Thread: 300tdi on bio?

No conversion is needed on a 300tdi, just fill up with 100% diodiesel. There is a changover period as it flushed crap out of the fuel system so you will more than likely need to change the fuel filters in the first 1000 k's or so and keep checking them. The 300 tdi seems to run a lot better on biodiesel, makes it noticably quieter.

I bought my biodiesel from SAFF which run a few servo's in melbourne that sell it at the pump.

i heard somewhere dunno how true that it can eat away at gaskets and seals and stuff, but if it doesn't need no mods than thats the go.

There is a possibility that if your fuel injection pump is getting long in the tooth that running biodiesel will speed that along. Rebuilding a fuel injection pump is quite expensive.

Bio good stuff, when i had my 300 tdi we run it on nothing else, no problems.

just remember that bio is more of a solvent than dino diesel, so all the crap that has built up over the years in your tank and lines will break down and end up in your filters, possibly even blocking them. Its no big deal you end up with a cleaner system anyway.

As for Gaskets, old days with rubber gaskets, they tended to dissolve or swell, the modern stuff no problems

Just don’t fill up at Saff until after 830 am, you don’t want to joint the long Que of trucks filling up before they head interstate.

Bolloxxx, the 300tdi is lubed by the motor oil, bio no efect

Looks like you've been reading excerpts from my version of "this is your life"

Umm no. It isn't a inline pump lubed by the engine oil. Its a radial pump lubricated by the diesel fuel.

Only going on personal experience and hearsay. Several on AULRO, me included have found the need for a pump replace/rebuild shortly after taking up biodiesel.

As in my first post, not saying it is a certainty, but it is worth considering.
