Having aquired my first diesel was wondering if anyone has experience of using Bio Diesel?

My local garage sells it & is approx 25p/litre cheaper.

Any thoughts on suitability for an 07 TDV8?

Just use red diesel instead. It's the same as normal diesel but with a red dye.

No-one is going to suspect you as you'll be driving in a premium Range Rover anyway.

Apparently, this is what I've heard....

Go buy some 'gas oil' (another word for Red Diesel), fill up some jerry cans that you have in your boot. Do not exceed 99 litres otherwise you'll have to register your details/business etc. Anything below 99 litres is acceptable and no questions will be asked.

I've been told it is the same as ordinary diesel and makes no difference to your fuel economy or engine at all. The only difference you'll find is in your wallet with upto 50% saving

Apparently biggrin

Apparantly, this is what I've heard....

No no no. What you do is get an old Oil Drum, bolt it under the car, and this becomes your "real" tank which the Engine runs off. However leave the "proper" fuel tank in place, filled with real Diesel, but not connected to the Engine. This is incase VOSA test your fuel.


If that makes sense.

Don't risk it. Bio diesel is substantially more viscous than ordinary diesel and will need an extra fuel filter along the fuel line to filter out the extra material that bio diesel will carry.

I've sold thousands of in-line fuel filters for this very purpose. One man I know has 3 in-line fuel filters on this Peugeot 406 2.0 Hdi diesel along with the regular fuel filter.



It's not really worth going to all that trouble on such a premium car. The cost of fitting the in-line filters will be a major hassle as well as I believe the Range Rover has the fuel filter built into the fuel tank so it would require draining the tank, removing it, fitting extra filters, re-attaching it etc etc etc.

I like your way of thinking.

However, I doubt anyone will pull over a £70,000 Range Rover on suspicion of using red diesel. Plod normally reserves that privilege for taxi drivers, older diesel cars and 'dodgy' looking sorts.

All the fuel checkpoints I have come across seem to go for transits or builders vehicles. Never seen civilian cars stopped, not even a taxi, but it may just be what they were targeting that particular day.

They also lift the bonnet and check the fuel line, so for the underslung covert tank to work you would also need a secondary hidden line to the injectors.

Far better to just get a cheap banger that you can afford to let go should they impound it.

Not knowing the inside of the RR's Engine bay, how hard would that be? Could you run it from the Tank, through the Bulkhead and into the Engine that way out of sight?

On my 330D the fuel line from the under bonnet fuel filter was opaque making it really easy to see the colour of the fuel.

Most Manufacturer's state how much Bio percentage is acceptable in the owners manual. Most recommend no more than 5-8% (which is the maximum you'll find in pump fuel)

Have recently seen a brand new car (It hadn't even got through a full tank) that was run on 25% Bio, which wrecked the pump, the injectors, the DPF and obviously teh fuel filter..... Not covered under warranty because of the Bio, and the cost of repair would bring tears to your eyes

On a 70k Rangie, I'd steer well and truely clear

Yes, I don't have any experience of other diesels, but I understand it is common practice. Not so much to aid HMRC, but to check for air bubbles in the fuel line. This is an old picture (I no longer own the car), I circled the fuel line in yellow. You can see it just below the red dipstick handle.




I have also heard/read on internet that inspectors have been known to take samples from the underbonnet fuel pipe so even cars without a "see through" line could be caught out. Tank dipping is just the easiest and quickest method.

Bottom line, don't gamble more than you can afford to lose should they seize the car

Is the penalty permanent seizure of the car, for use of Red, or a fine?

I honestly don't know enough to comment further. I don't run red diesel (don't even own a diesel car) so haven't had incentive to investigate any of the stories I have heard, the general gist of those being, "They take your car if you don't pay the fine".
