I did not realize any fuel consumption Difference after the first application. I used it for my F10 BMW and waiting to see if after the second oil change the consumption will be any better. The only difference i realized was in the first application of both products. So 1- changed the Oil added the lubricant/friction reducer + New 5-30w Synth. 2- gas additive then filled my tank with gas: Result 3 miles improvement /Gallon at the beginning then back to normal after the first tank... Maybe a bit smoother engine after the first oil additive too. I am sure it has some benefit to the friction reduction, but do not know if that has a lasting effect or not. Sure must add at every oil change.

I have been using Archoil AR9100 for the last 3 oil changes and the Archoil AR6200 every fill-up for over a year. This stuff is amazing. The AR9200 in the oil keeps my high pressure oil injectors clean and operating like they're new (200K miles) and it is hard to believe the tiny amount (1/2 ounce) of AR6200 in a 38 gallon tank of diesel would have any affect, but results don't lie. Cleaner burn, picked up 2 mpg and I dropped my tank last month to fix the sending unit and the inside looked as good as when the truck left the factory, maybe better.

The arch oil fuel modification is great! I used it on my 2016 Road Glide Ultra, which has a high performance engine and exhaust system, Thundermax ECM, custom wheels and klock werks wrapper front fender. Before Arch oil fuel modification, the starter would turn 2 to 3 times over and then start, slowly and then rev up. Now since I've been using the fuel modification for over 1,000 miles, when I start, she immediately starts... I get that POP, vroom... (I sound like a little kid).... But this really does work. You have to becareful how much you use, I just fill a little below the "1" and pour that into the tank before I fuel each time. Too much and you don't get the performance, but it wont hurt the engine. Litterally a little bit will do you....

This stuff smells though.... not like any fuel additive i've used before... what ever is in it, it works though. I'm sold on it and will use this all the time now. I ride 124 miles round trip everyday to work and back and this has proven to me the performance aspect. I haven't noticed improved gas mileage, but certainly throttle response, power and performance is much better.

I was very skeptical about this product but I decided to give it a try after watching videos of consumers raving about it. After I put the Archoil oil additive in with my oil change I realized that my block heater went out and I did not have the convenience of being able to plug in. I drove the truck as directed and did not drive it again for a week after adding the additive. when I went out to start my truck for the first time it was -0 and below (I live in AK), so I said, here we go this will be a good test. I let the glow plugs warm up and tried to start my 04 F350 diesel. I was shocked, it started up as if it had been plugged in all night. I could not be happier. I can not comment on the fuel additive yet because I have to warm the truck up so I will find out this spring if my fuel mileage has increased as well. Stay tuned.

I have used this stuff in two vehicles one being my 6.0 power stroke and the other a Nissan Pathfinder. I didn't even know about stiction I just thought diesels were real weak when they were cold but I put both the oil in the fuel additive fixed it right up. On my Nissan Pathfinder I had a check engine light come on it was telling me my catalytic converter was bad about $1000 to fix I change the air filter and added a bit extra of the fuel additive in about 100 miles the light went off and hasn't come back on since. I completely believe in this stuff!
