Aspen Alkylate petrol is a Swedish manufactured fuel that has been around since 1988 where it has become an essential product in the Swedish handheld machinery market. Anglo American Oil Company began distributing Aspen around 8 years ago, and more recently, with people starting to take notice of their health and the products, it is starting to become a staple fuel for many professional and personal small engined machinery owners and users here in the UK.
