I have a question, or rather a series of questions for anyone who feels like answering.

I own a 2010 Nissan Versa with the MR18DE and 4 speed automatic transmission(not CVT) with about 56k miles on the odometer. My daily commute is only about 5-10 miles usually only getting the water up to temperature. 70% of my driving is in town, stop and go traffic, at speeds around 25-35MPH. The rest is short distance driving on the highway at 50MPH. Summer temperatures hover around 98*F and can get up to 110. Winter temps hover around 40*F and dip below 0*F. It's very windy, dry, and dusty during the summer.

My owners manual calls for SAE 5w-30. Previously I had the dealership change the oil every 4k miles since they were running a special for a nine dollar oil change. Which amounted to a cheap generic filter and what was supposedly "Mobil 1 synthetic blend". I recently changed my oil with Mobil 1 extended performance 5w-30 with a Mobil 1 filter. Already I've noticed a slight bump(1-2 MPG) in mileage and a significant reduction of lifter noise. Right now I'm just planning on changing the oil and filter every 6 months.

My question I suppose is if I would see any benefit switching from 5w-30 Mobil 1 Extended performance to 0w-30 Mobil 1 Advanced Fuel Economy? Or is there another brand of oil and filter that you guy's would recommend over Mobil 1?

Thank you for your time. I'm still trying to educate myself about the properties of oil and car maintenance in general. It's a bit more complicated than I previously thought.

You are doing a short OCI with synthetic and so why not save $3 at Walmart and get the 0W-20 stuff. We get much hotter here and I run 0W-20 in both of my vehicles, which usually do a yearly OCI.

The M1 AFE might be a tiny bit cheaper, and you may see a fuel economy bump, but that's just as likely to be buried in the noise of normal driving variations. On the positive side, XOM will stand behind the use of their 0w-30 in that 5w-30 application.

Wont hurt a thing to run 0w30 where 5w30 is called for. Thats what I did in our Uplander, however, it makes a lot more noise now. Thats probably just because of the Mobil product in general.

First number is lubricity when cold, how well it flows when cold.

Second number is lubricity when hot...

Hence if 5W-30 is called for, you can use 10W-30 in the summer, and 0W-30 in the winter...

Don't change the second number....

Looks like it gets pretty cold in WA, if below zero a lot, use a 0W-30, otherwise a 5W synthetic will work...

Dont use a 10w30, you can use 0w30 year round. No need for a "thicker" first number.

You can do it but why change the first number either

Or you can just use 0w-30 all year long.

Welcome to the Forum!

Consider 0W-30 all year long or a 0W-20 in the winter and 0W-30 in the summer.

Absolutely no harm in using 0w30 year 'round.

German Castrol 0w30 is not the same as most 30 weights meant for most American or Asian cars.

So for the OP I wouldn't choose it I'm trying to decide between a 20 and a 30 weight oil. The GC is nearly a 40 weight.

OP, if you're thinking about a zero weight and are tempted to go to a 20 weight even if your vehicle requires a 30 weight consider this.

Buy M1 AFE in both 0w20 and 0w30. Use 1 quart of 0w20 and balance 0w30. See if you like it and get a UOA. Take it from there to decide on what mix % is safe.

It's certainly heavier at operating temperatures. Nonetheless, it still is a 0w- multigrade and conforms to those standards. For the OP, as you mention, a GF-5 rated lubricant is more suitable.
