I have a biodiesel processor I was given, a good one, brand new.

I'm not aware of any off the shelf processer that is any good.

You mention drywashing and titrations.

Most people skip titrations now and run a two stage, compensating for first stage conversion in the second stage chemicals.

I, personally, would not drywash for a td5. Ensure 100% conversion (overdose stage 2 if need be - your soap production on S2 will be minimal anyway) and then water wash and dry properly and you will be fine.

Id, basically, run properly made bio in more or less anything. It's the dpf regen cycles that are the issue.

2004 Discovery TD5. I have a biodiesel processor I was given, a good one, brand new. I have a source for used veg oil (restaurants/chippies). IF I were to do it, it would extremely good grade stuff. Not "hooch". titration test, ph test, dry washed, etc etc.

The thing is, the guy I knew years ago who did it by the thousands of litres - He gave up because he spent the 6 grand he saved on fuel, getting his engine rebuilt. He was convinced it was due to 'polymerisation' of the oil which wore away piston seals, something like that anyway. He knows his stuff but said he can't be 100% certain the biodiesel caused it, but seems pretty sure it did, and he was making top grade stuff (he runs a fuels company).

I don't want to bugger my Disco, took me a long time to find a good one and planning on keeping 'forever'. Also, my friend told me when you buy methanol you get flagged can get randomly inspected by the stasi c*nts at HMRC. Me and they do not mix so that may be reason enough to not go ahead with biodiesel plans, but if it can run well in the Disco and won't do any harm, I may look into it further.

Thanks

You have top grade kit to make yer own fuel. Yer mate did the same and knows what he's doing due to the nature of his job. He's convinced it's the cause of his engine requiring a rebuild after failure. Yer wondering if the risk is worth it.

Have I understood this correctly?
