Does Fuel Octane grade affect your ride???

[SaNibOy]

I do feel with my butt dyno it does feels diff with diff RON although ppl says its not true and higher RON. It does feels sluggish with lower RON.

When my car was in stock condition, I did NOT feel any differences between 95 & 98 (or even VPower).

 

To me, outside air temperature makes a lot more difference in butt dyno than RON. The cooler, the better.

Many thanks, now I know why Champion Motors had been repeatedly unable to set the ignition timing properly for Suzuki 800. They used Japanese petrol specification workshop manual to do my car. Finally I DIY it right (so lucky)

that only goes to show u how 'good' e workers at e 'AGENTS' r.

 

Even their own cars ty also dont know how to set timing.

 

Can u imagine how ty do major repairs.

 

Now we know why so many cars in SG fall apart even b4 ty reach 10 years.

The various fuel grades available in SG are meant for the variety of cars we have on our roads. I don't see the point in using Shell V-Power 98 if you have a 1.6L car giving out 100bhp, unless it is your desire to further enrich the petrol companies. A car producing 100bhp ain't gonna produce any more power on higher octane fuel if its meant to run on minimum RON 92.

 

I often see Toyoya Vios owners pumping V-Power at the petrol stations. I don't know why. I rented a Vios during a recent holiday in Koh Samui and guess what, I was told by the rental company to pump RON 92 petrol and nothing more. The car drove like a Vios should be for its power and build.

 

The management systems in modern engines can prevent the engine from "pinking" when a lower grade of fuel is used as a temporary resort. If you have a car which needs to run on say RON 95, but for some reason you can only use RON 92, you can do so for a couple of tank full without causing any potential damage. But prolonged use would often wear down the engine faster, causing it to lose power and behave like a lesser powered car.

 

On the contrary, if you have a high-powered car, say a GT-R, Ferrari or the equivalent, then you should always use the best grade. Such engines in these cars won't take to low grade fuel happily. So visiting the V-Power pump is a must. Anyway, if you can afford a GT-R, Ferrari or the likes, V-Power ain't gonna cost you an arm or a leg right?

 

My experience so far in using various grades of fuel (and with that I mean only RON 95 and 98 cos my cars can't use grades lower than that) is that the higher grade octane fuel does make the engine run smoother when cruising. Its doesn't make my cars any faster during acceleration (that's a fact) but it does allow the engines to idle a bit more quietly when stationary.

 

So if you want more power, buy a car with a bigger engine. A Vios running on V-Power won't turn it into a Audi S5 or TTS...

What if the car manual recommends RON98 for "nominal performance" (which presumably means factory-rated power/torque), but states that RON95 can be used if it's all that's available, and if there's an absolute emergency, RONs down to 91 can be tolerated for short periods?

 

That's pretty much what my manual states, and I do care about performance, so I go with RON98 (never V-power, unless they have that promotion where they price 98 and V-power identically).

 

My engine is N/A but it does have a relatively high compression ratio (12:1), so there may be some justification to them recommending RON98.

Mine PI.

tried 90- bit slugglish

95 & 98 cant tell the difference.

Put in additive, -- kenah drugs, or steroid.

 

Anyway, I just pump 98 usually.

[Darthrevan]

no difference
