I recently bought a ford mondeo tournament 2,0i bj 99 and it’s following engine oil in Castrol GTX A1 TOPUP 5W-30 is this engine oil recommended? would castrol 0w-40better? or can someone recommend me a better one Besides, I wanted to know if it’s true that by a ceramic motor coating the fuel consumption is reduced and that the motor is running quieter and that the lifespan is longer, since it is supposed to reduce friction like for example ceramic power liquidhttp://w ww.qvc.de/…/frameset.asp?…
