![]() ![]() Runtime is a bit easier to measure because manufacturers typically provide the fuel-tank size and the maximum runtime on a single tank of fuel. However, a gas string trimmer with a four-cycle engine will usually be more efficient than a trimmer with a two-cycle engine. Fuel Efficiency and Runtimeįuel efficiency can be difficult to gauge, as there are a number of different factors that can influence it, including fuel mixture, ambient temperature, operating speed, and even the type of grass or weeds being cut. So if high power is the goal, look for a product with an engine larger than 40cc. When displacement is low, power output is also low. This is because a larger engine is generally capable of displacing more air and fuel at one time. As an engine increases in size, as indicated by the cc, the power output of the engine increases. This is measured in cubic centimeters (cc). The size of the engine is another important factor. However, products with four-cycle engines typically cost more and require regular oil changes to keep them working properly. These tools also are more powerful than products with two-cycle engines, making them a good choice for yards that are more than an acre. The efficiency comes at the cost of size and weight, so users should expect a heavier tool when they pick up a four-cycle engine trimmer. ![]() Four-cycle engines are generally considered more efficient than two-cycle engines.Though lower maintenance, these trimmers have less power output than those with a four-cycle engine. ![]() Two-cycle engines use a fuel-and-oil blend, which reduces average maintenance to changing the weed-eater string and emptying the fuel tank before storing the trimmer for the off-season.
