the lube spec and a better lube supplier has proved

have made a major error on the honey lube specs)

I think the onus of proof is on the aftermarket
supplier to prove that their lube is better.I have yet
to see another suppliers test data that shows such
information,either by testing or chemical formulation.
Just a thought!





Good points, Pete, and more info that I'm sure I read but either missed or forgot.

I did not nor do I now defend MTL, but I still think we have precious little to go on to condemn any fluid.

Still, if I were just looking at specs, and had never heard of CEG, I'd pick the MT-90 over the MTL based on it at least having the correct viscosity.

I checked with my local Ford dealer on the Honey, and it's $21.60/quart. I've emailed Bill J today (Friday), but I don't expect a response until next week. Where is anyone finding this stuff for $15?

I also appreciate Terry's position, but Ford and other OEMs will do things sometimes that are just a little shady. For instance, they will "spec" 5W-20 synthetic motor oil and then charge extra for it at the dealer. Truth is, any 5W20 synthetic would work in that application. Many people believe that in this case, any 75W90 Gear Oil would work just fine, but Ford creates some arcane "spec" that very few aftermarket suppliers will bother to cross-reference. Sure, it might be the "best" but that doesn't mean all other fluids will wreck your transmission.

Anyone have any real experience with the RP Synchromax? Or did I miss/forget that, too?
