Archoil Starter Kit - 16oz AR9100 Friction Modifier + 8.45oz AR6200 Fuel Treatment

This product does exactly what it says it does. On my 6.0 powerstroke Ford (05 F350) -- The friction modifier did the trick, it is hard to tell if I got a fuel mileage increase, but it would make sense if I can tell the friction has been reduced by the engine quieting down etc. I am sure that equals at least some gain in fuel mileage. I also seem to feel a little more power. I analyze my oil at each change, it will be interesting to compare this analysis with the older ones where I haven't used Archoil. As for the fuel treatment, same thing, I have run it with it, and I've run it without, there seems to be a little uptick in fuel mileage, again, it is hard to tell, but sure seems to help. All in all, I am firmly confident the product is paying for itself, no doubt in my mind! On my 2013 Ford Fusion Hybrid -- WOW. This car already gets good mileage, so when mileage does increase, even by 2%, you can tell. The Atkison cycle 2.0 that is in these Fords is a good little engine, but due to the type of cycle, it tends to have a little bit of a vibration, or almost a shutter sometimes when it starts. When I added the friction modifier to it, I definetly noticed a gain in smoothness. As for fuel mileage, I put 50-60K highway miles on this thing per year, so I have a good grasp on my mileage, I get right at almost exactly 38.5 MPG when I am highway cruising without Archoil, when I implement both the friction modifier and the fuel treatment, I get just a tick over 40 MPG. That is 4%. - During the winter months, the engine runs more frequently, so I expect the spread to increase even more, I would guess in the next month I will be seeing a 5% or more increase in fuel mileage above what I get without Archoil products. Am I saving money with Archoil in my hybrid? As far as fuel savings goes, it's close to a wash, as winter goes on hopefully I can see a clear cost savings. What I do know is my engine is running smoother, and again that's telling me less friction, so since I am breaking even on fuel, and then I am picking up the added benefit of less wear in my engine, I have to conclude that I am coming out ahead using Archoil in this vehicle as well. Count me in as a fan!

Ok we see oodles of products that tell you that you will get better gas mileage and 99% of the time it’s just not true. I googled Consumer Reports what the best friction modifier is when I heard about this product. To my surprise I thought Mototkote was the best until I read CR study. I have a 99 Ford F-250 V-10 gas truck approaching 300,000. It’s a 35 gallon tank gas hog! I change the plugs/coils between 65-80 thousand miles so I have consistently got 350-375 miles per tank. So I ordered the kit, modifier-fuel treatment. Change the plugs as it was due then the oil and added the treatments. My fuel gauge float has gone bad and jumps around so I trip the mileage odemeter at every fill up. At first fill up once I reached 350 miles on the tank I filled up. To my surprise I still had 8 gallons left. This last fill up was at 414 miles and I still had 3 gallons left. I don’t work for this company nor am I one of those people that are paid to falsely right a bogus reviews. This stuff really works and I’m buying more to put in my commercial lawn equipment.

I put the AR9100 in my 2004 F250 6.0 Powerstroke when i changed the oil. Almost immediately I could tell a difference. Cold start up was way smoother, the engine seemed to run quieter, and my truck just ran better. I towed my 11,000 pound 5th wheel and got the best mileage I have ever gotten. This is the best additive I have ever used. I will definitely use again at every oil chage!

I really like the product. The fuel additive is awesome, even have it in the lawnmowers and the mowers run smoother. Great stuff.

a bit pricey but, definitely helped with cold weather starts in my F250 with 6.0 turbo duesel

Quality all around 6.0 motor loves this stuff and will show you return favor by investing in this stuff by not sticking and running long miles 👌

Arrived Earlier than Expected. 6.0 powerstroke essential. Helpful tip, if your in colder climates think about changing to a lower viscosity oil. Keep the block heater plugged in, and wait for the glowplug light to go out. This product won't magically repair a bad injectors. My personal opinion I only use this additive with a non synthetic oil ( Motorcraft 15-40), and oem Filters. Bottomline it works, but it's not a cure all.

Haven’t really noticed any change in performance or fuel mileage, others swear by this product, I’m just not seeing the bang for the buck.
