I own Honda City ivtec 2012 its 30k on odo, engine is in perfect condition, no oil leakages, no oil reduction, etc every thing is perfect. also m using CNG since 1 year and each and every thing is fine. I m using ZIC A+ and it is 5w20 grade, now due to summer i feels it is not suitable on high temperatures, experts plz guide me should i go to Zic XQ 5w40 (Seems to me suitable for both winter and summer) or should i go for ZIC A 10w40 ?
I dont want to waste my money as well as dont want to ruin my car by using Honda Oil..
Thanks in Advance.
And what about changing from mineral oil to synthetic? I just changed from havoline 10w-30 to havoline 5w-40. didnt flush the engine.
Flushing the engine changing from mineral to synthetic are just myths!..If ur engine has had timely oil changes before then u dont need to flush ur engine neither using synthetic engine oil cause leaks..
