DIY or professional fitting?

Converting a diesel engine to run on vegetable oil by using a conversion kit is something the competent DIYer could attempt, but if you’re NOT very mechanically minded, I personally wouldn’t advise it.

I’m lucky, I live near Wolverhampton where DieselVeg are based and these guys are accredited expert installers of the German built ATG conversion system I had fitted. However when I was there I met other customers who had traveled considerable distances just to use this firm, many of whom were on their second or third conversion.

Whilst I have no attachments to DieselVeg I’m happy to give them my personal recommendation. If you're nearby, I’d strongly suggest you have these guys do your conversion for you.

You can buy converter kits if you're the competent sort. DieselVegsell them and there are other systems out there on the internet.

Personally I think cars are not only expensive things, but they’re deadly if they go wrong. Consequently I’d always recommend having a conversion system professionally installed.
