Atlantic Richfield? There's a blast-from-the-past name. Kinda like the days of the old dial-'em-up pumps at the Sunoco station with the 260 petrol. It may have been a placebo, but I swear that my '67 Olds ran better on that stuff. Maybe it was just the driver that did.


On a related note regarding compression, my H-D mechanic said to always run regular in my '04 Sportster and my '08 Deluxe. He said not to bother with higher octane unless I detected any pinging. His point was that the higher grades sat in the tanks in the ground longer and were more likely to have water in the fuel. I think that both of those engines were about 9:1, and neither complained. I do run hi-test in the 2020 bikes, but one is 10:1 and the other is 10.7:1. I do buy fuel for them from stations at an interstate exit because they likely cycle the fuel in their storage tanks more rapidly than other stations.


Of course, all of this is hypothetical until I get one of these fellas to play with.
