so far i have tried torco SR-5 racing oil on my putra, and i'm happy of the result. it make muah engine feels lighter no sluggishness when floor on the accelerator, highly recommended for those car enthusiast who keen for performance. v and for those who is looking for a cheaper alternative u guys can try SR-1 and one of my friend have tried TR-5 semi syn, he say it is better than what he expected as a normal semi syn.

my friend have lots of experience in automotive stuff, so if he say it is better compared to other semi syn, then from my point of view i will say that it is good, you can try it out and get the feedback yourself. then you can tell me how it is after that cheers. v
