Mineral Vs Synthetic (Some comparisons)
For purposes of comparison, we have taken a well-known synthetic engine oil, Amsoil 10W-40 synthetic, and contrasted its characteristics with those of several prominent 10W-40 conventional motor oils. Below is a condensed summary of the results of several closely-monitored field and laboratory tests:
| Test | Amsoil Synthetic 10W40 10W40 | Petroleum based oil | |
| Effective lubrication range | -60 to +400 F | 0 to +300F | |
| Visc. incr. after 64 hr. test | 9% | 102 to 400% | |
| Wear (mg. wt. loss, Falex test) | 1.1mg | 3 to 6 mg | |
| Fluidity @ -40F | flows freely | solid | |
| Volatility (evap. @ 300F for 22 hrs) | 1% | 28% | |
| Crankcase Temp.(Track Test | 240F | 290F | |
| Flash Point (D92 test) | 470F | 400F | |
| Oil consumption (50k miles) | 42% less than petroleum oils | ~ | |
| Intake valve deposits (50k miles) | 32.1 grams | 75.5 grams |
