cooking oil
Hi all, has anyone heard of putting cooking oil in the tank of a diesel to reduce emissions for a MOT??
I have'nt just wondered if theres any thing in it.
Cheers

It is to reduce fuel costs not reduce emissions ----- works for most older diesels but with common rail diesels you have to investigate before doing
it how high a percentage cooking oil is safe for your particular engine.

Hi, you need to check your specific car before doing this.
Someone where I work use to put cooking oil in his car. Killed the pump quite quickly.
It seamed on his model they used two diferent pumps depending upon which supplier they were using at the time.
His was the wrong one.
I use to havw a Shogun and used the oil before the prices shot up. With them the 2.5 was ok but the 2.8 was not.
If I remember correctly the emisions are better on chip fat but not much. It was more a money thing when fat was 40-50p a litre.

I believe some transport companys use ATF (automatic transmission fluid) as an injector cleaner and smoke reducer but I am afraid I do not know the
ratio to use.

I ran my Bongo bus on veg oil when it was £8 for 20ltrs. When I stopped using veg oil and used 100% diesel, the car gradually lost power and
eventually, wouldn't run. I took the injectors out and had them reconditioned and the recon guy took one look at them and said "You
stopped using chip fat then?". It's a common problem.....

not the ATF injector cleaner myth again
ATF and injectors have both changed alot in the decades since this may have been valid

I run an old Nissan Serena 2.3d, which has happily run veg oil for around 18 months now. It's a twin tank system, so it's started on
diesel then switched to 100% filtered used veg oil.
As a general rule you can run the Bosch injector pump on vegoil without problem - if it's a Lucas pump you WILL snap the mainshaft if you run
them with a high percentage of veg. As BT said with modern diesels you need to do your research - you'll certainly need to at least twin tank
it.

However old fashioned mineral ATF works a treat on stuck hydraulic tapets.

You can get electrical pre-heaters these days --- either the silicone electric pad type that wraps round the filter or the type that use glow plugs
to heat the fuel (!)
Personally I'll just stick to a petrol engine running LPG

If my Audi TDi gets a bit smokey for the MOT test I feed the pump from a neat jar of injector cleaner and run it for a few seconds. Then go out and
try to get as much heat and load in the engine for a few miles to dislodge the muck. Tip from the MOT tester when it first failed and it worked!
