Hi Andrew,
Couldn’t find my
documentation on the octane of LPG but if i remember correctly it’s more then
100. As LPG is richer then the richest petrol commonly available on the market,
the engine will get a bit hotter. On some cars you need to put in harder valves
but that’s not necessary in our boxers. You could change the ignition
timing but the differences between petrol and LPG differ depending what rpm
your engine is doing. So on one point you should put it earlier and another
point later.
If working with the old venture
system your car’s top speed will decrease with 5 to 10 percent because it
can’t get enough air. If you use an oversized venture there will be no
power loss, on the contracy, you might get a light power increase. As to
consumption the increase with the venture system is about 10% with LPG. But then
you’re driving very environmentaly friendly. Apart from that, at least
here in Belgium ,
it cost only 40% of the price of petrol. Here in
Belgium we pay
about 1250 euro for a venture system.
I think one can also run
a DJ of MV on LPI. That way there is no powerloss at all and it won’t use
more LPG then petrol either. These installations cost about 2000 euro over
here.
One thing to keep in mind
is that, because of the engine getting hotter, it’s not recommended to
drive a long distance at full speed heavily loaded (unless you cool the oil, and
add a diesel fan for hot countries instead of the “small” petrol
fan.
Another remark, there’s
a huge difference in biodiesel and vegetable oil. Best for nature is pure
vegetable oil, you know, olive, sunflower, or whatever they are selling at your
local supermarket. You can even burn waste frying oil, beg for waste at mc
donalds (don’t forget to filter used oil though). One big disadvantage :
you will feel hungry all day when you smell your exhaust, it really smell like French
fries (which should actually call Belgian fries but that’s a bit off
topic) Not all l veggie oils smell like fries though, you can do some
experiments to find your favourite perfume.
In summer, autumn and
spring you can pour 100 percent veggie oil in your diesel tank, in winter depending
on your local climate off course, maybe like 50 %. All you need to do is
installing a relais on your diesel pump that heatens the veggie oil. I have to study
that part a bit still J
Biodiesel is something
else, they start from vegetable oil but then it passes a whole chemical process
(which is not so environmental friendly) and then you can use it on most cars. Modern
TDI’s are way too complicated to run on pure honest veggie oil. That’s
why they came up with this biodiesel. We however, driving nice old 1600TD’s
don’t have to use this alternative for vegetable oil, we can burn the
pure stuff J
One more thing, when
Diesel invented the diesel engine, diesel didn’t exist yet. Mr. Diesel
designed his engine to run on pure vegetable oil. It was only later that the
oil industry came with a lousy alternative fuel for vegetable oil, …. Diesel

Re: Syncro Tour 2008 ? And LPG.
Hi Brian
I think the only conversion at present for the TDI is bio diesel??
Cheap conversion to as u dont need to change anything according to the
Myth Busters.(SBS)
Wondering what is Octane rating or LPG? I have thought that the gas
option/conversion may not be so good for T3's as the octane rating is
lower and i think it takes 1.5ltrs of gas to get the same mileage as
in 1litre of petrol??
