I have not used my Class B since Aug 2019 due to health issues. I hope to use it next April. I put the green Stabil in a year ago. I did top off the gas tank again this August and added the last of the Stabil. I did notice that the bottle says it lasts 1 year. I bought some of the pink Stabil which is good for 2 years. Should I add it as well now?

Nope, run what ya got. Or get rid of it for fresh fuel. Good news is most low perf efi car engines will run on anything that will light up. Albeit poorly.

Another reason I don’t ever “fill” tanks for storage. Water in fuel is not much of a concern except under extreme conditions or old metal tanks.
Dilution is the solution to pollution and 40 gal of fresh gas topping off 10 or old gas will be better every day compared to 50 gal of old gas.

Oh and run the engine and genny. Better than sitting.
