Hi

I run my 1996 405 TD on veggie now and again with a 50/50 mix, when colder 70/30, should I be OK to go 100% without heating etc?

Some have no problems, if you go over 75% you will start noticing it becoming a bit lumpy on cold mornings starts, a few glowplug cycles usually helps. However, i ran close to 100% and came into problems, lumpy idle when hot aswell, the thicker oil makes the pump work harder and can damage seals, when you hear one running on 100% on a sub zero morning you will soon understand why! Many have not had leaks occur from it, or noticed any side effects, but for me the possible expense of a damaged pump/seals needing a rebuild is too much to risk, so i am running 60/40 for now and enjoying perfecting starting with reduced cost, and also much better mpg with this mix than a higher % of SVO.

I'll go to 60/40, any suggestions for best deals, obviously the majors have increased in line with fuel!!! Been using Li*L at present .68 lit.

Info on running on Veg oil here http://www.coupe-club.org.uk/smf/index. ... 244.0.html

The Bosch pump is ok for it as it doesn't use the diesel for lubrication, the Lucas pump is unsuitable as it does, and you will end up with a sheared off rotary head as I did

If it's a 2.1TD 406 then don't let even one drop of veg anywhere near it!

These engines have the brilliant but very delicate Lucas/Delphi EPIC pump and it will die very quickly if it sees veg. It is deadly poisonous to it.

The same applies if it's an HDi.

Replacing a dead EPIC is a very expensive job.

I have, on the back burner, a project to develop a mechanical Bosch or mechanical Lucas conversion for the 2.1TD.

I need a donor with a dead EPIC to proceed.

Veg is only safe in Bosch equipped 1.9TD engines.
