Top tier gas question

[gimpy]

I know this debate goes back and forth like a Ford vs. Chevy debate, but some insight from other which brand has worked better for people.

My options are a little limited in my location, but there are 2 stations that carry different brands that are top tier.

Option 1: Exxon
Option 2: CITGO

Yes there are numerous other stations around, but I typically use a Sunoco carrier. Why, because I don't have to wait to use one of the 2 pumps at both option 1 and option 2.

Just hope I'm not the only person who wonders this on the SHOforum.

Does anyone else have any insight or feelings towards this?

Shell 93 has worked best for me.

Shell 93 $3.09 better mpg maybe 1-2, citgo. 40 cents less per gallon 2.69

I'm using Shell 93 as well.

 

[RamAireTransAm]

using mobil or exxon gas , my wifes 2013 turbo malibu picked up a little over 1mpg after about 8 tanks from switching to anyones 93 to mobil 93.

I didn't realize that we don't have 93 octane here until I bought my SHO. 91 is as good as it gets unless you buy 101 octane at the specialty store for $4.50/gallon.

Meeehhh...

I really hate waiting for gas at the Exxon/CITGO pumps (plural being used lightly, there are exactly 2 pumps)

The place definitely needs to get out of the 80s. Heck, even the pumps themselves appear to be old...real old.

Guess I'll stick with Sunoco

Seems to be a good rule of thumb to run a lower octane tune in the winter than in the summer, especially with winter gas in play. If it drops regularly below around 50F where you are at, safest would be, for example, run a 91 tune with 93 gas. The hotter the tune, the more important this is.

As for fuels, quality varies for sure. The most recent reformulation of Shell 93 seems to be a clear winner tho. Regardless, if you cannot find a Top Tier station, be sure to use a high volume/turnover station. Don't need fuel rotted in-tank.

At this point mines still a daily driver PP with no engine mods and I bounce back and forth between 89 and 91 on weekly fills. I don't know the reason or the logic behind this, but on the dash indicator I seem to get 2-3 mpg better mileage using the 89 octane. The average drive is 50 miles/day, 2/3 highway-1/3 suburbia and the little pedal on the right tends to be heavy.

That was me belief also.

I'd load a 89/91 tune in and still get 93 gas for the colder months. November through March

Thought I was being strange as I never looked into the actual reasoning for it.

I am not sure why, but the GTDI engine behaves a little differently in cold weather. Knock Retard definitely goes up with winter fuel, whereas you might not have any with summer fuel. This is by itself not dangerous, you'd think. But since these engines are not particularly detonation tolerant, caution is the better part of valor ...

hoping more for 4 than 12, if at all

 

[rubydist]

my experience is that any of the top brands e.g. Exxon/Mobil or Conoco/Phillips are going to perform similarly and are significantly better than any of the discount or house brands and therefore worth the extra money/time/hassle to obtain.

I run Costco 93. It has detergent and the SHO seems to like it. It is also 15-30 cents less than Shell or Exxon.

 

[DerricksSHO]

I can even tell the difference in the way my car acts in running Shell to BP and both of them are top tier gas stations ive not put BP back in my car but have used Velaro gas and she seem to like that too.

 

[Sholab1]

Shell when going over 200 Miles for the mileage. Citgo other times. Higher turn over on Storage tanks at Citgo always packed and 2.65 for 93, Shell 3.19
Gas mileage is better on Shell. Work pays for my Gas, but I get taxed on what I spend, can not beat this perk.
I still look for the higher quality fuel. in 3 months lowest I put in was 92 ,

I keep a listing of Top Tier Gas in Car when traveling.

Most gas comes from the exact same port, difference is the additives which is literally a gallon bucket of whatever brand you are buying that goes into the tanker with the fuel. For instance, I purchase my gas from 2 different companies, they both purchase it from the port and deliver it to me, they do of course buy it in "blocks". By blocks, I mean they purchase so many thousands of gallons when prices appear to be at their lowest and then I purchase it from them at the daily price, if that is lower than what they purchased it at then they lose money, if higher then they make money.

If I wanted, I could open my tanks and pour in a bottle of Techron or Shell's nitrogen enrichment formula and have identical gas to them.

Now the company that buys in blocks is where the difference comes from, when you see a company that has their gas much cheaper than anyone else, they use bad wholesalers and thus usually have worse gas. This doesn't apply to places such as Costco and Sams since they literally make almost no profit on their gas and sell it at the regulated lowest price possible. Gas prices are federally mandated which means places can't sell the gas cheaper than the lowest available daily purchase price, I believe the lowest they can go is .03 cents above but I could be wrong, it has been a little while since I was certified.

I try and stick to shell or BP unless they are out or I'm out of the local area. The she seems to like those the best. My RX-8 loved BP it was a different car when I ran anything else in her.

I definitely try to keep the Top Tier designation, and most major suppliers carry this even though it is a voluntary cooperation program. I have a 93 Tune and around the DFW area not critical where I got almost in trouble last year was coming back from Ford Nationals. Coming through Tulsa the best I cold find was 91. I spoke with Anthony and Jaime at LMS and got talked through one tank. I used the 91 as a ONE TIME fuel to get back to Dallas but was told expect decreased performance, and weaker fuel economy. They were right, This year I will bring my tuner with me and possibly keep a 91 tune file load since the predominant fuel along my route is 91 at least through AR/TN/MO. I will keep the 91 tune load but if I happen to find a 93 station I will gorge like a lion on a Impala.....the four legged one not the Chevy.

That being said I more concentrate on the 93 and Top Tier designation and have been pretty lucky with Chevron, Conoco, Costco, Exxon, Philipps 66, Mobil, Texaco, Shell although last resort with their ungodly prices, Sunoco and Valero.
