I've been told synthetic oil can cause more problems than it solves. I've heard it shouldn't be used during the a motorcycle's first few thousand kilometers as it stops the engine bedding in and that it can cause clutch problems as well. Is this true? |

For the newer bikes, fully synthetic will extend the bikes life, however with older bikes 20+years, standard grade bike oils with high Zinc contents are required. As the new oils have become more environmental friendly, they have taken out the 'good' stuff. New engines are designed to run without the 'good' stuff like zinc. One example is the rocker and valve contact area in the old Honda CB125 etc, The local pressure here is very high when you are pushing the motor and Zinc was added for this type of purpose. The new motors with valve buckets have a considerably lower pressures ( kg/mm2) and therefore don't require as many additives. |

Personally I always follow the advice I get from many mechanics who suggest that during the break-in period owners should use non-synthetic oil, and then switch to synthetic after the break-in period is over. It will not hurt the engine so it's a safe advice even if one day we discover it's complete nonsense... |
