4th and Reverse Gear Grind?
Not wanting to argue with you or your experience, but it did happen to me with brand new stock fluid 3 years ago (4th grind). I switched to pennzoil synchromesh. No problem since. I wouldn't call this a "waste of time".
I know some day I'll have to rebuild the tranny with new gears, synchros etc... but adding 3 years and 60kmiles is pretty darn good for a fluid.

When a trans grinds, the synchro is done. That's just how it works. The synchro is supposed to prevent and fight you so it will not grind. If it grinds, then it no longer has enough material to do its job. Using an oil that creates so much friction is just going to wear out other things which usually don't have a problem.
Just my 2 cents as I see many EVO trannies a day here. It may feel like you are saving money, but you are not. Our most expensive builds are from those that tried to run the trans as long as possible before finally repairing it. So many parts are gone by that point that didn't need to be.
Just trying to give accurate and helpful info to the OP. He is obviously free to do what he wishes.
Good luck!

Did you put all 150k on the awful fluid, or did you recently use it after it already had high miles? It's not fair to say a fluid got you 150k out of a trans when it wasn't in there the whole time. For some reason, many people do this and it makes for information which is not accurate to others.
What is likely happening is the Pennzoil is so awful that it is creating enough friction in the unit to allow the dead synchro to somehow work well enough to engage even though it is bottoming out on the gear. Instead of using the friction surface in the center of the ring (which has been long gone) the bottom of the ring is now the friction surface on the engagement plate. Using that oil for extended periods is going to cost you a lot more money down the road. Severe thrust, gear, fork, and bearing wear will be in your future. We see it here daily.

I don't use it to save money.
