A reminder to run Top Tier fuel and avoid cheap gas

I don’t know about today, but years ago Chevron added more Techron to their premium gasoline vs the 87 octane.
 
Here it is mostly Shell and Philips 66, with a smattering of smaller ones.

The ones that are not on the list are Casey's and Sam's Club.
 
I had a mechanic tell me that higher octane fuels can burn holes in your pistons, plus a whole other myriad of problems.

They do great work for me, but this line of thinking is absurd. I've been running 91-93 through my vehicles for years with no problems.
