Cheap oil can be mean by mineral oil which come when u buy a new car..the factory only use a cheap oil coz this efficient for the engine breaking period..thats why after take from dealer can't simply2 rev bcoz the piston ring and cylinder bore still have restriction and cause ur engine burn and noisy..commonly for 1st service is 1000km just to throw out your abraded metal that in breaking period time..summore use super good full synthetic oil(0w-30) also can cause engine burn due to high restriction because the oil is too thin and can't lubricate all the parts properly(engine hot&thin oil and can be burn together on power stroke)..so,use as recommended for it unless u want to experiment it ur self..can u explain the meaning of cheap oil?
Actually, contrary to popular beliefs, mineral oil offer better overall protection than semi syn / syn oils. The oil is much thicker at operating temperature compared to synthetic oils. It also cleans up residue in engine even better.Cheap oil can be mean by mineral oil which come when u buy a new car..the factory only use a cheap oil coz this efficient for the engine breaking period..thats why after take from dealer can't simply2 rev bcoz the piston ring and cylinder bore still have restriction and cause ur engine burn and noisy..commonly for 1st service is 1000km just to throw out your abraded metal that in breaking period time..summore use super good full synthetic oil(0w-30) also can cause engine burn due to high restriction because the oil is too thin and can't lubricate all the parts properly(engine hot&thin oil and can be burn together on power stroke)..so,use as recommended for it unless u want to experiment it ur self..
Errr.... i do it every 10k no problems for me. Millage is pretty decent too.... every 5k is like the old Satrias man which i used to own and the wear and tear is hopeless in that one. Neo CPS is far easier to live with.semi-syn will do well for CPS..... ++ To change oil every 5000 km is a must in order to maintain the smoothness feel in ur engine....
