confused about engine oil specs for diesel engine
 

Hello all,

I just bought this 2000 V40 1.9D (D4192T2 engine) with 300 000 km to be used as a sort of a beater car for daily commuting. It has cosmetic issues (peeling paint, some hail damage) which I don't care about, but is mechanically in good shape (checked by a mechanic) with working AC and cruise control. It was cheap too, 280 euros.

Anyway, I want to keep it regularly serviced so I was looking at the engine oil specs and I'm a bit confused.

Ambient temperature range throughout the year where I live is approx. from -15C to +35C with a couple of days even higher and lower.

The owner's manual lists these viscosities for different temperatures:

+10C and below: 5w-40
-20C to +30C: 10w-40
-15C and above: 15w-40

It also gives a separate warning not to use 5w-40 above +10C.

While VIDA says to use 5w-40 regardless of ambient temperature.

I don't want to change oil more than once a year because I won't be doing more than 15k km a year.

Which viscosity oil should I use? I know the rating has to be ACEA A3/B3/B4.

Thanks

5w40.
Its a Renault engine, renault spec 5w40 A3/B4 (10w40 if 5w40 not available).
I think the book has a typo or youve misinterpreted it, of course you can use 5w40 above 10°c, all 3 oils are 40 when hot, so just the same at operating temp.
The difference comes when cold, 5w is the best of all 3 for cold starts, 15w would be inappropriate unless vehicle is used in the sahara.

Thanks, I'll use 5w-40.

Just to clarify the source of my dilemma, here's what the book says:
