They sell hotdogs for $1.50. Put that in your tank.
All top tier gasolines in the U.S. contain 8% Ethanol and no more than 10%. So you would have to buy gasoline that is not top tier. I do not recommend you burn such a fuel in your car.
No they don't they do not show the Top Tier logo or are in the list according to toptiergas.com I drive a 2010 Camaro SS and used Murphy USA gasoline (premium) and for some reason the gasoline tends to drop quickly compared to other gas stations like (Mobile, Shell, etc...) that are in the list of Top Tiers.
Shell is better. It is considered a top tier gasoline. If you google "top tier gasoline", you will find a website that lists which gas companies provide the best gasoline. Shell, Exxon and BP have the most detergent in their fuel. Having said that, Gulf is still a very good brand and you'll probably save a few bucks as well. I also like the Gulf logo better :)
Top level
To say that something is 'top-tier' is to say that it is of the greatest level of quality. A example of a sentence using the phrase 'top-tier consumer' is: We are developing a plan that will market towards the top-tier consumer.
The company gets its fuel from several suppliers. Some can include Marathon Oil Corp. and BP. Road Ranger sells its fuel under the Ranger Fuels name. Ranger Fuel is also Top Tier certified. Top Tier Gasoline is designed to protect engines from the build-up of carbon deposits on fuel injectors, intake valves, and combustion chambers.
No it's a low grade goes against gas companys like Sunoco and Getty. If you have a high end car like Mercedes do not get gas from them
Just checked the Top Tier's website, and it does not list Circle K as one of the brands the sels top tier gas, so I would guess not.
tier
Tier 1 is the top tier... this would includes groups such as Delta Force, SEAL Team 6, 22nd SAS Regiment, etc.
