:) Hi, it basically started with Arco, which used to be Atlantic Richfield Company. A few times that I was stuck buying Arco gas, my truck pinged, dieseled, missed, lost power, ran rough, and got poor gas mileage. My daughter had a car that got about 40 MPG except when she filled it with Arco, it only got 30 MPG. At the time, as a Mac Tools Distributor, I had one shop that also confirmed this. They had a ladies car connected to their test equipment because it was running bad and idled at 600 RPM instead of the factory specs of idling at 900 RPM. They could not find anything wrong with this car. One day while on the machine, it was about to run out of gas. They bought 5 gallons of gas from the nearest gas station, a Texaco station. After dumping the 5 gallons of Texaco gas in the tank, about 30 minutes later the car started idling at 900 RPM and all drivability concerns were gone. They called the owner to ask her where she bought gas for her car and she said Arco. As a shop foreman at a Ford dealer, I road tested with many customers who's vehicles didn't run right and our test machines found no problems. I instructed my customers to buy name brand gas and by the second tank, their drivability concerns were gone. Watching a no-name tanker at a Von's market gas station, I asked the driver who he delivered to. He wouldn't tell me. Another time I was at the same Von's, buying food not gas, I asked the driver about the gas he was delivering. He told me that it goes to all of the discount / no-name gas stations and Arco.I asked him what is the difference between what he delivers and the major brands. His words were that this gas has little or no additives and the filtering was poor compared to the major brands. Then I asked if he burned it in his own cars. He said he wouldn't use it in his car and neither would any of his co-workers. While on a road test with another customer, I questioned him about what gas he was using. After telling him some of my history, he told me he was actually an engineer for Arco. He said that their gas is regulated to be exactly at the lowest level by government standards; Never higher and never lower. He also said that Arco gas never has what they call Sweet Crude. Meaning that they never get the good stuff.
I have owned many vehicles, and unlike many that we saw in the shop, I never replaced my fuel filters. Buying good name brand gas, I never had clogged fuel filters on any of my cars. My 1995 Thunderbird went for 10 years never having a fuel filter replaced and it was given to a family member. My 1996 Explorer was driven for 97,000 miles before I sold it and it never had the fuel filter replaced. I have one exception and that is my 2000 Lincoln Navigator which had one fuel filter replaced after I got home from my 10,000 mile 50 day Alaska trip. Alaska is known for bad gas. A lady who owns a camp ground with a gas station told me not to buy gas from her pumps because she wanted me to make it back home. She stated that once, she filled her tank from her own pumps and had to have her car towed to a shop, drain the gas tank, and flush out all of the lines, and rebuilt/clean out her carburetor.
Note: my Lincoln has over 125,000 miles on it and still has the original spark plugs. Runs great. I replaced one IAC valve on it. Oil changes every 5,000 miles. Trans service every 30,000 miles and air filter as needed.
I chose to buy from Shell, Texaco, Exxon, Mobil, Chevron, 76, Etc.
I do not buy from Arco, Von's, Albertson's, Costco, Sam's Club, Walmart, Joe's Dairy, or any other independent / no-name gas stations if at all possible.
My BS flag is flying a full staff on this one.
The type of gas will not control idle speed. The ecm does. If the ecm has the idle set to 900 RPM it will idle at 900 RPM no matter what gas is put in the tank.
If for some reason the idle is low for whatever reason the ecm will open the IACV up until it idles at whatever the ecm idle speed is set at.
OP: Sorry, that's not anti seize on the plugs. It's burnt on oil.
The ceramic is not chipped on that plug. It's carbon that is chipped off. Much like plaque on a tooth.
Bens picture shows exactly what happens when anti-seize heats up on a plug.
