Does anyone drain also the oil radiator when changing the oil?
If yes any tips for me?

Mazda say that the oil quantity for the oil change is about 3.5 liters and 3.8 Liters with the oil filter. But say also that the total engine oil is 5.6 Liters. It's mean that when we change the oil we still have about 2 liters of old oil.

Thanks

 

 

Pop off an oil cooler line and you may get another 1/2 qt out. Personally I don't feel its worth it.

 

yea what ihor said,

not worth it

change your oil very frequently and it won't matter. Hell, i don't even change the filter, as i change the oil every few hours or run time or less

 

Doing proper oil changes every 3000 miles with a decent oil and filter is really all you need. Doing something exotic won't do anything special for your motor.

I think your situation is a little different than the rest of us lol

 

 

Sludge is an indication of either poor quality oil, overheating of the oil, or not changing the oil frequently.
A good synthetic oil can solve that problem. Idemitsu!

 

None of that, but thanks.

 

Thanks to evrebody,
I use Royal Purple 10W40 and OEM oil filter. change oil less than 3000km (2000 miles or something)
The problem is that I don't use often the car, so the oil sometimes is old, not used.
