i've never been able to get a clear answer - can someone recommend a weight for winter use? i use the oe weight currently. amsoil 5w30. i'm in seattle...it gets around 32 degrees but we're expecting colder climates.

thoughts?

thanks guys,
eric

Don't use a different oil because it's colder outside. There's no reason to. Just stick with the 5w-30.

It's all in the owners manual, infiniti recommends specific oil weights for certain temperature ranges.... and it looks like they say 5w30 for any given temp...LOL!!

Yep, the W in your oil weight stands for "winter" so you're covered 5W-30

Opposite extreme here, but about all I would change is run a 10W-30 in a Dallas summer, June-Sept. But as mikelr, stick to the "book" and you can't go wrong.

I'd run a 0W-30 in freezing conditions.

I'd run a 5W-30 and keep my warranty intact.

Thats what i use... year round,,, but especially for the high rev up on a cold start,, want that " 0 " in front of the 30

bleu ardoise

You won't lose any warranty fact is 0W-30 is much better for your engine when cold starting... I have the dealer pour in Amsoil SSO 0W-30 every oil change...

Wouldn't you "theoretically" have more residual oil sticking to the parts w/ a heavier oil so you'd have better protection at startup? Just curious

bleu ardoise

No actually at start-up oil is already way too thick.

Okay wow, I read the whole thing, there goes an hour! Great info!

So should we all be running run synthetic 0W-30 in our G's? I'm a 5W-30 PU fan myself.

bleu ardoise

Yes and PU is a great oil same with PP. That forum is a great community and reference site for all things oil.

that was a great read - albeit i skimmed through it (i have a midterm tomorrow ). i've heard the same saying around from time to time. never really knew what to believe. what about on longer drives though? my gearing revs me a tad bit higher than the average g w/ 3.69's (~300 rpms higher). hm...
