Putting together a Dan Watson article comparing petroleum oil vs synthetic oil, I came across this summary comparison that looks at the cost savings of synthetic oil vs petroleum oil in terms of direct savings as well as the indirect savings realized by increased fuel economy.

Cutting to the chase, you can save over $500 a year ($100 less if you spend time to change your own oil) using Amsoil Synthetic Oil vs Petroleum Oil in your diesel truck. The following figures are based on a Duramax diesel truck driving 24,000 miles annually.

Petroleum Oil (4,000-Mile Changes)

Ten quarts @ $3.75 each $37.50 | 6X = $225

Pleated paper oil filter $15.00 | 6X = $90

Total for materials: $52.50 | 6X = $315

Total for Labor: $20.00 | 6X = $120

Petroleum annual total for oil changes (material + labor): $435

Synthetic Oil (Extended Drain: 24,000-Mile Changes)

Twelve* quarts @ $8.75 each $105.00

EaO-52 filter $19.00

Total for materials: $124

Total for Labor: $20

Synthetic annual total for oil change: $144

*Two quarts added for make-up oil

Fuel Economy Comparison (24,000 miles)

Petroleum Oil

1,600 Gallons @ $3.00 per Gallon = $4,800 in annual fuel charges
Based on Fuel Economy of 15 MPG

Synthetic Oil

1,520 Gallons @ $3.00 per Gallon = $4,560 in annual fuel charges
Based on Fuel Economy of 15.79 MPG (five percent average improvement)
