I have bought it before, very good, but next time I will get the other one from the same company, the XP, which is fully synthetic

I bought the Efco ds 5400t in March 2025, and I also had the Jonsered Gr41, to which I had recently changed the cylinder-piston, not the original one (the original costs 288 euros)... and I decided to get quality oils. I chose ls Husqvarna for the Jonsered Gr41 and xp Husqvarna for the Efco 5400t... (for the Jonsered Gr41, every 4-5 tanks with ls Husqvarna, I use fuel with xp Husqvarna). I use the brushcutters professionally, plus my own olive groves... they opened the Efco at the dealership, everything inside was shiny... like new... I opened the Jonsered Gr41 with a friend... everything inside was spotless... in the end, the oil, especially the XP Husqvarna, may be expensive, but you work with safety...

I have been using it for years in all my machines. Minimal smoke during operation.
I haven't opened any to see the engine internally, as I haven't faced any problems so far. If that means anything, the pistons appear to be spotless when viewed through the spark plug hole.

Without having knowledge in the field, I get the impression that my lawn mower works very smoothly with this oil and without any particular smoke or smell

It's worth its price and then some; I just don't understand how it can increase by 4-5€ a month from when I bought it last time, which was a month ago

The best with the right proportions.
500ml gasoline, 12ml oil.
With a syringe, it's the best application.
Always mix just before use!!!

Husqvarna quality. Good lubrication, the engine runs smoothly and without smoke or strange smells. Personally, I wouldn't risk using another/cheaper oil as the slightly increased cost is offset by the trouble-free operation of the brush cutter.

Excellent performance in Husqvarna lawnmower and chainsaw for 8 years. Smooth operation, zero failures, perfect combustion, zero smoke

Amazing oil, excellent engine performance, reduced emissions! Also, LS is excellent too!

Very good oil especially for its price. I am now on the 4th liter and I use it on a Nakayama lawnmower and chainsaw. I mix it with a little castor oil in a ratio of 80/20 and I put 40:1 in the gasoline. It doesn't smoke at all and its smell is not very strong. I don't see any residue on the spark plugs, I haven't solved the engine yet since they still work perfectly.

Although the price is a bit steep, I bought it without much thought for the protection of the Husqvarna trimmer's engine that I bought this year.

The smart dual nozzle system is convenient so that you don't have to measure with syringes. This system may seem unfamiliar the first time you see it, but ultimately it serves well in terms of usability.

By far the best oil out there, hands down! I've been using it for years on my tools with heavy use. Even if it had 10 stars, I would give it to them!

I have been using it for years on various machines that work hard, and they haven't given me any problems!
The price is a bit steep though!

I used both anonymous and branded oils and constantly faced issues with my tools (chainsaw, lawnmower). From the moment I started using this specific one, I forgot what damage means.

I have been using it for a year on a Chinese lawnmower and a Chinese chainsaw. It doesn't produce much smoke, almost none, and it seems to do a good job on the cylinder and piston.

It produced some black marks at the beginning but I had a ratio of 1:25. They told me to use a ratio of 1:45. Everything is fine. The machine is harvesting. I would recommend using a syringe for more accurate ratio. Very satisfied with the oil.

Very good oil, it doesn't smoke at all, the chainsaw and spark plug are spotless, worth it and more!
