There room a few types of gas you can use for her gas weed eater, but don’t forget to inspect the one typical for the design you have. Also, protect against cheap gas because it can be fatal because that the engine in the lengthy run.

Some world prefer going premium but, in general, mid-grade unleaded gasis usually the ingredient of choice. Because you will mix it v oil, the shortest recommended octane rating for petrol you must use is absolutely 89.

The reason for this selection is the reality that fuel v a reduced octane rating will probably increase the temperature of your unit’s engine also much. The elevated engine temperature will reason piston failure and consequently feasible damage come the engine.

Many manufacturers stamp the encourage fuel/oil ratio for each specific weed eater there. If girlfriend can’t find it, look at for that data in the owner’s manual.

There room three feasible ratios (32:1, 40:1, and also 50:1). Determining the appropriate one for her unit is a critical thing. If you usage the wrong ratio, you space at hazard of harming the engine.

Basically, that is no too difficult to calculation it. The most common fuel/oil mix proportion is 40:1. That method that you require 40 components of gas come one gallon of oil. The exact same rule uses to the various other two mixtures.

If you know that one gallon the oil is same to 128 oz. (1 us gallon), you just need to divide 128 oz. With the encourage mix ratio and also you will certainly calculate how numerous ounces the oil friend need. It deserve to be:

2 – 128/40 = 3.2 oz. That oil

That way you will need 3.2 ounces that oil once the recommended proportion is 40:1.

3 – 128/50 = 2.6 oz. That oil

That means you will require 2.6 ounces the oil as soon as the recommended ratio is 50:1.

You deserve to make the calculation because that liters together well, or just look at the table ns enclosed bellow.

*128 oz = 1 united state gallon

As I currently mentioned, always choose at least 89 octane’s gas through a preferably of 10% alcohol and also oil sufficient for two-cycle engines. Since automobile motor oil consists of non-combustible additive which can damage the engine that the weed eater, you have to avoid using it.

To mix gas and also oil properly, to water oil into the fuel canister first. Then include the encourage amount of gas. After ~ closing the canister, shower it to ensure the gas and also oil are blended correctly. Be cautious while act it. I am pretty sure that friend don’t want to have actually the mixture everywhere the place.
