i just use gas for mine, its a older car, n always ran on regular, so i dont wanna shock the system by puttin a higher octane gas into it. :p i work at a gas station so, its like a $1.17 a LITER here for regular

No, it just changed to that where I live. I guess higher crude prices mean higher refining costs for the different levels... it used to be only 20 cents more for premium, but now it's 30... its bull, but hey, what can you do? Can't exactly stop driving...

Man that seems kind of expensive... a liter is close to 1/4 gal, so you pay, what... $4.50 CND/gallon? Anyone know how CND compares to USD?

With gas at these prices, I would be using the lowest possible octane possible. If not you're just pissing money away. My gas costs $330 to $365 a month. I'm glad I don't have the GTP anymore.

yup 67L is 17Usgal

1.3Lit is 1gal

Yea premium is bad for GTs. Those deposits that can be left by using premium in a regular car can be very harmful and the potential for burning a hole through the piston becomes a possibility.

That's flat out crazy. I only live 7 miles from work so my gas is like $100 a month.

That is crazy... my gas budget doesn't exceed $100 a month... I'm exactly 7 miles from work too, so I fill up every two weeks, and it's usually right around $50 per fillup.

I'm not crazy about how much gas costs me per month with my 70 mile commute. But I manage to work in RI and make the same kind of money I would make if I were a developer in Boston. I had a boston job and it sucks.

I'm glad I don't have the GTP anymore.

Wow...

You are crazy.

Actually, as much as I loved my GTP, there wasn't a month that went by without it going into the shop.

I'm glad I don't have the GTP anymore. I couldn't afford the gas or repairs.

wow.. i live like 1 mile from work... but don't you guys go out? i fill up every week for about 50-60$. ouchy.

As far as octane goes if you use anything higher then whats recommended you are only wasting money.

If your car is recommended for 87 and it runs better on 91 then you have some issues inside your motor.

If your car calls for 87 use it.
If your car calls for 91 use it.

By law the 87 octane has to have the same detergents as the "premium" so your not really gaining anything.

4.50 CDN is like something like 4.15 US I think

I use regular like it says in the manual for an SE. I use shell gas which is suppose to clean the carbon deposits. Is that true about shell gas. I use premiem gas in my se couple times and I started to hear this knock on the left side and had to get that fix and man that was expensive so don't use premiem unless you have a GTP.

I spend about 150- 200 dollars and month. Gas prices here are 3.14 for regular and every fill is about little over 40 dollars plus I go to school and work which is 30 minutes from home.
