The best type of string to use for a Kobalt weed eater is a high-quality, durable trimmer line that is compatible with the specific model of the weed eater.

Using SAE 5W-20 oil in a weed eater is not recommended, as most weed eaters require a specific two-stroke oil mixed with gasoline for proper lubrication. Using automotive oil, like SAE 5W-20, can lead to improper combustion, increased wear, and potential damage to the engine. Always consult the manufacturer's guidelines for the appropriate type of oil to use in your equipment.
For an Echo weed eater, it's recommended to use a high-quality 2-stroke engine oil that meets the ISO-L-EGD and JASO FD standards. Echo specifically suggests using their own brand of 2-stroke oil for optimal performance. Always mix the oil with fresh gasoline in the correct ratio, typically 50:1 (2.6 ounces of oil per gallon of gasoline), unless specified otherwise in the user manual.
It depends on the brand of trimmer you bought. Stihl, Echo, Husqvarna use 50:1, or 1 gallon of GAS to 2.6oz of 2-stroke oil Weed Eater, Poulan, and Poulan Pro use 40:1, or 1 gallon of GAS to 3.2oz of 2-stroke oil Ryobi's use 32:1, or 1 gallon of GAS to 4oz of 2-stroke oil
