Im in the process of saving up for a car and was wondering if the cost of premium gas breaks your wallet. Being in CA I would think it does. What octane does the tsx require? Thanks.

It doesn't. You need 91. You can always go with 87, but the fuel consumption increase will offset the price differential between 87 and 91 octane.

TSX requires a 91.
Coming from a Accord V6, TSX gives me a way better gas millage. Well depend on how you use the car. I don't high rev my TSX so I get about 29 - 32 mpg compare to 22-26 on my 98 accord V6.

I used 89 on my V6 and 91 on the TSX. At the end, TSX still comes out a winner.
I saved about $50 - $70 per month. But I also drives about 3500 miles per month. So i can really see the difference. $330 (V6) to $260 (TSX)

Hope it helps

thanks for the replies. I was getting intimidated by the thought of filling up with premium, but I dont think its a reason not to buy the car.

Man.... Don't give up the TSX because it requires 91...it's really not THAT much of a price difference....to me, when you can afford the TSX, I am pretty sure you can afford to fill it up w/ 91....and DON'T use 87 in it, as it will hurt the engine!!

That wont stop me from getting the car, just something to take into consideration.

Seriously, considering the difference is only about $3.40 for a full tank, why skimp that little bit? Just spend the extra few dollars and get the proper gas.

Here's the math I did: I drive ~20k miles a year. I get ~25 mpg (mostly city, and 5AT). That's 800 gallons of gas a year. I figure a $.20 increase for premium, which comes to.....$160/year. Or $13/mo. Or about 1 pizza a month. If you can dodge a wrench....uh, i mean, if you can afford a $27-30k car, you can afford $160 a year extra for gas.

I use 93 octane fuel in my TSX... And I always make sure that the fuel comes from a station that sells on government rated "top tier gasoline" I know that quick trip gasoline as well as texaco and shell clean system 3 gasoline is all "top tier".....
The top tier stuff at 93 octane costs zero more than 91 octane fuel

dzuy

no. it's only ~20 cents more per gallan

i usually fill every 320-330 miles and it's usually ~12 gallons.

so .2 * 12 = $2.40 more than regular gas. so it's not really a big deal.

so i fill every 3-4 days, let's say twice a week

so 1wk * 2.40 * 2x a week = $4.80/wk

52 wk * 4.80/wk = ~ 250/year more than regular.

big whoop. you could skip a mcdonals dinner a week and make up for it

Ummm didn't you say that already.......2 posts up?

Despite what everyone says, I definitely see a difference. I fill up more than before, it seems. And I get about 5 mpg less than my Celica. I averaged (city and highway) about 28-31 in my Celica. I get maybe 22-26 with the TSX. And I am paying for 91 instead of 89. And it's a larger tank which doesn't mean anything since it goes the same distance and costs more money to fill up!

Sigh. This has been beat to death soooooo many times. Lower octane does not hurt the engine! Right from the Acura website, quote:

** Gasoline with an octane number lower than 91 may be used, with reduced performance.

This is straight from the TSX specifications page.

It *may* hurt your zero to 60 time, or your top speed, but it won't hurt the engine. BTW, If you live at high altitudes, lower octane is advisable.

dom

Thats apples to oranges and I can see how it makes a difference. But like dzuy posted. Using prem over reg in the same car comes at a ~$250 yearly premium.

J-Mack

This may be a little extreme but does anyone mix different octane gas. $2-3 a tank is less then I expected. Sounds like its not something to take into consideration after all.

foolioness

I've never mix the octane.... 91 only. Remember your MPG on this car depends on your driving behavior. If you like to floor the gas, the don't expect to get a good millage. My

Discover has a gasoline cash back plus card that gives you a discount of 5% on all gas purchases. This offsets the premium price almost completely. And it's 5% all the time, not just the first 6 months. I've built up a huge cash back bonus just on gasoline....look into it.

oh man...using premium gas...esp within the first month of getting my intake installed = F*ING HORRIBLE. I swear i was at the gas station every 2 days. but now that my ecu has adapted to it everythings goin back to normal
