Below is the OCA using Amsoil SS 0w20 for about 6k miles in extreme terrain towing a 5000 pound trailer in mountains, desert and extreme cold/heat. I’m most curious on why the viscosity is off. The higher silicon can be attributed to changing the oil pan and the silicone that was used to make the gasket between the upper and lower oil pan so I expected that. I’m thinking of switching to Pennzoil Ultra Platinum 0w20 just because I thought amsoil would have performed better.
