Re: Oils

[Alan Lambert <gerard@xxxxxxx>]

At the Monterey Historics, I bought some Motul synthetic from the Motul 
rep ( 2 for 1 pricing). The rep claimed that the esters used in Motul 
were not used by other "synthetics" which were not as "synthetic" as is 
Motul. He claimed far better performance and viscosity regulation, 
especially on the track. Even though you work for Castrol--is there any 
technical support for this claim?--Motul is more expensive than the other 
synthetics, but if worth it, I'll continue using it.
