Recently purchased a 2023 32' motor home with a 7.3 Godzilla motor. I've weighed the coach several times, it's about 23,300 lbs fully loaded to travel with both of us in our seats. add the GMC Canyon and we're moving about 28,300 lbs. With that said we're in the pacific NW with many long steep hills, and plenty of mnt passes to travel up and down. I'm saying all this to emphasize that the engine works very hard but I don 't abuse it. I am trying to decide what to use for a motor oil. The manual calls for Motorcraft 5w30 syn blend which I'm fine with, I used it for 150,000 miles in my Ford Escape. My plan is to run the Motorcraft and boost it with Schaeffer's 132 Moly EP and probably stick to 5k runs. Looking for some input and open to suggestions. Thanks
