Amsoil Magazine - October 2025

In this month’s edition on page 7, Alex Thompson, our Director of Product Marketing, talks about why gasoline goes bad and what that means for your engine. He explains the main reasons: oxidation, evaporation, contamination, and polymerization. These can lead to hard starts, poor combustion, clogged components, engine knock, corrosion, phase separation, loss of power, increased emissions, and even severe engine damage. The good news is that with proper storage and AMSOIL Gasoline Stabilizer, you can keep fuel fresh for up to a year and protect your equipment, even if you’re using ethanol-blended fuels. AMSOIL’s stabilizer also stands out for its corrosion protection and long-lasting fuel stability.

There’s a great article about hydraulic systems in commercial equipment on pages 10-11. It’s all about how hydraulics make heavy lifting and precise control possible, whether you’re working with excavators, cranes, tractors, or sprayers. The article walks through the key components: pumps, valves, cylinders, reservoirs, hoses, fittings, and filters, and stresses how important regular maintenance is. AMSOIL hydraulic oils get a mention for their protection, cost-effectiveness, and versatility, with options for all kinds of applications. Keeping up with fluid maintenance really pays off in terms of reliability and reduced downtime.
