Been using the AR6200 on all my cars. I use it every fillup. I get better gas mileage and the engine revs smoother. My cars are direct injection engines and with almost 100k miles, no signs of slugishness and misfires.

Keeps gas good for years

Been using this stuff for about 6 years.I always keep some extra gas in the shed , about 30 gallons. Over the lock downs I just forgot about the extra gas. Last week I put 10 gallons of 3.5 year old gas in my truck, and it ran great, with zero issues. Did around 7ml per 5 gallon jug.

Another Expensive Product….

Using this Stuff in our 2018 EDGE V6, and 2022 EcoBoost 3.5 F-150. I “Think” It’s doing Something? Milage hasn’t moved like some reviewers have reported, But I think it’s Cleaning or Helping to Keep Clean The Valve Train and Injectors?? Again, I can’t SEE if it’s doing anything, so I’am in Great Hopes that it’s as good as Archoil makes Claims to Fame on. My last Bottle showed up All over the Box / Packaging, I sent a message to them and they Sent a New Bottle in Replacement. Shipment on the Replacement was kinda Slow but I did Appreciate them Replacing the Near Empty Bottle that USPS Actually Delivered the First Time. It musta Stunk up the Whole Mail Truck Full of Mail. Thanks to Archoil for the Great Customer Support!
