What gas do you all use?
Ive been using Sunoco for every car ive owned so far. And for the Z28 ive been using premium gas which I just realized how bad the 350 is killing my wallet.
So my question is what type of gas do you all use/recommend? Is there any downside to using the lowest grade? Or should I go with the medium grade? Thanks

Re: What gas do you all use?
Really? So im basically wasting money/gas by putting in the highest grade? Damn and I thought I was doing good for the car :P

Re: What gas do you all use?
OK, the camaro/thirdgen manuals say to use unleaded gas 87 aka regular. you can use what you want.
Truthfully Premium gasoline only diffrence is a higher octane rating that will help overcome knocking or pinging in engines. If your engine knocks using regular then use Premium. I use to run premium in my camaro all the time but now I use regular for the main reason it is cheap it doesn't knock.
my thing when it comes to gas is a gas station that guarantees there gas.

Re: What gas do you all use?
Unless your car is modified significantly, or for some reason the ECM has been tuned in a way that requires 92 octane, then you should probably be using the normal 87 octane fuel. There is zero benefit to using higher grades of gasoline in vehicles that don't need it.

Re: What gas do you all use?
it is my understanding that BP is the only gasoline that does not use middle eastern oil . i use BP gasoline when ever possible . i never use CITGO , CITGO is owned by Hugo Chavez . don't know Hugo ? do a search on fox news , cnn & others . drive American ? be American & wake-up .

