I went for an oil change, I drive a 2018 Toyota Yaris, I maintain regular oil changes and I was told I need an engine flush (23000 km on car) and I agreed because I want to keep my car maintained for warranty purposes as well I had the cabin filter changed in September and even though they did not look at or mention it this time the put on my invoice that they looked at it and it was dirty and they advised me which is a blatant lie and on the sticker they gave me it says I am due for another oil change July 27. I called another mechanic this am and was told the engine flush was nothing but a money flush, I also had my engine filter changed again- this is the second time they changed it and now I am wondering if even that was necessary.
