Is a 1:50 Fuel Mix Suitable for the Demon RQ580 Brushcutter?

Hello, I would like to ask if if it pours such a mixture is it good or not?
Please reply.

The manufacturer will answer all your questions in its manual

Stick to the manufacturer's recommendations. In the instructions, you have written what oil to use, what mixture composition and what gasoline to use. You can't do it because you will damage your engine. One requires 1:30 second 1:40 third producer 1:50.

Everyone says 1:25. https://www.youtube.com/watch?v=VzisR9CagRI

Oh, I have to change

Hello
As for the mixture, everything also depends on oil but also on fuel.
It is known that this is not a racing engine

It is recommended to use such proportions as recommended by the manufacturer.

And here you will be surprised.
I have such a scythe 1:25 and the mower after 3 months of use has such carbon deposits on the Candle that the engine stopped screwing at full speed, after cleaning the carbon it returned to normal.
The neighbor also has two no name items, and each one goes on 1:50 carbon zero, the engines are still running today, I think lac 1:25 (for one two mowing) when new and then 1:50 good stihl oil e.g.
pour only one oil and it will be ok
Unless you want to remove the cylinder 2 times a year to clean the carbon deposit. Regards.

Stihl oil, husqvarna and similar half 1:50. Other rubbish 1:25. From experience. In addition, the basic property of this oil is not the formation of carbon deposits.

The amount of carbon deposits depends on the quality of the oil. Stihla oil is not so good (the cheapest red is mentioned).
The 1:25 mix is terribly rich for 95/98 octane gasoline.

His scythe (fs350) has been using the motul 710 for several seasons. The scythe works as it should, zero carbon and the oil price is lower than Stihl oil.

In general, if oil is taken care of, candle filters and service, then even Chinese people will work for a long time. The most important thing is not to pour the cheapest oil and change even the candles every season, and clean the filter from time to time



best regards

Candles change every season is a slight exaggeration, unless it is Chinese crap. I have been able to stand for 15 years in Stihlu and I have been working on Stiga since 2002. I have an older mower, a smaller one, and the candle was not replaced. But they are all corporate. Briggs engines.

Added after 4 [minutes]:

A 1:25 mix was used for WSKi lux oil with gasoline. After him it was nagaru everywhere even the muffler was clogged. Then they invented the mixol. 1:30. It was a bit better.

I am talking about regular candle changes, because you never know when they will fall apart, and the cost of PLN 10 with annual use is not a property: p

As a matter of fact, good oil is the basis. Currently, there are even oils that can be mixed in a ratio of 1: 100.
Mixture 1:25 I was only doing it to a super card but there was 130 octane fuel.


Often also in cheap scythes / pilas you can find a strainer that causes a lot of problems. Then it is worth lubricating the filter with oil so that it does not run.

The above recommendations apply to all saws / scythes that we service together with a colleague for forest use.
An interesting fact is that one of the stihla blackbirds has never undergone renovation despite being 25 years old, and the only thing that has been done in it is regular services.

It's a simple path to replace with a new scythe.

From many years of experience with these scythes, you can pour Husqvarna blue oil 100ml / 3l of gasoline.

I don't know why you are assuming a topic, you have everything described in the instructions.
Husqvarna blue oil is the only one that does not make carbon deposits and does not soak, and is relatively cheap for a professional 2 stroke about PLN 40 / 1l.
