We used normal mobil 1
If you thought that all your water pipes and rad were upto it you could fit a stronger header tank cap a 25psi one, this would allow the system to store more heat without increasing the temp.
PS, nice set-up patch under the Festa.

Cheers,
but i'm not happy running a cvh at those temps, as i've had 2 h/g's go when over 98oC.
i have a 18psi cap on there at the mo (tested) and it does start to leak at the end of a track session
ps, thats my old setup patch, i now have turn plates. But will be re leveling the garage when i get round to it.

My cossie does 92oC dueing 30oC ambients, and 30min+ sessions.

i tried many places to read the coolant, and i found the most accurate, with out getting heat soak from the head, is the lower pipe on the Stat housing going to the oil cooler, about 50mm away from stat.

once you flushed the system, does the fan cut in and out at the same points on the gauge?
