15w40 is recommended by LR!
But:
The smaller the first number, the better the oil will flow when you switch on your engine. Thin, low viscosity oils flow easier to protect engine parts at cold temperatures. The faster oil flows to critical parts of the engine, the more protected they are from wear.
So a 5W-30 will flow easier than a 10W-30 at start-up temperatures. And a 10W-30 will flow easier than a 15W-40 at normal engine operating temperatures.
What’s more, lower viscosity oils can reduce your fuel costs and emissions.
No matter what you put your engine through, you need to know your oil will protect your engine under all conditions. And the right quality oil matters

Td4 engine, use oil meeting ACEA A3/B3 specifications, and having a viscosity band recommended for the temperature range of your locality. Where oils to these European specifications are not available, well known brands of oils meeting API SH quality should be used
The oil will not affect your emissions
