Looks like Shell has a new addition to their Rotella line up called Gas Truck. It's intended for use as it's name says in gas engines. It's available in 0w-20, 5w-20 and 5w-30. I know a lot of us have been running Rotella T6 in our rigs and I thought I'd pass this along this new oil we can add to the endless discussions of which is best. Looks like it was just released last month.
