My Z200 need to be change oil again. I'm thinking of what will be my next engine oil and here's my alternatives.
There's always the Big three(commercialsm) when it comes in Engine oil.
1. Shell
1.1 Shell rotella Diesel Oil
2. Petron (Currently I used their engine oil after the break-in period and not satisfied. Maybe petron oils are not designed to perform in motorcycle from china)
3. Caltex
4. Castrol
5. Duckhams
Engine oils are factors on how your motorcycle performs. The life of the engine depends on the engine oil it using. It must sustained the heat created by friction the between the rods and bearings inside the engine.
