Dear all, hi i just wanna share some good products wit u all. Have u all heard about PowerZone oils? It's not related to PowerZone Performance shop. I've just tested their product call Metal Conditioner and also Petrol Treatment and found that the product was superb!! No joke.. It's like my engine was completely changed! I was like wow... Now my engine is very smooth and also less noise then before. Rev also much more better at the midrange rpm. Going up the hill was better also. Normally i would used 2nd gear to go up the hill near my house. Now i can used 3rd gear without knocking or pinging. They are fews of the sifu here have ride my car before and know my car spec. AE92 Silvertop manual. Maybe some of you guy's might not believe it for wat i've say here. But if u all wan. Demo is available for u all to see how effective the product is. I'm actually helping my brother in'law to test out the product na d found out that it's done a very good job to my car. Now i'm very happy to drive it around. If anyone interested pls pm me for the detail and pricing. Demo is arrange able. Butt dyno is proven to be better.
