L	3 years = A * [3 * (H - J) - I]	$5,476.40	$/year
M	4 years = A * [4 * (H - J) - I]	$7,785.20	dollars
N	5 years = A * [5 * (H - J) - I]	$10,094.00	$/year

* Many customers tell us they save maintenance expenses as well as fuel by extending oil changes and the lifespan of components such as air compressors, alternators, belts, hoses, etc. by reducing idling.
