Today, we're going to show you how to mix the 2-Stroke fuel for your large-scale RC car. Just like a real car, using the right products is essential to keep your RC car performing at its best. So let's get started!

 

Let’s get the safety stuff out of the way first:

• Only use containers approved for fuel. Petrol is a volatile solvent, you can’t just put it in anything. 

• Mix only in well ventilated areas – we’ve got an extractor fan in here so we’re good

• Avoid skin contact 

• Protect your eyes

 

Now, let’s get mixing!

 

When it comes to oil, don't settle for anything less than a premium performance brand. You want to use a high-quality oil, like what you'd use in a 2-stroke motorbike. Don't be tempted to use the cheap stuff you might put in your lawnmower; your RC car deserves the best. Check the link in the description for some recommendations. 

Moving on to fuel, it's crucial to choose a good quality unleaded petrol with an octane rating between 91 and 98 RON. This ensures optimal performance for your RC car.

 

Now let's talk about mixing the petrol and oil to make 2 stroke fuel. The most common ratio is 25 parts petrol to 1 part oil, also known as 25:1. 

 

There are many different opinions here, but we’ve found skimping on oil doesn’t really give much more power, but it does wear stuff out faster. For the best balance of performance and longevity, stick to 25:1.

Another way to think of it is as you having 26 parts of something – 25 of them are petrol, and one part is oil.

 

To achieve this ratio, for every liter of fuel, you'll need to add 40 ml of oil. So if you're mixing 2 liters of fuel, you'll want to use 80 ml oil. For 5 liters, it's 200 ml, and so on.

If you want to use a mixing bottle, it can make the process very simple. Locate the fill line that corresponds to the 25:1 ratio. I suggest marking the line with a sharpie because they can be quite challenging to see unless you're in the right lighting.

 

Here's how the mixing bottle works: Fill the fuel chamber up to the number one line and do the same for the oil chamber. If you only fill the fuel side up to 0.5, make sure to fill the oil side up to 0.5 as well. Then, combine the contents by tipping the chambers together and give it a good mix.

 

Remember, the mixing bottle is solely for mixing purposes, not for storing the fuel long-term. Always transfer your fuel into a proper jerry can for safe storage. The storage life of mixed two stroke fuel is roughly 3 - 6 months depending on climate and the container. It's also important to drain the buggy’s fuel tank after each use to prevent it going stale in the tank.

If you don't have a mixing bottle, don't worry. There are other options available. You can use a measuring cup or a squeezy pack. With the squeezy pack, open up the smaller chamber and gently squeeze the bottle until you have 40 milliliters of oil. Then, add that to your 1 liter of fuel.

 

Regardless of what suitable container you choose to mix your fuel in, it's important to make sure it is free from dust, dirt and other contaminants, as dirty fuel can cause engine damage and poor performance. 

And there you have it! Mixing up 2-stroke fuel for your large-scale RC car is a breeze. Just remember to use high-quality products, follow the correct ratios, and you'll be ready to tear up the tracks.
