Top tier fuel is likely unnecessary. That said, if it does somehow keep the fuel system cleaner, then an occasional fill-up at a non-top tier fuel station will not significantly affect fuel system cleanliness.

I've never had a fuel system failure, and I've always run Arco gas for hundreds of thousands of miles.

FYI- Costco fuel is the cheapest in my area, and it is now Top Tier (ie equivalent to Chevron, Texaco, etc.)

It is very unlikely that cheap gas will ruin a fuel system, and even if it did, fuel systems are easy to service.
