Mineral oils typically have a viscosity index of below 100 – This means that the oil thins rapidly with an increase in temperature. The higher the viscosity index the less the oil will thin (lose viscosity) with a rise in temperature. Good synthetics typically have Habothttps://www.blogger.com/profile/00146136551812334965noreply@blogger.comtag:blogger.com,1999:blog-3827122876960551099.post-35100674975352722492013-03-24T01:21:03.639+02:002013-03-24T01:21:03.639+02:00I have an Austin Healey 3000 with four speed manua...I have an Austin Healey 3000 with four speed manual gearbox c/w Laycock de Normanville overdrive.

Do you have a fully synthetic gearbox and overdrive compatible oil that would Anonymousnoreply@blogger.com
