Pennzoil syncromesh GL 4

Does anybody know where to get Pennzoil syncromesh GL 4? Is it still made?

Napa, advanced, autozone, amazon all list it on their websites. Are you not able to fine stores with it in stock? Valvoline Synchromesh essentially the same as the pennzoil stuff, I run that in my 97.

Most places have GL 3 but i has looking for GL 4. Does somebody know the difference?

Never seen GL 3, usually all you can find is GL 5. I've had both Penz and Valvoline Sycromesh rated GL4.

Yeah I should have specified, that's why I'm running the Valvoline sycromesh in my 97 because its easy to find and GL4 rated. Thanks for clarification jettawreck!
