biodiesel and winter (1.9td)

[Harlequin]

sorry bit of a `newbie` - but do I want to add anything to the bio diesel im now running over the winter? its B100 waste veg oil based

If it's a Bosch XUD then unlikely! I'm running 75% WVO 25% misfuel and it's been running great down to -6 so far. If you were worried 5% petrol wouldn't do any harm. Put some of your BD in a jam jar and leave it outside to see what happens to it.

so adding petrol can help? or `regular` diesel?

am a little confused!

You can add diesel if you like, but you'd need a lot more of it to have the same effect as a small amount of petrol. 5% petrol would have a signficant thinning effect, but like I say most likely you don't have to bother. Have you had any starting issues? What sort of temperatures are you seeing where you are? If it's commercial BD, the manufacturer might already have winterised it.

currently `only` minus 5 outside and im way down south in Eastbourne

and no , no starting issues , well it didn't catch earlier , but a second heating of the plugs and it was fine

As the previous poster mentioned, the problem with low temps and bio fuels is viscosity. Your aim is to make sure it flows well(ish) even at start-up. Diesel helps but petrol helps a lot more as it's an extremely good solvent. Try it and see. You'll save money as well.

running well now its above freezing - heard a vocal discussion when I went to get more earlier , apparently the provider doesn't `winter` the WVO as much as he should ........ but at £1 a litre its doing well
