Which Engines/Fuel Pumps can handle Vegetable Oil Mixes?

[gavin44]

Hi All,

I wanted to collect together a difinitive guide as to which desiel cars can handle SVO or filtered WVO mixes. However I know s0d all about VW engines.

I'll start us off with some Rover details

Rover

L-Serires Engines:

all 600's - all direct injection - use Bosch VP37 fuel pump
200-400 post 96 bubble shape. Di models are direct injection with intercoolers - also use bosch fuel pumps that seem to be tolerant of veggie mixes - but beware of the 25/45 fuel pumps (VP30's I think) - they don't seem to be as resiliant.

Audi's

Please correct me if I'm wrong - but aren't the A80's 1.9 TDi's 91-94 quite tolerant of a veggie mix?

Ok - that's for starters Hopefully we can get a difinitive guide for all to refer too...

Kind Regards,

Gavin

I'm just about to convert my VW Golf Mk5 2004 GT-TDI 140PS BKD (a mouth full) to run on Veg Oil with an (expensive) kit from Elsbett.

It looks like PD engines must pre-heat the veg-oil to at least 70degC before you attempt to feed it into your engine otherwise you will cause all sorts of problems with gumming up of your piston rings and jellying your oil during the warm-up phase.

I've put a few tanks of 50:50 mix into the car and although it ran ok once warm, it took a few starts to get the engine running from cold... this is one of the symptoms of bigger problems around the corner.

Another thing is you will have to forget about long life service intervals and stick to regular oil changes, both of which I'm not too bothered about considering the money I'll save in the long run.

Therefore, currently it looks like a dual tank system is the order of the day. You take your spare wheel out and pop a tank in there for the veg-oil. Then it's a matter of wiring in the extra fuel pumps and plumbing to the front of the car with the changeover solenoid valves... all very exciting!

Apparently, Biodiesel is a no no in PD engines, so don't even try that.

I think what I've put sort-of describes the basic procedure in nut shell.

When my kit arrives, I'll put together a small tutorial on my web-site explaining how I fitted the kit.

RME fuel (biodiesel)
RME fuel may only be used in vehicles which have been approved by Volkswagen for this purpose with RME fuel - either in the standard version or in vehicles with optional equipment (PR number “2G0”).
The PR number “2G0” on the vehicle data sticker indicates the RME compatibility.
For vehicles with standard diesel particulate filter (DPF) RME fuel (biodiesel) must not be used.
Caution
When RME fuel is used and your vehicle is not suitable for this, the fuel system can be damaged.
When filling the tank with biodiesel, only use RME fuel conforming to DIN EN 14214 (FAME)!
When biodiesel is used which does not conform to the required standard, the fuel filter can become blocked.

RME fuel must conform to DIN EN 14214 (FAME).
RME means “Rapeseed Methyl Ester”.
DIN means “German Standards Authority e.V”.
EN means “Euro standard”
FAME means “Fatty Acid Methyl Ester”.
NoteThe RME compatibility of the vehicle can be identified by the PR number “2G0” on the vehicle data sticker. If the vehicle is not factory fitted for biodiesel, the PR number “2G2” is indicated on the vehicle data sticker and a note “Not for biodiesel!” is found on the inside of the fuel tank flap.
