Not worried about if its top tier or not. Got a bottle of Redline Si-1 at all times and a dash occasionally of PEA beats any top tier detergent anytime.



You can not get 10% more fuel when you are already getting 100% fuel.

This morning I topped off my Hyundai with Top Tier E0 92 octane Cenex fuel. Top tier AND E0!!

For the OP, I'd say Top Tier fuel first (Costco, Exxon, Shell, etc.) then E0 if you can't find a good Top Tier supplier.

In my tuned Optima, I run Costco 93 octane (E10).
In the wife's Rogue, it's often Costco 87 octane (E10) and sometimes our local Ingles 87 octane (E10) gas due to accumulated gas points.
Additionally, I do an annual Red Line SI-1 gas treatment as well for both cars.

FWIW: The wife's car is our long-haul road car and I always stop at Exxon/Shell stations for Top Tier 87 octane gas.

>> My desired gas would be a Top Tier 93 octane E0 gas for my car and a Top Tier 87 octane E0 for the wife's car.
