Yes, AMSOIL is great for dirt bikes. I use AMSOIL motor oils, gear lubes, suspension fluids, and chain lube in all my dirt bikes, ATVs, and SxSs. I spent many years evaluating different dirt bike oils before I decided to use AMSOIL. My favorite dirt bike oils that I prefer to use are the AMSOIL 10W-40 100% Synthetic Dirt Bike Oil (used in my Suzuki and Yamaha trail bikes), AMSOIL 10W-50 100% Synthetic Dirt Bike Oil (which I use in my Yamaha YZ250FX and Yamaha YZ450F), AMSOIL Formula 4-Stroke Powersports 0W-40 100% Synthetic Motor Oil in my ATV’s and AMSOIL 10W-40 ATV/UTV 100% Synthetic Motor Oil in my side-by-sides.

AMSOIL is not sold in most big box stores because AMSOIL wants to maintain the legacy that founder Al Amatuzio introduced, relying on a national network of AMSOIL Dealers to educate customers on why synthetic oil is better than conventional oil. From AMSOIL: We think it’s important that AMSOIL products are available primarily at businesses that offer specialized products and services. As such, we don’t sell directly to national chains because they can gain a competitive advantage that makes it less desirable for local or regional businesses that offer repair, installation or other value-added services.
