    One of the points I was trying to make is this.
    With fuel consumption you are measuring distance traveled divided by amount of fuel used.
    I cant remember the details but there are three main aspects of a truck that effect this.
    Thermal efficiency , mechanical efficiency and wind resistance.
    Most losses are some or other form of this.

    There is a lot of the energy (Most) that is coming out of the fuel that is lost due to these factors.
    Only the remaining energy is used to propel your truck.
    I cant remember the figures but what I'm trying to point out is the following.
    If 5% of fuel energy is used to overcome rolling resistance.
    If 10% of fuel energy is used to overcome all forms of other mechanical losses.
    If 25% of fuel energy is lost to thermal losses.
    If 30 % of fuel energy is used to overcome air resistance/drag.
    This leaves only 30% of fuel energy that is used to move your truck.

    What this means is that if you are able to drop the mechanical losses from 10% of total energy consumed to 5% energy consumed this does not translate to a 5% increase in fuel mileage.
    This 5% gain can now be utilized to move your truck , thus increasing this value from 30% to 35% of the total and that is an increase of 16,67% in fuel mileage.

    This is the reason that something that only consumes 10% of the energy if reduced can translate in to a larger % in Fuel mileage gain.

    I will admit I am not a scientist. I am only a truck driver that has posted every fuel up with odometer readings to compare before and after making changes.

    I have a dedicated run where everything is the same on roundtrip runs several times a month. The only variables is traffic and weather that affects these runs.

    Now you can go by my actual numbers that shows exactly what difference the changes made or you can make up estimated numbers trying to argue with my facts.....the choice is yours!

    You can verify all my numbers by logging into https://mygauges.com and go to "Dice.s Truck".

    Every change I have made since January this year is there to prove it.

    My average for August so far is 9.39 MPG compared to July being 8.21 MPG and June 8.15 MPG. Let me add my average for February that was the first full month of recording fuel mileage was 7.06 MPG before I added the PP turbo, PP Manifold, Fleet Air Filter and MicroBlue.

    Dice , I'm not sure you are directing the "argue with my facts" at me or not.
    If so I don't know why.
    The issues I am pointing out actually offer some explanations as to how notable improvements in mileage can be made by small gains in efficiency.
    This is in response to the opinion that gains you post are impossible given that the surfaces you treated only account for a smaller percentage of power drain that the increase in mileage you are claiming.
    I was showing why this not only possible but how things actually work and why they work that way.

    Any way keep posting but lighten up a bit , you will get flak for your efforts as much as you get praise.
    I personally commend you for your efforts and thank you for sharing your findings.

    I found the article below after a quick google search for MicroBlue and found it to be interesting.
    A solid film lubricant coating that has proven to be very effective in preliminary tests is the MicroBlue® tungsten disulfide coating. This coating is patented by Material Technologies, Inc. and is provided by the same company. This coating is applied by a low-cost atmospheric pressure particle impingement process. The coating produces almost no dimensional change (less than 1 micrometer) and is applied at ambient temperature. The MicroBlue® coating provides a low friction surface via two mechanisms. One mechanism is the inherent lubricity of the tungsten disulfide thin film on the surface.4 The other mechanism, which is perhaps more important, is that the tungsten disulfide acts as a wetting agent for hydrocarbon-based lubricants because of their affinity for the coated surface which causes the lubricant to more effectively wet the surface. The high durability of the coating is most likely due to the patented application process in which the tungsten disulfide is mechanically bonded to the surface by filling in micron-scale depressions in the surface.
    To evaluate the coating durability, Aerodyne Research, Inc. (ARI) recently had block-onring tribological wear tests performed on standard and MicroBlue®-coated test specimens (Figures 1 and 2).
    [​IMG]
    These tests dramatically illustrated the ability of the coating to provide low wear and friction, and in particular, demonstrate its ability to maintain a lubricant layer between surfaces under very high stress conditions. The tests were performed by Falex Corporation using their Blockon-Ring test apparatus. The test conditions were selected to be somewhat representative of a diesel engine crankshaft bearing under very high load. The test conditions were: 2000 rpm, 100°C, 150 lb force, and 100000 cycles (40 min). The Falex H60 block (SAE 01 Tool Steel, Rc 58-63 Hardness, Ra= 4-8 roughness) and S10 ring (SAE 4620 steel, Rc 58-63 Hardness, Ra= 6-12 roughness) were selected for the test. High quality diesel engine oil, Castrol GTX 20W-50, was used for the test in which the ring was partially submerged in the lubricant. Tests were performed for the standard H60 block and S10 ring as the control test, and for the same block/ring combination after being treated with the MicroBlue® surface treatment. Images of the specimens are presented above in Figures 1 and 2. The data sheets for these tests are presented in Figure 3 for the control test and Figure 4 for the MicroBlue® treated test.

    A legendary block on ring test that is used by every snakeoil seller...

    If some part of your truck is stressed beyond normal lubricant film strength there's something wrong with that part or the lubricant you are using.

    Timken also have a similar test.Basically the film strength/shear tester.You can take any oil even cooking oil and get great results just by adding a EP (Extreme Pressure ) additive like chlorinated paraffin.If this Micro Blue achieved this result with out any snake oil then it is impressive.
    A lot of gear box and diff oils have EP additives as does wheel bearing grease. If you had a surface that could stand extreme pressure with out EP lubricant it has to be interesting.

    My Opinion is the big difference in oil additives and MicroBlue is MicroBlue is a polishing process treatment directly to the surfaces with the coating bonded directly to the metal surfaces instead of floating around in the lubricant that may never get on the metal surface at all or maybe in a small quanitity that may not remain on the surface.

    You are right but those have nothing to do with lower friction. EP additives are there to protect from short term shockloadings.
