use 98, better drive feel and maybe the dynamometer says no effect and legislation in eu says cars must run on 91 ron... but my personal experience tells me that 98 ron in the car is worth the difference..

Used to get by on 95RON. One month felt more loaded so tried 98RON for a few tankfuls to see how. Somehow engine feels smoother and GB less urgent to upshift (i.e. less engine labouring) and seems to be in correct gear more often.

i've been on ron95 since day 1... :thumb:

For my previous E250 CGI - same 1.8L engine but stock tuned 204 hp runs good FC on 98 than 95 or V-Power. This was my findings after many rounds of 95 - 98 & V-Power over nearly 18K km.

Currently also appears to be the same for good FC on my ML300 3.0L NA engine with 98 than 95 or V-Power over 6k km.

My previous W203 C180ML works well with a mixture of 95 & V-Power

2 tank 95 than V-Power :becky:

98 for more power... but it depends on ur wallet as well... Vpower drains too fast.
