Does Hydro-gen work for Diesel engines also?
A5: Absolutely. For larger Diesel engines you can put on two units. No need for a larger unit , this one does it all . We recommend buying one unit , then trying two, (we will discount the second unit )It is cheaper than a large one would be , if one happens to be down you always have one. If you then find the second unit to have not helped you we will take it back with a full refund. They will drastically smooth the engine out.
