A friend of mine, his father is preaching for me to run 0W30 over 5W30 in my 2013 Silverado.

The manual calls for 5W30, but GM is now recommending 0W20 in the new 2014 5.3L engine.

Many folks are calling 0W30 the new 5W30.

I would gather that 0W30 would have slightly better cold starting properties than 5W30.

Any thoughts?

I too have been thinking of going with a 0-30 in my Trailblazer for the very same reasons as you. I was told that TN winters aren't cold enough to HAVE to switch to a 0-30, but that it also wouldn't hurt anything. I'm sure your winters are much worse than ours in TN are, so I wouldn't see why an oil with better cold flow properties wouldn't be the way to go for you. I hate the way my engine sounds in the winters with a cold start.

There should be no harm in running a 0W-30, but not much in the way of benefits in St. Louis. It's not like it gets really cold there and you therefore need to make use of the better uber-cold flow properties at startup.

A better flowing oil is always better though isn't it?

Not really. lUBRICANTYS ARE chosen with a viscosity range to give good service life to the machinery as designed and its operating environment.
Some thin oils will sacrifice lubricity for cold flowability. There are tradeoffs as in most anything.

So does ExxonMobil.

Isn't this about the 8,000,000th time this question was asked?

True, GM does allow the user to use 0W30 in extreme cold temperatures.

Here is an excerpt form the owners manual.

Quote:

Cold Temperature Operation: In an area of extreme cold, where the temperature falls below 29C(-20F), an SAE 0W-30 oil may be used. An oil of this viscosity grade will provide easier cold starting for the engine at extremely low temperatures.

Hope the 0w30 is Dexos approved.

Why do you "hope"? If it is M1 AFE 0W-30 then it is, per ExxonMobil's website.

Yes Mobil 1 has the following dexos licensed weights:

0W20, 0W30, 5W20, 5W30, 5W20EP, 5W30EP

Mobil 1 has the bases covered.

In theory, the difference in lubricity would be negligible though. The 0W is just rated for pumpability at a lower temperature than the 5W.

+1 0w30 in a 5w30 application if cold starts are expected, but wouldn't wait for -29C, -5 to -10C will do.
