#2 Castrol MAGNATEC 10W-40 A3/B4 Engine Oil 4L

Castol ATV oil

The package of this product comes in a variety. You can buy 1L, 4L, 5L, 8L, and 16L. You can buy in those variances depending on your oil needs. It can also be bought in synthetic and dual lock technology. This product can be applied in automotive gasoline and diesel engines. What the manufacturer recommends is the type of lubricant under ACEA A3/B4, API SN 10W-40, and A3/B3 for ATV use.

 

The pros of using this product include protection to your engine the very moment you ignite the keys. It clings molecules and connects the important parts of your engine. Another good thing about Castrol Magnatec is that it protects ATV engines from wearing before, during, and after each ride.

What’s not good about this product is that there are certain models of ATV that it cannot support such as Kewway Superlight 125.

#3 Motul 5000 4T 10W-40 HC-Tech 4 litre+1 litre free

Motul ATV oil

Motul is a product used as a lubricant with hydrocracked base stocks to make sure that the engines are protected and the life of the gear is extended. This product contains low phosphorus and sulfur so that your ATV can operate in a better condition. Also, Motul is JASO MA approved so it can still work in wet clutches.

The benefits of using Motul is that it prevents your engine from wear and tear. It is used by ATV users who want better-operating conditions for their vehicles. And even if your clutches are wet, this oil will still perfectly work. Some of the packages sold online also come with a free small container of Motul oil for extra use.

The container can only contain up to 4L of oil so if you want to use more during your ride, you have to fill it up or buy additional containers so your supply can last. That’s a con of buying this product. Also, an oil change can be frequent if the usage is too high.

#4 Yamalube 4 Stroke Motor Oil

This is a semi-synthetic oil that is best used for ATV engines. It can also be used for scooters and motorcycles. This oil is produced by Yamaha and is readily available in the market. Each Yamalube container has 4L of oil, which can give you enough supply for more than one ride.

What makes this product a good choice for ATV owners is that it is an all-around engine oil. It’s not just for ATV use but for motorcycles too. If the clutch of your vehicles is wet, this is a good recommendation. The price is not too expensive and the longer and more consistent you use it, the lesser the engine problems you are going to have. Also, it comes with a very good package, making it easier to fill the oil.

The only downside of this product is that it comes with a 4L container only. So if you need more supply, you have to buy more than one container that you can load in your ATV engine.

This product only comes in 4 liters and it’s pricier than any other option on this list. Since it is for ATV and quads used, you should foresee that you will likely spend more money when you buy this oil.

FAQs ATV Oil

How many miles to change the ATV oil?

Usually, you can find the interval of time to change the oil on the product sheet or the official site of the manufacturer. But as a general rule, it’s good to change the oil after 600 miles or yearly. As ATVs are not used as much as cars, the oil gets thicker, and when heated, it might not offer the same lubrication in time.

How much oil does it take to fill an ATV?

The answer to this question is a little tricky; it depends. As each engine is differently built, it requires a different amount of oil. To be sure, I would buy a 4-liter canister and check the level when pouring.

How to change the oil in an ATV?

Changing the oil in an ATV is similar to the process of changing it in a car. 

The first step is to start the engine of the ATV to make the oil inside more fluid. After 10-15 minutes, stop the engine and remove the filter. 

Locate the drain plug, before opening it, put a canister or bucket underneath so the oil will drip in it. Only after putting a bucket underneath, loosen the drain plug and let the old oil drip.

Wait for a few minutes or until the old oil stopped dripping and put back the filter and pour the new oil inside. You can use a funnel to make the job easier. 

You should recycle the old oil as it may be hazardous to the environment.
