So looking to see what oils you guys are using for your 6.7s?

I’ve been running Rotella T4 since I’ve had the truck and not one oil leak, and I’m thinking of switching to a synthetic oil or using the same oil with added Hot Shots FR3.

I’m leery of changing oil‘s because I swear every other vehicle I’ve had when I went to synthetics I started getting oil leaks around the motor maybe that’s just me and my luck.

I’m sure Amsoil is going to be brought up but that’s really pricey oil and have not seen proof it’s better than any other.

My truck has been recently (dirty word) so it can breath and not eating it’s own soot in its oil so interested in seeing what most are using and why.

Hot Shots FR3 supposedly increased 14 horsepower in a real world Dyno for Firepunk so that’s interesting.
