Hi Every one,
I have just bought a new Suzuki Cultus 2006 (1000 cc Carborated Engine). It has done 3,500 Kms yet and I have to go for an Oil change. I just cant decide which Oil will be best for my car ?
I have the following Oils under consideration:
Zic XQ (5W 40) (Fully Synthetic)
Zic A (5W 40) (Semi Synthetic)
Castrol GTX Magnetic (10W 40)
Caltex Havoline Formula (25W 50)
Shell Helix Plus (10W 40) (Semi Synthetic)
Please let me know ehich Oil is best and how much milage should these oils give with normal drive within the city ?
The owner's manual of Zultus recommends (10W 40) or (25W 50) oils. Would it be harmful if I use an Oil with specifications lower than (10W 40) e.g. (5W 40) ???
Since all the Synthetic Oils usually have lower viscosity Index. And is it safe to use Synthetic Oils in these old technology Engines?
Please comment only if you are an expert, since I seek for an expert's advice.
