I know many of Malaysian motorist are complaining the lack of performance of RON 95 petrol since RON 95 has displace RON 97 petrol as the main stream petrol. RON 97 is now the premium petrol. Since RON 95 is RM 1.80 per litter form 1st September 2009 and RON 97 has increased the price to RM2.05 per litter, most of us has to tolerate with lower grade petrol due to budget constraint.Ironically, many developed countries do not sell RON 97 petrol. In Singapore, only RON 92, RON 95 and RON 98 petrol are sold.
I do not want to compare RON 97 with RON 95 petrol. No point actually. Even you are complaining but you will still using RON 95 due to the lower price. So, my study is comparing different brands of RON 95 petrol.
Car: Proton Iswara 1.3 Manual, year 1999
Route: KL, PJ, Shah Alam with almost 100% city drive.
Driving style: economy driving. Seldom press the pedal hard except overtaking. Not a racer
Note: Each time I will fill the petrol until full tank
1. Brand:BHP Infiniti 2x
Total cost: RM56.81 or 31.62 l
Distance: 440km
Fuel consumption: RM0.127/km or 14.16km/l
Remarks: Quick, smooth during gear transmission (from low to high). Engine noise is OK, not noisy but you still can listen it. It is exceptional when pick up. I am satisfy with it.
Grading:8/10
2. Brand: Caltex Techron 95
Total cost: RM55.94 or 31.07 l
Distance:421.7km
Fuel consumption:RM0.123/km or 14.68km/l
Remarks:When I start my engine, it is very quiet. It is quiet and smooth even during the low gear transmission. Engine noise is lower than BHP infiniti 2x. It is powerful when pick up. Almost as powerful as BHP petrol. No noise even at 110km/hr. A better fuel consumption as well.
Grading:8.5/10
3. Brand: Shell Super 95
Total cost: RM51.71 or 28.728 l
Distance: 429.5km
Fuel consumption:RM0.117/km or 15.336km/l
Remarks:I have change a new set of tires in this study. This is a very bad experience using Shell. The engine is very noisy even when I started my car. The noise of engine is noisy and rough when changing gear. Most remarkable is I hardly pick up to 110km/hr as the engine is so noisy. I will avoid using this fuel. I will reserve my view of fuel consumption as different set tires is used.
Grading:5/10
4. Brand: Petronas Primax RON 95
Total cost: RM50.41 or 28.006 l
Distance:513km
Fuel consumption:RM0.123/km or 14.618km/l
Remarks: Ordinary pick up but much better than Shell. I still heard some noise form engine when I start my car but it is acceptable level compare with Shell. Easily pick up at high gear but lack of power in low gear. Transmission is consider smooth. Surprisingly even it is more powerful than Shell, the fuel consumption is higher.
Grading:6.5/10
5. Brand: Mobil Synergy 5000
Total cost: RM63.17 or 35.093 l
Distance:486 km
Fuel consumption:RM0.113/km or 15.879km/l
Remarks: Good pick up and transmission from low gear to high gear.The engine noise is the second best just behind Caltex Techron 95. The fuel consumption is surprisingly better than any of the fuel in the market. I can not complaint anymore of this.
Grading:9/10
Since I have change my set of tyres during the test, I retest Caltex Techron 95 to cancel the tyre effects. The prurpose is the feul consumption.
Retest of Clatex Techron 95 with new tyres give me 14.6km /l which is even less than the first test 14.9km/l. I would said the new tyres on the fuel consumption is negligible.
Ranking:
1. Mobil/Esso
2. Caltex
3. BHP
4. Petronas
5. Shell
Testing finished on 1st Nov 2009.

i curik ur research..
thanks..
I tested most of the fuels with ron95 vs ron97. Why? To test if it is really cheaper as it claims to be. I don't have the numbers right now but ron95 fuel consumption is higher as compared to ron97. So ron95 is really neither cheaper and there's also risk of engine damage.
sigh
I wish to see your RON 95 vs Ron 97 comparison data
ur reseacrh is really gud....i've also tried 3 fuels....caltex techron, shell fuelsave and mobil 5000....mobil do give da best miallage....and shell do give da worst millage....
thank you so much. i will change to ron 95 with caltex for this reason. thank you again
There is many more ways to determine the fuel consumption.
1. When did you pump in the petrol? Morning, Noon, Night?
2. How fast u press the nozle to fuel in? Fast or Slow?
3. Driving with AC or without AC?
4. What kind of engine oil did you use? Normal, semi syntethic, fully syntethic?
5.How often do you do your car services?
So seems there is many issue to be study, im sure you cannot measure the lvl of fuel consumption with your lousy calculation. Sorry to say this because your case study is just like an advertisment for a certain fuel company.

sorry, it's seem your data not good / fair enough..
could u tell / show us how do u calculate the figure?
Based on your data, petronas is the best.
I believe your comparison is quite good. Though many factors govern the results, your comparison is based on your own driving style which should be consistent based on your given conditions.
I wud say excellent effort ��
Another thing, comparing RON 95 and 97 is actually baseless. Obviously, both RONs have different calorific values due to higher octane in RON 97. Regardless of what RON, fuel consumption mainly depends on the health of your engine and driving style. FYI, using lower RON fuels DO NOT damage your engine. Most of car manufacturers design their engines for RON 95.
