How much oil should you put in a Stihl chainsaw/mower? Learn the answer from the experts!

Many of our customers ask us, online, over the phone or in person, questions like "How much oil should be put in the chainsaw's gasoline?" or "How much oil is put in gasoline for a Stihl chainsaw?". Since this kind of confusion is repeated, we decided to write an article on this topic to offer answers.

First, we must clarify that in order to function properly, the machines listed above need a fuel mixture consisting of gasoline and a special engine oil (also called additive or mixture), in different proportions. Even if the ratio is clearly in favor of gasoline, as you will see below, the addition of oil should not be neglected in order to avoid accidents and obtain the desired results.

The answer to the question "How much oil should be put in chainsaw gasoline?" is variable because it depends on each brand, even each individual product. Generally, however, standard ratios are 50:1 (one part oil to 50 parts gasoline), 40:1, or 25:1.

To the question "How much oil should be put in the chainsaw Stihl?", the answer is given by the German manufacturer himself, on his website. So for two-stroke engine equipment the ratio is 50:1. "The quality of the two components (gasoline and oil) is crucial for the operation and life of the engine. Inappropriate fuels or mixing ratios that deviate from the norm can lead to serious damage," says the German brand.

Here's how some of the most common oil-to-gasoline ratios "translate" for both chainsaws and chainsaws:

Ratio 25:1 - 1 l gasoline+40 ml oil / 2 l gasoline+80 ml oil / 3 l gasoline+120 ml oil / 4 l gasoline+160 ml oil / 5 l gasoline+200 ml oil;

Ratio 40:1 - 1 L gasoline+25 ml oil / 2 L gasoline+50 ml oil / 3 L gasoline+75 ml oil / 4 L gasoline+100 ml oil / 5 L gasoline+125 ml oil;

Ratio 50:1 - 1 L petrol + 20 ml oil / 2 L petrol + 40 ml oil / 3 L petrol + 80 ml oil / 4 L petrol + 100 ml oil / 5 L petrol + 120 ml oil.

As you know, Roco Piese online store is always there for its customers, having an extremely rich and varied offer, only with quality and especially useful products, at low prices. This category also includes the gasoline and oil mixture box, which you can find available for no more, no less than 18 lei. With its help, you will easily mix the two components of the fuel, guided by the graduations (gasoline to the mark, then oil to the mark corresponding to the ratio - 50/1, 40/1, 32/1 or 25 /1).

Precautions. Finally, we emphasize again the fact that the oil intended for the fuel mixture for chainsaws and chainsaws is special and it is not worth compromising on quality for insignificant savings. This is all the more so in the case of using oil that does not meet the requirements, there is a very high risk of equipment damage, which will lead to much higher additional costs.
