Very interesting find Casper , tons of stuff on youtube . Mobil 1 , or any oil for that matter talking
very long change intervals IS a joke to me , mostly due to my localle.
His "kitch'n tests" with the fridge and coffee pots - interesting , amusing , I don't know for sure how actually representave or applicable to late engines as far as the "wear test" , which all the tests were very close.
That test or variations thereof have been demonstrated and maybe "Shilled" for Eons
Car bearings ride on the film of lubrication ( SAE designed ) and I'm not convinced that this very close comparison and outcome of a HARD & SHARP object under severe force to BREAK THROUGH and PIERCE the designated oil film is anything to worry about in my car , unless like CUTTING oil shredding the test peice to ribbons is what's demonstrated of the oil under examination.
I'll joke that R -Purple is just Mob1 with purple dye - resold for a few dollars more
I'm gonna joke here that Schaeffer's is 'tantamount' to Mobil1 with a tablespoon of Myst. Oil,
selling for SEVERAL dollars more , although I myself usually don't take the cheap way out on the vehicles.
Casper you always seem to do your "homework" , and I appreciate this interesting "Tuber" to be watched in future . Will always respect your input.
As far as looking past Mob1 , I'm looking at and learning more about the Pennzoil Ultra Full Syn.
Says synthesized from Nat. Gas ?? Funny everyone I knew and me considered the Dino Pennzoil of the 70's & 80's to be ( Consistency of ) WATER COMING OUT of the can

(had Cahd-bord cans back then).
