Buying Guide – Things To Consider When Select The Right 2 Stroke Oils

To land on the stroke oil, you should consider the following:

Bike Manual

The first step would be to check the manual your dirt bike came with. Only by so doing will you understand the specific instructions from the manufacturer about the different types of oil you can use on the bike.

Oil Types

In general, there are specific stroke oils available in the marketplace – including injector-safe oils and premix oils for 2 strokes, as well as weight oils for 4 strokes. Similarly, there are several gearbox oils designed for 2 stroke bikes and air filter oils that work on all dirt bikes.

Differences Between Oils

You need to understand the differences between 2 stroke and 4 stroke oils. The main difference, which most riders are unaware of, does not lie in the weight. The oil you buy will either be injector safe or premix oil.

Most motocross bikes work well with premix oils. This means that you can mix your oil with gasoline before you add it to the gas tank. In the same way, there are different mixing ratios you can adopt.

To this end, you should always consult your bike manual to find the right mix for the best performance. While measuring the oil, always use a measuring jug so that your gas to oil ratio is as accurate as possible.

On the other hand, if your bike’s engine works on auto lube, you should find the right kind of oil. As you do this, keep in mind that not every premix 2 stroke oil will work well with an auto lube system.

What Makes A 2 Stroke Oil Great?

To get to the top 2 stroke oil, you first need to understand what makes one type of oil better than the others and why some brands are more popular with riders across the board.

1. Premix And Oil Injection Systems

For starters, 2 stroke engine oils work best for oil injection and premix systems. However, you might also have to buy different oil for the transmission and clutch of your stroke engine.

2. Lubrication

The primary purpose of the stroke oil is to act as a lubricant along with the bearings at the ends of your bike’s cylinder walls, connective rod bearings, and crankshaft. When you mix air, oil, and fuel, the mixture will flow through the bike’s intake track and right into the cylinder and the crankshaft area.

3. Coating

Last but not least, the top-quality 2 stroke oil will coat everything in its path with the consistently new film required to keep your engine running properly. If you start a 2 stroke when it is cold, you will notice that it releases smoke. This will happen if you’ve added too much of the engine oil, causing it to settle at the bottom of the crankshaft area.

Choosing The Right 2 Stroke Oil

Finding the two-stroke oil for the optimum performance of your bike shouldn’t be too hard. Like with motor vehicles, different bike engines use various types of oils. The key lies in the following:

1. Bike Type

First, you need to check whether you have a 4 stroke or a 2 stroke dirt bike. There are many differences between these types of bikes.

2. Purpose

Primarily, the stroke oil would be used in the crankcase compression of your engine. This crankcase works as part of the larger induction tract. As such, you need to mix the oil with gasoline (where gasoline acts as a lubricant) before using it.

3. Weight Indications

Unlike 4 stroke oil, 2 strokes do not come with weight indications.

Types of 2 Stroke Oil

There are two main types of oils in the 2 stroke category: pre-mix and injector safe. Most of the dirt bikes on the market use pre-mix oils, which you need to combine with gas.

Weight Ratios

Before using the stroke oil, you first need to check the manual from your manufacturer to find out the right oil weight that will work well with your motorbike. After you’ve found the correct ratio, you can buy the oil from different brands.

Final Verdict

Overall, finding the best 2 stroke oil shouldn’t be too hard. We would, of course, recommend that you pick from the list above – which features the leading brands in the marketplace.

However, if we were to settle on one, it would have to be the Maxima (23964) Castor 927 2-Stroke Premix Racing Oil – 64 oz. Apart from being biodegradable, this oil will also protect your engine by leaving less ash than another option would.
