Running on cooking oil

<< < (3/4) > >>

If you run it on old cooking oil it has the fats from the food in it this not only smells like your driving about in a mobile chip shop but it goes solid and blocks the fuel filter in cold weather.Pete

Be careful what you post; although the rules now allow veg oil in limited quantaties for private use I am pretty sure that untaxed petroleum products are still illegal - if not we could all burn red diesel up to the quantity cap.

I am sure somebody who knows more will be along with the proper rules.

Range Rover Ron:
I dont think old Rudolph was involved in the design work for the Tdi engines that LR put in the Discos/Defenders and RRC's.
LR designed their engines to run on Deisel.
Modern engines and modern fuels are specifically designed to each other.

Pete has reiterated what I said about hard deposits from the Cooking oil.

As for getting involved in mixing with other fuels to get it to start or run,
Well I have to be honest and say that I really could not be bothered to go to all that trouble just to save a few pence.
I'd be happeir just going to the local service station and filling up with the proper stuff.

Deisel is it's self designed to have a "flashpoint" at a certain pressure, (the point when it ignites)
All fuels have a different "flashpoints", some needing ignition some combusting under pressure,
Mixing will not only affect the "flashpoint" but could do serious damage to your engine.

I suppose you make your bed and then have to lie in it!

Range Rover Blues:
Fuels for compression ignition engines are rated on their "cetane" equivelent, it's the opposite to Octane.  IIRC reference fuels are made up of octane and cetane, but I may be wrong there.

Anyhoo, AFAIK the cetane rating of bioderv is similar to that of dinoderv, veg oil is a litte lower, but not enough to be a problem provided it atomises properly in the combustion chamber so that it can burn, that's the issue with veg oil as it's thicker.

crazymac:
It all may become a bit academic the way veg oil is going up!!

I bought some 2 weeks ago in Tescos for £2.21 for a 3 litre bottle. Today for the same bottle they wanted £2.98!! [Edited]??? They can shove it, I went and bought elsewhere :evil: :evil: :evil:
