Aspen alkylate petrol

[pvb]

I’ve left the Aspen in my mowers carb for at least 6 months every year for the past 7 years and didn’t have any problems.

I've left regular fuel in my mower's carb, and my strimmer's carb, and my hedgecutter's carb, and my chainsaw's carb every winter for years and didn't have any problems.
