Just in case you were interested i arranged a discount for club members with Opie Oils, just select the Pontiac Owners Club in where did you find us section.

Thanks for that , i did use the discount when i changed the gearbox oil. Mot and 1500 mile run in service with robin on 15th Feb, might just add to it perhaps.
