I am not a geek at oil so went for what mechanic told me, he said that Havoline 20w50 is good for engines that reduce oil , plus a friend of mine is using the same oil in his santro club 2004 and civic 2001
As far as the API is concerned suzuki still uses 2002 printed car owner manual for mehran and that manual suggest the grade to be SE,SF or SG
As far as going back to zic is concerned i can't take a risk now coz i already have switched 3 brands , specially the later too pretty quickly with a gap of just 3800km so now going for another one will ruin it up
it will be like semi synthetic, semi synthetic, mineral and then again somewhat semi synthetic
