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.Verified purchase: YesCondition: New

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.Verified purchase: YesCondition: New

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.Verified purchase: YesCondition: New
