Premium Unleaded VS Regular Unleaded (Civic 2009)

[Derrick28]

Hi guys,

Just a quick Q's does anyone use Premium Unleaded for the Honda Civic 2009...reason i ask is does it worst it...since it's like 10c more expensive but it's more efficient for the engine right?

try and tank of both and you decide for yourself

i have only used premium in my fd, and wouldn't step below it.
but then again, i dont care about the petrol prices.. its a few cents here and there..
but in the long run, your car will run better and get you further.. and it makes my exhaust pop. lol

you should factor in the time/value for yourself driving to the petrol station sooner on the 91 octane petrol, rather then getting that extra 50-100 km's on the premium.. get me?

I only use prem. too.

It's recommended, so it's more than likely to have benefits outweighing cost

Premium Unleaded FTW

I have noticed when I use unleaded, the car is very jerky on/off the accelerator ( e.g 4th gear 60km/h)....much smoother using premium. I get the same mileage using 98 and E10, but much better mileage on 95 (not sure why)

[ekdez]

are you auto or manual?

i think your meant to get more mileage out of lower octanes, but it depends how you drive

[JOhnnyFD]

engine is designed to take in 91 unleaded and E10.. no point in putting 98, waste of money and i see no huge difference in milege
havent even tried using E10 as i heard bad stories abt it

but when i use 95, the car runs smoother than using 91

I drive manual....although I wish I had auto now....cannot ever get gear changes smooth...I drove Getz the other day and it was way easier to change gears.

Just need to get use to the clutch for smooth gear change . Try wearing a pair of shoes with a low sole (so you could feel the friction point a bit better), but yeah back to the fuel if you really wanna know how a tank of fuel is, you prob have to fill it up a few time with the same fuel and run your car almost out of fuel or else you will just get a mixed fuel and it will feel the same. Iam getting about about 570km with 44L of bp ultimate. on a my10 manual vti.

[curtis265]

You can't shift smoothly because of the DBW lag.

just hold ur clutch in for a bit longer to let the revs drop a bit more

Does anyone use the octane booster additive that you put after filling up?? Is it recommended and or does it work well?
Interested to hear experiences.

with my car i get 40 to 50k's more per tank so in a way i'm not paying any extra
