I use all my gas from added-in Redline fuel system cleaner. I just added in CRC Guaranteed to Pass today with 87 Shell gas. When I retest for smog should my gas tank be full? O what type and brand of gas? Would V-Power help? I filled up my last full gas with V-Power and Redline. The smog tech said I have unburned fuel due to high hydrocarbons.
So far I've driven every day for 200 miles mostly highway. Would this be enough to burn off the unburned fuel, along with Redline fuel system cleaner, Shell gas, and Guaranteed to Pass so I can pass smog?
