Went to get an oil change today and the local dealer only uses 5w-20 fully synthetic on all cars. Went ahead and did the oil change since I'm on holiday in Mexico and I don't have many options. Am I okay with the viscosity of 5-20 on my rig??!

No vehicle listed in your profile or post. Please update your profile by clicking UserCP when viewing forum in web browser. Either way yeah its probably fine but if you have a Turbo I would probably go thicker when you get home.

You'll be fine. Depending on the age and mileage of your car, the oil pressure may sag a little when it's hot but should be of no concern, just know that it is normal.
Curious though why the Mexico dealer would have selected this as their year round oil.
Brand, subbrand, sheer strength (wear rating) and class rating are more important than the weight. What synthetic oil did they use?

2017 lab hyundai santa fe, fwd, última with tech package. My rig Has the 3.3 L, V6, HYUNDAI MÉXICO service dude said they only utilize Castrol edge full synthetic 5w-20 in all their customer vehicle...

Apparently Hyundai recommends 5/30 but you'll be fine. I would just drive until your next oil change is due then get back to spec.
Here is what the manual recommends: http://www.hyundaisantafemanual.com/santafe-346-recommended_sae_viscosity_number.html

Actually, I'm used to running 5W-20 and personally now running 0W-20 - I'm a bit surprised HMC recommends 5W-30 in a non-turbo, but I wouldn't sweat it, - you'll be fine.

Good oil, shouldn't be a problem. 5W20 is more commonly used in warmer climates.

You should better use a thiker 5w30 full synthetic oil (for Mexico even better 10w30) if you want your engine last. Thinner oil doesn't provide enough mecanical protection to this GDI engines when they get hot. Just reserch on this forums about gridling noises, metal shavings, failed rod bearings, stalled and replaced engines.
Hyundai MPI engines on which are based this new GDI engines were very reliable. That is the reason to discard a design flow in first place. It is the pushing for fuel economy by using thinner oil which is not working well enough with direct ingestion. IMO.
By the way, korean oil brand "Zic" doesn't even offer 5w20. I would like to see what oil specs they recommend in Korea? In Russia, for example, 5w30, 5w40 for non turbo.

With Castrol Edge or another well known high quality full synthetic you have little to worry about using 5W20, especially in the winter months. Use what your owners manual tells you to use.

I've used exclusively Mobil 1 5W30 in The Bride's '07 Tucson 2.7 V6 since she bought it brand new. Since it's pushing 90,000 miles I'll likely start using their high mileage oil soon. My '12 Santa Fe 3.5 V6 can use 5W20 according to the manual. With 44,000 miles on it I just bought it and have yet to do the first oil change but that will be the way to go with that car. Of course, filters get changed every time.

Somewhat on the fence on the W20, W30 thing.

My 2016 Accent owners manual says 5W20 or 5W30 - and maybe 10W30.

I've read a few people say they had valvetrain noise with 5W20 and went to 10W30 and it went away.

I put 0W20 at the first oil change and don't hear much valve noise, but it's only 5K miles on the engine.

I might consider 0W30 - but it's almost twice the price.

 

[Toltok]

Sonata 2015 GL, 2.4, always full synthetic oil, switched to 5w30 last summer. Motor is working more smouthly since then. No way I'm going back to 5w20 even for the winter.

 

[Toltok]

5w20 and 5w30 for the same temperature ranges. 10w30 for wormer climates.
But, 5w20 for fuel economy poushed by the US gov and EPA.
And 5w30 for healthier engine.

 

[Tiger-Heli]

Not trying to start a flame war, but there is a member on the Accent forums with 345K miles on the engine and no oil usage between changes, and he uses 5W-20 synthetic and the Hyundai OEM filters.

Not saying I personally agree with that, but I think if you regularly change the oil with just about ANYTHING remotely close to within spec you are unlikely to have oil related problems.

 

[Toltok]

345k miles. It would be interesting to know what kind of the engine does that Accent has: the older multiport injection or newer direct?

 

[Tiger-Heli]

http://www.hyundai-forums.com/rb-2012-accent/541017-accent-2013-gdi-engine-oil-gets-black.html - It's a 2012 RB series, so it is the newer GDI. (There is also a member who's had three engines replaced for bearing issues between 90 and 100K miles, so I'm not saying the engine/oil is perfect ...

 

[Toltok]

Thank you Tiger-Heli, it is good to know that yhis new gdi engines can last that long.
Just another confirmation that they just need a proper maintenance.
Interestingly, this fall, my dealer sent me a letter advising to do oil changes every 4 mounthes / 4000km instead of 6/6k they were doing befoure.
They know, Hyundai is positioned like an economic alternative to Honda/Toyota, so it should be a very good reason to poush people for more frecouent oil changes, apart of the obvious profit of cause.

Yes, but that's a bit ridiculous - it was (I think) 6-months and 3K miles in the 1990's - and that is less than that even.

If Hyundai is trying to compete, Toyota (USA), not Canada - is saying 12-months or 12K miles for OCI, and Honda basically has the car tell you when it thinks it is time for one.

All Hyundai vehicles are built the same for the North American market, the weather and the oil doesn't change when you go across the border. The dealer is just trying to convert service dollars from your pocket to theirs. The 6/6 is the the suggested change for severe service and will be just fine. If your using synthetic oil and feel comfortable with it, I might even stretch that to 1 year/11,000Km.

 

[Tiger-Heli]

Tend to agree, but yes and no. Hyundai has a LOT of features on the Canadian Accent that are unavailable on the USA model and vise-versa. Come to think of it, Toyota does also on the Corolla.

Now the engines are the same and I think the Hyundai oil and OCI's may be the same.

Interestingly, the Toyota OCI is 12-months/12K miles in the USA where Toyota gives you free oil changes for 2-years, and it is similar to 6-months/6K miles for Canada where you have to buy your own oil changes.
