What synthetic engine oil can I use for my Harley?

Synthetic engine oil not only keeps motorcycles cool but also cools cars and lawnmowers. And as its particles remain suspended and unsettled, it traps more contaminants. This, in turn, prevents particles from settling as sludge to the bottom of your engine to facilitate increased lubrication and better mileage.

These engines are exposed extreme heat and as it’s air-cooled, it tends to get even hotter when it remains idle because of a traffic jam. It can, in fact, reach temperatures that are a maximum of 240 degrees Fahrenheit.

The increased heat leads to a viscosity which in turn affects the oil’s lubricating qualities. Besides, water and all the combustion by-products also form a sludge which is why synthetics have to be periodically changed to eliminate these remove these impurities. Synthetic oils have additives that withstand these containments to facilitate prolonged change intervals.

How to choose the best synthetic engine oil

The next question that springs to mind is with so many brands and types of lubricants in the market, you wonder what oil is best for your Harley Davidson. You need to use synthetics with a very high viscosity index (VI) number, which is the top and low-temperature performance of oils. It is the VI that tells you how much the oil tends to thin out when it gets hot. It is the oils with a higher VI that maintain viscosity better at elevated temperatures.

It’s possible to narrow down your choice by investing in an oil fill cap with a built-in thermometer to monitor your oil temperatures. After recording temperatures of different oils while driving in both highway speeds and low/idle speeds, you’ll realise it’s time to switch to using Amsoil motorcycle oil. This is because you will notice a drop of 30-40 degrees once you start using the oil.
