Slippery track

[The Rustman]

Being a bit lazy here havn't got my blue book to hand.

Is there any restrictions in the regs about which engine coolants you can use or can't use. I know for sure the bikes will only permit water because an ethylene glycol based coolant is too slippery ?

I've never heard about any restrictions on coolant but I've not read the blue book cover to cover!

Cooling
5.10.1. Have any fluid carrying lines or tubes carrying
coolants through the driver/passenger compartment
painted red, and if non-metallic to be internally or
externally metal braided hydraulic pressure hose.
5.10.2. Screwed hose clips (e.g. ‘Jubilee Clips’) may only
be used in conjunction with a suitably swaged pipe.

Coolant type appears to be free, thanks for the link
