Anyone run Bio or Veg oil on here?

Mixing petrol with veg oil is not false economy. To thin veg oil you can heat or mix with petrol. Yes, combustion is slightly wise with petrol but using a cetane enhancer like veggiboost restores the power to that of standard diesel.

Also, it is cheaper to use petrol because thinking with diesel would take say 50% diesel or 15% petrol - which is cheapest? Petrol is only harmful to a diesel pump because it is too thin to lubricate it. Mixed with veg oil it becomes the same thickness as diesel.

I kno theory says don't do it, but please have a read on the forum - practice shows it works very well, even in winter!

With a mix like that it must get right hairy trying to work out how much excise tax to pay on the veg...wink, wink, nudge, nudge.

There is no excise to pay.

In UK we have an "allowance" of 2500ltrs per year of vegetable oils that you can use as a fuel without paying any tax. Mixing with a solvent is illegal, unless fuel duty has been paid on it - therefore if you mix with petrol or pump diesel that is perfectly legal because you have paid fuel duty on it. I promise there is nothing illegal about what I am doing, I have read up on this well and can post the HMRC documents if you really want.

Well I hope you know I was pulling your leg. I'm from the UK and if there is a way you could pass under the nose of "Big Brother" I would secretly approve :-)

I have heard of people buying their veg at Tesco's and using it as a fuel and being in trouble for it.

Here in the US there are no taxes on veg fuels and in fact there are tax incentives for biodiesel and alcohol fuel use.

There are several forums for veg use and they all recommend heating the oil before running through the injection system, especially on a cold engine.
Of course there are many too that believe that their own personal concoction is best.
Personally I use 100% veg oil in heated form, with a 2 tank system, starting and stopping on normal fossil diesel.

Sorry mate didn't realise you were joking with me...hard to tell on a forum - normally people who don't understand assume it's illegal and wrong without checking!

I understand what you mean about heating it, I am going to fit a heat exchanger but that won't help cold starts. I know what you mean about people saying they know best but haven't really tested it thoroughly enough to know for real. There are guys on the forum who run 90/10 veg/petrol all year and many have covered 50k+ miles with no problems.

I have heard about people getting in trouble but usually just unknowing cops getting involved. Or allowance had only been in place for a few years...before that you had to pay duty on every ltr of veg used.

I guess you must be quite young then to not be familiar with the Monty Python skit, otherwise you would have cottoned on immediately. Ask an older person about nudge, nudge etc. LOL

Keep up the good work,

True, I'm 26 so Monty Python was around before my time - but I do know the skit you mean!

Just an update - from an empty tank I tried the mix of nearly 10ltrs filtered/dewatered wvo; just over a ltr petrol; and a couple of cap fulls of "veggi-boost".

Car starts early mornings (2-3 deg C) with frost on the windscreen perfectly fine - no hunting/spluttering like it was on 50/50 SVO/Diesel. Also, it's so much more responsive than on standard pump diesel, I couldn't believe it last night. Seems more responsive hot and cold, and when it's warmed up seems to have much more power and turbo spools better aswell. Crazy!
