Veg Oil for pre-MOT clearout

Just read on another post about a putting a bit of vege oil in the Bongo to give a bit of a clearout before the emissions test but before I bung a bottle of Tesco's finest into my fuel tank, could someone take me through this step by step as I am sure there are a few details and caveats that may help other forum members too
Have always used Redex in the past - but willing to try anything sensible which my "imaginary friends" (as you have become known) suggest to keep my Bongo healthy.
NB Did a search for this as am sure it must be here somewhere, but obviously using the wrong search terms (again)

I'd bung about 10-15 litres in (if you haven't used it before) when it's down to less than half a tank, then top up with diesel to mix it in, that's it really.

Good lord, that's a lot of vege oil (about the same amount as my mother in law uses for cooking in about six months

).
Thanks Kirsty, I'm glad I asked - wouldn't have guessed that much at all.

It's not an exact science ,other people may recommend more or less

Sounds a reasonable amount to me

- then thrash the nuts off it for a mile or two (Italian tune-up)

Alison that is just a blip of oil, lol, considering I use 30 litres at a time and have done so for the last seven years, especially before the mot, which the bongo has flown with not even an advisory. I make sure she is warmed up before the test and just go for a spin. Good luck.

never bothered at this years MOT.....never thrashed it before either...... sailed the emissions test no probs.....
mind you...now I have stated using Veg oil it has got to be a run up to see my pal and put the Bongo on his emission tester to see the difference now

Just a silly question but if you give the Bongo a really good warm up and a good thrash before going in for an MOT if they then don't test for a few hours will this make a difference?? - I have yet to put any veggie oil in mine and it passed it's last MOT with no bother.

It should be fine Aitch, as long as it's had a bit of a run beforehand to blow out any crud, you'll only have an issue if it never gets a decent blast, which is a danger if you normally drive quite sedately & economically, every diesel needs a blast every now & then.

if you dont fancy veg oil
then an injector cleaner adative might help
but a good run before should be all it needs

As this isn't my first diesel, I'm used to the thrashing bit. I've always hated it but I really don't think I can do it to my Bongo

Will have to try very hard to pluck up the courage.
Most fun I ever had was "racing" a hearse down the Camborne bypass. The driver was obviously doing the same thing. Maybe I should ring round a few funeral directors and see if anyone else is going for a burn and have another "race". Will take my mind off what the thrashing is doing to the engine
