I have used the Hyper Diesel Additive, and have found that after approximately 200 Kms that I Believe, (only two tests to date) it increases my mileage as I run approximately 8.8 litres per 100 km with the additive in the tank. Our F150 Diesel is primarily used for highway driving 95% of the time and the mileage for the truck is amazing based on its capabilities.

Rislone Hy-per Diesel Fuel System Treatment (4740)

Seems to cover all of the same bases Stanadyne Performance Formula (what I use) does plus being an injector cleaner:
  • Complete Fuel System Cleaner
  • Cetane Booster & Diesel Treatment
  • ULSD Sulfur Substitute Lubricity Additive
  • Contaminant Remover
  • Corrosion Fighter
  • Fuel-gelling Preventer
  • The Best Diesel Additive Money Can Buy
After poking around, here's my Executive Summary:
  • Available on:
    • Amazon: $16.00/bottle (only one vendor w/only 1 bottle left in stock?)
    • O'Reilly Auto Parts: $11.99/bottle
  • Single bottle treats 30-35 gallons of fuel
  • Dual chamber bottle to keep additives vs injector cleaner separated until used
  • Comes w/spout to add to capless fuel tank systems
  • They recommend one (1) bottle every 5000 miles = not an every fill-up treatment
    • Unsure how this is supposed to help w/overall MPGs if only used every 5K miles?
    • Might help w/MPGs for the one (1) tank you treated, but after that?
  • Not many reviews on either O'Reilly's or Amazon's websites
    • YouTube videos are 5+ years old, so not sure why not many reviews
    • Quirky blonde in YouTube sales video is a trip....
IMHO: Might try on next oil change but I wouldn't be using this on every fill-up due to injector cleaner

Well done on the executive summary!! Yes you are 100% correct in regards to the mileage summary as this lasts just slightly into the next take of gas. I generally use the higher grade of Shell Diesel which costs more per litre and I am not sure what the Benefits are here and need to complete a little bit more research.

I use this as well every 5,000 Kms

IMHO the cetane rating of diesel should be displayed at the pump. 40 minimum is not high enough for modern high performance diesels. I've always used additives for my Ram Ecodiesel. Strange that Ram suggests "Power Service Diesel Kleen" for the Cummins, but nothing for the Ecodiesel. Raising cetane and lubricity can't be bad. Been using Hot Shot' EDT mostly, though.

Interesting thanks for the comments!

Right, which is why I was questioning what the objective of the OP here is. If you are looking for better MPGs on every tankful, then you need to use a fuel additive with a Cetane Booster on every tankful; like the Motorcraft Cetane Booster or combo additives like Stanadyne Performance Formula or Hot Shot's EDT.

I guess using Rislone Hy-per Diesel Additive once every oil change/5K interval is better than doing nothing at all, but as I already mentioned I wouldn't be using this every tankful because of the injector cleaner component, and if you only run every 5K, then you only get the MPG improvement from the Cetane Booster every 5K... I run Stanadayne Performance Formula every tankful, not because of just the Cetane Booster, but rather everything else that the Performance Formula provides -- the Cetane Booster is an extra bonus. For a discussion on what Stanadyne Performance Formula offers, please see this Diesel Fuel additive recommendations thread

If OP is only concerned with improving MPGs. then I'd look at the Motorcraft Cetane Booster or something like Optilube XPD, which I think is the one "claims" to help with average miles between regens @Smokewagun = I have never used the Optilube XPD, so I cannot substantiate their claims!

What I'm saying, if you go to the gas pump, you have a choice, typically 87 octane, 89 octane or 91 octane or even 93-94 octane. With diesel it's a crap shoot. We get screwed. If I bought a bottle of Scotch, like to know that is 12 year old 80 proof, etc, not just that it's a bottle of booze. I should also mention that a small percentage of the early Ecodiesels spun rod bearings. Best reasoning that I've read= low cetane fuel caused detonation and excessive loads on the rod bearings. These European high performance diesels were never designed to run on crap fuel. Using a cetane booster is cheap insurance.

Agree with your comments Cetane Booster makes sense, however remember that most high pressure fuel pumps are fuel lubricated and require the lubrication qualities of first cut diesel. Example if you run Jet Fuel in a Diesel engine which is second cut through the refining process if you do not add a little bit of turbine oil you will wipe out the high pressure fuel pump due to low lubrication. Therefore the balance of Cetane Booster needs to be correct bit of a balancing act as cold weather will also affect this balance.

I haven't seen this one on the shelves here. I use DieselKleen + cetane boost every other fill up. It's always on the shelf at Canadian tire and usually on sale.

Agree that cetane rating should be posted. I stick with the big name stations (Petro Can or Shell) that move a lot of diesel. You can definitely tell a difference if you get old or subpar diesel.

I buy the Hyper-Diesel at Canadian Tire
