個人覺得機油對於這種小汽缸引擎的馬力提升不大..
以摩擦力來說..活塞的大小和走的行程遠小於汽車或重機(不一定)..
能減少動力損耗有限
我記得國外有一篇文章騎乘重機分別使用motul 5100、7100下去做測試
7100的換檔滑順感、加速感、尾速都贏5100 (同翻數)
還有一篇文章是賽克隆針對機油黏度..測試制動馬力
測試機種Honda Blackbird 1100cc
Pro-R 15W/50
Max power 127.9 BHP @9750 rpm
Torque 75.8 ft-lbs @ 7300 rpm
Pro S 5W/40
Max power 131.6 BHP @ 9750 rpm
Torque 77.7 ft-lbs @ 7400 rpm
Pro R 0W/20
Max power 134.4 BHP @ 9750 rpm
Torque 78.9 ft-lbs @ 7400 rpm
但是抗磨損與大馬力輸出是不可兼得的..
Am I recommending 0W/20 for Subarus? Well, perhaps not! The Pro S 5W/40, which is a ‘proper’
PAO/ester shear-stable synthetic, will look after a powerful engine better than a heavier viscosity
‘cave at the back’ conventional oil, and provide a useful few extra BHP.
