Due to the cost of fuel these days i have been putting regular unleaded fuel in my A-spec..i usually opt for the higher octane supreme but at $1.03 a litre it can get very expensive....ever since the switch i have noticed the slight hesitation with accleration the "knock" just woundering if anyone else has done this...i know premium fuel is better..but will me using the regular lower octane fuel hurt my baby in the long run....??????

According to the owners manual "long term use of regular grade gasoline can lead to engine damage". My advice to you is if your leasing or plan to keep the car only a few years then continue doing what your doing. But if you plan on keeping your car for a long time either put the proper octane or dont drive it until you have enough cash to pay for premium fuel.

knocking = bad; pure and simple, and can lead to damage. If your engine is knocking, go up in grades until its gone.

Agreed. you arent saving any money using regular. odds are your mileage is going down so teh amount you save in the price difference your burning up in less mileage.
do the car a favor and put back in premium (minimum 91) especially since you have the A-spec

LOL hes got the aspec and puttin 89 in

PenancE

if u can afford it, put the gas in....perform=greater

dark inspire

better than putting 87

samkws

he says regular unleaded, which means he's putting 87...

maybe you should think of trading in a civic DX, which runs 87 gas and almost 40mpg on hwy

I used to use the 91 grade then went to the Sunoco 94 now thats all my car will run on I wouldn't even think of going under 91 . I think the fuel door says to use premium unleaded only and I don't think its really to help the gas companies profits, its so the car will run at optimum performance levels

All I can say is "DUH !!!"

medicshane

DUH yourself drcookie ....it was just a question...looking for other peoples opinion not sarcasm!!

i dont think that 94 octane fuel is good for our tls? i remember seein someone talkin bout it be4 in another thread..

fsttyms1

it wont hurt it, but it wont help it since the car has been tuned to optimize 91 or greater. we dont have 91, we have 87,89 and 93
