Have I been had?

Not as serious as the title sounds, but strange question.......

I was talking to a Ford Championship racer last week, (nothing overly special, only ST's) who swears blind on changing his gearbox oil for autobox oil. They run the standard Ford ST gearboxes, but he claims that Autobox oil is thinner, and free's up a little extra power that normally lost through the drive train?

Anyone heard this before, or is he spouting cack? Surely if this was the case, everyone would be doing it to start with?
Eco-emmisions and effieciency and all that stuff?

I haven't heard of that one before??

Yeah there's some truth in that but it does mean the box isn't getting as much protection as is needed.

I wouldn't try it in a JC gearbox that's for sure.

 

[Dan@SJM]

Iirc it's thinner but is upto standing higher temps and pressure and as such can make for a nicer change.

 

[Fred@BTM]

yeah i've done it before, the box doesn't last as long though!

 

[levaz]

looks like there's some truth in what he says then. They tend to keep a couple of spare boxes 'in stock' in case of problems so this probably wouldnt phase him.

I always thought autobox oil was thicker? Obviously not though it would seem!

So that's what happend to the V's box
