Genesis 0W-30 Vs 5w-30

[BobsArmory]

Amsoil, HPL, Mobil1 AFE, Mobil 1 ESP & Redline all make great 0W-30 oils. All would provide great protection flowing well during the chilly days and yet giving more than adequate protection in the summer. Some people poo poo Mobil1 advanced fuel economy around here but I have to say that a couple years ago I made a run from Michigan to Phoenix and back with a Chevy Equinox 1.5 liter turbo and Mobil1 AFE. The used oil analysis on that oil after my return to Michigan was stellar.

That said, nothing wrong with a 5w-30 for summer & 0W-30 for winter. My opinion? Just grab any name brand or boutique 5W-30 0W-30 and you will be fine for your summer drive.

Mobil 1 ESP 0w30 is all that Genesis needs for a good healthy life

0w30 vs 5w30 wont make the difference you think they might.

Your engine is a reliable one rather than supe high performance. It will be much easier on the oil then you expect.

If you are seeing really high temperatures, you could consider thick xw30 oils (ESP is the first one comes to mind), or a thin 0w40 (Mobil 1, Pennzoil Ultra Platinum)

AFE is a very different animal than ESP. I would personally not run an oil designed to lose viscosity on purpose in any turbo engine, unless maybe your engine needed a 20 grade and you used AFE Xw30, since that’s essentially a 20 grade oil with an incorrect label.

ESP on the other hand is very robust and would be fine for the OP’s wants.

I think you may be over reacting just a little bit. It's a Dexos Gen 3 & API licensed 30 weight oil.

I'm not overreacting at all. Take it from XOM themselves. "Ordered by performance level...," We aren't going to end up in another discussion about how a manufacturer is secretly sandbagging their own premium product like the crazy talk posts about Purolator Boss, are we?

Mobil 1 Advanced Fuel Economy is designed to improve fuel economy. That is the opposite what usually turbo oils are designed for. It's not only its name, but also the group of oils that is part of on the Mobil's website - all of them are designed to improve fuel economy.
On the other hand we easily see that turbo oils have higher viscosity and more robust additive package (that are not associated with fuel economy) like the Mobil 1 ESP group of oils.

What would be the reason to run fuel economy oil in a turbo car, which runs usually hotter than N/A cars than a dedicated turbo oil?

We should call the feds and have them remove it from the store shelves immediately!

I don`t think this image is a support either in favor or against your argument. Does it "perform" marginally better, or a different animal better?

ESP is definitely the favorite arond here, and I would agree it is more on the protection side (I don`t think there is room for much doubt there). But for most people that extra protection might very well be washed out with more heat

Higher heat?

 

[altaylar]

Higher heat?

More heat*
Thanks for pointing it out

Sorry. I was curious where more heat is coming from?

The difference in viscosity would generate an undetectable oil temp difference, if that was your thought. Even the difference between 20 and 30 grade would be hard to measure.

 

[WeyounDS9]

I was under the impression thicker oil was better under high heat and had less viscosity loss/breakdown

That is correct (Source: Am a Chemist)

Edit: Also a turbo motor needs a good HTHS (high temp High Shear).
Sure, yours isnt really a high perfomance car, but in summer there is no need to go thin
I'd happily run a 5w-40 or 0w-40.

I currently reside in Germany and even though I dont have a turbo car, I take my V8 powered SUV over 100 mph for relatively prolonged times about twice a week.
I run a 0w-40 year around, despite my OEM recommneding (in the US ) 0w-20.
In Germany they used to recommned 5w-40 for this engine, but fuel economy matters here as well.

Edit2: In Germany we been seeing a lot of engine failures in high performance engines in recent years, that some indepedent master mechanics blame, at least in part, on too thin oils used these days (anything thinner than a 5w-40 which is the old standard in GE)

What? Protection being wiped out due to the somewhat increased HT/HS?

This is nothing but imagination.

Which is not some endorsement.

 

[altaylar]

I know there is this belief of "more is better" understanding in some, but a thicker oil, or thicker film does not necessarily mean better protection. If one provides adequate strength of film, how does a thicker film provide a better protection?

An API oil that shears out of grade on purpose, in search of potentially a tenth or two of MPG for CAFE, is entirely a different approach than something designed to stay in grade on an ACEA schedule.

ESP will always be more robust than AFE from initial pour until drain, by design. Under equal conditions, ESP is always going to provide greater protection than AFE, even if it is decimals of an MPG worse than it.

 

[SubieRubyRoo]

Your words, not mine. I simply said ESP is a much better choice than AFE for hardworking turbocharged engines, which lines up with Mobil’s own recommendations.

AFE is a resource-conserving oil, whereas ESP carries approvals for some of the most demanding European manufacturer specs currently on the market…

 

[altaylar]

Back then there

An API oil that shears out of grade on purpose, in search of potentially a tenth or two of MPG for CAFE, is entirely a different approach than something designed to stay in grade on an ACEA schedule.

ESP will always be more robust than AFE from initial pour until drain, by design. Under equal conditions, ESP is always going to provide greater protection than AFE, even if it is decimals of an MPG worse than it.

I know this conversation will not really lead anywhere, but from that stand point, why would not you get a one great higher AFE rather than 1 grade lower ESP? And at that point, why would not you get the ESP version of that higher grade as it will provide "greater protection."
And once you are there, why not to get AFE of a grade higher?
so on and so fort.

All I am saying is, we cannot say "thicker oil provide better protection" as that logic leads to an unbounded outcome

 

[altaylar]

Or actually lets put it this way, from your expectation, at what milage would this engine running purely on AFE would cause an oil related problem that could have prevented if the owner instead used ESP?

Will the owner keep the car hallf that milage?
How much would he saved if he used AFE instead untill then?
