Suggestions on Fuel Additive for KIA Optima GDI

[WhizkidTN]

FWIW: I will run Redline SL-1 in a full tank of Top Tier Gas (in my case, Costco 93 octane/E10) annually although I could stand to do this twice a year (run the tank out with the cleaner in it before you change your oil is recommended).

The Redline SL-1 has the most PEA of any over-the-counter (including the reformulated BG44K - the old best standard) treatments back when I looked into it and had great reviews. Seems to have worked very well in all my cars over the last several years.

Disclaimer: I only run Top Tier gas (93 octane) in my turbo Optima but any old gas in the wife's Rogue.

Only if it is the NA version. I would not use that stuff on a turbocharged engine.


Why not turbo DI?

Top Tier gas is only as good as the franchisee's adherence to the maintenance of their fuel delivery infrastructure

Chances are most grands are filing from the same terminal:

*That's excessive - are you using south of the border gas ? ... CRC IVC should be used every 15K miles right before an oil change .
