I can recall an era when Hyundai people used to recommend Mobil or whatever spelling it is then they started recommending Zic and so on.
Off course they recommend only those engine oils where they can see good margin.
I use ZIC A+ oil in my santro, recently i change the oil and this time use Caltex shell hilux Plus , After using this my santro start droping water from car exhaust pipe , i know it is good sign of engine health
What u say "Caltex shell hilux Plus " is good oil
Dude it doesn't make sense to me. You said by changing engine oil your car started dropping water from exhaust pipe.... I think you didn't notice it before, It should have been like this on Zic A+ too. Furthermore its cold weather these days so its very common, even you'll see dropping water from exhaust on very weak engines these days.