Re: What gas do you all use?
I can also tell you these tid-bits on gases:
1) Exxon gas stations MUST use Exxon gas - there is no substitute - no Exxon gas at the tank farm means an Exxon station will have no gas.
2) Shell same as Exxon.
3) BP - the concept of BP not using any middle-eastern oil is false. BP themselves may not refine any middle-eastern oil, but their stations use it everyday - same as any and every other station in the US. Amoco (if still branded anywhere) is the same as BP.
Here's an explaination that will help (and is kinda cool and interesting):
Gas comes from the pipeline - I'll use the Dixie Pipeline as an example since I personally know about it as I live on the east coast. The Dixie Pipeline starts in the refining fields of Texas and Louisiana. The oil is refined, and pumped into the pipeline - it is refined by everyone (BP, Exxon, Shell, Citgo - everyone - and it's all pumped into the same pipeline. This is one huge pipe that runs underground in classified location, from the refineries to the northeast all the way into NY state. The fuels are pumped into the pipeline by grade, either regular 87 or premium 93. The grades of fuel are seperated by the one readily available product that will never mix with it - water. They call this a "slug".
That's it - that's all there is to it. There's no seperate pipe for BP, or Shell, or anything else - it's just gas, gathered from refineries from every brand. The light crude comes from any and all sources, from middle east, from Venzeuala, from the Gulf of Mexico - from everywhere (EXCEPT Alaska - Ill explain that later). It's refined in the refinery fields in Texas and Louisiana, and pumped up the line.
Along the way, there are tank farms - large areas where the fuels are stored in tanks. In my area (central NC), there are several farms. Apex NC, Greensboro NC, Selma NC, and many others. At each tank farm station, there are large pumps, and diverter valves - all computer controlled. This is where the fuels are siphoned off, and where the remainder is pumped on up the line. At the beginning, for example, 1 million gallons of 87 will be pumped into the pipe, and a "slug of water behind it, then 2 million gallons of 93, another "slug", and so forth. By knowing the speed and destination of the fuels, and the sizes of the "slugs" that seperate each grade, computer systems pump the fuels up the line through the tank farms. If Apex NC is scheduled to get 250,000 gallons of the 87, when it arrives (know by sensors that sense the "slugs"), the 250,000 gallons is diverted off the line and into a tank at that farm, and the rest is pumped by that stations pump on up the line. It's a continuous 24/7 365 pumping and siphoning up the line, all the way from the beginning (Texas) to the end (NY State).
So, let's say that out of the 250,000 gallons of 87, 100,000 is needed as Exxon Brand, 100,000 gallons needed as BP Brand, and 50,000 gallons needed as "unbranded". So, when it comes off the pipe, 100,000 gallons is fed to the Exxon designated tank where the proper Exxon additives are mixed in, same with the BP - proprietary blend of additives for each "brand". Exxon, BP, Amoco, Shell all have their own blends of additives, and a simple chemical test will tell what "brand" (ie what blend of additives) have been mixed in. The unbranded fuels have a standard mix of additives, but nothing proprietary.
The additives are cleaners, emulsifiers, detergents, etc. They are all different. Any "branded" gas station is under contract with that brand, whether a "company" store or an independant. And all are subject to brand" testing at any time day or night - if an Exxon station is tested and found to have BP fuels in their storage tanks, they can be immediately shut down, have all the fuels in the tanks confiscated, lose their licensing (ie the Exxon sign), and be severely fined ($25,000 minimum) as per the contract signed by the station.
So - in the end - buy all the "brand propaganda" that you like, but the fact remains - we all burn the same gas whether we buy BP or Exxon or Joe Blow's GAS. The ONLY differences is in the additives and the advertising (and the propaganda to make you THINK you're getting American oil or non-middle-eastern oil or NOT Veneualean oil).
Some other interesting facts:
1) "Watered down" - There has never been an instance where anyone ever got "watered down" gas. Think what you will, but it's physically impossible as water won't mix with gas under any circumstances. Thus why they use the water "slug" in the pipeline.
Also, EVERY GAS STATION in the world has water in the tanks, and alot of it! It sits at the bottom of the tanks. You think those lids that you drive over everyday in the parking lot are waterproof? Everyday that it rains, your local station adds water to their gas, sometimes inches at a time! But the pumps are located mid-way in the tank, and the water level is checked every 5 minutes by a computerized system. An underground tank might hold 10,000 gallons of gas, but it will hold 12,000 gallons of volume - the extra having been built into the tank as a water sump at the bottom that the pumphead can't reach.
2) An average neighborhood independant station pumps about 30,000 gallons of 87 and 12,000 gallons of 93 every week.
3) Mid-grade is mixed at the pump at almost 95% of the gas stations. Think about it - 93 + 87 / 2 = 89 ... MIDGRADE! When you choose 89, the pump sucks even amounts from the premium tank and the regular tank - mixing it right in the pump that you pulled the handle from. Even though many stations have many underground tanks, they are usually either premium tanks or regular tanks. Very few places left actually get mid-grade deliveries to them, but it is possible to get midgrade directly from the tank farm.
