So my question:

Is Redline MT90 still good to go for the standard (not syncro) manual
transmission? It seems so from all the reading I've done, but the truth
seems awfully obfuscated. And - on the standard van - is the Swepco
simply just a leg up?

My van is up for a gear oil change and I would like to know. Seems like
i have used MT90 forever.

Thanks,

John Rodgers
