I've been using OptiLube for over 6 years. It's an additive that increases lubricity. It's been reported many times that diesel fuel in the US, when spot checked, doesn't always meet the Government requirements for lubricity. I add 1/3 of an ounce to every gallon. I have bottles set up in a storage bay that hold enough to treat between 30 and 50 gallons, the amount I typically take when I refuel. I just bought their newest Cetane Boost product and will give it a try on our upcoming trip.
This discussion typically evolves into the guys who use additives and those that don't believe in them. Those that don't believe ALWAYS fall back on the old stand by.....If Cummins or Cat doesn't say to use them.....I don't. Well here you go: Cummins
I completely agree. But there is no way anyone can be sure they aren't sucking water from a fuel pump when getting gas. Even a little. Or condensation or fuel break down. Nothing the manufactures cando about it. It adds up over time. If you don't keep a full tank of fuel you could be getting condensation.
I'm more concerned about maintaining my fuel and keeping the bio bugs out of my tank. I agree with you a little lube won't hurt.
