What are the “variables” you keep talking about that affect the quality of the oil from vehicle type to vehicle type?

Grandma has a brand new Toyota Camry with very low mileage, travels several miles every other day, lives in Southern California and sometimes goes for a long drive along the freeway to see family. A teenager buys a used vehicle with 120K miles on the engine, lives in Phoenix Arizona and loves to tear it up with some stop start city driving in the dry hot summer heat.

This is where the Oilyzer product comes in, to measure the variables that determine safe and reliable oil changes. The main variables affecting oil quality over use are; • Condition of the vehicle engine. • Drivers driving habits. • Total engine mileage driven. • Environment the car is driven. Two additional variables, not as important as the others, is size of the engine (4, 6 or 8 cylinders, tim
