I am going to change to Castrol SRF and was told that the Motul 660 is better than the newly formulated Castrol SRF. I was also told that the old SRF was better than Motul 660.

Is anyone familiary with the newly formulated SRF?

Didn't know it had been reformulated.
Do you have any info or links?

I was told by a vendor who used to carry SRF. That vendor no longers carries SRF because of the alleged inferior new formulation. They now recommend Motul 660.

Not sure if I'm getting BS here but I have high regards for this vendor. So I'm just trying to find out what is going on.

It is starting to sound like BS, but I'm checking into it. I'm friends with the Brand Manager for non-oil BP products in the U.S. He conveyed to me that they are switching production facilities, but is not aware of any formulation change. He said he'd look into it to be sure. So stay tuned...

The new MOTUL 660 is good. Castrol SRF better. SRF has higher wet boiling point than 660. I guess when you look at the ratio of race cars in GRAND AM or ALMS that run SRF, it's almost all the teams.

Theo- Yes, I understand all about the difference in boiling points, particularly the disparity in wet boiling points. But my question is different. The question is whether or not the SRF formulation has changed. I think there is a general consensus that SRF has been the best fluid.

I call BS. Motul is a fine brake fluid, no doubt...But it ain't castrol SRF!

10-4. I read the question better now. Brain fade on my part.

I have been using Castrol SRF in all my race cars since day one and I have had consistent top notch experience even with my latest SRF can Feb 2008...
