If he is buying gas where it's the cheapest he is undoubtedly buying low tier fuel. Kind of funny that a guy who helps develop a better fuel that contains Techron which uses PEA as a detergent doesn't buy his own brand. Doesn't say much for the Techron in higher grade Chevron fuel. PEA is also used in Gumout.
"The large corporate stations just add their additive package"
I have never seen a gas station add additives to their tanks when they're being filled by transports.
A Chevron Chemist is going to laugh at Shell products as a Shell Chemist will laugh at Chevron products.
I use to have a Toyota T-100 that at 265,000 miles was having injector issues. I tried a bottle of Chevron fuel injector cleaner without success. A tank later I added Seafoam.............. took care of the injectors, truck ran like new again.
From personal experience my small engine guy has always recommended Shell with Nitro. When I check plugs they're clean. When I put equipment away for the season it's a full tank with some Seafoam for extra protection. When the new season starts........so will my engines.
Boils down to like arguments: Ford vs G.M. vs Dodge
It's my personal opinion; although it may not be cost effective short term but in the long term I think it pays. I have always been a stickler for PM.
