The difference of fuel consumption on Urban driving condition is insignificant in my case. I have not had the chance to try RON95 on highway yet. But it would be interesting to see if it differs. With RM0.25/L fuel price difference between RON95 and RON97, we are talking about RM16.50 difference(assume 66L fill up) per full tank. Also, that would be RM60.245 difference per monthly fuel expenditure at the same amount of fuel used for last month. Naah, I can live with that. But it will remain to be seen if there is any significant difference when it comes to highway mileage. I will try it when I have chance to go long distance travel down to Singapore again. At the moment at urban driving, I think I will stick to RON97. Not much difference lah. Somemore car feels more lively when RON97 is used hehe<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite8" alt=":D" title="Big Grin :D" loading="lazy" data-shortname=":D" /></p></blockquote><p></p>
[QUOTE="turbosnail, post: 379371, member: 8183"] Latest update: Filled her up with RON97 at the same Petronas station: Amount of RON95 consumed: 44.391L Mileage traveled: 409.2km Driving condition: Urban Fuel consumption: 10.85L/100km Total RON95 consumed: 240.98L Total Mileage: 2145.6km Final fuel consumption: 11.23L/100km Urban fuel consumption when RON97 was used before RON95 fill up: 11.56L/100km Observation: When switch back to RON97 I could feel a noticeable difference. The engine becomes more responsive. When floored the pedal on Pg Brdge I could the car was more eager to go faster than when RON95 was used. Fuel consumption: It seems to me the fuel consumption is better when RON95 with newer Petronas additive is used(~3% improvement). Conclusion: I don't know if this is only the case for my car, or it is for all E34 with the same engine model and capacity as mine.
