Gas prices where i live is getting expensive. I was wondering what type of gas most of yall are using. im using premium right now and its costing a lot.

thanks in advance

RHMax

How much cheaper would it be if you use lower grade? Does it matter that much? It still cost $2-3 more per tank for premium, regardless of price.

I currently use shell 93 octane.

Premium just hit $3.00 here in miami

Nothing but premium - 93 octane.

I usually get 93 from any well known gas company - Exxon, BP, Shell, Citgo, etc. I usually stick away from the no-names such as Sheetz, and them Mom n' Pop places.

Ah yes, we couldn't end a week without yet another fuel thread!

Check the fuel and lub section; you'll get a much better feedback.

I agree with RHMax
Mathematically speaking let assume you drive 15,000 miles per year and also assume you get 20 mpg. That means you will burn 750 gallons of fuel per year. Price difference from regular to premium is about $0.20. That's only a savings of $150 per year to burn regular.

RHMax

The saving is the same whether gas is $1 a gallon or $3 a gallon.

premium here all the time. On the Louisiana coast I'm lucky if i find $3 ....

I read an article that gas this summer is expected to jump up by 10 - 15 cents in the comming weeks and by aug. by as much as 25 cents. Man o man i remember when gas was under a dollar......... and i'm not that old.

dla

Absolutely, and I could easily find other ways to save $150 per year and still give the max premium.

regular and premium occasionally
premium gas right now is 3.17 a gallon where i live
i really dont think it matters that much unless u wanna be **** and get into minor details

93 forever, force of habit...and they say stick with one grade forever.

arkiemax

does it really matter want octane you run. I use 87 and get 27 mpg, mostly highway. I get good performance and I don't drag race. Though I like too dump the throttle and listen to my fujita

It sucks but I use nothing but premium...

gmc74

In a nut shell, nope... as long as it performs well and doesn't knock. 3 years and 66,000 miles later, my 04 has seen nothing but 87 octane

just use 87 then. It DOES matter if you're switching back and forth like that.
always changing your detonation timing is far from "**** and minor details"


I recently switched back to SAM's gas 93 (which is supplied by exxon). I saw improved mpg but like some other 6th gens, it's getting loud when idling hot.

I used BP 93 the last year (cleaner Ultimate blah blah). But I figured I would save $$ and try sams again. I will try Sunoco 93 for a few tanks. If the noise persits, I'm sticking with sams.
but always 93.

Nismo, I posted elsewhere that BP is dropping Crystal Clear Ultimate in all markets except around their refinery at Whiting, IN (just East of Chicago). So the reason to use Crystal Clear in your area no longer exists.

I agree with your point that you don't want to be switching back an forth on gasoline grades. It reportedly takes the computer in your VQ engine about 300 miles to fully adjust for a new octane -- and the difference in the adjustments needed between 93 and 87 is much more than the difference between 89 and 87 -- so there is more adjustment needed to fully make that change.

SilverMax_04

All good points GMC. Here in Colorado I run 85 octane regular (read the owners manual). If you wonder why this low octane gasoline works in a VQ engine, read the Octane at Altitude post (# 6) on this thread:

When I drive East (have not driven West, yet), I buy the cheapest grade of gasoline (but not unbranded gasoline). In Iowa and parts of Nebraska, that is 89 octane mid-grade gasoline, blended with 10% ethanol. Now it looks like all gasoline will eventually be blended with ethanol (dumb idea). So (unlike GMC) I can't say that my Max in 35 K miles has only seen a single octane. I even did a test to see if Premium produced better highway mileage than regular -- but that was before I found that it took the VQ engine about 300 miles to adjust to a new octane in the tank.

My point continues to agree with GMC's: so long as the engine does not knock and you do not race or frequently call for WOT, just burn regular gasoline. If you race or frequently call for WOT, then stick to premium. It also appears that regular gives better highway mileage.
