Don't cheap out on wear protection.
Both Pennzoil Synchromesh and Valvoline MTF should be available locally.

I have used the Pennzoil synchromesh and it really didn't shift any better than the mercon

Then it may be the transmission design that is the cause of your poor shifting.
If that is the case, acceptable shifting or not, Pennzoil Synchromesh or Valvoline MTF would be better than any ATF.

yea I know what u are saying, I think the trans is a little worn (165000 miles on it) and it never made sense to me that they make a manual trans that uses atf anyway. I know its for mileage and stuff but like some of the replies said it don't have much protection. thanks for all replies

give it some time, your syncros may still be slick from the ATF? That was my experience in my F250 of the ATF spec years, it slowly got better, snd then it really smothed out when i changed it again.
I even went to MT-90 this summer as an experament, worked awsome, but as the temps dropped you could tell it was too thick before it got warmed up as I drove. I have tried pennzoil, valvoline, and amsoil Synchromesh/MTL and all work much better than ATF ever did.

That may still be too thick.
Try Royal Purple Synchromax, or Valvoline MTF, or Pennzoil Synchromax. All would better than any ATF.
I had a '95 F150 with the M5OD and tried Mobil 1 ATF and Redline ATF but when I put in Redline MTL the transmission shifted the best ever. Before that it was notchy.
But the Ranger is a different M5OD, I think it is the M5OD-R1. I have a 2001 Ranger now and put in MTL when I bought it 35,000 miles ago. Someone told me I should not run MTL in the Ranger because it has carbon paper liners on the syncronizers.
When I had the M5OD in the 1995 F150 I asked a Ford service technician if I would go with a 10w30 or 10w40 motor oil and he looked into it and said it would be okay but nothing thicker. Redline MTL would be about as thick as a 10w30.
I actually put 10w40 motor oil in my 1984 F150 at the recommendation of a repair shop. They said it would shift better in winter. That truck ran fine on the 10w40. Funny because you would think the transmission would have chewed that multigrade into pieces. It was 1999 vintage motor oil.
