    Top Tier is pure B.S. It's a marketing ploy devised by several oil companies, nothing more. Any national brand and most regional brands are equally good, and there is absolutely no credible evidence to the contrary. Don't get sucked in by advertising.

    Re: GM recomended gas

    I'm not a scientist and don't profess to be one. I also don't see why I'd justify using cheaper gas in my car just to "save" $.03 a gallon. (I have a Costco card and also hate waiting 10 deep in line for the aforementioned 3 cents savings)

    I used to use Techron additive but it dawned on me that: A) it was a pain buying it and installing it and B) it is easier to just buy the right stuff for peace of mind and have to do nothing. I have no reason to spring for that $$ Cadillac intake cleaning service because according to Top Tier Gasoline manufacturers, I don't need it.

    This is like the motor oil argument.......I do not think that they are all the same either.

    Choose your rationale,

    Richard

    C'mon...the performance standard for Top Tier gasoline was "devised" by 6 automakers BMW, GM, Honda, Toyota, Volkswagen/Audi, and the product is now sold by 27 gasoline brands at retail locations throughout the U.S. and Canada.

    Apparently gasoline retailers lacked incentive to incur added cost for undisclosed additives and testing beyond that required by EPA minimum industry standard. "We've felt for a long time that the minimum detergency level set by EPA was not adequate for many fuels on the market," Andrew Buczynsky, fuels engineer at General Motors. So along came automakers' higher performance standard Top Tier, offering participating retailers the incentive of competitive advantage/quality brand image; hopefully, for automakers and owners, the incentive of fewer warranty claims/out-of-warranty repairs related to engine deposits and stuck valves - and longer reliable engine performance.

    I'm with Richard MacGregor, above, on this one.

    The owner's manual on my previous GM car told me to use "Top Tier" fuel. I purchased the car at 26k and sold it about 5 years later with 160k miles. I didn't care where I filled up. I put Techron in about twice a year, typically mixed with two tanks of premium fuel to make a hotter burn. I never had problems with engine deposits or engine performance or stuck valves. Ever. I'll be doing the same with my CTS.

    Yep...Chevron Techron is reportedly the same as "GM Fuel System Treatment Plus," and that's GM's recommended alternative for those not using Top Tier gasoline.

    Re: GM recomended gas

    You're right about the origin of the Top Tier concept -- like President Bush II, I "misremembered." It was the brainchild of several auto makers.

    However, it remains that oil companies PAY to use the Top Tier label, and some simply refuse. That does not mean, however, that their gasoline is inferior in any way. Companies like Mobil use the same types and amounts of detergents as do the Top Tier brands.

    Bottom line -- buy the least expensive national brand available, and don't waste money on labels. Where you buy gas is far more important -- avoid stations with old rusty, leaking tanks that may contaminate the fuel with water and dirt.

    Premium fuel doesn't "burn hotter." It's simply capable of being compressed to a greater degree without igniting. The octane rating is merely a measure the fuel's resistance to detonation -- that is, the higher the octane rating, the harder the gas is to ignite. The compression ratio of your engine determines what grade of gas is needed to prevent knocking.

    Re: GM recomended gas

    So how does one find out if a brand uses this "top-tier" gas? I use Speedway. Mostly because it's right on my commute (I refuse to go even a 1/2 mile out of my way to get gas) I think I generally pay 5 cents more than other gas stations near my house.
