For a few decades I've used Ethanol-Free gas. This week I saw an article about Top Tier gas, never knew about this.
Murphy Express is what I typically use as they have lower prices and EF 87 gas. Then, I read that while cheaper and EF is probably not a good choice since Murphy Express is not a Top Tier.
I'm not a chemical engineer. Looks like Old School stuff I focused on for engines from days gone by doesn't appear to apply to newer engines, and it is OK to use "Corn Squeezin's" in gas today. Seems MBTE (sp?) was squeezed out by corn and better overall. My Outback is a 2022.
One thing I heard about Ethanol probably 30 years ago was that Brazil uses Buffalo Grass that pound for pound produces like 400% more than Corn (a food product.) Is this accurate?
šŗ šŖ - š - ā½ - š : I wonder if most people really go to the gas station based off ratings or just what they socially like or the look appeal like. The bombardment of loyalty point clubs, & product sales, discounts & promotions probably makes people forget a lot about the actual quality of gasoline of comparison! But I think of fuel performance, food, convenience, & also what stations I'm spirited for! šŗ Food is a big influence factor & most people won't divide gas quality, food & convenience. So gas markets who promote, need to focus on their retail store & customer appeal as well.
I guess Murphy Express & Murphy USA is the same for Mogul, Few Pics :
