Was reading some more last night on Class 8 FE. Came across these:
DEFLECKTOR WHEEL COVERS
The Fleet Air Filter
Microblue Racing Products
And, a retailer of such devices
Truckrfuelmileage
The Microblue site has some interesting stuff on micro-polishing bearings, axle and trans gears, etc. A fairly high claim on friction-reduction. An interesting thread on
The Truckers Report entitled:
Is 10 MPG Possible with a Fully Loaded (80K gross) 5 Axle Truck? where the above are discussed in light of one O/O's experience.
Since big trucks tend to run 10,000-miles/month, the results can be quick as to calculated effects.
