Alcohol, need massive tanks and weeny jets.
Gonna have to disagree here - you need great big massive jets!

I was wondering about modifying veg oil, but it is massively tedious/complex.
As in cracking it or similar? That would be fun...
Gonna have to double disagree, you need big orifices, small jets and massive flow
I would have thought that a transfer between a home tank and a removable car tank would have been the go. If anyone can point me in the direction of the components. Having a bit of a one off car, I wouldn't want some poncy tank. I would use cylinders.
Anyone got any links to LPG equipment sites. I would want something suitable for a blow through supercharger setup? I would be interested in basic components. LPG kits is one of the areas of fuelling I have no knowledge of.

I had links ages ago where a guy was doing just that. He originally used a hand pump, but he also had info about an electric pump, although it was a lot more expensive.
Im sure any gas retailer should ahve info on transfer pumps.
I did search a few days ago, and post some links I found on another thread here.
Not sure what thread it was, but it was to do with gas/LPG.

Rationalising:-
A while ago I had to do the head gasket (1st OHC one) I reckon that something must have slipped a tooth as it was running too advanced which caused it to clatter. This was augmented by running veg oil. Now I have the timing set up properly, it is running sweet, but won't idle very well until hot. I assume this is to do with volatility, being a function of viscosity, I will be thinning is with some "Kerosene" to aid cold starting and give my injector pump a break.
Diesel engines are uninteresting and I haven't given them much thought. The timing issue is curious whether adjustments needed to be made or it was just my OHC idiocy which wrecked it. I can't get excited about cetane numbers.
Oh, and now the timing has been adjusted for it to run sweet, it cains out loads of filth under accelleration when cold and smells!!!
I could really use a U-tube viscometer if anyone has one I could borrow, to actuall pin down the temperature/viscosity properties of veg/kero mixes.

Tripple disagree If you are running alcohol on a carbed engine you will need massive main jets to get enough fuel into the engine. Ethyl alcohol has a stoichiometric of around 9:1, and Methyl alcohol around 6.5:1
BTW some solvents can cause big problems with nitrile rubber fuel lines and the diaphragms in mechanical fuel pumps.
Have I missed a few posts, or is the 106 back up and running again ??
Was the engine damaged or not as you thought ??
A friend has just started running his Kangoo van on Kerosene, mixed with veggy. First drum seems to be going well.
I dd read though that veggy and diesel type fuels dont fully mix, and in the colder weather, the veggy oil can gather at the bottom of the tank ??
Saying that, mate has been using veggy/diesel for some time now. It didnt start too well when cold. It does run a bit better now on veggy/kerosene.

I need a viscometer to get the viscosity right at low temperatures. I will run a detergent as well if there are mixing problems, which I very much doubt. It may be feasible that the oil (if used) has associated water which on mixing with mineral oils would drop its water into a gummy slop. Probably not that significant though.
The injector pump has failed due to excess viscosity due to low temperature and me caining it.
When I can be bothered, I will get a drum of Kerosene and start experimenting. I refuse to do the transesterification reaction as it is total overkill. Got to get my paperwork sorted as well as it is a tad smelly (with good injectors). I assume that having the injectors too advanced was responsible for the excess clatter and complete combustion, now it is retarded a tad, it is quiet but burns incompletely. I'm not sure what the temperature drop per degree retarded from the maximum is, I expect it to be highly significant, hence the crappy burn. I may advance the pump a notch to see what happens tomorrow, whether I can find a happy medium.
It is rather smelly, so smelly that it may be really worth having the bit of paper just in case the cops get wind of it.

I dont think he really means he only does 400 miles per year. More he is suggesting he tells customs that he does 400 miles per year, which is what he will be paying the duty on, as far as fuel/veggy oil useage goes.
Police Officer: 'Let me see your valid MOT certificate... that's interesting, you have done 4k miles since your last MOT'
Good one.

I would expect that the law would manage to shag you, after all, it's motoring related!
When the insurance is up, I'm going to go limited milage as possible and disconnect the speedo and run a bike speedo.
Visualise Pug 106D, white with a few blobs of rust, 180000 miles, value about £200, kept in Fort Knox out in the safe countryside. Purely transport for when the mini is off the road.
Me 28, clean licence, etc, etc. Have always had classic cars with irrelevant NCB. So, what's my quote? £300 and then some IIRC. That is piracy, my bloody mini with unlimited milage/rollcage/etc road going go-cart loony machine only costs me £200!!!!!!!!Fully comp as well. Never used an insurance company apart to request a quote!
I have had it with people bleeding my pocket for their non-services. I'm going for the 1000 miles option and then disconnecting the speedo. I refuse to pay for this legalised piracy. Obviously I have got too much to lose so being uninsured is not an option.

TBH using red is the cheapest option, if you can get it at a sensible price.
Ive been driving a diesel as a second car for about 6 years mostly to get to work and back and general transport.
While I have heard of quite a few dipping operations, I have only came across one myself, although I was in someone elses car at the time.
Generally speaking I do not use my car during work, which is the most likely time to get stoped at a roadcheck.
But red is getting harder to get at sensible prices.
If during that 6or 7 years I had been using red, I reckon I would have saved myself about £15-18K a year in fuel costs.
Of course I wasnt, so I didnt pmsl
I do less miles now, and in my most recent diesel, a cheapy Rover 400, I am now being stupid, and just shop around for the best price on regular diesel.
But I am considering the heating oil option for use with a diesel on private land.

Although most motor insurance companies are making money at the moment, it does go in cycles. They make good profit for 3-4 years, run even for 1-2 years then loose shedloads for 3-4 years and the cycle begins again.
I'm very unimpressed with the service, especially where claims are involved (not me, but friends), but they now have the same loyalty and interest as the buyers who swap insurance companies every year just to save 10 quid.
On top of this, cars are soooo expensive to repair now, whilst they (even new) are comparitively cheap to buy.
If you have an accident and they can prove you've been fiddling the mile-ometer, They'll nail you gonads to the wall (financially speaking), and you'd be amazed at the ways they can check.
Oh, I'm not involved in motor insurance.
