I use the marathon type premium fuel in our plane, each barrel we buy I check the ethanol percent, I am running around 7 to 8% all fuel lines and carb is setup for ethanol but like to keep it as low as possible.

Guess who's getting tax incentives, low-interest or zero interest loans, and big ole grant money to grow them slimy green bugs? Someone's gotta do it.

I just design the equipment and tell em how to keep it running. And back up to my paycheck :)
:eek:

Top tier is real.

Top Tier Gas

New guy on the block...FAME Sammy...


(sell out!) JK

It all has ethanol unless it says its doesn't and I still don't believe it! All diesel has bio-diesel (FAME) in it up to 5% is allowed. Heck E10 can have up to 15% ethanol in it!

When I was young, I used ARCO because it's cheaper. Each time taking the fuel filter off, I pour it out on my hand and always found that it's very dirty. After switching to Shell, I have not seen it's that dirty any more.

Who you callin Ester? ;)

I don't disagree with Sammy, but to clarify, Arco gas is still BP from Madera/ Chowchilla up the Canadian border. Tesoro supplies Arco gas for the rest of central and southern California. Ask me how I know. On the other hand, don't ask me how I know, I just heard from a little birdie.

Arco gas is fine, just run a tank of Techron or BG 44K a few times per year or before your scheduled oil change.

Didn't they pay the automakers for that designation? I'm hoping some Ralph Nader lawyer schmuck doesn't shoot that down and create a class, you know?

Where is this magical place you call Madera/ Chowchilla?
I usually get scared and turn back when I get to Fresno.
AND FOR GOOD REASON!



OK, How do you know?
Oh wait, I wasn't supposed to ask that.

I thought Tesoro got all the arco stations, guess BP kept some for themselves?
IIRC their closest refinery is in Washingtoooon, Cherry Point.

That's a long way to ship gas. I wouldn't be surprised if they bought some from the bay area.

Proves my point. Back in the day, the quality would vary from one station to the next because of dirt and water in the tanks.

And now for something completely different.
Remember that if you have DFI then the cleaners in the gas won't do squat for your valves.

It's more of an additive advertising program. It's real, but still kinda ......

I'm told Cherry Point also, but I don't believe it either.

BP kept AM PM, but licenses it to Tesoro for So Calif.

Tesoro owns Arco brand now, along with Carson/ LA terminal, as you know.

So if you go to an Am Pm in so calif, you're buying Tesoro gas. If you're in No. Calif, you're buying BP fuel.

ARCO gives me gas. I like that.

I lived about a mile from a Chevron station for years. I'd heard a lot of good about Chevron and Techron, so I went to that gas station pretty religiously (it helped that it was super convenient). At some point after several years, I noticed that my vehicle was pinging. I changed to a different vehicle and then rarely noticed any pinging. I then switch to a third vehicle, and noticed that vehicle started pinging. I was running low on gas and had to full up at a super-cheap gas station like racetrack or something like that. It was, at least, a new station. That's when I noticed that my car stopped pinging when I filled up with the gas from another station. I'm sure Chevron is good gas, but I stopped using that particular station. I don't know if they had crappy tanks full of water or they weren't dispensing 93 octane or what, but I never went back.

I'm using a Chevron again, but mostly just because it's the most convenient station for me. This one doesn't seem to be causing any issues.

I figure the quality of the tanks and station is more important than the additives.

From what I gather the Nitrogen they are referring to is contained in the PolyEtherAmine (PEA) they add which is, if I understand correctly, generic Techron.
