I have always heard that Chevron had high quality gasoline.

 

But, when I fill up at Chevron, my engine is often rattling with light spark knock.

When I fill up at Sinclair with the same grade, there's no knock, and my mpg is slightly better.

 

The oxy fuel season is long over, so I doubt it's that.

 

Is gasoline the same no matter which station you get it at (comes from the same place...?) or are there really differences in the major brands?

 

Your thoughts? (please pardon me if this is a repeat topic)

 

2003 Silverado, 4.3L

 

Thanks- Dan

I wish we had chevron around here. I acheived about an 18 mpg avg with their gas vs like 15-16 with mobil/shell

No Chevron around here either. I've had great results with Hess gas, and I've also been using Sunoco for years.

 

About 5 years back a had a worked Monte SS. I was trying to pull as much timing as possible, but it was pinging pretty good, even with Sunoco 94. For what ever reason, didn't ping with Hess Premium, which is 93 octane. Just my experience though.

Well, I'll throw in my $0.02. Here in the Phoenix area, about a year ago we had a gas pipeline break down near Tucson. So, for about a week there was no gas coming into the fuel farm in Phoenix. EVERY gas station ran out of gas. Which tells me that it ALL comes from the same pipeline. I'm sure that each brand adds its own set of detergents or whatever, but ALL of the trucks (Chevron, Texaco, ARCO, etc) were filling from the same pipeline. So, I use whatever is cheapest. Seems to work just fine. But, if I had to pick a brand I'd choose Chevron because their stations are usually cleaner and they have a better mini-mart. :jester:

In central TX I asked a non-logo'd tanker truck driver who was pumping into Chevron tanks where he gets the gas, he said all the different brand tankers get it at the same place but that when the tanker is filling the additives particular to the brand are added.

 

And this is a pretty good read:

Chevron. Techron seems to keep the engine clean, and around Tucson it's only about 3 cents more a gallon than the no additive Costco. So the difference is the same as the Techron additive, with the plus being that I'm not having to carry it around and add it myself.

 

Yes it's true that the base fuel is all from the same depot that the tanker fills up at.

That's a really good read, and it makes perfect sense. Sounds like it's a good idea to switch it up from time to time. Funny, my wife says the same thing about shampoo, although I never really pay much attention as I'm pretty bald on top. :jester:

I believe in Chevron Gasolines because of the Techron and their reputation. And yes their food marts are rather nice, it just sucks that we don't have them around here in Colorado :jester: I fill up at Phillips 66, Amaco, and Diamond Shamrock, usually the Phillips 66 station here cause they have a great car wash that beats the heck out of any "brushless" wash out there. <grin>

Actually it's ChevronTexaco now.BP/Amoco ,Conoco/Phillips ,ExxonMobil etc.----->ChevronTexaco

 

wow, learn something new everyday. very weird, here all the Texaco stations changed to shell and they take both credit cards (shell or texaco) the few texaco stations you can find (not many) also take shell cards. Chevrons are still around but only take chevron cards. Now I am confused.... :jester:

Right on. I've not had any trouble with shoppin' for best buy. I live in South East Texas and there is an ol' Brownies right down the road. Nasty place but the gas is usually cheaper than dirt. No problems.

 

My father and I were talkin' the other day and he said twice in his life hes gotten a bad tank. Both times were Texaco.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Gas Prices

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.
