Any other differences between Top Tier and normal gas?

Not as far as I know. Top Tier fuel applies to all octane levels they offer, not just premium.

The additives help prevent and remove carbon deposits on engine parts like intake valves and fuel injectors.

This minimizes reductions in fuel economy and engine performance over time due to carbon build up.

About - TOP TIER™

Where I buy it, it is cheaper than regular gas around TV.
I pass the station every day.

They sell Sunoco gas.
441 just south of 42.

Bill14…. You are really going on a tangent to try to discredit the better gasoline. Better and cleaner gasoline plus 40 cents less per gallon are good enough reason for me.

This is a perfect example of why I made the comment I did in post 24.

In what way did I go on a tangent?

In what way did I discredit any gasoline?

Better is arguable. Cleaner may be of questionable value.

Where in the world are you finding gas at $2.37/gallon?? (Costco page says $2.74)

Just something to think about.

Vehicle fuel has ratings called Top Tier. Top tier fuel has special additives that make the fuel better for your car. Most car manufacturers say not to use Non Top Tier fuel in your vehicle.

Sam’s club and BJ’s does not use Top Tier gasoline. However Costco and most other name brand gas stations do. You can goggle this and see who does and who doesn’t.

I have found my gas mileage is significantly reduced when filling up at BJ’s and Sam’s.

We took a trip to Miami this past winter and I filled up at BJ’s the night before. When we got to our destination my tank was just about empty. We filled up with Mobil for our return trip and we had just over a quarter of a tank upon return.
I was driving a Chevy Equinox and my normal mileage is about 31MPG. On that trip it dropped to 27MPG.

I have had other friends check their gas mileage and they also experience a 3-5 mile per gallon reduction in their fuel mileage.

So if you think you’re getting a better deal using the BJ’s credit card and getting an extra 10 cent discount you’re losing it on your mileage. Costco also gives you a 5% rebate when you have their Citibank card and their gas is priced just as good as BJ’s and Sam’s.

I don’t need a bunch of trash talk that I’m wrong. Just do a mileage check yourself and see the results.

If your not sure if the gas is Top Tier just look at the gas pump your buying from and it will say Top Tier on the pump. And as I said earlier you can goggle this to see.

I am a huge proponent of top-tier gas. Top Gear gas contains great detergent additives which in the long run will help you get marginally better gas mileage, while keeping your engine and components clean and running smooth. But to get the kind of increased gas mileage you’re talking about you would’ve had to use a non-ethanol gas. BTW,for others reading this post, higher octane has nothing to do with better gas mileage, it simply retards ignition and is helpful for high compression engines.

My issue with Costco gas is that they don't sell a mid-grade. I use any brand of gas but use mid-grade. To get to that octane level at Costco I'm forced to use premium which costs more than any other mid-grade.

That's really not a valid comparison. It's not possible that the traffic coming back was exactly the same or that you're driving was exactly the same. If you really want to do something that's good for your engine add a bottle of techron (black bottle), to a tank of gas every so often.

I would have to wonder if wind speed and its direction played any impact on the mpg difference you saw. A 10 mph headwind is going to have a significantly different affect then a 10 mph tail wind, thus a fair amount of impact on mpg. JUST SAYING! It’s a matter of physics!

With professional opinions and consumer reports proving that top tier gas is definitely better for the longevity, cleanliness (invisible to all in the normal course of car ownership) and mpg of their car's engine, we can agree that that gas is better than club gas.

However, not everyone cares about the money saved, nor the invisible condition of their car's combustion chamber when they dispose of it, nor about the gas they purchased when a non engine part of the car causes the final sale.

The quality of both gas and car engines have improved sufficiently that untreated gas seldom causes the ultimate demise of most cars, accidents and body age and other parts like braking systems can cause the owner to sell. . . so issues that once were very important to the cost of transportation, now are much less significant to cost and longevity, and other daily issues have taken its place. .

tis the evolution of the economy and capitalistic products. .

everyone has their own opinion, and seldom can everyone agree on any one topic.

good luck to us. .

The reason for carbon buildup in direct injection engines is the fact that the fuel doesn't wash the valves anymore. It's injected directly into the combustion chamber.
