Review on 🚚 Mobil Delvac Synthetic Transmission Fluid 50, 1 Gallon by Charles Chambers

I have driven my G56 Mobil delvac 50 10,000 miles, they switched to Amsoil MTF 5w-30. Mobil is a pretty good transmission oil, but it makes the transmission shift slowly and clumsily. And when the temperature is below zero, the truck is almost uncontrollable, some gears are blocked, others are grinding. After switching to Amsoil, even in cold weather, the gearbox shifts smoothly like a normal car. It's very close to Mobil when it comes to stopping gearbox rumble. I'm not an Amoil fan. This is just my personal experience with my Ram truck. I'm keeping my five star rating because I think Mobil is a good oil, just for a tractor trailer, not a G56.
