Motor Oil FAQs

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.

What engine oils are high in zinc?

Oils designed for classic cars, racing, or high-performance engines typically have higher zinc content. AMSOIL Z-Rod is specifically formulated with high zinc levels for these applications.

What does zinc do for performance in motor oils?

Zinc (ZDDP) anti-wear oil additives are heat-activated, providing a protective layer on metal surfaces and reducing friction and wear particularly in high-friction areas. This protection helps maintain engine performance over time, especially in high-stress areas like camshafts and lifters.

What does ZDDP stand for?

ZDDP stands for Zinc Dialkyldithiophosphate. It's a common anti-wear additive in motor oils, particularly important for older engines and high-performance applications. AMSOIL High Zinc Motor Oils offer exceptional protection for engines with flat-tappet camshafts, modified crate engines, and supercharged engines.

How many ounces of oil for 50 to 1 mix ratio?

For a 50:1 oil mix ratio, you'll need 2.6 fluid ounces of oil for 1 gallon of gasoline. This equates to 20 mL of oil for 1 liter of petrol. Use our 2-stroke oil mix calculator to calculate the precise amount of oil needed.

What is the difference between AMSOIL FS vs MS vs LS?

The MS, FS, and LS designations for AMSOIL's European motor oils indicate the SAPS (Sulfated Ash, Phosphorous, and Sulfer) concentrations: Full-SAPS, Mid-SAPS, and Low-SAPS.

Is AMSOIL Signature Series Dexos approved?

AMSOIL Signature Series motor oils meet and exceed industry standards like GM dexos1, Gen 2, Gen 3 and dexos R.

How long does AMSOIL Signatures Series last?

AMSOIL Signature Series oils last up to 25,000 miles, 700 hours of operation or one year, whichever comes first for normal service. In severe service conditions, Signature Series is rated for up to 15,000 miles.

Is AMSOIL the best oil?

AMSOIL is one of the best oils on the market because their products do precisely what we say they will do and they always outperform competing oil products in independent lab testing. Although you'll likely pay a bit more for their premium oils, you'll also save time and money in the long run by using the best.
