Hi, I bought RS turbo 2020 model, very next day i went to honda point for its complete check up. Mobil Oil was not good. Seems like very blackish, so changed the engine oil to Ow 20 SN recommended by honda for turbo cars. After 600 km driven, oil again change to black from bottom of the oil guage and car feel like heavier, within 500km its was very smooth.
Should i change the oil again? with engine flush ?
My car driven 600km after oil change, kindly suggest engine oil Mobil1 or Amsoil 0w 20.
Previously i have honda vezel and used mobil1 0w 20 (recommended millage on this oil is 10000km)
