ausdev Posted March 21, 2018 Share Posted March 21, 2018 Hi guys, Just wondering what 98RON fuel you recommend? I have a 2009 IS250 which I just purchased second hand. I know the owner and it was driven pretty lightly over its life. Want to run 98RON fuel for a bit to try and clean out any gunk. Is their any difference between Shell VPower, BP Ultimate etc. Is one better than the other? Just wondering your thoughts? Quote Link to comment Share on other sites More sharing options...
Atlantis Posted March 22, 2018 Share Posted March 22, 2018 I get most km out of a tank in this order: Mobil Supreme 98 BP Ultimate Shell V-Power I don't use Caltex... issues in the past have tainted my view of their fuel. V-Power seems to go "off" in around 2 weeks and the car can feel sluggish and ping. Haven't experienced this with Mobil or BP though.

AlexFS250 Posted March 22, 2018 Share Posted March 22, 2018 Check this report out. I used to run only 98. Now just premium as per the recommendations on the fuel cover https://autoexpert.com.au/posts/do-i-really-need-to-use-premium-unleaded-in-my-car Quote Link to comment Share on other sites More sharing options...

Grungle Posted March 22, 2018 Share Posted March 22, 2018 Since I got my IS350 a few months ago I've been doing the numbers on 95/98 RON fuel, to see how much difference it makes. Different suppliers, but usually BP, as they're convenient to my route. I've probably put 8 tanks through it so far while I've been tracking it, and in $/km it's within 1%. I haven't had to drive in heavy traffic in the last week which means I got really good economy, so that has swung the calculation in favor of 98 by 0.8%. Before that tank it was better on 95, by 0.7%. Bear in mind I'm just recording the average economy displayed on the dashboard at the end of each tank - I'm not recording km traveled or anything. Interestingly, I get an 8% variance in the fuel economy just as a result of how or where I'm driving, and 10.5% variance in the fuel price. So, as long as you're using a 'premium' fuel, the way you drive and the cost of the fuel seems to have more of an impact (10 times!) than the actual fuel you're using.

Glorified Dus Briver Posted March 23, 2018 Share Posted March 23, 2018 I used to fill up with Shell V-Power for a few months until I decided to try BP Ultimate 98. I personally prefer BP Ultimate 98 as I experienced some sluggishness with V-Power overtime. My experiences with V-Power are similar to what Atlantis mentioned. I also noticed that the 98 prices for BP are far better than Shell V-Power (probably because Shell V-Power accept the fuel dockets from Coles).
