Fleet Taxi Test Part 2

NOTE: For clarification regarding the APPARENT DISCREPANCY AS TO WHETHER VEHICLE 3 ACTUALLY RECEIVED AUTO-RX®, please CLICK HERE.

The taxi fleet test data has been extended out over a few more OCIs. Also, another test cab#8 was changed over from a lucas oil additive to Auto-Rx® at the 15,000 mile mark. The results speak for themselves.

Results focused on gas mileage. Empty cells indicate mileage not achieved yet or not reported. Mileage is averaged over as close to 50 gallons starting on the first fill-up after the PM.

2 vehicles were added, 7 and 8. Both vehicles received a Lucas oil additive at every oil change on the same PM schedule; that is 3k intervals.

Please note that at 15K miles on Vehicle 8, Auto-Rx® was used, and Lucas was discontinued.
Notice the improvement.

Again, a ScanGauge was used in each vehicle. The readings were all off to some degree but consistent, that is repeatable, and show trends, which is what we are looking for.

The maintenance dose was 4 ounces because these vehicles are in severe service and were a bit sludged up at the start of the testing. Otherwise, 3 ounces would have been used.

Vehicles 1 and 2 showed the only significant increase in gas mileage. Compression figures are coming. I just have not collected them all from the four mechanics that worked on these vehicles.

A reminder about the vehicles

2 Same as 1
3 No Auto-Rx®
4 No Auto-Rx®, flush used
5 No Auto-Rx®®, flush used
6 No Auto-Rx, fake gas additive
7. No Auto-Rx®, Lucas every 3K
8 No Auto-Rx®, Lucas every 3K, Lucas stopped after 12K and Auto-Rx® started at 13K
