As i wrote earlier, I've owned other turbos that never saw syn. Plus, wasn't part of the development of SN and ILSAC GF5 to better protect turbochargers as well? This turbo is also partly coolant cooled. The Maxlife is sounding good though.

LMAO!! Boy, no sooner said then the flood gates opened. The Maxlife idea sounds interesting I must admit.

That's your get out of jail free card right there.

You can get away with conventional. Turbocharged cars that get worked hard would benefit the most from a quality synthetic oil.

Turbochargers spin at very high RPMs and see high operating temperatures, whole different animal from natural aspiration

Agree with you. This vehicle is rarely driven spiritedly though.

Supposing that OP's new engine is indeed both turbo and GDI, I agree that after the break in period, and that could be as early as the next oil change or as late as after 30K miles, in order to protect the turbo, a 10W30 (the grade that is suited to OP's climate, yet does not really sacrifice fuel economy) that is synthetic of some sort should be beneficial to OP's engine. Such SN GF-5 Group III synthetics as SynPower 10W30, Pennzoil Platinum 10W30, Quaker State Ultimate Durability 10W30, Super Tech Synthetic 10W30 (if underneath the bottle it be indicated with "WPP" or. "WNE" for Warren). Besides the favorable climate, 10W30 grade of any kind of motor oil is more shear stable than its 5W30 counterpart, and for this reason 10W30 Group III synthetic (chemically dino, but essentially synthetic in performance) should help protect the turbo for longer and should be a bit stouter in resisting fuel dilution caused by the DI system. Pennzoil Ultra is a tick higher in SAPS, but not really a disadvantage against DI, because its Noack is very low; only problem is some areas the OP can easily buy it off the shelf for reasonable or even low prices, other areas no.

If indeed OP's system is both turbo and DI, as far as easily acquired conventional optimal for OP's engine, I recommend Mobil Super 5000 10W30. It is low to mid SAPS therefore good for OP's engine, its additive system especially resists oil oxidation and also TBN depletion is slow, even though the starting TBN is on the low side. A BITOG member don't remember his name, did a series of used oil analysis for between 7K and 10K OCIs utilizing Mobil Super 5000 5w20 (under normal service, not severe service) on his Ford F-150 with both turbo and GDI (the EcoBoost), actually got good results. In his case, he did the right thing by not utilizing the 10W30 grade, not only because of manufacturer specs but also because of the design of the engine. The predecessor engines installed in F-150s were called modulars and they had very long timing chains and particularly narrow oil passages, therefore very rapid lubrication especially at cranking, was required for reliable operation and durability at all ambient temps. It is safe to suppose that something similar continued with the EcoBoost which now specs 5W30 instead of 5W20 because of the turbo and DI. Although OP also is equipped with variable valve timing, otherwise the design of OP's engine is different, as the manufacturer specifically says 10W30 is good for OP's typical ambient temps. So, Mobil Super 5000 10w30 for somewhere between 4K and 6K is most likely a cost effective, easily available conventional alternative to 10W30 mainstream synthetics that carry moderately high TBN (mid to high SAPS). And either way, OP will experience the same fuel dilution, etc. so that OP should not expect to do extended drain intervals, unless OP's vehicle be operated under normal service.
 
There is no absolute need for synthetic in a Hyundai GDI turbo engine when severe service intervals are followed. If extending the interval beyond the recommended 3500 miles, I would recommend a euro-style long life 5w30, meeting ACEA A5/B5 or A3/B4 standards.
I work in Hyundai service. Our bulk oil is Gulfpride Advance Fuel Efficient 5w30 synthetic blend. We have not had any issues with the durability of this oil or our previous bulk oil, Formula Shell 5w30 in the GDI Turbo motors.

Thanks salv,

Depending on what type of sales I see, my options will be open but its good to know that synthetic is not an absolute at my very short oci. Plus, I enjoy changing the oil.

On top of what Merkava said, MaxLife is SN/GF-5 rated.


Thank you Garak,

I am concerned, hearing how strict Hyundai/Kia is with their warranties, that a high mileage oil would be frowned upon.
 
I'd run motorcraft 5w30 synthetic blend or full synthetic. Both give impressive UOA and blend should last 5k, and synthetic 7,500k/6 months. Plus its a relatively cheap cost to buy.

What gives the impression Mobil Super 5W30 or any 5W30 could not handle a 5K OCI?
 
The 5w30 is a good idea IMO. I am up for an OCI in our KIA right now and am going to abandon 5w20 and move it up to 5w30.

Looking hard at Castrol's GTX Synblend Dexos, would be a good one to consider. Probably what I'll buy unless I can find another fill of clearance Ultra.

If you're going to do your own maintenance be sure to keep those receipts!
 
Welcome! Great car!

Synthetic oil use:

1. Hyundai (owners manual) does not require it.
2. Your Hyundai Service Tech said it isnt necessary.
3. Our resident Hyundai Specialist, Salv agrees*.
4. SN/GF4, as you said, devl'd in-part for Turbo protection.
5. SN oils may 'contain some GIII base stocks' (who knows).

*Salv says it isnt necessary but does recom'd it for folks not strict with their oil change schedule.

Don't let my signature fool you, i too have used conventional (and probably will again) as my driving habits resemble yours.

Piggy-backing KCJeeps recom'd, All the blends now dexos certif'd are great choices too, but may not be necessary either..

Considering it meets the specifications they call for exactly (and exceeds them, actually, having dexos1), there's not a lot they can do about it. They really can't say to use an SN/GF-5 rated 5w30 (or whatever viscosity) except MaxLife, unless, I suppose, if Oil Changer authored the manual, but that's another issue.

It will be perfectly interchangeable with any other SN/GF-5 motor oil of the same viscosity. If price and availability are good, I'd use it.
