I've made biodiesel for about 3 years and I have run Mercedes E300's and Discovery 300 tdi's on it without a problem. I couldn't resist this good condition Patrol at the right price, and to be honest I had been running on bio for about 3000 miles until it suffered from the dreaded hot start problem, which has cost me a fortune to get fixed, the diesel pump mechanics blamed it on the bio, which I believe had nothing to do with the problem, but they were so damning it has rather put me off using it.
I have researched the Zexel Kiki pumps, and as far as I can tell they are compatible with bio and it's not common rail, so no problems there either, so I reckon I should go back to plan A and start running on bio again.
Thanks for the comments so far, I look forward to any wisdom or experience that you can share with me.
