Anyone use old oil as fuel.?

Sutol · Dec 28, 2011

In these hard times and with Diesel now at over $2 a litre I have been using alternative fuels in my vehicles.

I have been using a 50% mix of old cooking oil and diesel mixed after filtering.

I have also tried old sump oil mixed at 25% with Diesel and also old hydraulic oil.

The engines have less diesel knock and are up on power, admittedly there is a little smoke but only under load so not a problem.
I can use old cooking oil legally but am limited to the amount, its enough to cover 15 to 20k per year in my car or Land Rover though so not a worry, just have to keep a diary of how much I put in and when.

Sump oil is ok but I have to clean the fuel filter regular as it seems to gel in there and block the paper element.

Any one done this or is diesel still cheaper than cheap wine over there.

Just some fun, we need to due some translating.
Do we remember when you had a break away colony that wanted to retain the Gallon measure. Then the Imperial Gallon was developed. This is published in Wiki.

4.54 L = 1 Imperial gallon
3.78 L = 1 US Gallon ( aka old british gallon )

Then we had Metric.
So the Scandinavian Gentlemen that developed the temperature scale had

Water freeze at 100 degrees C
Water boil at 0 degrees C

The scientific community had the scale inverted to

Water freeze at 0 degrees C
Water boil at 100 degrees C

Sump oil ?. In machinery we use a term dry sump when the vehicle is used in extreme off road conditions and the engine oil is returned a storage sump for re pumping
and in airoplanes.

Mostly we have crankcase oil. The gasket for the crankcase is known as the pan gasket.

I watched a TV show about Bio Diesel but there can be some problems that do not come to mind at the moment.

I watched a British Telly ad ( Utube )about Cataclean that you add to the petrol to help pass the MOT test. I am looking for a Canadian equilevent.

I would love to buy a diesel Land Rover, but in this country they are rare even running on GAS.

I just recieved 6" of snow and the temperature is - 12 C. ( mixed standards )

If I am not totally wrong I read that Clessie Cummins designed his engines to run on something like 50% oil. If I don't use my spent oil to burn brush piles I burn it in my older truck. It will add lubrication to the thin-as-water new "low sulfur" fuel.

I use it to help heat my shop.

Since I don't get 44 qt.s from an oil change any longer, I've had to chop a lot more wood

I used 25% used old engine oil in the land rover last year and it was down to -20 some nights, the motor started a bit lumpy but soon cleared and was fine.

I put the odd gallon of petrol in now and then to help clean the injectors, its an old land rover so it doesnt have a cat.
The 1990's diesel land rovers over here had a soot collector that looked like a cat but was just to stop bursts of soot when booting it hard.

As for the american gallons I cant understand how a diesel car can get 60 mpg on an American gallon.

I get 35mpg from the diesel land rover and more on a run but that is a uk gallon and uk miles. I find that excellent for a vehicle that weighs almost two tons.

My son has a Renault Clio 182 cup and we have removed the cat, we also removed the cat from his Lotus Elise as they strangle the power

Most cats are useless over here as people only do short journies so they never work as they dont heat up quick enough so what is the point?

I use anything that will burn in my 17 year old Peugeot 309 turbo diesel and have done for years, not been a problem so far and its done 160k so not really worried.

Diesel here is $3.49 cents a Gallon...Gasoline just jumped to $3.15 a gallon. I bet you have at least a 5 micron filter for your fuel and used crankcase oil? Particles into the fuel injectors and the fuel pumps would be the main concerns?The fuel injectors on my 3 liter Mercedes were very tiny, but a friend just filtered cooking oil into his 2.3 liter and it burns it?

I filter down to at least 5 microns I'm not sure but I think the filter is 2 microns.
Older diesels (clunkers) will burn it no trouble but the new high pressure injection systems will not. The new cars may even shut down when they detect 'black' diesel coming through.
Mine is just an old mechanical fuel pump system and if it will go through the filter and it will burn then the engine will run
