In 900,000 miles it took Amsoil 36 oil changes. GM OLM = 144 changes. Well if the math is right thats 108 more oil changes considering if he had time and time cost when your short on it when your driving 112,500 miles per year. Add another cheap $10 for labor on the oil changes = $1080.
It's easy to look at with simple math...I would think he had better things to do than with the extra 108 oil changes.
