The first vehicle I ran on Biodiesel was a Renault Traffic
with a 2.1 engine, the same as Josh Tickell's Veggievan but without the
turbo. This ran faultlessly, visiting the RAC rally in the middle of winter
and always started well despite the engine being worn out to start with.
My Astra has now covered about 12000 miles since it was bought just
over a year ago. Most of this has been done on 100% Biodiesel. So
far it has been mainly problem free:
The filter life has been reduced to the manufactures recommended interval
because it cleans out any muck in the tank. It clogged up the week
before it was going in for a service!
Cold starts are not really a problem, it's never not started. If it's
frosty then it might need two lots of heat and a little bit of throttle
for ten seconds to warm it all up. This isn't a lot different to normal.
The heater duration and fast idle could be tweaked but it's not really
worth the effort.
The exhaust smell is a lot more pleasant than diesel although traffic
jams can cause hunger pangs when the subtle smell of frying wafts
past. I've quite often seen people wind down their windows and sniff
the air when they're sat behind me.
|The other vehicle I run on Biodiesel is a Renault Extra Van. This
is used as the company runabout and daily transport for John. It was
bought needing an engine rebuild and has run on 100% Biodiesel ever
since. It passed it's MOT smoke test at .75% - the inspector said
he'd never seen anything below 1% and normal higher.
