I have a friend who wants to know if he can run his 2014 Dacia 1.6 (Renault 1.5 dCi engine) on 100% biodiesel.
Has anybody on here had any experience with one?

All 2014 cars will have a dpf which means generally bio is a no no. A few can get away with a blend but it can be risky.

Why is a DPF problematic with bio? Are some of the trapped combustion products difficult to burn out of the DPF - or is it the regen cycle itself the problem?

It is the regen Tony. As it happens on the exhaust stroke there is no compression and therefore the rings are not under tension. They can/will let bio past into the engine oil. If an increase in oil level isn't spotted and dealt with there is a chance of polymerisation between the engine oil and bio which can lead to a siezed engine.

Or before polymerisation happens, the rising oil level can lead to ... let's call it deja vu, Tony!

I'd knock the DPF out and get a remap... about £100 around here to have it mapped out

that's only a tank and a half of fuel

and bio without a dpf is better for the environment than diesel with one
