How to Mix the Oil to Gas Ratio for an Echo Chainsaw

Echo manufactures a variety of products and tools, including chainsaws, blowers and weed eaters. Using the proper fuels and fuel ratios help them to operate properly. You can purchase premixed versions, like the Red Armor fuel 50:1 premium mix, or products designed specifically for the brand, like Echo SRM 225 oil. Before buying anything, it's wise to check the manual to see what the company recommends for each tool.

Echo chainsaws have two-stroke, air-cooled engines that require a mix of unleaded gasoline and two-stroke motor oil with a ratio of 50:1. To determine the Echo two-cycle oil mix ratio, you can search for an online 50 to 1 fuel mix calculator. These calculators are simple to use. Enter the number of liters in the first box and the gas/oil mixture in the second and click "calculate."

Another option is to use a simple equation. For the 50:1 gas to oil ratio, use 2.6 ounces of oil for every gallon of gas. Echo power blend two-stroke oil 1 gallon is best for its brand of chainsaws. Your manual will show you how much gas it needs to run. To mix the fuel, pour the two-stroke oil into a clean gas can and then add the right amount of gasoline. Close the lid and carefully mix it. Be sure to use it within 30 days or add some stabilizer to extend its shelf life.

Echo weed eaters (also called trimmers and brush cutters) need a mix of gas and oil to run. As an example, the ratio for the SRM-3001 is 32:1 regular leaded gas/oil. Echo has 20 different weed eaters shown on its website, so you need to be sure to read the instructions to verify the proper ratio for your model. You should never mix it directly inside the engine's fuel tank when you're mixing gas and oil. You should always use a gas can for mixing purposes.

The company website also has 16 hand-held and backpack blowers from which to choose, and almost all of them are gas-powered. The PB-265LN power blower uses a 50:1 ratio, and Echo recommends using 89 octane gasoline with Echo Power Blend X TM Universal 2-Stroke Oil. If you read the ES-250 manual, you'll notice that this model also requires the same fuel mixture.

Fuel is highly flammable, so you'll want to take the proper safety precautions whenever you're working with gasoline and oil. Always mix them in a separate gas can instead of right in the engine. Choose a leakproof can that's designed for this purpose; it should be clean and slightly larger than the amount of fuel you need to mix. You will want to start by measuring the oil and then pouring it in first. After that, you can measure the gasoline and then add it, finishing by sealing the can securely.

Instead of shaking the can, swirl it around in circles for about 30 seconds. Remove the cap and look inside to see if it is well blended with no dark or light streaks. When you're sure that it's uniformly mixed, proceed with filling the tank. You should try not to mix more than you need because it's better not to have too much of it sitting around. If the mixture uses too much oil, the engine could start to leak or smoke. Be careful, though, because if you don't use enough, the extra oil may damage or destroy it.
