1. Regular Vs Hi-octane

Guys quick question:

Currently i am using Regular category fuel in my Car (Civic 2013) on which i am getting an average of 8 to 8.5 Km/L.

I have conducted a small study and want to share my assumptions and want to get your feedback on it.

Scenario 1 - Regular fuel amount = 5000 rs. / Price = 94.5 rs = 53L - - -Average 8KM/L = Total 425KMs

Scenario 2 - Hi-octane fuel amount = 5000 rs. / Price = 114.5 rs = 44L - - -Average *9KM/L = Total 396KMs

Difference = 425 - 396 = 29Kms

so i am just curious that just for the sake of 29 - 30 kms why are we all not using hi-octane in our cars. confused ? ? ? ?

hi octane is not for all engine hi oct burns slow than normal petrol and if the compression ration of engine is less than 10:1 than it will deposit carbon of vavle which is not good for engine life

3. Running Car on 100% Hi-Octane may not be very ideal.
Make 50/50 blend and am sure fuel average will be same as you will get for fully running on hi-octane and engine will be happy too.

Sorry what does 10:1 ratio means? Does it mean high octane is not good for weak cars engine?

5. boss what about Civic R18 it has 10:1 compression.

6. sorry it has 10.6 : 1

7. still waiting for xperts feedback

8. guys i always fill with supreme coz mind says petrol pump guys fill supreme in the name of hi octane ... is it correct ?

9. go to company operated pumps and you are good to go. . .

Yes i also want to know that

11. I saw mileage on the new city and premio jump up on Hi-Octane.

Average on my Civic with 50/50 ratio remained almost the same. So yes it depends...

as your dp have swift picture I think u own swift if yes then don't fill hi octane in your car it will harm your engine

13. the best way to find out that does your engine suit hi-octane or not is to fill a very lil quantity of hi octane with 40/60 ratio of petrol and see if you car perfromance increased it if it increases a lil then u can use hi octane in your car

14. I filled super regular 100% on my civic reborn m/t with a/c all the tim.....it give around 9.5-10km/L as I drive within city mostly.....hi-octane 100% I filled on my markx as it got compression of 12.0:1.....as u see mostly jdm cars sometime need hi-octane as its previously was running in Japan as Japan fuel is much better than Hi-octane...u can try 60/40 or 50/50 on ur civic if the mileage doesn't improve use super regular 100%

15. Almost In All Modern Design Engines....They Now Have Higher CR And Since Our Premium Is Quiet LOw On RON's So Its Always Advisable To Use 60/40 On These Motor In Order To Avoid Detonation And Knocking.........!!

16. civic 2009 manual

i have been using high octane(no mixing of super) from last couple of days....performance is definately increased and about average...

i filled 1500 rupee worth of high octane that is equals to 12.93 litres as per todays rate and it went for almost 125kms(ok there was the redlining alot) which gives out the average of 9 something kmpl which would have been around 12 if i wasnt too heavy on pedal coz out of these 125kms,50 were pedal to the metal...if i take the average to be on 11.5 kmpl...

while on super it gives almost 10...tank is of 52L hence it will go 520kms in 4888 rupee of petrol
and on high octane it will go 600 kms in 6000 rupee of petrol so i will be getting 80 more kms in 1000 rupee more of petrol...take loss of almost 200 per 600kms which i dont think is a loss coz these 200 can give your cars engine a new life

17. and this super we get here messes alot with the fuel filter thats why i shifted from super to high octane

Are you kidding? High octane is the only recommend fuel for automatic swift and in manual swift high octane or regular can be used.

Btw the way to know whether your car requires high octane or not is to know what octane no petrol is required for it also known as RON. Regular petrol is around 87 RON and almost all new engines require 91RON. The boost one gets with high octane is because you give the car right fuel and so it performs to its full potential. Its not really fuel giving boost but rather its the engine perfoming optimally.
