Vantivetech 2nd Gear May 7, 2015 Share May 7, 2015 My personal choice is also to use ron98 not so much for improved mileage but for the drivability. Maybe I am also more sensitive, but with ron95, with load (upslope or etc) at light throttle, I can pick up some pinging. Cars are supposed to enhance lifestyle so use the fuel grade that allows you to further appreciate this cash sucking machine :) ↡ Advertisement Link to post Share on other sites More sharing options...
Ken138 4th Gear May 7, 2015 Share May 7, 2015 Actually its not the Ron but mon. Go according to manufacture guide is still 95ron gasoline.. Other specs impact on rhe milage like density etc.. In general, 98 ron is indeed denser thus high milage.. ;-) Link to post Share on other sites More sharing options...

Andyngps 5th Gear May 7, 2015 Share May 7, 2015 (edited) Hi there I am Francis Goh. I bought my Maroon X model on 23/03/2015 from Swee Seng Motors. I just went for 1000K servicing. The workshop recommended use of RON 98 petrol in stead of RON 95. THey said can improve mileage by about 60KM, and calculated to be about the same costs, & saves some of the engine parts from damages. Any advice? True to some sense. I never tried 98 but I tried vpower. Can feel quite a difference. Somehow you do not have to step on your throttle as hard and yet responsive. I am still sticking to 95, ever since the higher tax required for above ron95. To add on, somehow it didnt make any diff for my previous cars.

Ken138 4th Gear May 8, 2015 Share May 8, 2015 Lab tests of 92/95/98 etc by sgs/Its shows higher ron gasoline are indeed denser. Thus slightly higher calorific value n milage.. There are other specs beside ron that influence quality of gasoline n driveability like olefins etc.. Thus choice of brand might be important in some countries.. Some gasoline are not directly from refineries but blended from components like napatha etc.. Some must be spike with additives like ron enhancing ones like mmt which is unstable.. Do exercise care when one pump whilst going up north.. :-) Link to post Share on other sites More sharing options...

Even my good old FD1 gets noticeable better mileage and quieter engine and slightly better power with Caltex 98 vs Caltex 95. And Caltex Techron is considered the 'ideal' gasoline brand for Honda engines in SG. Yes FD1 can run on 91 octane onwards, but you really lose a lot of power and poor fuel economy if u use 92 octane in SG. I'd like to think its the additives (or the lack of it for lower end options) these petroleum companies adds to their fuel stocks that made all the difference. Octane alone shouldn't be the sole factor. Link to post Share on other sites More sharing options...
Vantivetech 2nd Gear May 8, 2015 Share May 8, 2015 All that are highlighted by brudders/sisters are correct, additives, Ron, etc chemicals..... However to many drivers and not so technically inclined, it becomes a strain for them to decipher what are these additives/chemicals. These may not be readily published or made available to the end user, thus generalizing experience with fuel brand and Ron maybe most appropriate for most. For the techie, keep this going :) Link to post Share on other sites More sharing options...
Wattokkingu 3rd Gear May 8, 2015 Share May 8, 2015 Chipping in my 2 cents ;) For my previous ride (Honda), i cannot honestly feel a difference b/w RON95 and RON98. For my current ride, can't feel a difference b/w RON98 and VPower (from JB). For both of these cars, what makes a noticeable difference is the engine oil used. The decision to use a particular brand of fuel (SPC) is based on practical reasons like credit card discounts, distance of petrol kiosk to my home.

Waterh2o 4th Gear May 8, 2015 Share May 8, 2015 Report in BT today A small, cool SUV from Honda has powered past the traditional Toyota model to claim the mantle as Singapore's most popular parallel import (PI) model as the total PI market boomed on an expanding COE quota. In the first three months of 2015, 380 units of the Honda Vezel were registered collectively by parallel importers across Singapore (see table). The Vezel is a Japanese domestic model, the first of which was registered here last June. On the other hand, the car sold by authorised Honda importer Kah Motor is the HR-V, of which none was registered in the first quarter of 2015 as it was launched here only in mid-April. In recent years, Toyota models have occupied the top three spots, usually with the Estima, Alphard or Vellfire, and Harrier in that order. But the attractive styling and price of the cheaper Vezel has been popular with replacement buyers returning to the market over the last half year. The Toyota Harrier is now the runner-up with 338 units registered, after having ended 2014 in third place. The Vellfire is third among the Toyota models with 48 units, while none of its mechanically identical twin, the plain-looking Alphard, were registered by parallel importers in the first quarter. This is because the new-generation Alphard and Vellfire are already here and undergoing homologation. The first units are expected to be registered only later this month. Overall though, the Toyota brand is still the top PI brand, with 580 cars registered (see table). Honda is the second most popular brand with 432 units. Last year’s No 3 has swopped places with Mercedes-Benz, which has garnered 103 grey imports. A total of 1,169 PI cars were registered from January to March 2015, or an eye-popping 189 per cent increase from the same period a year ago. Only 404 parallel imported cars were registered in the first three months of 2014, in a reflection of the tighter COE supply this time last year. The increasing number of COEs being released resulted in a total of 10,364 new cars registered across the industry in the first three months of the year, or up 73.8 per cent increase from the corresponding period a year ago. This means that the year-to-date share of the PI market is 11.3 per cent, or a big jump from the 6.7 per cent in the whole of 2014. Toyota is still the top PI brand, with 580 cars registered A wake up call for Kah and all ADs. Wake up your freaking idea. Link to post Share on other sites More sharing options...
Alheych 6th Gear May 8, 2015 Share May 8, 2015 A wake up call for Kah and all ADs. Wake up your freaking idea. Actually cannot totally blame them. Honda HQ would never have allowed an authorised dealer to take stock from Japan, or else their production capacity in South East Asia would be totally wasted. And If all that Thailand produces is the low spec and older tech HR-V, what can Kah Motors do? The same applies to Borneo as well. When PIs were selling the Wish with Valvematic engines, Borneo was still selling Dual VVT-i. Being an AD is sometimes like a pawn, being moved around by HQ to fight a losing battle.

Ken138 4th Gear May 8, 2015 Share May 8, 2015 In traditional gasoline directly from refineries, quality is much better. Higher octane mostly use feedstock ie reformate from RCC unit thus the better quality in terms of ron/mon etc. this blend stock is much stable n giving more caloric value n milage. But some gasoline up north is blended by traders using various components therebu cheaper cost n maximising profits. Needless to say, certain specs are blended to hit the limits.. Over long term, the engine will suffer.. So do take care n avoid certain brands up north... :-) Link to post Share on other sites More sharing options...

Go_francis Clutched May 9, 2015 Share May 9, 2015 According to the guy at the workshop, some engine parts will not last after 4th year, if we keep using RON 95 or below. Also, the could be improved mileage if we use RON 98.I have just pumped RON98 (I last pumped RON95)... It costs me about $0.20 more per litre.WHen I used RON95, it clocked 440KM (38L +)...I always pump when there was still 1 bar on the petrol indicator.Filling up a full tank from there would be 38Litres + I will monitor the fuel comsumption.
