d.i. turbo: what conv oil if you had/wanted to?

[wemay]

Since Hyundai only uses conventional oil during maint visits (you must request syn or blend if wanted), and synthetics isnt required according to them at their 3 or 5k mile oci, most American/Canadian households, BITOGers not withstanding, will be using conventional oil.

What conventional oils would you consider?

PYB
GTX
VWB
QSGB
MS5K
Havoline
etc...

PYB

 

[SwampSurvivor]

PYB or MS5K.

 

[Zaedock]

I've always been a QSGB fan.

+1 to that logic.

I'd be leaning towards QSGB and PYB, but they are all fine choices. If I was in a hurry, GTX would be the no brainer since it's easy to find on sale. If I wanted to stay away from Walmart, Canadian Tire, or parts stores of any sort and wanted to buy at a distributor, it would actually be Formula Shell or Mobil Super 1000.

Are you of the opinion that the low Noack number associated with the 5w20 translates thru the entire viscosity range? It sounds logical to me.

Good question, and I don't know, really.

Does Hyundai not allow the use of 5w-20 grade?

 

[147_Grain]

PYB / QSGB / MS5K.

With the D.I. engines and fuel dilution, suggest you keep OCI's to 5K.

 

[wemay]

QP,
Inside the manual it only says 5w-10w30. The back cover lists 5w20, 5w30 and 10w30 as allowed with no distinction as to which engine uses what. So in a literal sense at face value, it may. But for sure, 5w-10w30. The Santa Fe Sport manual does not list 5w40 as permitted either (in case anyone wonders).

I'm surprised GTX 5w30 isnt a first choice for some, having an almost dexos like,13.7 Noack number among the 5w30's according to PQIA.

 

[danthaman1980]

Out of those, PYB all the way.

We don't know if they're using GTL / GIII+ in PYB 5W-30, but PYB would be my choice regardless.

Since SOPUS prints the manufacture date on the bottles, you can always buy the newest batch you can find, and hope it is full of GTL

As others have said, keep the OCIs at 5k or under. D.I. Turbo in S. Fl. sounds like it would be hard on the oil.

I still think there was a lab error/mixup here. Hard to find 10w30 synthetic with no vii reporting at that level NOACK. Maybe they are using a new DP that has lower volatility solvent oil to (eventually) meet DEXOS I. In any event GF5 is reformed for turbo use (really this time

) as one of the targets.

Be cautious about reading too much into those NOACK numbers. Mola has commented on that already. I will say I like the low NOACK numbers. I'm not stretching it to the point that I somehow believe SOPUS is selling me PU in a PYB bottle at PYB prices or, if there was a reason to do such a strange thing right now (or at least at the time of testing) that it would be an ongoing or permanent thing.

Words of caution

None...I would never use conventional in a turbo car. I would use PP or Mobil1

I always used Castrol back in the day, but the cost is typically a lot more now compared to other choices.

Thread concerns conventional.

 

[renegade_987]

All of them you listed would probably work out OK, but as far as the life of the turbo synthetic would be much better

I would have to agree that I would never consider conventional. Many people on Hyundai forums would post about the differences they felt switching from conventional over to synthetic for their turbos and using a slightly higher weight oil, such as 5w30.
