Don,

I have heard that; thats why 3k miles ago I ran dino oil that was the same weight as the swepco. I do not remeber the particular brand, but I believe it was the number 2 recomened here.

Last week when I took it the garage I wanted to change the gearbox oil again, to be sure everything was clean. Previously to that oil change the gearbox was bad, and I thought it would need to be rebuilt. Jerry, the shop owner, wanted me to try the M1. He said he had good luck with it, even in 915 gearboxes. I decided he looks at more of these in a day than I look at, so I let him. I don't know what weight M1 oil he used. He put it in took the car for a spin and said the gearbox felt outstanding. So I took it for a spin and it really felt leaps and bounds better than before. Keep in mind it felt dramaticly better when I changed the dino oil before.

Bill - I did play with the shifting a bit. I noticed a few things that I like. The gearbox shifts better when cold. Before the gearbox would get better as the car warmed up a bit, now its much smoother at initial start. Shifting faster works a bit better than before, it feels the way it did with the dino oil; a bit stiffer. However with the slight delay it feels almost silkie smooth. I was suprised to say the least. At normal shift speeds, for the 915 gearbox, shifts outstanding.

The main reason I posted this story is when I asked the last time I was told to try dino oil, and I did. This time I took the mech's reccomendation and that was excellent. I was suprised and maybe the parts in my 915 gearbox have woren to the point the M1 worked.
