Mazda 5w-30 also has a lot lower moly than it’s 0w20. I see that and in my mind the moly compensates for lower viscosity. It is a friction modifier but because it turns on with heat with its sulphur bonded atom is it also a EP that is not needed with higher viscosity? Sulphur has positive and...

For those that have this one… Does all foam maker pills fit this model? Went from great foam to poor. Needs a tune up.

I really like TW Flex.

The problem with corn ethanol is every year you have to till the ground which releases carbon. Switchgrass is what was on the plains just needs to be trimmed for harvest. https://farm-energy.extension.org/switchgrass-panicum-virgatum-for-biofuel-production/

Thanks…

Oil is not magic. But clean oil trumps all. Follow the operator’s manual and change often. https://www.gmc.com/bypass/pcf/gma-content-api/resources/sites/GMA/content/staging/MANUALS/6000/MA6525/en_US/2.0/23_GMC_Sierra_Sierra_Denali_1500_OM_en_US_U_84883874A_2022JUN30.pdf Page 341 Keep in mind...

Well… That shoots CAFE complainers here in the donkey.

Sorry… So you leak 1 quart every 1000 miles?

You can ask over here… https://forum.miata.net/vb/forumdisplay.php?f=15 I have a ND Miata.

So if it leaks…. Different than consumes oil. But if it leaks use high mileage oil.

GTL base runs like new Mobil 1 compared to the old Mobil 1.

Yep… hBN is #5 (boron) on the elements and Graphene is carbon (#6 carbon) Both elements can be formed to be abrasive but those forms are one atom thick linked sheet which slides well. (playing cards)

Here is Mazda’s factory fill UOA for a 2017 CX-9 turbo. https://bobistheoilguy.com/forums/threads/2017-cx-9-first-uoa-on-factory-fill.278000/

Moly uses sulphur and boron does not. They work well together. Moly works better when heated and hBN works at all temperatures. They are like playing cards that slide between two surfaces.

Hmmm… Guess you need to figure why before next week.

Thanks for your view. Everyone has a different view. Change for the better is inevitable.

That goes with tighter bearing tolerance also.

I found this informative about the goldilocks location of where the MOFT should be. https://kingbearings.com/wp-content/uploads/2014/10/Geometry-and-dimensional-tolerances-of-engine-bearings.pdf There is truth to MOFT at a given value is a optimum point... Read oil clearances.

MOFT is very important because at that point there is extreme pressures that hold up the bearing surfaces. That is where engineering comes in. https://kingbearings.com/wp-content/uploads/2014/10/Geometry-and-dimensional-tolerances-of-engine-bearings.pdf Oil adheres to each surface and the...
