Which Oil? 0-40 or 5-30

[kitsrider]

My local Auto parts store has Mobil 1 on sale starting Friday.
5w30 or 0w40 for my e53 3.0 2003
Thanks

What does it recommend in your owners manual?

This is what it says in mine for the 4.4 V8 N62:



But I've used both 5w30 & 0w40...I'm not sure why either would really make that big of a difference if you change your oil on a regular basis. Both viscosities work in all ambient temps as mentioned in the manual.

This is what I bought the last time:

Perfect
Thank you!

You don't say where in BC you are, but 5-30 flows down to -40, and is perfectly ok down to -30, the coldest I've used it in. If Kits means Kitsilano, that is more than enough. On the other hand, if you are in Dease Lake....

Good work......... Yes Kits is correct, but have since moved to Parksville.
Cheers.

I use 5w-40 personally in Jersey.

prob in Canada I would do 5w-30 all year round

Interesting timing of this post was going to ask the same question but hesitated as oil threads on some other sites (cough m5 cough) are not well received.

Reviewing Mobil's site they recommend 0w 40 for my 4.6is and was going to ask the same question but seems it has been answered. Thanks OP

+1 on 5w40 here

My 3.0 runs well on 0w-40 Mobile and since it's only around $23 per 5 QT jug down at the local Wally World its also wallet friendly, especially considering I burn about a 1/2 QT every 1,000 miles.

I've been running the Mobil[1] 0-40 for the last 85k of the 185k total miles on the M62 4.4.

OE TC guides, near zero oil burn (drops about 1/8" between changes at 60% SII), even towing in 120 deg F stop/go traffic.
