Everyone talks about not taking the 'risk' or not wanting to 'foul up the engine'. So what is this 'risk'? What happens?

And for all you Owner's Manual Holy Roller Fundementalists, the very same manual also says things like not riding with your hand out the window. I'm sure you'd never do that either. The manual also says you should ideally shift from 1st to 2nd at 8 mph. How often does that happen?

As for waiting to the last minute to fill up, well, if you have long commutes it gets down to 'E' pretty quick. But, it is better for your engine if you fill up frequently rather than letting it get down to the last drop. That last pint of gas in the gas tank is like the last cup of milk in the jug.

Anyway, I was just checking. Doesn't seem like anyone here has the nads to run regular, and just being another sheep in the flock I guess I won't either. Unfortunately my wife is the one who fuels up the G35X and she does not believe in premium gas. She thinks it all comes out of the same big tank. We'll have to see how long the engine in the X lasts.

I'd still like to hear what the actual risks are. Probably a lot less than we think. Again, if it aint knocking then what could be damaged?

 

In theory all gas rated the same octane should behave the same in a vehicle but in reality it doesn't. I have a subaru outback that takes regular gas... it does just fine on shell and a couple of others but hates exxon and cheap gas... it will have noticable issues with it, especially after I first fill up. This has been the case with that car for a few years now and occasionally I'll test another gas station and some she likes, some she dont.

And I'm positive my G runs better after a good wash, wax, detail. I just did it last weekend and wow! Must be the better drag coefficient!

 

just run meth and cheap gas. problem solved.

 

agreed on Shell. My G has used nothing but 93 octane Shell V-power for the past 3 years. Car runs great. Plus I have the Shell Mastercard so I get back 5%.

 

+1 on the Chevron premium. There is a Shell right by my house but I don't fill up until I get to a Chevron. My G love Chevron prem and I'll agree that the car feels better on Chevron gas. I thought it was just me but its cool you pointed that out

 

It's about $3.50 a gal for 93 here in ATL. I fill up for just over $50.

You should have thought about the cost of feeding a G before you bought one. If you can't afford the gas, sell the G to someone who can, and go buy yourself a sexy Geo Metro.

 

Cheveron Premium only for the G!

even my daily gets pretty good fuel too, 00' Neon 89 octane, sometimes if my pockets are full, I'll pump some 91 hahaha..

 

Nothing but premium in my G, and that's commuting 110 miles/day round trip.

 

I have done some test between shell and chevron with my turbo eclipse, and i can def say that chevron performed much better, i could boost 25-26 psi with chevron with out seeing knock. but with shell 22-23, any more and i would get knock. i also tune my car myself.

and i just filled up the other day $3.85 for 91, and i saw gas prices last night and they were $3.97!

 

yeah nobody is too happy about the rise in fuel costs...but its still not going to stop me from spending $4 more per fillup for premium gas.

 

Chevron or Shell premium only

but with these gas prices to come im glad a live a block away from school so i can walk

 

Im in IL and its near $4/gal. But for me its premium or walk

 

If worse comes to worse I''l have to swap a 4 banger or hybrid into the G....


....or use the thousands of dollars I spend for the swap on Chevron Premium instead

 

how broke can u be that u cant afford premium gas for ur car? maybe u shouldve bought a regular car so u can put regular gas if gas prices affects u that much. i always tell myself when i try to cheap out on things is "i can afford $5 beer and $10 shots when i go out but i dont wanna waste $1.50 to get myself a soda with my meal" lol that usually puts things in perspective for me

i think im one of the few that dont really care wat gas prices are cus in the end im gonna need to refill anyway so no sense in stressing about it. jus take it for wat it is and enjoy my beautiful g35

 

Trust me, I'm far from broke. Seriously. But that's not the point. The point is, most of you guys have finite resources. That means if you're spending more on gas then you get to spend less on something else. Like Jack Daniels, hookers, crack,video games, fuzzy dice or cold air intakes. Period.

So what can you do about it? Well, not much in regard to price/barrel of oil. The only two things you can do to save money are buy gas at the lowest price you can find it. This increases competition and decreases the number of gallons that the higher price stores can sell. OR, you can buy a lower grade of gas.

I'm just asking how many folks are willing to buy lower grade gas to save some money. So far, no one. And that might be the most intelligent way to go. Yet, no one here seems to actually KNOW why they do it other than the manual says so.

I guess the question should be is how big a difference between regular and premium would get you to switch to regular? I think this is more than just speculation because 1) we're probably getting in deep doodoo in the middle east and prices could soar out of control overnight and 2) historically, when this happens the disparity between prices for regular and premium gets bigger.
