Adding oil to diesel?

[J9HHY]

I have heard that certain diesel cars can run with cooking oils poured straight into tank, or 50/50. I have also read that it can ruin pumps and seals. Does anyone know if a Peugeot 306hdi is ok? Also how much oil to diesel should I use? What kind of oil? And am I really gonna save any money? Will I lose a bit of performance? The price of fuel isn't getting any cheaper and I do roughly 500 miles a week! Was only planning on doing this in the summer too as heard it works better when warm!

Price up a diesel fuel pump for it and then work out the costs you're going to save.

Bio-diesel can be a little cheaper but can ruin some key components in a derv engine.

Alternitivly some cars will run on Bio/cooking oil ethanol mix for years and give very little bother.

Do a little googling on it!

take a look at your handbook, the one for my transit says not to use it.
