Can I use Ron97 on M54 car?

As per topic, seek advice from those who use Ron97.

I don't see why not...I would always find opportunity (and extra money) to fill in Ron97 whenever possible on any of my cars

No problem with the car. Only problem these days is finding a station with ron97 in stock.

Bro, glad you asked. The M54 thrives on the extra octane. I decided to try a tank of it since the price difference is so small. In town driving didn't feel any different but when I went out of town over the weekend, the engine was extra revvy. Extra sweet when being pushed. One of those things you gotta try to know. Seems to be more fuel efficient as well. By the time I get to Ipoh, odometer showed I've done 150 miles. Fuel gauge at 75% level. Not bad right? I was accelerating regularly to about 110 mph.

Very useful information Herbert. Thanks for sharing and increasing awareness on how RON works.


Pasting the content here for ease of reference:

"PETALING JAYA, Dec 2 — With RON97 now only 20 sen more expensive than RON95, more Malaysians are now able to purchase it. In 2012, both fuels used to have a price difference of RM1 per litre.

But what exactly is the difference between RON 95 and RON97 besides the price?

RON stands for Research Octane Number, a form of fuel quality and performance rating.
The rating system was developed by Russell Marker at American firm Ethyl Corporation in 1926, following Marker’s discovery that branching in hydrocarbons reduced “knocking”, or pre-ignition.

Following his discovery, oil refining companies rushed to increase the hydrocarbon branch chains to improve fuel quality. A higher rating indicates the fuel can withstand higher levels of compression before detonating. Higher compression levels may mean more power output. Filling a vehicle with a lower octane rating than the one specified by the car manufacturer may lead to pre-ignition, a scenario that would ruin the car engine in the long-run or even result in an explosion. Generally, higher octane fuels are used for vehicles with higher compression rations. A higher compression ratio gives an engine a higher horsepower per engine weight than one with a lower compression ratio — making the engine “high performance”.

RON97 is recommended for drivers of vehicles with an engine capacity above 2,500cc.
Octane ratings offered to consumers vary from region to region. Up until a few years ago, Australians were able to fill up with RON100 in major cities but can only choose from RON91, RON95 and RON98 fuels now.
In the United Kingdom, BP introduced BP Ultimate Unleaded 102, a petrol with an octane rating of 102 but stopped selling it in 2010."

mine gain no significant improvement by using RON97
the best FC using RON97 is 8.04L/100km (www.fuelly.com - not using on board computer reading)
and the best for RON95 is 8.09L/100km

btw, M54 can use as low as RON91...

AKI - anti knock index.....go google that feller...

my car engine N52 also min ron91........ so i just fill in ron95.....
still in the manufactur recomended Spec....

OMG!!

the person who wrote in the star... "RON97 is recommended for drivers of vehicles with an engine capacity above 2,500cc.".... buat malu malaysia.. macam tak sekolah..!


RON rating has nothing to do with Displacement,, but have everything to do with with compression. if you are not driving anything higher than 10.7 ratio... not even worth going there..

at AKI 89, every modern post 1978 engines with run that without any concern.


that's the problem when a journalist or writer trying to be Engineer....

so meaning m54b30 engine compression ratio of 10.2:1 should not be using RON 97. Whereas m54b2.2 (ratio 10.8:1) should use RON 97.

Sure can use.. just not worth the money for the minute different.. unless u redline every gear change..

for my Bike, 12.4 ratio of 12000 rpm.. cruising at 6000 rpm.. absolutely
