I will provide evidence and conclusive test results with other leading brands of synthetic and conventional oils where Amsoil beats the rest. So, seven tests were run on the engine lubricants during the motor oil testing.
Fuel accounts for roughly 37 percent of Class 8 truck operating expenses, and reducing fuel expenses is a top priority for truck operators.
I will show in the charts to follow, AMSOIL outperformed Mobil 1 in all five areas with 5w-30 motor oil. Please read more.
After 409,000 miles without an oil change, the AMSOIL-protected Mack E7-400 engine in this truck was as wear-free as an engine in comparable service treated to TWENTY TIMES the oil changes.
