I found this browsing a freelander forum. I known the owners manual says no to Bio.. but don't worry the same site details the repairs of the high pressure pump

anyways...

If its good bio and contains very little/no meth once finished it should be just as good as normal diesel.

Seals harden over their life anyway, one of the reasons why the kits are made as they constant hot-cold cycles kill the rubber at some point and with the worse weather we have had over the last few years its no surprise that older cars tend to leak a little more once the weather cools down more over night

SVO itself isn't good for this but its a fact of life if you save with one thing something else will take it away...

I did run my old Discovery Tdi300 on cooking oil, but I don't think I would risk it in my FFRR lol No longer FF owner but still interested. Present car Jaguar XE
