Sparky,
Big 'way to go" using 10 w 30 oil in your rear end. Standard 80-140 wt is not needed for Bonneville and really is a hp eater.

I did not know this. Do you have any problems with the thinner viscosity getting past the Axel seals?

Is this ok in an early Ford banjo (3 miles max )

We run TDH with a little ER. Never had a problem except when we forgot to put any in. Lasted 4 runs (300+ mph) before taking all the teeth off the pinion.

TDH?
ER?

Stan,

You have a PM.

Transmission, differential, hydraulic oil (aka tractor hydraulic oil). Very light, I think about 5W. ER is Energy Release. It is an oil additive that really works in a myiad of applications. I think there is a thread about it somewhere.

ThunderSalt---so far so good---who would care anyway

sparky,

  does the same reasoning apply to 4 speed manual trans. ( w/ straight cut  gears ) ?

  what about engine oil ?

  the friction reduction makes a lot of sense. but, what are possible drawbacks ?

many thanks,
franey

I have no knowledge of the Tranny question---therefore no comment.

Not sure about other transmissions, but Toyota used a modified ATF iin the Getrag 6-speed (twin-turbo Supra) and way before that we used Dexron in Corolla 5-speed manual trans (around 1984-85).  That was the Front Wheel Drive model, by the way.  The trans seemed to hold up just fine.

We used to run ATF in rear wheel drive manual trans, for high altitude (super cold) winter operation.  It was the only way to get out of 1st and into 2nd when you had to leave the driveway and head uphill!  If you couldn't make the shift (with gear oil), you couldn't get back into 1st without stopping, and once stopped on the snow....you couldn't get going again!

I run 1/2 and 1/2 in my street roadster and it's been fine for 2 years.... and it shifts great!

Regards, JimL

When I found out S-10 pick-up standard transmissions used ATF I changed to it in all my 4-speeds and never looked back. In my Tex T101 I do mix in a little 75W gear lube. Good Luck
