I have a question it may be answered but I don't remember seeing it - what is the payback time for a conversion to MB bearings?

The parts cost $950 for tractor and $650 for trailer. $1600 for parts and let's do 2 scenarios, you do the job yourself and you pay $1000 to have them installed. We will also assume diesel holds $4/g.
$1600:
If your mpg now is 5 mpg (0.80) goes to 5.7 (0.70), then payback = 16,000 miles
If your mpg now is 6 mpg (0.67) goes to 6.7 (0.60), then payback = 22,857 miles
If your mpg now is 7 mpg (0.57) goes to 7.7 (0.52), then payback = 32,000 miles
If your mpg now is 8 mpg (0.50) goes to 8.7 (0.46), then payback = 40,000 miles
$2600:
If your mpg now is 5 mpg (0.80) goes to 5.7 (0.70), then payback = 26,000 miles
If your mpg now is 6 mpg (0.67) goes to 6.7 (0.60), then payback = 37,142 miles
If your mpg now is 7 mpg (0.57) goes to 7.7 (0.52), then payback = 52,000 miles
If your mpg now is 8 mpg (0.50) goes to 8.7 (0.46), then payback = 65,000 milesRedForeman and Dice1 Thank this. -
Looks about right to me. Of course, if you're getting above 7.5 mpg before microblue bearings, a 0.3 mpg increase is huge at that level. It's hard to find fuel economy savings that large once one is up in that region.
Frenzy Thanks this. -
I'm curious if after an inframe with MB you can use the new 10-30 oil instead of 15-40. This will increase fuel mileage. Also can lighter oils be used in trans and rears?

Don't know about mb , but cat has been recommending 10w30 in the acerts for a couple of years. Unless your in Death Valley ....

Micro Blue: Im going to buy/try the treated Wheel Bearings.
I'll need to know this products real value in MPG increase/decrease.
First, I need to established my trucks pre-micro blue treated wheel bearings MPG, taken from at least 3-4K gallons of diesel fuel purchases. (idle time, dead head, variable loaded weights...hauling a 53' reefer trl.).
After I've install the treated wheel bearings, then I'll follow up by posting my results...ANY CHANGES, +/- to my trucks MPG at 1K gallons, 2K gallons, etc...up to 5K gallons of diesel purchasing.
(If, im missing something add a note...I work hard all day, and, don't get involved with starting Case Studies.)
A description of My Truck is: 2006 Freightliner Columbia, MBE 4000, auto trans, smart shift 10spd. Tires are Michelin Lo-Pro 22.5. (new tires, using balancing beads.). Pre-Micro Blue Wheel Bearings Avg.Mpg @ 1300 gallons, 6.62 MPG. I still need to gather more data on my fuel purchases before the treated wheel bearing purchase.

Thanks for the info, I can see the pay back. I have to ask a follow up,
have these been tested by any lab or some sort of controlled test with some standardized testing for comparison? -

Do you own the trailer also? I would point anyone to do your trailer axles first. I saw an immediate .4 mpg gain from doing 2 axle reefer. This was after i did my 3 axle tractor and saw .3 gain. Tranny and rear ends are on my list. eventually the engine when it is time.

This includes alot trucks with Microblue modifications documented.
