oil change — Toyota Celica, 1.8 liter, 2003
today I changed the oil, it was very dirty, even washing in 10 minutes became black black)
I suspect that the mark in the service book about maintenance at 37,000 km was the last oil change)
It felt like the car immediately began to gain momentum briskly)
Issue price: 2,300 ₽ Mileage: 56,000 km
It's a good thing)))) now a new life has begun)) I recommend changing all the liquids to fresh ones over time.)))
Of course, I would not advise washing to do ... "flushing oil". After all, the cheapest oil, the worst quality) remains. and even 15 minutes of engine operation in such oil is highly undesirable, especially when it comes to the capricious ZZ series.
Any oil has detergent properties. If you love your car and have an extra 2 thousand rubles, it’s better to drain someone else’s, fill in the one you want, naturally replace the filter, drive 500-1000 km. and change the oil a second time with a filter change ...
But this is just my opinion))
+ a million as they say, in addition to being stupid, you also expose the engine to an extra 40-60 seconds of oil starvation until the air plug pushes out the remnants and the flush enters the channels, and it became black not because of a dirty engine, but stupidly scooped up emulsions from an old filter...
