Do fuel additives really work?

Nice... that's why I want a hard lockable cover as well... get the stuff out of the cab. Plus to be able to carry the stuff that I dont now because i don't want to fill up the back seat floor.

I feel I need to add this to my discussion here....

Fuel additives are like the Oil discussion... opinions are many and varied.

Yes, I use additives 100% of the time and yes, it warms the cockles of my heart..

BUT... that doesn't mean they are necessary for anyone else or that I am pushing them on anyone.

Yes, I believe they work, especially for me who lives in a northern part of the country where it gets cold and where condensation CAN be issue when the warm fuel in the tank cools off in the cold winter months.

Another thing to think about, if you take care of moisture in fuel or water, microbes cannot grow in the fuel because they need water to grow and start to flourish in the fuel, and the presence of water promotes microbe growth.

@Painted Horse brought up many good points , in the recent thread by a new user on his concern for his 22 6.7 Powerstroke 's CP4. He has a sound philosophy on fuel and does what he is comfortable with.

It's all about staying on top of the fuel and filter maintenance, knowing what you're buying, and what is your comfort level to design what your plan will be with fuel purchased and potential fuel additive use.

Another thing I have read about fuel additives is that for petroleum based additives, they cannot be a fuel system cleaner and lubricity adder at the same time IIRC...

K100 has organic chemistry and contains organic compounds. I'm no chemist but in simple terms, that's what makes it combine with water at the molecular level and allows it to pass through the CP4, to the injectors and into the combustion chamber with zero harmful effects.

But petroleum, or essentially oil, does not play nice with water and does not mix with water, hence demulsification...

So once again, do your own due diligence and research. Use what you feel comfortable with using... all i do is pass on info in a take it or leave it attitude... no harm no foul.

But truthfully, if anyone still thinks an alcohol based additive llke K100 will blow up a CP4, I say unabashedly, that is not true. It has well over 100k miles using K100 in every tank, what's nice about it is you cannot overdose it, and I still have my original CP4 which if the compound containing an alcohol in K100 was harmful, my CP4 would have blown up already.

YMMV...

I'm not very religious about using additives in my fuel. Yes I do at times add some, But just as many tanks of fuel go with out.
I use an additive to hopefully fix or avoid problems. ie I more apt to use an additive to prevent gelling during cold weather than I am to use it in summer months.
Summer time, I'm usually looking for an additive to increase Cetane and Lubrication. I'm just not sure either of those are measurable. I just hope that adding lubrication improve the chances of my CP4 lasting longer but will it last 150,000 or 200,000. There is no way to measure that.

I don't see an improvement in fuel milage that I can measure. So did the Cetane improvement really help? And my driving varies so much. I can haul a load of horses up over a mountain pass and get 10.5 mpg yesterday, and pull a dump trailer to the gravel pit and get 14 mpg today. Tomorrow and I can drive 100 miles empty and see 22 mpg. so my average for a tank of fuel could be 10.5 or 22 or some average of the combination. I just don't believe I can be accurate with a 50 mile average.

I started using Opti-Lube XPD back in 2008 when Ultra Low Sulfur diesel first came out. In an effort to save some money, I shifted over to Opti-Lube Summer ( which adds lubrication and Cetane at lower cost) I bought gallon jugs of Summer and XPD and they have lasted me a couple years. So I can't speak for other brands.

I do buy my fuel from stations that move a lot of diesel. So I'm not worried about the freshness of the fuel. Utah has a low humidity, So I don't even worry much about condensation in the tank. I've never seen any moisture in the fuel/separator when drain it. I typically drive my trucks about 33,000 miles a year and trade them off every 3 years at 100,000. So I can't give much info on how they held up 200,000 or 300,000 miles.

Thankfully mine spilled, or dripped, or leaked, whatever, inside the cargo rack under the rear seat which is all plastic and it all wiped right off. The smell is pretty much gone now too. My bed is wide open, no cover, or box or anything to put things like this in, and I would need a step stool to reach into a box if I had one.

I have that itch one gets when they are looking to upgrade. While my 2019 Platinum F-450 runs great, it is 5 years old now, 6 according to the build date of 10/18, 3 years left to pay it off, making it 9 years when paid for, it was 4 when I bought it. When I retire in 5 years, do I want an 11 year old truck? So If I were to decide to upgrade to a 2024 truck, I think I will look into one of those side boxes that swing out for storing this stuff.

I don’t think you have it in the US but in Europe you can readily get premium diesel. It’s higher cetane and has all sorts of additives. I pick it up in Luxembourg when I drive through as it’s the same price as normal diesel in Germany.

Kwik Trip carries a premium Diesel, sounds the same as you describe. NOT the same price though, about .50 a gallon higher.

I remember reading something on Euro diesel, that it provides more lubricity (460 vs our 520 IIRC). Can't remember anything else than that... so whats the difference between non-premium and premium cetane?

Just looked into it... 2 to 5 cetane points higher and stuff like a fuel system cleaner, etc...

For Total Stations the premium is around 54 and the normal B7 is a minimum of 51 cetane. The price difference is 10-15c per liter so that is similar to your premium as well.

If you're talking about these, then you might want to reconsider. I bought a set of these (different brand, but identical in every way), and they lasted about two months. Too much vibration, and where the rods across the backside that secure them to the side of the bed broke completely. Plus, they don't support a lot of weight, so you won't be storing much of anything in them (like tools). Utterly useless and a waste of money on my part, as they weren't repairable.

Those storage boxes look Good but are useless for any sort of weight. Good heads-up for anyone looking at them.

Maybe they were made for that hard-core metro man that just has to have their crochet needles and yarn *****.

Yeah that's sweet... getting fuel with that high cetane. Ours here in New York state has to be a minimum of 40 and K100D only adds 1.5 to 2 points, and it's B5 max more than likely... if it's a B5, it doesn't have to be listed on the pump I read. Anything over B5, it has to marked on the pump.

Last time I talked to the fuel manager where I buy it, they get from two different fuel distributors... the fuel is nice and clean. The lower filter always comes out clean looking but I use the K100 every tank which dissolves alphaltenes back into the fuel and it has a fuel cleaner it as well.

BuiltRite makes those molle style metal plates that mount to the truck. You can get ammo cans, smaller to larger to mount to those plates, including the large ones that hold mortar shells in them, online. Lock kits for ammo cans can be found as well, and those metal ammo cans have rubber seals on top for a waterproof container... that's my plan at one point...

it certainly keeps the motor quiet. The dogs hear the Peugeot before it’s even in the yard but they mostly don’t hear the pickup.

I found this article very enlightening, regarding cetane. The other articles linked at the end are also informative:
