Even a brand new vehicle's performance will decline if not regularly treated with a fuel system and engine cleaner.
AR6400-G uses PEA detergents to quickly and safely remove gum, varnish and carbon from the fuel system and engine. AR6400-G will also clean carbon deposits from intake valves on manifold injected vehicles, and help to remove deposits from turbochargers and EGR valves.
AR6400-G's detergents remove carbon build-up from injectors (pictured). Dirty injectors cause rough idling, misfires, poor fuel economy and black smoke due to incomplete combustion.
Modern GDI vehicles are especially vulnerable to carbon build-up issues as fuel is delivered directly into the combustion chamber. Use of AR6400-G removes heavy deposits and restores power and performance.
Most auto manufacturers recommend regular use of an injector cleaner for GDI systems.
Manufacturers including BMW, GM, Honda, Toyota, Volkswagen, Mercedes-Benz and Audi recognize that the levels of detergents required by the EPA to be present in gasoline is not high enough to maintain optimal engine performance.
AR6400-G will remove deposits which have built up over time to restore lost power and fuel economy and maintain the fuel system.
AR6400-G is a highly concentrated fuel system cleaner designed to remove existing deposits from your fuel system and engine. AR6200 Fuel Treatment is added to every tank of fuel to boost performance, ensure fuel quality and protect the fuel system from wear, deposit formation and corrosion. We recommend using AR6200 at every fill-up between AR6400-G treatments.
Removing deposits which have built up over time will restore power and fuel economy which has been degraded by deposit formation. Using a fuel system cleaner regularly will maintain optimum fuel economy and power. AR6200 Fuel Treatment is a maintenance product and will help keep your fuel system clean in between treatments, but in order to remove heavy deposits the higher concentration of detergent offered by AR6400-G Gasoline Fuel System Cleaner is necessary.
Yes, you can use AR6200 at the same time as AR6400-G.
In my kia niro it didn't help at all. But my car is new.
But in my scooter (motorbike) it helped to remove jerking.
Archoil products are great. Mileage went up on the honda accord. Went from 520 per tank to 570. Car runs smoother too.
I have used arch oil for years now and this product still surprises me. It works so well. Now obviously any reading this is probably wondering if this project is worth the extra investment. My answer is a resounding yes. If you are researching you see the claims of how this product helps with combustion which results in a clean engine. With my Toyota hybrid that I’ve owned since new started getting sluggish in throttle response and fuel economy was going down. My truck I bought with 50k miles. Since I put the first dose in the fuel economy has gone up. My hybrid from average of 46-48mpg to 52-56mpg. Truck not nearly as impressive but still a help at the pump 11-12mpg average to 13-15 average. Obviously we can’t see what is going on inside the engine but from the fuel gains something positive definitely happened within the combustion chamber. Highly recommend using all the products ar6400G, ar6200, ar9100. I’ve seen the results, and they work.
After two bottles of AR6400-G Gasoline Fuel System Cleaner on my Toyota Tacoma with 237k mile the truck idles more smoothly and there's no more black smoke at startup.
