"you have to be careful about making blanket statements.

it really does depend on the operating temp. range people are dealing with.

if you're in a high heat scenario doing a lot of weekend strip action, one lubricant made for one kind of use will become putty under a strained condition.

I'll give you an example:

we had been discussing gear oil for for trannies with clutch pack LSD's.

most people base their choice on the GL rating and API rated weight.

in some cases the operating temp of the gear oil designed for hard high heat racing applications were being used in street daily drivers. These oils were too slippery for the daily driven cars with LSD's and the clutches in the LSD would not grab...no LSD lock up when you need it. People then needed to add friction modifiers into these racing gear oils to get them to allow the LSD clutch surfaces to grab. Other people got cheaper gear oil that weren't made for racing and then found that the clutch pack grabbed better during daily driving. Did that mean the cheaper non racing gear oil is better than the racing gear oil? Of course not. One track day with that cheaper oil and the clutches in that LSD would be toast.


SO was it a case of bad gear oil or improper choice?

If you high rpm launch your car and powershift, is it fair to ask an OEM MTF to handle the heat you are generating?

This is why we need to be smart and start looking at what factors make a product good and under what conditions before we announce how great they are. It's about educating each other. It takes more work and digging and less superficial assessments. That's why it's so much harder to see these kinds of review. People have to get out there and get the facts and put it together. But in the long run you understand better. You understand WHY something is better. It's not an intuitive thing. When we don't know all the info, we rely on intuition and that works sometimes. But it'd be nice to link intuition (right side of your brain) with logic (left side of your brain) and have the 2 working together in nonduality."
