1. What gas station you use doesn't matter if it is of Top Tiers. What type of gas, premiun like octane 91~, you put matters. Of course 370Zs want premiums.

2. All gas stations get their gas from the same oil refinery. The only diffetence is about detergents put additionally at each gas station (following the gas brand).

3. Sometimes it might be helpful to put fuel system cleaners but remember that it really depends on for whether it works.

That's it. Any other things you just forget. We human cannot feel differences from other insignificant factors. Rather than getting stress for what gas station to use, you'd far better pay your more attention to keep good maintenance/oil changes.

So we can turn this into a dual gasoline/oil debate on one thread? J/K

Yes

more simply, these are just all about 'proper usage'.
