Drawbacks Of Veg Oil Motoring
I often get asked if there are any drawbacks associated with running
a diesel engine on vegetable oil, and of course there are.
Below I've listed these, in no particular order, if only to prove
that I'm being objective. The other pages on this site may make
veg oil motoring appear somewhat idyllic, so I thought I should
try and balance this out by pointing out the worst drawbacks I
can think of. This way, at least, you'll be better prepared should
you decide to take the plunge...
The Obvious Biggy - Costs
It costs money to have your engine professionally converted to
run on vegetable oil. It's not cheap either... think in the region
of several hundred pounds or more. I can't give an exact figure
because I don't fit these things for a living, so contact experts
like DieselVeg who
will give you free advice.
Similarly if you're going to collect and filter waste
vegetable oil, there's set up costs associated there.
You can control this budget more carefully, as it's a DIY thing,
but a couple of hundred
pound may still be required - more if you want fancy filters, pumps,
etc.
On a positive note, once these initial set up costs have been
shouldered, you should be able to recoup your costs and much more
besides when
you actually begin driving on veg oil.
Weight - It's A Heavy Matter...
Whether you buy your veg oil from the shops, or whether you recycle WVO,
you've still got to get the oil into the tank. The chances are
you're going to have to haul large containers holding 15 or 20
litre's
of veg oil around, lifting and pouring with care. These containers
are surprisingly heavy. I'm
a fairly strong guy but I've been known to struggle doing this.
Don't underestimate the difficulty.
Spills and Mess
Sooner or later you're going to spill some veg oil. I spilled
a couple of litre's on my block-paved driveway. I wasn't happy.
Fortunately I remembered an old trick - pour cat-litter on it and
leave it for a few days (take a look at my cleaning-up section).
This trick worked, soaking up most of the oil, but it did leave
an oil
stain.
However,
as
you've
heard
me
mention elsewhere, vegetable oil is biodegradable and sure enough
after a few weeks the stain disappeared.
However it is a messy substance. When it's poured it seems to
hug the outside of the containers, running down the sides on to
your hands, dripping on the floor, making an oily puddle when you
place the container down. You always need to think in terms of
drop-cloths, paper-towels, etc.
If you filter WVO then
you'll really discover how smelly, sticky and messy veg oil can
be. Your clothes will get covered in it and everywhere will become
cluttered with containers holding various stages of oil and sludge.
Forgetting To Switch
Unless you're extremely well organised or have a fantastic memory,
the time could well come when you forget to switch off the veg
oil a few minutes before your journeys end. If the engine cools
and there's veg oil inside instead of diesel, you'll have a nightmare
of a time starting your car. I've dedicate
a whole page to this subject which I suggest you read carefully.
The Bright Side
Obviously I'm a confirmed veg oil driver. I've been doing it for
a few years now. There is great pleasure in knowing that you're
doing your bit to help the environment. Also it certainly helps
save a few quid as well, and that can't be sniffed at.
However, I will confess, if any local forecourt starts selling
vegetable oil at the pump for half the price of diesel, I'll be
a very happy man. I'll give up filtering WVOand
enjoy the luxury of convenience.
