Bio,
Down here there are diesels running diesel/LPG and diesel/LNG systems 18 hrs per day 7 days a week. No problems. I know of a fleet of Mercedes buses on diesel/LNG, It has Mercedes blessing.
I have seen the insides of a Cat truck motor that Cat sponsored a trial of Bio. on a double B on long haulage. I saw the same thing as members on here show.
I am not in the biz of selling bio or WVO conversions nor do I work for the alternate.
If the engine manufacturers cant get it to work properly I think its best left.

I dont know the history of your wagon so I cant comment.
As I continue to ask, where are the cars that have run on WVO or Bio for 200k miles. These 2 fuels have been tried for over 20 years now. If they were that good, the car/engine manufacturers would be giving their blessing.
