Top Tier® fuels is a standard that exceeds minimum EPA standards. So what does that mean for the consumer?
Fuel grades; Regular, Premium or midgrade are NOT about quality.
Fuel Grades have to do with Octane.
Manufactures do recommend octane requirements and to use the wrong octane can result in SERIOUS engine damage to some vehicles. Be sure to follow your manufactures recommendations.
Top Tier® fuels are designed to clean your engine while you drive from deposits that would cause loss of performance. Clean injectors atomize fuel better. Detergents that clean deposits that accumulate in the intake air streams, like carbon from EGR systems will ensure your engine has maximum air flow for power, and prevent valves from sticking. Also additives that minimize carbon buildup in the combustion chambers with help minimize spark knock due to increased combustion pressures which can result in lower performance and in some cases, engine damage.
Store bought additive can help too. Many are available readily in retail outlets and fuel station convenience centers. Some even allow you to choose your 'ad pac' at the pump! But if you know that Top Tier® is readily available, and you don't have add it on your own, then you simply have to identify who sells it.
Nearly all name brand fuels can be considered Top Tier®. Top Tier® also has a website, http://www.toptiergas.com that has a list of stations that offer Top Tier®.
So now you might wonder, "What does this cost?"
Many consumers by from the lowest price, thinking I will get the lowest grade at the lowest price because all gasoline is the same. This type of thinking will help keep me busier, and in the long term, cost the consumer more for repairs.
Top Tier® fuel prices may be much less than you think! Often the differences is penny's per gallon and little more than a $1 more per tankful. Of course there is quite a variety of additives available, and the cost will vary. You may want the absolute best add pac, and you may find you pay more.
Just as if you may prefer non GMO Organic foods to the lowest cost, so you may prefer premium fuel additives. Each fuel supplier has their special additives. If you are concerned, I recommend you check each candidate to see which you like best!
For me, Top Tier® meets the need of keeping your engines performance and economy at its best!
