In my experiences, CNG would be the preferred primary fuel, although more costly and rare. Many more things are possible since it tends to not knock, tolerates lean burn, and not pollute the engne oil. We were getting 300K miles on our vans 20K between oil changes before the mechanics got paranoid about the main bearings which turned out to no be wearing much at all, so perhaps 500k between overhaul.

The downside was only about 125 miles range with two 25 gallon tanks at 3K psi, less in winter when they added air to keep pressure up. I had to refuel 3 times a day in winter
