What kind of car do you have?

I have a 2016 Scion/Toyota iA which has a Mazda Skyactiv Direct Injection mill and calls for 0w20. Same goes for the wife's Corolla just a plain old MPFI Also takes 0w20 but much easier on oil.

Since 2012 I been a Toyota man and following manufacturers recommendation for 0w20.

Is that why Toyota specifies 0W-16 in its GDI engines?


My new 2018 Toyota Camry specifies 0W-16 oil. However the owners manual states that 0W-20 is acceptable, and can be used. So that is what I'm going to use, because I can't find 0W-16 on the shelves anywhere by me. And I'm not going to the dealer and pay over double, or order oil on Amazon. I'm sure eventually it will become more available. But in the mean time I'll just use 0W-20. Again, per the manual.

Didn't it also state that you had to revert to 0W16 at the next interval ?

I can buy 0W16 at my local parts place in OZ...

If it were mine i would simply run a 0W-30 or 5W-30 with the same specs

Yes.

Plus these are the individuals that keep their vehicles for 500k miles where it will make a difference by then.

I agree, we should go back to hand cranking our vehicles and get rid of power windows and the like. Hand crank windows worked just fine.

This must be the Friday night thick vs thin thread.

Kia and Hyundai 2.4 And 2.0 GDI engine’s drop like flies. Connecting rod bearing failures. They specify 5w-20 on the oil cap. When Kia sends you a replacement 2.4 or 2.0 long block, you better use the Mobil 5w-30 Kia supplied to fill the sump or the warranty claim won’t be paid. Coincidence?
NOPE





I read the call campaign process for engines under the TSB (metal shavings from mfc error at Alabama plant [for certain years]) that does call for 5W30 (pass or fail)...

RCMN-15V568-8190.pdf

The oil used to fill, pass or fail

I wonder why Conventional is used if "pass"


The campaign

0w-20 vs. 5w-20?

There's no benefit to using the 0w-20 in hotter climates like SoCal, South Texas, Gulf Coast and Florida, etc. In fact, the 5w-20 would probably offer better protection year round. Maybe the engine wouldn't notice the difference until 200K, 300K, or more miles. Doesn't really matter. There's no reason to use a 0w-20 in those hotter climates. One size isn't optimal for all environments.

What’s the difference between the two?

According to whom?

When I go to Walmart for oil purchases, I cannot find any that say xW-20. That's because there aren't any.

What is so hard to hit the 0 or 5 keys on your internet device, instead of x?

+1.

Once your engine is warmed up they are the same temp. Its clear some peoples biases are based on misunderstanding.

Yes. Then it also states something about a higher viscosity oil if the vehicle is going to be run for long periods at high speeds in high temperatures.... Or words to that effect. I'd have to look it up. So it's a little contradictory.... Or you could buy another house in a cooler climate, then live there for the next oil change.

Don't you refuse to use the 4 cylinder mode in your Corvette?

I don't refuse to use it actually, I let it go into 4 cylinder mode most of the time, which is why I am able to get 40 MPG on the highway and am averaging 25.7 MPG since my last oil change (almost 4000 miles worth of driving)

I agree, DI is poor engineering. I call it tech in reverse.


I think you are wrong about that. DI allows for more power and more fuel economy. It just needs to be tweaked in some applications that have more carbon buildup than others, but in general it's a big step forward in engine technology.
 
0W20, 5W20 and 0W16 sounds more technical than 15W20 and 10W16, therefor must be better and cost more.

Where can you find 15W20 and 10W16? Delo 400 SAE 20 & SAE 10.
