I totally disagree. I would never, ever put regular (87) in my G. Premium only (93-94)

 

When I was younger and worked at a gas station, they used to tell us that the higher grades accually give you better fuel economy then the lower grades...essentialy eneving out at the end. BTW your driving a G, a performance car -- remeber? Don't you want the best and the most out of your ride, not to mention its only a $2 difference at the most.

 

My precious G deserves the best... though the "experts" say other wise and pretty much say there is no need to put higher octane gas in....

I disagree, no matter what they say that the difference is not noticable... all of us in this forum who loves the G will notice every little thing about our cars no matter how small. The mere thought of putting "cheaper" gas in ma G is not an option for me.

 

Ill drink to that!

 

I'm pretty sure it doesn't say that....

 

If you put 93 into a hyundai elantra youre going to get worse mileage because the fuel will be unable to ignite... Just because whoever told you that worked for a gas station, doesn't mean they know how cars work

 

well, I thought about it more and with the mileage I put on my car, it comes out to less than $100 a year. I would probalby spend $100 for a mod that gave me a 5% horsepower gain, so I may as well spend the money for the higher octane. Oh and ipse_dixit, I'm not on the Roadfly boards, must be someone else with a similar handle.

 

Another point is that the differance in price between 87 and 93 octaine is getting to be smaller and smaller and especially on a % basis, at least in my area. I got fuel yesterday and 87 was selling for $2.87 and 93 was selling for $3.01 or only $0.14 a gallon differance. Maybe since almost everyone is buying 87 nowadays to save some money, the demand is driving up the price of 87. BTW since I got 11 gallons on the fillup, I could have saved myself a wopping $1.54. Since I'm getting 24 mpg and drive approximately 8000 miles a year, I'll use 8000/24 or 333 gallons a year. If the differance in price between 87 and 93 remains about the same, I'd save around $50 a year in fuel costs. This of course is assuming that my gas mileage will stay the same if I use 87, and I would be suprised if that were the case.

 

Yeah, and just because some guy is on an internet car forum, doesnt mean they know how cars work either....

A car made for 87 will NOT get worse mileage on 93.

 

As a 15 year old with my first car I learned that premium gas was better than regular. The car had a little more power, had less crap in the fuel lines, started better, etc. Little things a lot of people don't care about. I haven't used anything else since. No way I would not use it in a car where the manufacturer says to use it. Doesn't make even the tiniest bit of sense.

 

The owners manual states that the sedans with automatic can use 87, but coupes and 6MT sedans to use 91. Why can't the coupe with automatic use 87? Same engine, same specs.

 

Hello everyone. I've been reading the posts and decided to search the net for some articles pertaining to this topic. Here's an interesting article I thought you might find informative. It talks about the various grades of fuel as well as racing fuel and I think that it gives a great explanation of how it all works.

Okay... I guess you are the expert. And i'm sure you know exactly how the fuel/spark/pistons interact, hence your supported statement..

 

I experienced the exact opposite after Katrina.

Usually the difference between 87 and 93 is approximately 20 cents. If I fill up on days when some stations have a 5 cents off for premium the difference is 15 cents.

Right after Katrina the difference between 87 and 93 soared at some places to as much as 45 cents.

So I started mixing 87 and 93 to approximate 91.

Surprisingly, I got better mileage. I thought it was a fluke so I did it again. Still better millage. No noticeable loss in power.

I'm continuing to do it.

As for all the posts that it's just a dollar here, two or three dollars there. I'm able to own the coupe and so much more because I never **** on a dollar here or there.

 

That's a very good point.......that the higher octane fuels have very good cleaning detergents in them to keep the combustion chambers, exhaust ducting, and catalitic converters cleaner than the cheaper, lower octane fuels.
