I have a Murphy USA gas station right around the corner from me. I also have Costco Top Tier gas available, but it's about a 15 min drive. Out of pure convenience, I typically buy gas at Murphy USA. It's cheap and it works. Given that Murphy isn't top tier, would it suffice to use Techron Complete Fuel System Cleaner twice a year (approx. every 5k miles) instead of making the trip to purchase Top Tier gas for each fill-up? For reference, I have both a non-DI Subaru 6cyl and a turbocharged DI Audi 4cyl. Will my injectors and valves remain just as clean if I go the Murphy + Techron route vs. the Costco one? Thanks!
