Is top-tier gasoline still worth it?

If we can also ban any more Valvoline Restore and Protect threads I am good with this new rule.

Top Tier isn't an additive, but a cleanliness standard (intake valves?). Not all Top Tier gasolines are created equal... and not all non-Top Tier gasolines are created equal, either.
