Dealer put in wrong oil?

[fafafooey]

Curious what you guys think. I have a 2009 Infiniti FX35 with the VQ35HR engine. Same engine as the Nissan 350Z and Infiniti G35 of that year.
Infiniti calls for 5w-30 and I just noticed the dealer put in M1 0w-40 today according to my receipt.

Should I be concerned? Interestingly, I have noticed some folks here using the 0W-40 with this engine and liking it. I suppose I should be fine. Maybe they did me a favor?

I wouldn't worry

Sounds like the service manager is a BITOGer

Better oil than the manual calls for. You could, I suppose, demand 5W-30 but it would be a downgrade. Get some sleep, nothing to worry about.

VQ engines are notorious for being tough on their oil, don't worry one bit.

Exactly!
Many Nissan/Infinity engines enjoy a nice drink of 0W40. The dealer did you a favor!

So much for following.........never mind. The dealer did you a favor.

This, 0W40 is a great choice.

Don't worry. It'll be a 30 weight right about - you've driven the car, right? - now!

Problem solved

I've put about 60k trouble-free miles on my VQ35HR Infiniti using M1 0w-40 every change. I had a UOA early on that showed everything was fine.

Char Baby and FordCapriDriver are spot on here. Mobil 0w40 is a big upgrade here... Meets MB 229.5 and Porsche A40..

I agree - - - the dealer must really like you!

BINGO!

 

[Garak]

Yes, it'll be fine. Everyone here must have collectively fallen out of their chairs, with a dealer putting in something more robust than specified, rather than the cheapest bulk they had available.

0w40 is great

 

[nyumski]

it will eventually 5w30 so dont worry, my friend here using 0w40 in his nissan z

 

[JimPghPA]

Because it is a 0W it will have cold flow that is better than a 5W, and because it is a 40 weight it will protect better than a 30 weight when it gets hot.

In other words 0W-40 is better than 5W-30.

I havn't really been keeping up with the trends.

Did "Follow the manufacturer's recommendations" go out of style?

How liberating.
