engine oil

[Cider]

suzuki vitara 1999, due engine oil change, which should i use, 10w 40, or 15w 40, not fuel injection..any one know?

depends on what engine you have,check in your handbook,it will tell you in there what to use.

I would go 10/40 as there will be no difference when it's hot
but the oil will be thinner when it's cold, and will get round the engine quicker, also most engine wear takes place when the engine is cold, so it should benifit from this.
