Ya can't win 'em all.   

Damn if that ain't the truth ...

All of that and didn't make a ripple. I think from here on out I will just observe.

Even F. Lee Bailey lost a case once in a while. Just one question to put the cherry on top: why were you trying to sell me on using a gear oil that has a known substance that's harmful to brass synchros in it? Or a much more expensive alternative when GL-1 is all that's needed? Just because something is modern doesn't mean it's good for every application.

Dobie,

No. 1 - The product is in no way harmful to copper alloys.

No. 2 - If you can't figure it out with all the TECH presented, there is no further use of my trying to get it across.

Have a nice one.

In a previous post I added a link to the people who deal in OD parts and their expensive oil. They stated not to use GL-1 tractor oil, why that is I have no idea and I never called them to find out why. Use what ever you want, it's your car..

If you're talking about the Redline oil I'll agree that it can't harm the synchros since it has no sulphur. The only other advantage I see is it has a friction modifier to aid shifting when cold. Since I don't drive my car much during the cold months I see that as little benefit, considering the major price difference. In the warmer months the first few shifts are slightly notchy, but that goes away within a mile of driving. Also, the OD requires a certain friction coefficient to operate properly, which is provided by GL-1. Redline's friction modifier(s) could conceivably cause the OD to not function properly. If you have a vehicle with BW overdrive I'll let you be the guinea pig.

... why can't the boy learn ...?

Jim,

The only link in one of your posts I see shows the vendor recommending GL-1 only. Did I miss something?

... hmmph ...

Imagine that. Kind of hard to figure it out, isn't it?

OK, so it improves cold shifting. What about the OD? I want to see independent real world testing and data.

... you're quick ...

I want to see independent real world testing and data.

I doubt anyone would take the time and expense of what you are asking. Why would the upgraded lubricant have any adverse effect on the OD section, other than better protection?

GL-4 is natural progression as is multi-grade detergent motor oils.
