Take care with Stihl 4 mix engines to avoid a costly mistake! I have used Stihl products all my working life, which is around 40 years. I have to say that over the years, having owned Stihl chainsaws, Stihl strimmers, Stihl hedgecutter’s Stihl blower’s and even a power washer. I have also owned and used many Stihl 4 mix engines. I have had very few problems, I guess that’s why I keep purchasing Stihl products!
However, Taryl explains in detail about a problem in some Stihl 4 mix products. It appears that the issue is with some of the backpack blowers. Starting with the BR500, 550, 600, 700 and 800 models.
It appears that Stihl are using a bronze bush rather than a needle bearing on the above models. It does make you wonder why a company like Stihl are doing this. However, I have a BR 600 backpack blower that is almost 7 years old and is used regularly and commercially. Thankfully, I have had no problems so far!
Use The Correct Oil
Unfortunately, there are some cheap oils on the market. It’s important to remember that a 2-stroke engine relies on the fuel mix to lubricate the engine. Also, the four mix engines run quite hot, so it’s important that they have good-quality oil.
The good news is that if you use the correct Stihl oil, you shouldn’t have any problem with your Stihl 4 mix engines. When it comes to engines and you have a quality machine, there’s no point in taking shortcuts. As I mentioned above, I certainly haven’t had any problems with my Stihl BR600 backpack blower, in almost seven years. So the moral of the story is don’t take shortcuts and use the correct oil.
