I will see if I can find the good ones again, they did wear scar tests for different additives and cetane tests, the one I got was the second best for the lubracation, the best one isn't available in Canada that I have found. you have the same cp4 as I do, I think it was 2020 when the first updated one came out and then in 2024 for the 3rd advancment. I would for sure do the desaster prevention kit, make sure you buy a second generation kit not the original. I am even thinking of putting one on mine, but not because I expect it to blow, but maybe more of a just incase 🤣 I do also plan on visiting the USA again when the prresent situation is over and that would mean using USA diesel so might as well be safe.
here is a good video