4) A gas tanker truck is made from aluminum - NOT for the safety from the fact that aluminum won't make a spark - but from the standpoint that aluminum is the lightest weight material to construct the tanker from economically. Why? Because we need to transport the most gallons we can per truck trip, and since the limitation is the size of the tanker and the weight of it loaded - aluminum is used. This allows a tanker to carry exactly 9000 gallons per truck. A tanker has seperators within, and can split a load by doing say 7500 regular and 1500 premium - but it always equals 9000 gallons.
5) If a station can't take all 9000 gallons of a tanker, they are charged a split truck fee by the delivering company - thus they always find a way to get the 9000 gallons to fit, by being very cautious with their ordering - you have to wait until you can hold it, but not too long where you run out before the tanker gets there.
6) On average, every station makes about 3 cents per gallon profit. Yes, only 3 cents per gallon! On a good day, maybe 5 cents. This is assuming they are trying to remain competitive with the other stations within 10 miles of them - there's just about always a large chain with rock bottom prices within 10 miles. But that's GROSS PROFIT, NOT NET PROFIT! Net Profit 99 days out of 100 equals NOTHING - most days it costs a gas station money to sell you gas! Why?
We all use credit/debit cards at the pump. Credit card processing fees for an average independant station are 15 cents + 1% of the purchace per transaction. So you get 10 gallons at $3.00 a gallon = $30. It cost the station 15 cents + 30 cents to process your card. But the station only made 3 cents per gallon = 30 cents! So the station owner just lost 15 cents on you! How many other idiots pumped gas today at that station? 100? 200?
Now, add on top of that the light bill for all those pretty bright canopy lights! No need to have canopy lights if no gas pumps - so that is a direct cost of pumping gas as well.
Think about it next time you pitch a bitch about the gas prices to the cashier (or even the owner) of your local quickie mart - technically, they could make MORE MONEY if they stopped selling you gas! The ONLY people that make any gas sales profits are the oil refineries - when you hear about how many billions that Exxon made last quarter, that's Exxon refineries, not the local Exxon station.
6) Gas expands and contracts ALOT with varying temps - we all know that. Now consider the underground tank at the station, the tanker truck on the highway, and the above-ground tanks at the farm. In the summer, when a station orders 9000 gallons, it's pumped into the truck at basically slightly cooler than outside air temps. BUT - as the tanker is filled, the gas warmes up (empty tanker in the sunshine is warmer than the huge full tank at the farm), so there is actually less than 9000 gallons pumped into the truck, since it expands as it fills. The invoice is calculated based on the truck holding 9000 gallons, which in the warm tanker, is actually only 8600 gallons now since it expanded upon filling and the original 9000 gallons won't fit. Now, the truck drives to the station to drop off, it gets warmer along the way, and expands further. So, at the station, now there's 9300 gallons delivered in theory - BUT, as it is put in the underground tank at the station, it cools, and contracts back down - and since it's cooler in the under-ground tank that it was at the tank farm, when it settles, now we only have 8400 gallons in reality. Paid for 9000, and in the end only got 8400 gallons.
The losses add up quick when we remember the 3 cents per gallon profit that the credit card company ate up in fees!
In winter, it's the opposite, so it kinda evens out in the end - but on a yearly basis, not on a daily, or weekly, or quarterly basis - when profits and losses are measured.
7) There are some very large independants - like Sheetz, 7-11, Kangaroo, Hess/Wilco, etc. These stations can and will use any gas available. They also carry alot of weight in the gas station world. If there is only 18,000 gallons of 93 at a local farm, even if it's been "branded" Exxon by having the Exxon additives ALREADY added to it, if the larger chain NEEDS the gas at the same time a smaller independant needs it, guess who wins? There's really no way of knowing from day to day what "brand" if any of gasoline additives you might get from a "non-branded" station. I've had Sheetz many of times leave me completely empty of gas because they "took" what was branded as my Exxon gas. Sure - they paid a premium to the tank farm to "steal" this gas, but it doesn't help the smaller independant any. Any "unbranded" station can pump anything from bovine methane to sewage to the "best" gas available. But a "branded" station MUST pump only their "brand".
Over the past 30 years I've worked at several chain and independant stations, thus the insight to what happens behind the pump.
OK - took me an hour to type all this - hope someone enjoyed the info!

Re: What gas do you all use?
Oh - I forgot the Alaskan gas explaination...
The oil pumped down the pipeline from Alaska goes right into tankers headed for the far east - the US does not use a drop of it's own Alaskan oil! It's not cost effective to pump the crude to the US refineries in the south, and it's certainly not cost effective to build new multi-billion dollar refineries farther north. It is most cost effective to just put it on a tanker and sell it to the far east (mostly Japan and China), where they refine it themselves into gasolines.

Actually all gas companies use the same pipelines except one. Chevron uses their own pipelines.

FWIW, the owner's manual for my '87 IROC states to use 92 octane.
I don't follow the directions.

it is my understanding that BP is the only gasoline that does not use middle eastern oil . i use BP gasoline when ever possible . i never use CITGO , CITGO is owned by Hugo Chavez . don't know Hugo ? do a search on fox news , cnn & others . drive American ? be American & wake-up .

But wouldn't the knock sensor prevent the car from pinging on low quality gas?
The manual for my bird says to use 87 but since carbon buildup causes octane requirements to go up slightly, and my bird's 21 years old, and I won't be able to hear pinging due to the knock sensor, I use 89.
