Hi.

I have a Audi A4 1.9TDi avant quattro with a 115HK PD (ATJ) engine.

The sticker on the engine hood says I should use 505.01 oil. But the car's "user manual" says I can use both 505.01 and 506.01 oil.

I drive in Norway, where there is a lot of snow in the winter. Normally gets down to approx. -10 to -20°C during the winter. And might get as low as -30° or lower, but this is more rarely.

In the summer there might be hot, about +20 to 30°C.

What would you recommend to use ?

If I go for the 505.01 oil, it's 5W-30.
I I go for the 506.01 oil, it's 0W-40

Actually I used 506.01 during the last oil change. Should I continue with this oil, or would you recommend to go back to 505.01 (which will be 5W-30. I use Shell oil).

Howdy, are you certain about your viscosity choices? Most 505.01 oils are 5w40. I've only seen 506.01 in 0W30. Perhaps you will double-check.

It sounds like the 506.01 might be a benefit to you. There are no issues running it during "hot" weather.

Sorry, a typo.

The 505.01 is 5W-30.
But the 506.01 is 0W-30 (not 0W-40).

I don't think you are going wrong with either, but considering there is a weight difference the 0W30 would be a little better in winter.

Thanks.

I'm then going to continue with the 506.01 oil :)
