Car was broke in on Valvoline conventional 5w20 with very frequent drains and very hard break in. Filtration was OEM. 95% highway with average speeds at 70mph and RPM at 3100. Commuting only at 40 miles to 60 miles one way depending on route. Regardless of route still 95% highway speeds. Lab was Dyson. If the values of the analysis were 0 I have not included them here.

Engine looks very nice especially considering it is barely broken in.

Is this a DI engine? Fuel percentage seems high for interstate drving as well as the low flashpoint and somewhat low TBN for 3k miles. Plus the additives seem low, almost like the problems that Blackstone Labs has running high mileage oils for their UOA.
 
3.6 TBN....why are you only doing 3K? Is that what Kia recommends?

IMO...5K should be easy on the oil your using....its a waste if you go less than that.... with 95% highway driving....whch is very easy on the oil.
 
I wouldn't give them $2 a quart for that, PAO or not. It's exceedingly lame, IMO. PYB, MS5K and others are better for much less money.
 
2.0 or 2.4?
any oil consumption?

Highway driving should let you push the OCI to 7.5k.

Thin oil = MPG.

Wear is only 10ppm and engine is still young. Nothing wrong with the oil here.

Fuel dilution is too high! If all highway driving, engine might benefit from leaning out. I bet it runs pig rich to keep emissions system happy.

If you stick with Amtecol, try their 0w30 or 5w30. The extra point in visc will make up for the fuel.

Short OCI was the longest so far to allow for break in trending. Car is port injected. I got this oil for about 5$/qrt and was looking to see how a majority PAO would hold up and how it would affect mpg. MPG is up about 8% fwiw.


Mileage increase may be from the powertrain wearing in and not from the oil. I agree with the visc, flash point and low tbn (though fuel would help explain tbn).
 
This one is the 2.0L. I’m guessing that it is the ECU running rich to help light off the cats that’s causing the fuel. I’m currently looking to lean it out so I can extend the OCI. I may experiment with heavier oils, but I have my current fill of Amtecol and one more OCI along with some Edge 5w20 I got free so I will add to that stash for 3 OCIs total. I will keep doing UOAs for giggles. Don’t really care too much about running this thing optimally, rather its just a hobby until I can figure out what high performance transportation I want next.

This PAO oil has a virgin KV100 of 7.7cSt. I suspect they're using higher natural VI base oils and less VII's to achieve the lowish KV100 spec'.
 
The fuel dilution is killing the oil. I would switch to something a bit more resilient.

You could easily run Renewable Lubricants' 0w20 for 5k or longer. It handles fuel dilution well.
 
Looking at the shear rate of the oil according to VOA it held up pretty well it appears actually. While RLI is quite revolutionary my experience with it hasnt been superior. While not looking back at previous RLI UOAs of mine I seem to recall them shearing at about 10-15% in my applications.
