I'm writing this review one month of using it in Suzuki Gixxer, after 7 says the bike was not starting like it used to, I had to use choke, then started regular visits to mechanic, replaced air filter, spark plug, drained carburettor and even serviced the carburettor, with little success at last decided to change the engine oil within 30 days and now running like usual. So I conclude this 900ml pack is some duplicate/fake oil, I don't think Castrol would make such worst product, even with cheaper engine oil my bike is well performing.
