4 air filters @ $12.50   = $50.00
13 qts. ATF  @$4.95    = $64.35 
8 qts. 80W90 @$2.95   = $23.60
40 qts. 5w30 @$1.25    = $50.00
Total                               $237.95 		 Amsoil Synthetic: 25,000 miles
2 oil filters @ $10.30    = $20.60 
1 TS29 Air filter           = $40.25
13 qts. ATF @ $7.55    = $98.15

Cost Comparison 2nd Oil Change.
 
Petrol at 48,000  = $237.95  Amsoil at 50,000  = $49.10
 

The difference in cost is $123.15 for the first oil change.

 

The test shows the Amsoil allowed the Dodge to travel 64 miles further on 8.90 gallons less fuel consumed. 8.90 gallons @ $1.45 = $12.91 saved per 1000 miles driven or $129.10 per 10,000 miles. The Amsoil air filter is a reusable filter that can be a lifetime filter. The Amsoil motor oils have a recommended change cycle of 25,000 miles. The Amsoil ATF has a change cycle of 5 times longer service life, which is in excess of 187,000 miles for this vehicle. The Amsoil costs less when figured on a cost per mile than the petrol products because 8 times as much petrol oil is used to go 25,000 miles. The difference is Amsoil cost $123.15 more to install and drive for 25,000 miles and will save $129.10 in fuel costs in the first 10,000 miles driven or $322.75 per 25,000 miles. The 2nd oil change involving Amsoil will cost only $49.10 while petrol will cost another $237.95 for 48,000 miles driven.
