well i also not feel engine knocking happen in our campro when using RON95, just the difference with RON97 is performance and ofcoz 97 produce more torque so more mileage.
what petrol brand u use ZenGTMM? i just use petronas since 1st day collect the car my SA fill full tank with pertronas RON95 and i feel petronas petrol suite campro the best
I have used bhp for my first tank, shell for 2nd, esso for 3rd and 4th tank.. Then partially will rm20 with shell when my tank ran almost dry and the car was choking a bit.. what petrol brand u use ZenGTMM? i just use petronas since 1st day collect the car my SA fill full tank with pertronas RON95 and i feel petronas petrol suite campro the best
So far what i can deduce is, bhp gives good power, best mileage among all 3 tanks. Esso gives best amount of pick up. Im staying in subang and every morning i go to college i can feel the difference.. Shell so far i dont feel good.. Engine feels heavy, even on the 2nd partial fill.. The revs like dont want to climb.. And mileage was poor. On my full tank of Shell i was travelling on highway 85% of the time.. Nvr speed more than 130/140 max.. Went to KLIA, then went to seremban and back from subang. Got poorer mileage compared to town driving..

How did u come to this conclusion from the video and facts given? .... if we dont consider those additive for friction modification...
basic physics .... should be burn hotter... or burn longer... means more energy ? isnt it?
I used to work part time data entry in NanoTag Malaysia. The one that they put nanotag into diesel. I was in charge of entering all those test data and results that were in printed form cos the softcopy was destroyed. There were at least 20binders of test and results from different fuel companies about their additives and emission standards and nanotags specification. I had to manually type into Word and save it as a softcopy. SO i got to read the reports too.. Man.. They were super detailed.. basic physics .... should be burn hotter... or burn longer... means more energy ? isnt it?
That time there was only Ron92 and Ron97. They did test so analyze emission standards from different fuel using 5 different types of cars (different CC and compression ratio). Thats how i picked up this knowledge lah..
If basic physics, burning hotter and longer means more energy release. But in a combustion engine, the mixture is aneamic (lesser oxygen so that the engine doesnt burn lean and overheat). Engine needs maximum energy to be transferred from fuel form to gas form. Thats why we need the mixture to combust, prevent excessive loss of energy in light form or sound form. As compression goes higher + cylinder head heat, petrol will combust spontaneously at a certain point. Ron97 is able to resist early combustion due to its more stable and slow burn nature, allowing the cylinder head to compress the mixture a bit more b4 it detonates itself too.
