Photo 1/7 | Archoil AR9100 16 Ounce Poured Into Engine | After the truck’s dipstick read half a quart shy of being full, we topped off with our 16-ounce jug of Archoil. From there, the truck was started, idled for 30 minutes, and then taken on a 15-mile drive.

Knowing that changing to a thinner-weight oil wouldn’t alleviate the severe stiction problems with this truck, it would more or less be icing on the cake if the Archoil additive worked.

The additive can be had in everything from an 8-ounce jug to a 55- gallon drum. This 16-ounce container was used to top off the crankcase of a high-mile Super Duty test mule.

With the original injectors needing to be replaced at 150,000 miles, the owner fully expected he would once again be replacing them when he brought the truck to Flynn’s Shop in Alexander, Illinois.
Photo 5/7 | Archoil AR9100 Before Truck Stats | To see how poorly the truck could handle cold starts, it was parked outside overnight, in 20-degree weather. Because stiction issues typically subside as the engine oil begins to warm (due to the oil thinning out), we performed a cylinder balance test within 30 seconds of starting the truck. The result: just four of eight cylinders were in good working order. This meant half of the engine’s injectors were suffering from stiction (arrows).

Photo 7/7 | Archoil AR9100 After Truck Stats | The next morning, following a 15-degree night during which the truck once again sat outside, it fired right off and idled smoothly. As before, we ran a cylinder balance test just seconds after startup and were greeted with this screen: no misfires and every cylinder functioning perfectly. Seeing this F-350 go from a cold-blooded, rough-running basket case to a truck that ran as smooth as it did the day it left the dealership definitely made believers out of us. Archoil is the real deal.
