Seems my Hyundai likes to chew up oil pretty good. My last run of Max Life Full Synthetic yielded a 1.9 TBN at 5,000 miles. What do you think?

This seems pretty normal for Hyundai engines. The TBN wasn't bad at 2.8. You probably could've gone to 5000 miles no problem at all.

Agree 5K would be a good limit stop.

 

[AKhan87]

Holy TBN...3k on PP and TBN is 2.8...never seen that kind of TBN rape.

QSUD 5k OCI? It's cheaper and at the moment better on paper then PP & PU

Was this PP w/ PurePlus or old PP?

As long as you fall in this ^ range.

 

[Merkava_4]

For as much money as they want for that oil, you would think they'd be all zeros at 3,354 miles.

 

[zerosoma]

Based on this information, how long should I go on a conventional like Havoline? I was thinking, 3k tops?

 

[bigt61]

2.8 TBN after 3400 miles seems fine to me. At 6000, it might still be over 2.0. How long was the oil in there - months? Did it go all winter? What kind of driving do you do...city/highway? Did you add any make up oil? Was the oil level low? You may be reading too much into this UOA and are just jumping into worst case scenario conclusions.

It was a winter fill yes. It went about 5 months. No make up oil, no useage. Mostly highway.

Lot of iron for the miles run.
TBN is killed with an oil that normally has good TBN retention.
The sodium is just a leftover from the previous run of Valvoline.
PP is a good oil that this engine pretty well killed in 3.4K.
What does Honda know about engine design and build that Hyundai has yet to learn?
I'm thinking that 4K might be the limit for any oil in this engine and it wouldn't matter whether it were syn or conventional.

TBN doesn't drop in an linear fashion. It might drop to 2.8 in 4k miles but only drop to 1.0 after another 2-3k miles. This oil would still be fine after 5000 miles.

 

[fdcg27]

TBN may not drop in a linear fashion, but I posted a UOA here last spring of a PP run of a little more than double the miles of this one and the oil had more remaining TBN.
The OP is right in that this engine does seem to beat up the oil.

Someone engines are just super easy on TBN. You can't really compare anything to Honda 4 cylinders.

 

[fdcg27]

You caught me on that pretty quickly and we haven't even had the Honda in question since last September.
Yeah, Honda fours seem to turn in nice looking UOAs on any oil you happen to run in them.
I wonder if the opposite applies to Hyundai V-6s?

 

[901Memphis]

My best guess is Hyundai engineering isn't as good as Honda for the 2004 model year.

Newer Hyundais are nice but they have come a long way in just 10 years.
