felt my hp somewhat increased because sometimes i feel the need of having a 'heavy feet' if you know what i mean... and comparing before and after change oils... i tend to shift faster because i was already hitting my desired RPM prior to shifting.. so from that my engine was taking easier to transfer power to the wheels then to the road thus a faster speed.

well, thats for my experience sa ride ko... but of course, iba din ang magiging experience for your engine.. iba-iba din ang mga reaction nila.. parang may sariling buhay. hehehe.....
thank you sir for sharing. i think i'll go for 5W now.

RP, redline, some motuls are group IV. some motuls are group V.
thanks sir for clearing those things up. will drop by your shop to get myself some RP.
