They also sit in their cars with the AC blasting here in Texas waiting 30 minutes burning away any savings they would of made at the pump. I rather go to Shell and pull right in and gas and go.
My favorite are the absolute psychopaths that leave their car running while filling up with fuel because it's "hot outside."
Yeah, find out how many gas brands there are in the US, then find out (easy) how many refineries there are blending gas. Not to complicated to figure it out. You take more chances at old stations with water in their tanks than you ever will at Costco.
I pump Costco gas almost exclusively. I wanted to see if it was any good compared to Chevron/76(I don't touch Shell/Arco), and through my research I found out that they perform *weekly* QC checks on their gas to make sure there's no contaminants, when the requirement is once every 3 months. I doubt your 1-attendant-at-all-times gas stations around town do that kind of frequent testing when they have cigarettes to sell and hot dogs to heat up. Meanwhile at Costco I see a new gas tanker filling up the tanks near me at least every other day, if not every day, which means their gasoline is always fresh.
Gasoline is shipped in pipelines in a relatively generic form. Various companies get their gas from the pipeline (which has at least a basic additive package) and then some companies add their own additive package to the fuel. Most of the majors (in fact, ALL of the majors) to the best of my knowledge meet the "top tier" standard (a standard developed by a group of large automobile manufacturers). Some off brands sell pipeline gas. Some use their own additive packages and some conform to the top tier standard. When I last checked the top tier web site, Costco met the top tier standard.
I always wondered about this. I've been told that this does not happen as much anymore. I forgot how or why.
But the manual says 91 is the minimum you can use but if you need performance they recommend 93.
This is an interesting article and the source is Chief Engineer of Ford Performance, Jamal Hameedi. Especially look at point #14:
I have seen this article. So if the engine can run on 87 octane, it can definitely run on 91 octane. It's just that the power will be less on 91 octane.
That's what was said... but the manual says at minimum 91. The take on all of this if you're in a pinch on a 60K plus vehicle that 87 will be ok.... but don't try to pull 8250 pulls or use 87 for too long.
I usually fill 93 octane from BP. I had remember filling 91 octane from Costco once. I would never experiment with 87 octane in this car. lol
Chevron 91 is $4.31 here in Pismo Beach.who is loving the gas prices these days? so here in CA we get 91 octane and now about $4/gal.
