Very impressive. If it is as good as their other products I might have to try some!

 

Good find. I use all amsoil oils in my engine, trans, and diff so I'll probably try some of this as well.

 

Looks to be a little better than ATE blue , i will have to give it a try. I actually checked the stuff out last time i was at the wherehouse picking up oil.

 

Remember ultra high boiling point fluids are very fincky and need to be flushed if you ever boil them and they suck moisture like a sponge so they need to be replaced very very frequently.

Like single use one race and they are done!

The lower the boiling point the slower they absorb moisture and change to wet boiling point...............why oem uses DOT3 to avoid punishing owners with monthly changes. OEM usually is good enough for street for 24 months.

 

All brake fluids are like that. Not just high temp fluids. It is recommend to swap out every 12-24 months. Even the OEM dot3. But do people do it? Not really.

And one race and they are done? I hope you are joking because I have kept the same fluid in my other cars after racing at MSR and it has been fine.

 

Some of the high temp brake fluids should be swapped after a few races as it loses its heat capacity if you exceed it.

 

After a few races yes, but not just one race.

 

Yh, I glanced at my flyer the other night. I have not had time to actually read it, but it is from amsoil. It has to be good. I am looking forward to hear some comments from you guys after a few races
