Oil - 15w40. 10w40? What to use?

[Ryan]

The book for my Megane says I need to use 15w40 oil, question is can I use 10w40? I need to change it before I sell it...

 

[jonny_g]

yes you can

yeah the lower the first number the better it is for cold weather, the first number describes the oils viscosity at 0degC the lower the number the thinner it is IIRC


the 40 is the oils viscosity at 100degC, the higher the number the thicker it is

you can use any of the following, 0W40, 5W40, 10W40, 15W40

I have sold the car but need to change the oil before the guy collects so the 10w40 is all good
