1st) pls dont say every car is good/god car/best bang for your bucks/Very interested/worth it

If so why you are not driving it as your daily ride

just highlight the bad point as well... like the some case of HR-V good good good.. in end test drive sluggish

second minus or reduce your portong fanboyism

famoust in /k/ for that

a blessing in disguise huh...

to do a real control test, you need to consider the variables
in this case,

fixed variable/control - the engine of the car basically same performance and spec

non-fixed/test variable - RON 95 or RON 97

His method of review even by engineering standards is rudimentary, unless the driver is a robot no one have the same driving habit.

he claimed tat they switch drivers along the journey. This actually make the result even worse because now u are swapping different driving habits on all the tested vehicles which theoretically increased the randomness of the result. If one driving drive all the way until finish, at least he can claim consistent result by assuming tat one person have the same driving habit all the way. Then go to the next car and drive the same way as before. (More credible than swapping drivers)
Now u are swapping 4 different fellow in one car an expect a consistent result?

what he should do on in his so call real situation test is employed a dyno tester machine.. No not the kind tat improve your engine performance but rather the lab dyno testing used in university mechanical lab or engine test plant (both proton and p2 have it )

this is small lab type for university students to do lab test


And this is better dyno enginer performance (K&N)


I am too lazy how to explain how it works but it can be used to test diff fuel type and engine performance

Publishing the result based on control lab test is more credible than i drive on road and here is my result. If u are writing scientific paper and this is your methodology, the professor will laugh and throw your paper into the bin.

I guess u dont know really how RON number really works
For higher ron fuel, to prevent knocking retardant are added in which normally longer chain of hydrocarbon into the fuel to prevent the fuel from self ignite. That the additives you are talking about, there hardly any performance additives

If you want more power, you do it by adding higher octane fuel not RON. like pure ethanol, hyrogen etc etc but at the risk tat your car might explode because it not designed to operate in such high energy environment. Baciscally, the more flammable the fuels the better it is, the more power you can gain per litter of tat fuel. To calculate "scientifically' is by looking at the otto atkinson miller cycle etc the car engine is based upon. Again, it took me 4 years to learn about and I am lazy to explain it in details those themo cycles

adding more variables make for a more inconsistent result. The fixed variable should be the driver but instead it become the test variable as well

In retrospect to your answer, Public uni rent those equipments for a reasonable fees for a valid reason
UM, USM, UTM and any respectable university mechnical lab will have it and it available for public use

The only thing you have to do is write to the dean and explain why you want to use it.
Of course, it will be more difficult to have those High performance lab like the one used in P1 and P2. The main reason why it difficult because engine fuel consumption is a closely guarded secret

at least I better than some wikepedia warrior that think they know everything by reading wikepedia

nope.. i personally pump ron95 just because it cheaper
The reason why 97 is more expensive is because it marketed to high performance vehicles meaning more strict quality controls which inversely increased it base line cost. The strict quality control is just better filtering and more constant quality lab test. Again, it just marketing

If want more power octane, you should ask to petronas shell etec to introduce ethanol fuel mixture, then you can get better power per litter plus cleaner burning fuel.

If you, you can ask him to contact me and i will try to ask for him for a equipment loan at either of those university

Of course he have to pay because the technician would have to set it up, It a pain in a ass to set up anyway


well, if can natural gas is better fuel if you can cramp more gas into the combustion chamber meaning higher pressure

sadly, NGV run on reduce pressure environment to comply to safety requirement

significantly lower

last time a while ad berlambak on car resale value

now almost kosong 4 or 5 comment perday.. he have it coming
