You don't buy cheap equipment. Why run cheap oil?
AMSOIL has been the leader in synthetic lubrication for over 50 years — the first company to develop an API-rated synthetic motor oil, back when the big brands said it couldn't be done. Today, their products outperform conventional oils in every measurable category: wear protection, temperature stability, drain intervals, and long-term cost.
At Green Spring Tractor, we use AMSOIL in our own equipment. We recommend it to customers not because we sell it, but because we've seen what it does. Smoother hydraulics. Easier cold starts. Engines that stay cleaner, longer.
Frequently asked questions
Here are some common questions about AMSOIL.
Yes — and here's the math. AMSOIL costs roughly 2-3X more per quart than conventional oil. But with extended drain intervals of 2-4X longer, your cost per mile or hour actually drops. Add in reduced engine wear and you're spending less over the life of your equipment.
Absolutely. AMSOIL is fully compatible with conventional and other synthetic oils. No flush required — just switch at your next scheduled change. Some owners prefer a shorter first interval to clear out old oil, but it's not necessary.
No. The Magnuson-Moss Warranty Act prohibits manufacturers from requiring a specific brand of oil. As long as the oil meets the required specifications — which AMSOIL does — your warranty remains intact.
AMSOIL Synthetic Tractor Hydraulic/Transmission Oil is specifically formulated for systems with wet brakes and wet clutches. It meets specs from all major tractor manufacturers and actually improves wet brake performance compared to conventional fluids.
