Read this slowly and carefully.
Oil... is just oil.
I got ten bucks that says it's easier to explain the concept of a standard deviation to a normal person than to explain to an Amsoil fanboy that the oil he pours through his valve cover isn't going to bring him (or his truck) eternal youth.Pretty sure that a lot of folks will not understand standard deviation but I agree with you.
Okay, here we go.First of all I prefer to use cheaper oil and change it often,but I will not agree that all oil is equal.I have used lots of amsoil in the past and one thing that will not lie is operating temp.Especially trans and diff.Put amsoil in and watch those temps drop.Just saying that for what its worth...

I personally dont think its rocket science,but maybe that's just me...Okay, here we go.
There are multiple sources of heat dissipation in lubricated mechanical systems. Interfaces between metal components that experience mutual "sliding" (bearing races, cylinders and piston rings, etc.) are one source, and we use lubricants to reduce the coefficients of friction at those interfaces to reduce the shear stress experienced by the components; this has the (generally positive) side effect of reducing heat dissipation at those interfaces because less mechanical work must be done to overcome friction (any work done to overcome friction is dissipated as heat). The other source is work done on the lubricant itself; i.e., in a differential the ring gear is turning and continuously mixing the gear oil. The rate of heat dissipation from fluid shear is proportional to the shear stress in the fluid, which is proportional to the fluid's viscosity. Ergo, for the same velocity gradient (i.e., amount of "mixing," speed of the ring gear, etc.), less viscous fluids will dissipate less heat. At the same time, the amount of heat dissipation at metal-metal interfaces will likely increase with decreasing viscosity, but not necessarily in a mathematically well-behaved manner. In other words, send me a big fat check and I'll fire up my CFD/FEA software and sell you a dubious answer to a very complex question.
The point is, a simple temperature reading is not a useful test of the relative efficacy of any lubricant.

I buy quality diesel oil thats on sale and use stockish style filter,,350k and still beating the daylights out of her.
Man. That’s a great feeling.I tried that but every time I drove my truck I got this overwhelming urge to go deep fry a turkey. Stihl chainsaw bar oil for me :thumb
I totally get it, my dads been in the timber business since he was born and I grew up in it till swerved off the rails and got into natural gas production. I love the smell of fresh cut sawdust.Man. That’s a great feeling.
Letting the Stihl chew itself through a tree and then stepping beck and letting it drop. Idk. Maybe a I’m weird but that’s a hell of a feeling.
