Tier 1 Gasoline in a term that popped up recently. In the "old" days I had confirmed to my own satisfaction that Gas was Gas and it all came out of the same supply tank at the distribution yard. Recently I was told that there is now a difference in the quality/grade of gas between say a Mobil or Shell station and a convenience store pump.
I buy most of my gas and diesel at Extra Mart (convenience store) here locally and it has all been fine. A little searching on the web is unclear as to whether there is a difference or not. A buddy of mine does quite a bit of haz-mat/pollution control at a local terminal and says that there are now 3 tiers of gas. Supposedly my bike will eventually suffer from running "unbranded" gas unless I use something like Techron regularly.
Has anyone have any words of wisdom on this? TIA Gary
