New Pennzoil MTF?

I wouldn't touch a Synchromesh typically of KV@40*C of 48 cSt/KV@100*C of 10 when a spec'ed 75W90 GL4 would have KV@40*C of 90 cSt/KV@100*C of 15.6 cSt.

If Redline 75W90 MTF is 'unpleasant' for whatever reasons, I'll seek out other brands of 75W90 ...


You wouldn't but many manufacturers do just that. VW does it with all of its MTXs.

Unfortunately my priority in oil selection doesn't synch'ed with manufacturers' at times ......
I would say Thank You .... so much for CAFE and/or FE.
No offence meant.To each his own.

Most manufacturers are going to the low viscosity MTFs for better shifting in the cold, not MPGs.

I prefer Amsoil MTG over Redline MT90 for long lasting.

The label text is: "API GL-4 MANUAL TRANSMISSION OIL"

There are two large prints on the label: large letters Platinum Gear Oil front and center, and large letters Gear Oil on the right side.

Few cars use gear oil in transmission, but I couldn't use it in my S2000. I either use Honda MTF or Pennzoil Synchromesh, if they make Platinum version will be better.

Will the better cold shiftability using thinner MTF result in more transmission wear once it's hot?

Redline's PSF chemistry could be slightly modified to make a dedicated LV MTF.



YES, EXACTLY!!!

Even SOPUS and/or XOM could do this as well.

I'm sure this Pennzoil Platinum Gear Oil is rebranded
Shell " Spirax S4 G" 75w-90.... GL-4

It seems a no brainer for Shell to add Spirax S6 GXME 75w-80 GL-4
under the Pennzoil brand as well.

Why don't you guys write to them asking/demanding LV MTF ? Telling them the reasons why you think LV MTF is needed.

No. Manufacturers use it all over the world regardless of climate. High HP applications are obviously a different topic.

Manufacturers can't be God of Wear , right?
A wear is a wear ......
and Monster Manufacturers want us consumers to believe there is such a thing as 'acceptable wear' ....... which are easily preventable without much human effort ....
by sticking to existing/previous well proven viscosity grade in use.

That is such a close minded stance. Things improve over time. Why settle for your "acceptable wear" when you can likely do better with improved products?

 

[zeng]

Oh no .....
I'm keeping away from 'acceptable wear' expounded by Monster OEM/CAFE , by sticking to 80W90, 90 or xxW110(or thicker) ..... in transmission systems ........
while enjoying the benefits derives from supposedly 'improved' add packs/base oils etc.

I have written to all three companies and it has fallen on deaf ears to date. I have even offered to consult on the formulations if necessary.

Obviously someone at Shell/Pennzoil listened when it came to
offering a gear oil product such as the Platinum 75w-90 Gl-4 spec.
I've been pretty vocal about it, I think Amsoil, and Redline are good products but I still tend to trust the major companies more when it comes to testing, and development. I'll be buying
this Platinum 75w-90 GL-4 for my VW Golf.

I have also personally spoken to Dave at Red Line, and although he sounded doubtful of this even coming to fruition, he also did not completely rule it out of the realm of possibility.
