That's all I have ever used but should i keep using it in the hot parts of the year down here? |
If anything the 0w-40 will be more efficient than the 0w-30 in warmer weather. Keep in mind the 'W' in multi-viscosity oils stand for Winter grade oil (or cold start viscosity) and is not a direct representation of weight, even though the term is misused very commonly. The last number set is high-temperature viscosity and represents how easily an oil pours at higher temperatures. Viscosity is rated on a scaled of 0 to 50, 0 being easier to pour, where 50 doesn't pour as easily, with a more honey like characteristic.
That said, I run 0w-40 Mobil 1 year-round.
