Techron is what chevron puts in its gas, its also sold in bottles.

Its 1 of the additives for fuel that actually works.

You can purchase them at CostCo. They are actually relatively cheap in
price.

If the "loud" sound is under the hood, it could be a bad hydrostatic fan
clutch (or one that's going bad and sticks when it's cold).
