Are 2019 Hyundai and Kia 2.4's forced-induction DI engines?


For a naturally aspirated direct injected vehicle to suffer complications due to LSPI is exceedingly rare.

Trust me, not just those forums


WHAT ARE Y'ALL TALKING ABOUT?!?!?!

sorry, couldn't resist

2008 535xi, n54, twin turbo and direct injection (ask me about walnut shells)
2016 macan, twin turbo and direct injection
2009 911, 9a1, direct injects but no turbos (guy on rennlist has bore scoring and then the hysteria followed saying was from LSPI)

Went from CPO to an Endurance after market warranty for 4/48. Have to follow manufactures maintenance requirements. So Mobil 1 0w40 it is. (Which the ratblog likes for whatever that's worth - after all he is an expert as he says over, and over, and over)

The BMW? Yes, i would say intake valve deposits are a clear possibility but not LSPI. I just haven't read where this is an issue with European makes.

I also haven't read of Porsche having issues with either, IVD or LSPI. The 2016 may be too new to comment on but the 2009 seems like it's out of the woods. If this were an issue, it would have come up long ago.

IVD is definitely an issue with BMWs. And LSPI is an intermittent issue with the TGDI Prince engine family (BMW/Peugeot joint venture for MINI engines); they refer to it as "Super Knock".

Thanks for that info. I wasn't even considering this engine family. Makes sense.

Exactly... As evidenced by a 10 page thread about to prefill or not prefill a doggone oil filter

How about a full-synthetic CK-4/SN PLUS HDEO like Delo 400 XSP 5W-40? HTHSV = 4.2 cP as opposed to 3.6 cP for an A40 0W-40; so, you get a lot of extra protection against oil-film breakdown. LSPI protection is included. You also benefit from less intake-valve deposits (IVD) because SAPS is lower (1.0% vs. 1.34%). Despite the initial value being lower (10.1 vs. 12.6), the TBN should hold nearly as well and perhaps better because of the modern Ca + Mg mixed detergent.

The current (2016) A3/B4 spec is outdated in my opinion. ACEA is working on to incorporate the LSPI protection as well as other improvements in the next generation ACEA specs. They have fallen behind API/ILSAC in this aspect.

The ratblog is FOS, but Mobil 1 0W-40 is good stuff.

Naturally aspirated direct injection engines don't appear to suffer from LSPI, it seems to require boost.

Ahhh
..... That is really interesting to learn. This is a good thing to know for future reference.

Moly, and Zinc are LSPI quenchers, maybe look for oil soluble moly treatments w/o calcium added. As a bonus find pao.ester base stocks as well if possible. No not recomending redline as they are behind the 8 ball when it comes to offering a lspi friendly formula. However, the higher quaity base oil, the less lspi has happened. When I discusse it with DAve from redline he had never heard of an lspi event with his product, but I still don't think he gets it. It is a simple fix, they need to have di offering low calcium high mag and until they do, not a good choice. However, Amsoil SS has high moly and is sn+ friendly. Ravenol probably has some good offerings, need to give it a look.

You've pretty much described every dexos1Gen2 offering.

lower Calcium
no Sodium
higher Magnesium
added Molybdenum

But some studies also point out that unless you're using GrpV base stock, lower base stock is actually more effective at quenching these events. Grp III being better than GrpIV and GrpII better than GrpIII.
Yes, it is still a complicated phenomenon.

Ok. This is all new to me. So how do you tell if an oil is a base I,II,III,IV, or V? Is there a list?

 

[wemay]

Taking into consideration that these companies never divulge this "proprietary info."
Most Synthetics are probably a combination of GrpIII and GrpII. Some, like Mobil1 EP and AFE use more GrpIV (pao). Regular Mobil1 and Pennzoil Platinum process natural gas to achieve a remarkably pure, high end GrpIII (some call it GrpIII+) GTL (gas to liquid) base stock. Although that test only discusses base stock in the context of LSPI, there are many more benefits to using higher quality base stocks than drawbacks.

But all this does is convolute the issue further. If the concern is LSPI, I'd just choose an oil which meets dexos1Gen2 if driving an American or Asian vehicle. I doubt these issue exist in your case. Most oils recommended for your stable are very high quality ACEA with manufacturer approvals.

 

[Triple_Se7en]

Until further notice, my D.I. will incorporate 5w30 jugs that say dexos1Gen2 and SN Plus

You can't really, and it doesn't matter.

Pretty much and agreed.

Did you read the list of his cars? 2/3 are TDI.....good grief.

2009 911, DI, no turbo. Still under warranty so I need an A40 oil. Are there any SN plus A40 oils?

2016 Porsche Macan, 3L twin turbo DI. 100K miles so no warranty issues. There is a Joe Gibbs DI40 that the Porsche forums recommend for the DI 911's. But it has no certifications. Thoughts? Or just run with an A40

2008 535xi, twin turbo, DFI
