One thing i'm noticing with the shockproof heavy is that it does take longer to "warm up" compared to the RP as the weather gets colder (which of course makes sense), though its only a couple more mins or so.

It isn't a hassle though, and the extra time waiting for it to get up to temp is worth it when compared to the durability it offers in the long run.

 

Correct - but I did that to try and get you to give us the facts - it worked

The thing that the facts did prove is that LW SP had nothing to do with your failures - which was implied in your original post .
From all this one could make the statement "LW shockproof is not the best oil for long life of your transmission - but under extereme conditions these transmissions tend to suffer catastrophic failure rather than gradual wear ,so you are probably no worse off in using LW "

What do you think Team ?

 

I didn't bother to go into the experiences of the serious RX-8 race teams. Frankly, what oil you choose to run is no concern of mine.

 

Just trying to get a discussion going so I can make an informed decision .Don't really want to Drain the oil out and replace it for no good reason .
