Well, bought mine brand new, and I typically drive the wheels off of my vehicles. Other than the original engine puking out on me, it's a really nice car. The replacement engine has been good so far, fingers crossed. I'm also curious to see what happens. After just 3 days of having the VRP...

I don't keep mine in eco around town any more. But on the highway I do. My Sonata immediately shifts down if going up a decent grade, the RPM won't get low enough to lug the engine. But around town it does want to upshift too quickly.

After doing some research I believe the TBN additive package in the Ultra was a little better if memory serves, so went to it. And before VRP came out, THE hot oil at the time that was getting all the rave reviews was PUP. I was also running it in my truck at the time so it just kept...

Quaker State Ultimate Durability was the "recommended" oil in my 2015 Hyundai Sonata and what I started off using. And the research I did at that time pretty much stated it was a very good oil, and it was usually cheaper than competing brands too, so good all the way around. However I...

Oh good gosh.🙄. Well, there goes my marketing career down the tubes.☹️

Good question actually. I don't know what the sales have been (I think anecdotally it could be said sales have been pretty good, but that's not solid data). However, by all indications it seems to be a "breakthrough" oil that is doing stuff that no other off the shelf or mass market oil seems...

Valvoline Restore and Protect 100,000 mile oil?😆

Naw, no need, that's what I've got several of y'all guys for so I can ride your coattails. 😆. But I promise to give y'all the credit.😁

2015 Hyundai Sonata 2.4 N/A. Right at 50,000 miles on replacement engine. No oil burning so far, oil completely full at change this morning. Almost exactly 3,000 miles on Pennzoil Ultra Platinum 5w20. Went with Valvoline restore and protect and up the viscosity to 5w30 on this change with a...

I keep seeing that the Boss and the One are still good, I have a few One's that I got a while back and kept in stock when I caught them on sale in Amazon. My and my wife's car both use the same size so I stocked up. If they have indeed diminished in quality I definitely have no issue going...

There have been a few oils over the years that seemed to grab a huge amount of attention when they came out. The original Mobil 1 full synthetic comes to mind. I know when I was in high school auto shop in the early 80s that was talked about like it was some sort of unicorn magical elixir that...

And I'm sure they pay for that privilege.

LOTS! Especially those of us with GDI engines, and probably those with turbos as well. On the other hand, my old 1996 Ford Ranger that doesn't burn a drop of oil and still looks relatively light and clean when changed? That probably doesn't need it.

Mine was no hassle at all as well. Now one requirement is that the car has been brought in for all recalls and updates, which I had done. I have heard of some horror stories where people had not brought their cars in for software updates and when their engine went Hyundai would not honor the...

Pennzoil Ultra Platinum is mediocre? Ok, I just noticed I stated Pen Platinum. Actually it's Pen Ultra Platinum I run. Everything I have researched points to Pennzoil Ultra Platinum being a pretty "top of the line" level oil. But I assume your reply was geared towards the basic Platinum...

Funny thing is, I was watching one of the many car/engine based YouTube channels that I do a few weeks ago, and the host was tearing down a Theta II engine relatively close to the same year I have. He stated he thought it was actually a decently designed engine, fairly basic, and evidently it...

Well better than it going out the tailpipe I guess.😆

My 2015 Sonata 2.4 Theta went out on me August of 2022. Literally sounded like the loudest diesel you'd ever heard. I was surprised I got it to the dealership for them to examine it, had to drive it about 25 miles to their shop, not sure it would have went another 2-3 miles before completely...

Did he have the same issue with the 2nd one?

I have a 2015 Hyundai Sonata, and the original Theta II engine was one of the "bad" ones. I've never heard an engine knock so badly, it went at about 122,000 miles. I had no issue at all with my local Hyundai dealer replacing the engine on warranty in September of 2022. Almost 4 years later and...
