TOP TIER Detergent Gasoline

[smelly]

so are we all using the TOP TIER Detergent Gasoline .... in our cars? Not all stations have iit.
Is using a higher octain than regular, better for gas milage?

I have found that mine runs best on 93 Octane Shell gasoline, don't know why, but it seems to get about 2 mpg better with the Shell, than with other brands

I haven't tried top tier yet, but plan to do so afte a few tanks of non-top tier.
If I can gain a few mpg, as Audog has, and can benefit my wallet in some fashion, I may switch over altogether.

...if you're using Arco gasoline (lowest co$t major here in Tucson, AZ), then you are not using Top Tier.

After reading up on "Top Tier" gasoline, I'm not sure if there really is a benefit or not. My 15 year old Civic has always run on the cheapest gas I could find and it still gets nearly 30 mpg in town and over 40 mpg on the highway. If its all dirtied up inside from the non-top tier gas, then it hasn't hurt it yet. The engine has never been opened, nor has it needed to be.

The mileage benefit might be the ethanol content of the various gasolines. If the top tier doesn't have 10% ethanol and the cheap stuff does, then you will get better mileage with the top tier. Around here, nearly all of the pumps have 10% ethanol stickers on them, even the top tier brands. Pricing around here is largely dependent on the location of the gas station. The closer to the interstate, the higher the price. Even then, the price differential is usually less than $.15 a gallon for 87 octane. Update: I was just out running some errands and 87 octane down the street, near I-75 is $3.65 a gallon for BP. Three miles away, Sunoco is $3.28 a gallon. Both are 10% ethanol and that is the cash price.

My personal feeling is I'm getting screwed no matter what the price of the gas is.

I've been filling up with Shell most of the time cause I prefer their gas. I got some Exxon gas the other day. I've tried 87, 89, and 93. On 93 it does get a tad bit better gas mileage, but nothing to write home about.

On my previous daily driver, '04 Ram 1500, I always got the cheapest gas possible. HEB, Randalls, etc. They all seemed to work fine, but I never did have a look at the internals to see what kind of deposits the fuel was leaving behind. I had 140K miles on my truck before I got into an accident and got my Cruze. I plan to keep this one for a long time which is why I'm using "Top Tier" cat pee gas.

Amen to that.

...Shell here too, but Top Tier is more about 'detergents' content than ethanol content (at least to GM and EPA, et.al.).

I agree w/ ya'll!!! We're all getting nailed, while the the Oil Complanies get richer. To borrow a line form Jerry Reed " They got thy goldmine, we got the shaft!!!"

Crewz, I gotta ask what is "cat pee gas"?

It's just what I call pump gas.
