Fabulous Freddy’s has teamed up with two of the leading Top Tier fuel companies. These companies treat their fuel with specific additives and detergents to help your engine run FABULOUSLY. These additives can help prevent carbon build-up inside your engine. Both Shell and Sinclair are considered Top Tier gasoline. Top Tier gasoline must adhere to a much higher standard than most other gasoline. Although all gasoline is required to contain a minimum quality level set by the EPA, Top Tier gasoline performs at a much higher level by using higher quality detergents to help keep today’s high performance engines running cleaner and longer. Many automotive manufacturers recommend Top Tier gasoline in their vehicles.  We are VERY proud of our relationship with these two FABULOUS companies.
