I notice on the Spritmonitor page one of the fuel alternatives is for vegetable oil. For years I have been adding 10% to my Peugeot Partner after each fuelling.

Has anyone any experience of using this in a TDi Yeti?

Does it not say on the fuel cap "no bio fuel"?

It certainly says as much in the owner's manual, in its charmingly mangled way:

Your vehicle is not adapted for use of biofuel (RME), therefore this fuel must not be

refuelled and driven. The use of biofuel (RME) can lead to damage to the engine or the

fuel system.

I believe veg oil will murder your Yeti! I think it is to do with the immense pressure in the fuel injection system and the veg oil being too viscous to run through it.

I may well be wrong though

I think the problem is with modern high pressure injection pumps which rely on the fuel for lubrication and the risk of smelling like a chip van.

Chip oil is great for making smelly old Mercedes without the turbos aka 5th gear, but I personally wouldn't put anything like that near my Yeti.

I think that using veg oil as fuel will batter your engine although you may be abe to get it chipped

You're the 'salt' of the earth Killy

That just fuels the argument.

I was just wondering if say, 10 - 20%, would affect the system.

There are a number of Dutch and German web sites that say it would be no problem. Others reckon it's a disaster waiting to happen although most of those say the biggest problem is that it will rot the fuel hoses.

Although I will continue to add it in the Peugeot (non turbo) I'll give it a miss in Skoddy.

BTW the language in Dutch version of the handbooks is equally convoluted. Lots of double negatives etc.

Numerous issues here:

Veg oil does not have the lubricity of diesel oil, hence the problem with fuel pumps and injectors.

Used veg oil is full of acids and countless other unmentionables, all designed to eat away your engine from the inside.

Pure veg oil contains chemicals that will gellify the engine oil. I have seen engines seize because if this. Even with highly refined biodiesel, at anything over a few %, those OEMs that don't forbid it insist on seriously reduced oil change intervals.

It is total false economy. Use it in a 90s diesel if you must, but a modern common rail unit....? Your call...
