I had been having a problem with my mpg going south and I ran 3 tanks of S1 back to back. Changed the oil today and it was BLACK! I mean it was REALLY black! Heavy gas smell along with that.
Talk about a sound and feel difference with fresh oil! Much quieter and smoother.
Still have not found the economy issue but it has been better lately, but still 10%+ down on what it normally got.
