Mostly M1 but recently got back on the A word bandwagon.
Over the past 14 years, we have owned about a dozen Hyundais. Their engines don't have any accurate lubrication "specs." Suppose you go out and look up owner's manuals for various Hyundai models in European countries, Asia, and the Middle East. In that case, you will notice that they allow for a myriad of viscosities for the same engines that they sell in North America. A couple of years ago, in all their repair manuals for all engines except hybrid powertrains, Hyundai listed a viscosity chart ranging from 0/5W-20 up to 20W-50. To whit, they categorically forbid the use of 0/5W-20 in Middle Eastern countries.I do short OCIs so as long as it meets the specs for my engine it comes down to price, price and price.
I meant 5w20, 5w30, or 10w30 which is listed in the US owners manual. I’m aware there isn’t any “specs”. Maybe I should have phrased it differently?Over the past 14 years, we have owned about a dozen Hyundais. Their engines don't have any accurate lubrication "specs."

And I repeat, Hyundai does not have an OEM approval process for lubricants. Not even for their SP-IV/SP-IV-M/SP-IV-RR transmission fluids, which are nothing more than Dexron VI/Mercon LV type fluids.
Consequently, in your opinion, what do you think that "meets the spec" means when it comes to Hyundai engines?
Oh no, you phrased it right, and I wasn't trying to be a smart ... you know what I was just honestly trying to gauge what you thought was the spec for your vehicle's engine, while at the same time trying to inform you that Hyundai did a poor job at clearly defining for owners what works best in their engines. They could have certainly done a better job IMHO while avoiding engine problems due to the deadly mix of low viscosity oil and fuel dilution. Lately, or starting with the 2021 model years, they started "enforcing" stricter viscosities, even in their repair manuals. And good God, are their service/repair manuals terrible, and borderline useless. I regretted spending $40 for a week of access to their database when I replaced the transmission fluid in our Santa Fe SUVs, as I didn't learn anything from there.I meant 5w20, 5w30, or 10w30 which is listed in the US owners manual.

nope. mostly use t4 shell and mobil 1.Anybody loyal to one brand? In person I claim to not be brand loyal but I'm secretly loyal to Castrol. We own a 2019 KTM exc-f 500 that I've secretly used supertech cf2 in 400 hrs. Internals near perfect with that "Wrong" oil. We did a top end rebuild last week. Vehicles,tractor get the "Best" but honestly I think the loyalty thing when knowing what we know about lubricants is kinda like when u perfer a sports team; Not necessarily that you actually believe "YOUR" lube is any better than the next guys.
