More About AMSOIL 4 Stroke Powersports-Equipment

AMSOIL 4 Stroke Powersports-Equipment FAQs

What is 20W-50 oil used for?
What oil should you use as primary fluid in a Harley?

For maximum protection, you should use AMSOIL V-Twin Primary Fluid which will NOT void your warranty. You can also use AMSOIL V-Twin Motorcycle Oil which was designed to be used as an engine oil, transmission, and primary fluid. Check here to find the best oil for your specific Harley.

How long does AMSOIL last in a motorcycle?

If also using an AMSOIL motorcycle oil filter, you can run your motorcycle up to twice the manufacturer-recommended drain interval with AMSOIL in the engine and transmission (and primary chaincase for V-Twins) or up to one year, whichever comes first.

What is the best oil for Harleys?

The best all-around motor oil for Harley's is AMSOIL V-Twin Motorcycle Oil which can also be used as primary fluid and transmission fluid.

Is AMSOIL good for motorcycles?

AMSOIL is great for motorcycles. AMSOIL V-Twin Motorcycle Oil is purpose-formulated for Harleys and other V-Twins and resists viscosity breakdown 6X better than Harley's Screamin' Eagle oil that comes stock. AMSOIL Metric Motorcycle Oil provides outstanding wear protection, smooth shifts, and clean performance in metric bikes like Ducati, BMW, Triumph, and many more.

Can you mix synthetic and regular oil in a motorcycle?

You can mix synthetic and regular oil in a motorcycle, but it is not recommended. Mixing synthetic and conventional oil degrades the lubricating properties and chemical additives in synthetics.

Where can you buy AMSOIL motorcycle oil?

AMSOIL motorcycle oil can be purchased online through Authorized Dealers or AMSOIL's website, as well as from local retailers, like many NAPA stores and other auto parts, quick lubes, service centers and powersports dealers.

Where to buy AMSOIL small engine oil?

AMSOIL Small Engine Oil can be purchased online from Authorized Dealers, directly from AMSOIL, and from select retailers near you. As a Preferred Customer, you can save up to 25% on AMSOIL Small Engine Oil and other products.

Is AMSOIL good for dirt bikes?

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.

Why is AMSOIL not sold in big box stores?

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.
