gas choices, who uses what

[bjoehandley]

Anything but Clark, as long as it's cheap.

Cheapest I can find, Sheetz, Hess, mobil, sunoco. 87 octane. Put premium in it a couple of times and it was a dissapointment, milage dropped ALOT.
Hmmm, I wonder if thats what happens every once in a while, the suppliers are over supplied with premium and put it in the regular tanks just to get rid of it. Alot of stations around here seem to have sales on preimum every so often where they knock like .10 a gallon of the price.
I've noticed that over the past few years our vehicles take a really big hit in milage for no reason every so often for about a month or so, then go back to normal. When we fill up on say NJ the milage goes back up to normal ranges then back down when we refil here later on in the week.

What ever is closest when i need gas, usually 87 octane.

 

[casm]

87 and usually Shell or Chevron as their gas seems to be the most consistently decent. 76, Mobil, Arco, etc. have given me too many 11mpg tanks to use them in anything other than an I'm-running-on-fumes situation.

 

[JohnnysXJ]

@5000ft 85 octane runs just fine...and there is sometimes a 15 cent difference between 85 and 87 at the pump...thats enough for me....most stations here are either Conoco or Phillips 66 (local monopoly fuel distributor) so its at whereever is cheapest.

 

[Wow]

Usually I get shell just because it's easiest for me.

 

[Quarterwave]

I find my 93' 4.0 runs best on Mobil 89-grade. Don't know why, but it seems to like it the best.

 

[AJ-MJ]

Cheapest and lowest octane :laugh3:

 

[wrecklaw71]

amoco or shell 89 if possible, if there's nothing else I'll use marathon, sunocoetc.. but I try to stay away from off brand station's mainly because i dont know how there tanks are there are only a hand full of refineries, alot of gas problems come from poorly maintained tanks etc...

 

[53guy]

read your manual and see what it says to use. i've got a 99xj and it says to use 87 octane. your motor is designed to run on a specific octane and if you run higher, it just doesnt burn all the way, so pretty much youre gonna be running rich all the time unless you've modded your engine greatly. just my 2 cents

Pemex

:01of5:

 

[Psyker]

Hmm, i usually use either BP (which i didnt see on the list) or chevron, as they are convient and usually not to bad in price, sometimes wally world.

 

[scoobyxj]

I usually run what ever is cheepest. I used to have pinging in the hills on the road to my house, but I switch to a 195* T-stat, and I haven't had any problems sence. Oh I run 87-89 which ever is the stations lowest.

 

[prb24]

87 octane Sunoco or Mobil, whichever is closest. I've been sticking to Sunoco 'cause they've been cheapest @ $2.19/gal.

I use 87 octane, usually from wherever is cheap, but I noticed something recently. I had posted a while back about pinging and oil level (I blow alot off the top of the motor and thought that pinging might be related to oil level). However, recently I had the gas gauge down to the bottom and stopped in the local Corner Store. I spent the next few days pinging like crazy. I was thinking about doing something about it but didn't get around to it. The gauge was down again (17.7 mpg) so I filled up at the nearest station: a mom 'n pop outfit. No more pinging!! So far, for about 3 or 4 tank-fulls, I've avoided Corner Store and, so far, no pinging. Not scientific - but as long as I'm not pinging, I'm happy.

[hackedxj]

stolen gas.........if it gets any higher lol.

 

[75SV1]

I try and use Marathon. I use to use CO-OP gas. I'd get +2mpg on the Highway with it. The place closed down a year ago. I noticed this increase on the Jeep Comanche and a 96 Ford Contour several times. THe owner always said his gas did better milage wise than others.

You all do realize the just about all the gas you buy started out as generic fuel that is pumped thru a large network of gas lines that are owned by two companies, chevron is one, don't remember the other, they don't sell gas, just own the pipes, pumps and depots. They pump the generic fuel to depots in various regions where the retailers pick it up, take it to their facility and add their 'stuff' to make it their product... The fuel that is pumped from some out of state refinery goes thru the same lines no matter what the refinerys owners name is. Now if you live close to a sunoco, mobil or chevron refinery you might be getting their stuff direct but most of us live pretty far away from them. The Hess refinery in NJ delivers all their fuel from their refinery direct to hess stations within a certain area, usually 80mi radius, any futher it's cheaper to pump it to a depot. The generic brands usually have some additives for winter fuel, cleaning, octane, etc w/o the brand name. The magic of branding though is not done at the refinery but at the brand name's supply point, usually just big tanks for storeage that they continously fill from one end, mix in their magic and take out the other end. Exxon is an example, they chop up the tigers [an endangered species BTW] and put that in, hence the red color of their gas :laugh3:
As far as I know there is only two grades of gas, low octane and high octane which is usually mixed at the pumps but alot of new stations now have three tanks due to the disparity of fuel prices, sometimes they can get a better price on premixed mid grade from another supplier. Some of the gas n go type stations around here do that. On the old sunoco pumps they had a dial on the side for the grade, all that dial did was operate a metering valve on the pump and move a slider to get the right price to line up. Anyone noticed the price spread between regular and preimum has narrowed considerably lately. Used to be .20 a gallon between, now it's about .08-.10 cents.

I always use Kwik Trip gas. They are a very busy gas station and go through alot of gas. I see a tanker there everyday. I use 89 octane with 10% ethenal mixed in to help support our farmers who supply all the milk I drink. LOL. My 85 wagoneer with a 2.5 four cylinder runs excellent with it along with my wifes 97 mercury tracer. I have never had a problem with their gasoline.

 

[cosnowrider]

Shell, no greater than 87 octane. Anything higher in octane is usless at this high of altitude, and higher. Plus grand-ma gets paid royalties from an investment in shell long ago.
