Consumer Description

My truck passed the recall PICO test right at 20,000 miles. The dealer put thicker 0w40 oil in. Less than 2,000 miles later, upon hard acceleration from 5-8mph, the engine climbed to 58mph then lost power, shifted itself into Neutral and coasted to the side of road. Truck was towed and told the engine seized up. Changing the oil did not make sense to me as lubrication was always available previously, thickening it does not change the port mill sizes for properly oiling the crank bearings. Now the new engine is revised but I see failures in low milage 2026 models happening.
