[QUOTE="lfgt, post: 16296013, member: 196111"] I discuss my situation and fuel I run in detail in this thread: [URL]https://svtperformance.com/threads/new-gt500-owner-any-potential-issues-running-95-octane-mix-on-a-93-tune.1178473/[/URL] In summary the car is tuned for 93 and I am now running a mix of 93 and 100. Mixed in a ratio of 1 gallon of 100 to every 4-5 gallons of 93 to raise the octane at least 1 point just out of fear of getting 93 that is not up to par. The 93 is from Phillips 66 and contains ethanol. The 100 is Sunoco 260 GT unleaded and also contains up to 10% ethanol. Before this tank I was running 95 octane that is on pump at a Harley dealership. They mix the 100 (Sunoco 260 GT) with ethanol free 91 to make 95. [/QUOTE]
