Best Motorcycle Oil Wet Clutch : [Top 5 Picks For 2021]

Best Motorcycle Oil

Many people often tend to use any engine oil without realizing that there are differences between car oil and motorcycle oil. It is not a good practice as the bike engine loses its performance and longevity over time.

That is why we need a special and balanced formula to keep the engine cool and increase its efficiency. Keeping the fact in mind, I have researched and found the best motorcycle oil wet clutch.

From economical to expensive, 2-stroke to 4-stroke, water-cooled to air-cooled, I have reviewed different products to meet the demand. Decide whether you want a full-synthetic, semi-synthetic, or non-synthetic oil, and order one from list below.

Have a look at my top picked wet clutch motorcycle oils:

  1. Mobil 1 96936 20W-50 V-Twin Synthetic Motorcycle Motor Oil – Best Overall Synthetic Motorcycle Oil for Wet Clutch
  2. HONDA 08C35-A141L01 Honda Pro GN4 Motor Oil – Best Budget Oil for Motorcycles
  3. Maxima 41901 MTL-R 80WT Motorcycle Transmission/Clutch Fluid – Great Option for Both Wet Clutch and Brake System
  4. Lucas Oil LUC10710 10W-40 Semi-Synthetic Motorcycle Oil – Best motorcycle oil with a semi-Synthetic formula
  5. Maxima (349128 Premium4 10W-40 Motorcycle Engine Oil – Best Non-Synthetic Motorcycle Oil for Wet Clutches

What Are The Viscosity Ratings For Wet Clutch Motorcycle Oil?

Before we begin, you should know that most motorcycle manufacturers recommend a few selective viscosity ratings. For different types of bikes and their internal systems, the ratings vary. The four most common viscosities are 10W-30, 10W-40, 20W-40, and 20W50.

But what do they mean?

Low viscosity means that the oil is thinner, and vice versa. Both thin and thick oils have advantages and disadvantages. Thinner oils are responsible for reducing friction in the engine, and they are more porous. Also, starting a motorcycle engine in colder regions, such low-viscosity oils are better performers.

On the other hand, thicker viscosity oils are great at maintaining film strength. As a result, it can perform better at extremely high temperatures and loads. You have noticed that the numbers have a format like XW-XX.

Here, the ‘X’ related to ‘W’ indicates how thick the oil would become at zero degrees Fahrenheit. The same meaning applies for the ‘XX’ part at 100 degrees Fahrenheit. Let’s have a look at an example to understand it better.

A 10W-40 grade oil stays thinner and operational than a 20W-40 at lower temperatures. Again, a 10W-40 stays thick and keeps the engine cool at higher temperatures than a 10W-30 oil.

So, you should check the owner’s manual and buy the motorcycle for an oil wet clutch accordingly.
