Langdale Kia in Valdosta GA found one for me and had it shipped in.
A comment to your first statement, Sometimes....................... You and I both have one of the better motors Hyundai/Kia makes, almost all other Hyundai/kia non-turbo motors made by the auto maker have metallurgy problems. The hypereutectic pistons in the turbo motors are the correct hardness as not to galling up like he soft pistons of the non turbo motors. 4.5 billion dollar lost because of incorrect piston and bearing metallurgy choice. By the worlds largest metals company. 10 years and running. I know the OP N-Line 2.5 will live a long life, I just want to see how the naturally aspirated 2.5 is going to last. It would last if it used hypereutectic pistons like the turbos, but I could see Hyundai using the same soft piston metallurgy they have been using for the past 10 years JUST so the top Hyundai execs with the engine rebuilding companies can embezzle money buy feeding their privately held engine businesses with warranty Hyundai/Kia motors. You just can't screw up 10 years AND RUNNING with out trying to do it.
In my Hyundai turbo, I ran Mobil 1 ESP 5w-30 for awhile with good luck, I have switched to Redline Performance Euro 5w-30 and am really happy with this oil. It is pricey though. I dump at 3,500 to 3,750.
According to this PDS that’s a year old the 5W-40 is SP.
How did you determine that the Red line is better and why do you replace so soon? I have it in my car and Red Line said 10k is acceptable, I will only go 5k since mine is sever service.
I know whet you are implying here, but tolerances do impact the allowed clearances in production.
High strung?
Implying the motor is high reving and producing a lot of power. It makes peak power before 6000 rpm, probably shifting shortly after that.
Better is just my opinion to my situation and my beliefs. I don't believe in Hyundai's sub standard choice on recommend oil choice for my driving style and use case. I get very little fuel dilution as per my very controversial Redline post. As a Hyundai owner who had a damaged motor with Hyundai's "ongoing (10 years and going) bad choice of soft piston and bearing metallurgy choice" on a 14,000 mile engine in a 2013 Elantra GT. I wanted an oil with Ester as it's polarity is metal loving, to stay on my piston skirts on a later start up, even though all late Hyundai turbos have hypereutectic pistons. I always run my car 3-4 minutes before driving it ( even in the summer) because I have seen a good # of Hyundai pistons with rock wear. I myself am not into the short piston move in modern day engines. I give it some time to start the pistons to expand as I run 23 lbs boost, even though I know throttle position = load. Hyundai turbos are hard on oil, and many Hyundai turbo owners who have had other brand turbos has noticed blacker oil sooner. (black doesn't mean bad oil) Whether it is Hyundai's tune, tolerances, or metallurgy choice, Hyundai's appears to soot up their oil faster then most. I am also hard on my turbo as many days when getting to work in the morning you can see me driving around our parking lot in circles for cool down time before shutting down. You know, the tinging exhaust sound from a blazing hot exhaust...ha ha. Redline's Ester gives me a better window into not coking up my turbo on those days. I also want to reduce wear on my cam chain/s, rails and tensioners long term. Yes, I could get more mileage on my oil, but I choose not too. I also tow a mid size boat for this sized car.
Literary horse racing metaphor
I'm going to try to run some fuel comparisons after the break-in is done. I want to compare the mpg and see if the oil is affected by dilution and/or soot. For now though... I'm having fun.
