HO HUM totally legal and NO TAX to pay if you drive less than 20,000 miles P/A I run my Fiat Punto TD on VO generally Rapeseed Oil (AND it has a rotary pump) 100% successfully - run with 20% /50% pump diesel in the winter. The car is TOTALLY as it came out the factory NO mods and has 150K on the clock. One of my friend who is in the RAF runs his MB 250TD on Jet Fuel just sits the car under a Tornado or Nimrod for an hour or to to fill the tank :-( TD is touring Diesel BTW not Turbo no room for a turbo on RHD cars booooooooooo hoooooooo

I've now been running for about 2 weeks (1500 miles) on 50/50 straight veg oil and diesel in my 940 24TD. This morning it was a bit hard to start (at 5AM), it would fire on the 1st stroke and would then die within a few seconds. This happened about 5 times before it ran smoothly. This was the first morning I've had to scrape ice off the windshield though.
I'm still waiting for my Elsbett single tank kit to arrive from Germany, which should allow me to run on 100% veg oil, unless the temps get down to well below zero in which case they recomend going back to 50/50.
Other than this morning I haven't had any other problems yet and as for long-term damage only time will tell, but I'm willing to risk it.

Hi, As for as I know, the 6 cylinder 940 TD is a 6 cyl vervion of the old 4 cyl 1.6 VW Golf Diesel. It has no issues running on veg oil. As other posters said, watch if air temp is low enough to solidify the veg oil.

great page with lots of good links if you dig it says TDI is ok with SVO so long as you heat the SVO.....mmmmmm

Hi,

I've just got a '91 940 which will be run on veg oil when I've sorted a few other problems and found myself a 'baseline' to work from.

Previous to the Volvo I ran an '99 Escort on a veg oil mix varying from 50/50 to about 25/75 at max. The car came with a Lucas rotary pump, which have a very bad reputation on veg oil, especially when cold. Initially, got an ATG 2-tank kit from Dieselveg in the UK (Wolverhampton. Very helpful, would recommend). The idea is to start on diesel and then swap to veg when warm.

However, I ended up converting the engine to use a Bosch VE injection pump, which have a very good reputation on straight veg oil when cold. Although, when the weather gets really cold it's advisable to add a little unleaded petrol to help the pump by reducing viscosity and acting as a combustion aid.

One of the critical aspects of running on veg oil, is to make sure the engine gets hot and stays hot. A cool running engine will prevent the veg oil burning properly, and consequently ring gumming and unburnt residues are the start of merry pathway to engine destruction. Imagine, your frying pan when the oil isn't hot enough, it will adhere to the pan as sticky gooey mess.

If you are running veg oil, watch your oil level very regularly. If veg oil is leaking past your rings (as they may be worn or gummed up), it will mix with the engine oil which causes the level to rise. The real downside is the fact that as it mixes with the oil, it increases the oils viscosity to a point where it will become jelly like and hence be un-pumpable, which will starve your engine of oil.........

I started collecting old fryer oil, and am assembling a filtration set-up using 10" spun polypropylene water filters. The biggest issue is removing the water from the used oil, it can be heated but I'll try a water separating fuel filter first.

Of course, new veg oil or pure plant oil (PPO) doesn't seem to have this issue. However, a lot of people who have far more experince that me will recommend running through extra filters.

Have a look at :

They have a fantastic forum, with some very knowledgable people.

Bye for now,

I've read it's advantagous to use engine oil made from veg oil if you are using Straight Vegetable Oil as fuel, as it's less of a problem when the engine oil gets diluted with fuel oil getting past the rings. Wonder if it smells like Castol R? That was so nice.

Dieselveg in Wolverhampton sell it.

And also a brilliant induction heating unit for injection pipes.

easy to test for take a sample out of the engine and pop it in the fridge watch out for SWMBO and you can test for jello if that works fine then pop it in the freezer for a while might be a good idea to do a back to back test with two samples together new oil and out of the engine oil at the same time so you have an instant comparison

Expect to sleep on the settee though when your wife fries her chips in it while you're out in the garage.

BE BRAVE tell her what you are doing :-) you can bribe her with the fuel savings

Tell her you've put used engine oil in her fridge!!! Thats even worse. You really must be a complete Volvo nut to think you can get away with that without going unpunished.
