Does Fuel Octane grade affect your ride???

[Zangetsu77]

Out of curiosity, whats the difference between v power & 98?

 

V-power is branded 98 which cost a lot more, and comes with complimentary wind screen wipe and tyre shine.

 

I guess it could be possible that the GR guys meant, "Only V-power pls !! (cos we bloody put the GR car decal, sticker and HKS tag!!)"

 

Hurhur... Ever since like 10+ years ago when Shell did the series of V-power ads, i have been pumping V-power hurhurhur... Just a sucker for commercials...

If ur car is NA and not high powered just use the minimum ron rating... Everything is psychological. Just look for the petrol brand that will give u the best mileage... Due to different additives.

============

 

My normal Optra needs 95. So did my COE Corona.

 

I do feel engine smoother when I use 97 though.

 

I wil only pump 92 when I just fill <20 lit to top-up & bring my fuel gauge to 3/4 b4 I go JB to fill to the top.

 

Otherwise I wont use 92 cos my car min required is 95 to run properly.

if you understand how car ecu work then you would know which octane is best suit for your car. In brief, as long as the ecu did not detect any knocks, it will continue to use the most optimium fuel map to run your car,octane 92, 95 or 98 does not matter. If in the event of knocks detected, it will switch to alternative but lower octane fuel map to protect the engine, which typically result in poorer mileage and perfomance. Therefore, a fuel with higher octane level is more stable and hence can resist knocks better than a lower octane fuel. Just follow what the manual recommends and no harm done to the engine...hey, my evo if in stock setup can use octane 95, so say a sticker inside the fuel lid.

Funny my fren say his evo needs 98.

I use V-Power for both my Toyota Camry and Alphard.. Its the best thing.. I have tried using 98 but in Malaysia N-S Highway , I can feel the difference

Just monitoring Myvi now, and it seems to be below 12km/l with Octane 92 (recommended minimum Octane 90), t=so a colleague laughed at me. Better than 12km/l with Octane 95, and 1bove 14km/l with 98. Intend to monitor with Octane 100 next

Can hear my engine "rattling" when car is climbing slope, when 92 is used.

No such problem with 95 and above.

My ride 05 civic based on SG fuel

 

RON 92 - When RPM go above 3K the engine vibrating violently and will lag before picking up speed

 

RON 95 - When RPM go above 3.5K the engine vibrating abit but will not lag when picking up speed.

 

RON 98

[Troyempire]

Bro, unless your car is type r or tuned, at least 95 should work fine. Better have a workshop to check your car engine.

 

Will send it for checking soon.

[Kiadaw]

Most car should run fine with 95. After all, thats the most commonly available grade

 

We are lucky (or not lucky) in Singapore where all petrol station are branded & almost all have 98. In other countries like UK, most petrol stations have only unleaded & diesel. Branded petrol like BP & shell are few & far between, & usually on motorways (expressway in UK).

 

Some people tuned their 98 octane car to 95 octane for convince seek, same in US. That is also one of the complain from Clarkson about the evo, that it only take premiem petrol.

 

If your normal family sedan need 98, then suck thumb liao. But shouldn't be lah. best to check engine lah.

for me the main issue is the mileage. performance really marginal. my preference for mileage stand point.

shell v power 2% more than usual but pay 5% more!

shell 95

shell 98

caltex 98

caltex 95

Mobil very seldom use so no ,comments.

petronas 95

spc really to me worst on all aspects

 

I tell usually same petrol for few weeks. I realize the car CPU will retune when switching Ron type car do experience some unstable idel. then next full tank ok.

 

so I recommend shell 95. bang for buck. if got many mule. then v power.

What car u drive? Is it Evo9 also?

 

But my Optra needs minimum 95 but I get better mileage with 97.

============

 

If yours had the ignition timing advanced more than manufacturers specs, u wil need higher RON otherwise u wil get knocking but advantage is slightly more power.

[Pisces69]

My Princess Sunny only drinks Caltex Ron 98, 95 gives her tankache and cannot run. Dunno why??

============

 

Maybe yr ignitiom advanced for more power? But ECU wil retard it automatically if u use lower RON but less power only.

 

Modern cars ECU can do that. Older cars with manual timing cannot adjust automatically.

In SG I wil fill the cheapest 92 but in MY I fill 97 so the average RON in my tank usually is 95 at least.

 

But when I only fill 97 for several tanks, the engine smoother & FC also better.

===========

 

Oh if your recommended is 90 then can pump anything.

 

But if yours is PI car, remember that Japan RON & SG RON is different.

 

They use different grading so your 90 might mean 95 in SG.

What car you are driving.

 

My friend got swift sport that is suppose to be high compression engine, but still he pump 95. He just say just don't go above 6k.

 

Work place only 5km some more & red plate but still so very conscious about fuel cost.

 

If only my workplace is this close. Mine is 22 km & got ERP gantries some more. Sigh

 

22 km is still reasonable. For mine, one way is almost 38 km.
