Hi, I have Passo 2013 imported in 2014. I am using Zic A+ 5W-20 engine oil and changing after 4500-5000 kms
now i want to change the oil as i heard standard of Zic oil is going down because of local production.
so any suggestions which oil should i use now?
what about liqui moly, shell and caltex? which one and why?
will it be ok to start using 10W-30 if 5W-20 is not available in some other brand?
also suggestions for oil and air filter. (please no "Use genuine Toyota parts" remarks, there is much more variety and better quality available in other brands in same price range)
