If you like to change your fluid early and often, I would vote redline. Why, because FCP Euro sells it and they have lifetime warranty on parts and fluids, including engine oil. (Only other brands they really offer are liqui-moly, motul, pentosin). This can be useful especially if you plan on owning long term. If you’re going to sell truck in a few years disregard and use whatever your heart desires. I’m thinking of this route as my truck is about to turn 4 yrs old and I’m in the same boat where I may change all fluids even though I’m only at 14k miles right now. Sent from my iPhone using Tapatalk
