Used Shell premium since 2006
I don't recall where I learned that Shell fuel was preferred but did make that change from cheapest available near me.
I do not subscribe to 'its all from same place' or 'only different additives' theories. Shell does have refineries in the USA.
There was a time when Shell fuel commanded a premium price, not now. In SW Florida all fuel stations advertise their regular fuel prices and Shell is the same as nearby competitor fuel stations. I filled up yesterday. Regular was $2.179 and my 93 octane premium was $2.749 before a 5 cent discount per gallon from my fuelrewards.com card. I've had some fuel rewards as high as 50 cents per gallon.
So here is my bottom line: I have used Shell premium since acquiring a used E34 M5 with 165,000 miles on it in 2006. Some 13 years later, that car is one short trip from 229,000 miles. I regularly shift near its redline; and, cruise in a 3,000 to 3,500 rpm range all the time. Never had an engine issue.
