Since the price gap between Arco and top-tier stations has grown significantly in my area, I have begun to use Arco fuel regularly instead of top-tier. In order to combat the deposit issue, I have also begun using a full bottle of Gumout Regane 2x every 3,000 miles on my Prius. The Prius's tank is 12 gallons, and the bottle states that it treats up to 20 gal, so the dosage is probably on the strong side.
Gumout recommends using their product every 3,000 miles, which I'm sure is safe but may not be truly needed. However, can one foresee any issues with oil contamination? I use 0w-20 synthetic and change at 10k intervals per Toyota.
Thanks.
