I've ran Sunoco for quite a few yrs. now. Prior, I ran other stuff obviously but that was yrs. ago, prior to this truck too.

My truck seems like it ran further (better MPG) what few times I've used Shell. Shell is actually a GM recommended fuel too that meets some kind of standard. I know their other others GM-approved fuels too, prolly due to their additives. Shell is only name I remember, yet I forgot where I read that. It was some time back, Car Craft, Hot Rod , or 1 of the other rags.

I won't use BP now, not that I did before. I know of others boycotting BP as well, they deserve whatever punishment they get. Don't tell me how it hurts individual store owners, the issue is w/. BP as a company.

 

I use Shell 93, only because I saw somewhere that SKeet uses it and I want my truck to be as fast as his! LOL

That and its close to my house. But I just started that, Up until like 2 months ago, I never cared where or why, just wherever I was when I was on empty. Now, after 2 fuel pumps, I try to keep the tank half full at least, and I try to use only 1 Fuel brand. I've had bad gas from Valero, plus I got fired from Valero once so I boycott them anyays LOL.

I try to stay away from any station that has a fuel truck at it filling up the tanks, too much **** floating around in there

 

I apologize, I didn't read the entire thread and don't know if it has already been stated that ALL GAS at a given octane IS EXACTLY THE SAME except for the additives.

I will use any top tier gas and use Lucas additive (whether it works or not)

 

Shell/Texaco has had issues with high elemental sulfur in it's fuels which can cause premature failure of fuel system parts. mostly fuel pumps and fuel level sensors......ask me how I know.

What is TOP TIER Detergent Gasoline?
TOP TIER Detergent Gasoline is a new class of gasoline with enhanced detergency. It meets new, voluntary deposit control standards developed by six automotive companies that exceed the detergent requirements imposed by the EPA.

Where Can TOP TIER Detergent Gasoline Be Purchased?
The TOP TIER program began on May 3, 2004 and many fuel marketers have joined the program and have introduced TOP TIER Detergent Gasoline. This is a voluntary program and not all fuel marketers will offer this product. Once fuel marketers make public announcements, they will appear on a list of brands that meet the TOP TIER standards.

Where Can I find the Latest Information on TOP TIER Fuel and Retailers?
On the web, please visit www.toptiergas.com for additional information and updated retailer lists.

Who developed TOP TIER Detergent Gasoline standards?
TOP TIER Detergent Gasoline standards were developed by six automotive companies: Audi, BMW, General Motors, Honda, Toyota and Volkswagen.

Why was TOP TIER Detergent Gasoline developed?
TOP TIER Detergent Gasoline was developed to increase the level of detergent additive in gasoline. The EPA requires that all gasoline sold in the U.S. contain a detergent additive. However, the requirement is minimal and in many cases, is not sufficient to keep engines clean. In order to meet TOP TIER Detergent Gasoline standards, a higher level of detergent is needed than what is required by the EPA. Also, TOP TIER was developed to give fuel marketers the opportunity to differentiate their product.

Why did the six automotive companies join together to develop TOP TIER?
All six corporations recognized the benefits to both the vehicle and the consumer. Also, joining together emphasized that low detergency is an issue of concern to several automotive companies.

What are the benefits of TOP TIER Detergent Gasoline?
TOP TIER Detergent Gasoline will help keep engines cleaner than gasoline containing the "Lowest Additive Concentration" set by the EPA. Clean engines help provide optimal fuel economy and performance and reduced emissions. Also, use of TOP TIER Detergent Gasoline will help reduce deposit related concerns.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.

any of these work for GM.

 

sweet! i see my QT on that list... What i have always done is find a good gas station and stick with it...

 

Well guys I just found out that some stations dont even have 91/93 octane! They say they do but its really 89 octane. To answer yall's question I run Texaco or Chevron cuz of the techron. Lucas fuel treatment as well. Iv'e had my intake off and have seen the tops of my vavles and after 150,000+ miles there still shiney so.....

 

Shell 7yrs now and try to keep it that way.

Once a in a great while i stop at race track when i really need to fiil up. my only 2 stations where i fill up gas.

Never did like Chevron never will.

 

i've never looked into fuel this much but just out of curiosity has anyone actually seen like a test review on the difference between 89/93 in a vehicle? Maybe some actual numbers off a dyno or something between the two.
