuel issue, also beware of a build up of algee in your fuel tank , they look like a black jelly. We have Tier 3 tractors with common rail engines that will run 100% bio , but power is slightly down as is specific fuel consumption, if you take into account the cost of the extra oil and filter changes then you have to be doing a lot of miles to make it pay, also older FIPs are prone to developing leaks as the fuel attacks the seals . Only my opinion, and many swear by various concotions of diesel and veg oil, if you going to use 100% bio make sure its produced to a recognised repeatable standard.

Good produced biodiesel is better for your engine as lubrication is better than mineral diesel, unfortunately the quality of biodiesel varies. YOu can however test it yourself quickly if you have good biodiesel by taking a jar half flilled with water, fill up the other half with bio and close the lid. shake it and if you have good biodiesel the water and oil should separate within 1 min. the oil must be clean and clear, if not.... dont fill up.
