Synthetic or not
If u are in colder climate 5w20 is good enough
More important is Changing the oil filter every 5K miles. Might as well put cheaper oil every 5k miles
No one can control air quality. It is same whether u put synthetic or not. Filter will become dirty no matter what

i asked lexus corporate about using 5w20 conventional oil and changing every 5k. they said they want the 0w20 for cold starts?

0 weight flows much faster at colder temperatures than 5 weight. That faster flow reduces engine wear at start up, which is when most wear occurs, especially in colder weather. Thus you get to full oil pressure faster and critical components are lubricated more quickly. Increases mileage too, which is the main reason they want it.

Yeah... you only have the viscosity of the 0 weight for a few minutes at the most. As the oil continues to warm up, it continually migrates towards the viscosity of a 20 weight oil.

Pure synthetics can go way beyond 10k miles and have been able to do so for many years now.
At the other extreme is my buddy Patrick. Back many years ago when we were just beginning to drive, his folks got him a beautiful blue Fiat roadster (forget the model, but boy, was that one sweet car). But Patrick had a particular quirk--he didn't believe in changing oil. Ever.
About 3 years go by and his engine is trashed. Rings, bearings, lifters. Can't imagine what the oil looked like in the bottom of the sump; perhaps closer to roofing tar.

I like that advice.

It's really more of a reminder to me than to anyone else.
As for the oils, the "thinner" (lighter) weights are going to flow more easily which can potentially mean less residence time in hot spots and potentially more cooling effect on those hot spots. At the same time, though, it provides a physically thinner film of lubrication between friction components, and that can result in increased wear if the driver hammers the throttle on a regular basis because of the surges of forces within the engine that can overcome an overly thin lubricant film layer.
How you drive (push or baby the engine for two extreme examples) is just as important as which oil you use and how often you change that oil, and they all go hand in hand as different components of the wear and efficiency performance.
