    Good price genuine Castrol GP50 which was delivered very quickly. This oil was recommended to me by Phil Pearson after he stripped and rebuilt my BSA DB34 Goldstar.

    What can you say about Castrolbthat hadn’t been said before? First class oil. Why use lesser quality in a £60,000 car?

    The order was for 3 gallons, not 1. Happily 3 gallons were delivered satisfactorily.

    The best oil for BSA Gold star

    When I had my DB34 Gold star engine rebuilt by Phil Pearson (the Gold star Guru) a few years ago, this is what he told me to use in the engine, which has run flawlessly. The only problem it has is that it wet sumps when left overwinter. This is the next problem to resolve so am waiting to have answers from the Gold Star Owners Club who I have written to about this annoying problem.

  • The best available for the purpose

    This is the very best oil for vintage motors, which often have slight internal wear. It is the only oil I would use in my pre-War Ariel or 1950s BSA.

  • Good Classic Oil

    In my esprerience over a 50year period it is a very good oil for larger capacity single cylinder 'old school' racing engines. I have found it particularly good at limiting cam wear on Velocette OHC engines.

  • Good reliable lubricant

    I've used this product since 1961 in my Matchless G12 CSR gearbox. Summer and Winter - Eastern Mediterranean to Northern Scotland never a problem.
