"Zero-weight oils are designed to reduce emissions during warm up. If the wrong oil is in the crankcase, it will change the three to five minutes it takes to bring the combustion chamber up to temperature. This will also alter how the variable valve timing works. It can also have implications for the catalytic converter.
Always use the motor oil viscosity recommended by your vehicle manufacturer. Using a different viscosity (thinner or thicker) may cause oil pressure and oil supply problems, especially in late-model engines with cylinder deactivation and/or variable valve timing (VVT)."

It depends - one brand's 0w20 can even higher viscosity than another brand's 5w20.

Here is Castol's 0w20:
Viscosity @ 100C, cSt ASTM D455 9.1
Viscosity @ 40C, cSt ASTM D455 44.4

Mobil 1 extended performance 0w20:
Viscosity @ 100ºC, cSt (ASTM D445) 8.6
Viscosity, @ 40ºC, cSt (ASTM D445) 44.9

Mobil 1 extended performance 5w20:
Viscosity @ 100ºC, cSt (ASTM D445) 8.9
Viscosity, @ 40ºC, cSt (ASTM D445) 49.6

The Castrol is thinner at startup but thicker then the M1 5w20 at full temp.


Their viscosities are different.


Better on startup wear if you engine can handle a thinner oil.
I'm just here for the mindless arguments about change intervals and viscosity.

Would it create issues to put 0w20 into a car with recomended 5w20? this will go in the engine editing July. ty

*Edit* Due to overwhelming response, and my own concern, I will stick with 5W20. I am a bit surprised that some manufacturers have slightly (perhaps negligibly) different viscosity than the others. Call me superstitious, but I will now stick to the manufacturer that I use for change oil on a regular basis. I have a 07 Mitsu endeavor, at 87k miles, and I know its probably sensitive even to a finger touch.
My Lawn mower has a Honda engine, so I will be using this oil with the mower, and stick to Pennzoil with the car.

Thanks to everyone who contributed.

Use the one designated by the manufacturer. Not worth damaging your engine for just a few dollars less. In fact someone mentioned the 5w20 available for the same price.

In for one for the Honda...$5-$8 cheaper than M1, not a huge difference over 10k miles but worth a shot. I'm curious to see if my Blackstone results are different with this vs the M1 in my last sample or the Honda OE oil before that.

0w20 and 5w20 are simply the same.

0w20 will be marginally better than 5w20

why would you thrust someone else with something so important like engine oil. just check your owners manual. if you don't have one then just state your vehicle year make model and someone will gladly find your answer for you

I now order all my oil and oil filters from Amazon. I use this Magnetec oil now since it reaches this price point off and on. I just wait for this price and order a few ahead of time. I stay away from s&s since I'll get charged the prevailing price at refill time.

I used to get all my oil and oil filters at Wal-Mart, but no more. A huge futile waste of my time there. Inveribly Wal-Mart's shelf will be empty of a motor oil or filter (both very common brands, grades and sizes). The employees will be too lazy to check backstock and say they don't have it if it's not on the shelf. If I online order them for store pickup, I am forced to wait in the returns line since the online pickup desk is adjacent to it and never manned separately.
