Good morning everyone,
Just got the results back from a UOA I did on my 2011 Kia Sorento. I used ALS Tribology for a change. It's available through NAPA auto for $14.99 here in Tucson, including TBN, so quite a bit less expensive than Blackstone.
On to the actual numbers. I'm a little concerned with Al 16 and Silicon 33. It may just be from the engine still breaking in. We'll see. I still have the original air filter in (undisturbed). I plan on putting in a filterminder to minimize changing/messing with the air filter. I will check the duct work for leaks, but I am skeptical I will find any on a new vehicle.
I am constantly impressed with PYB. No real change in the KV100 viscosity (8.4 to 8.3) with a 3.4 TBN, although I added approximately 3/4 quart over the OCI.
I switched to Mobil 1 0W-20 AFE when I changed the oil. I am not sure I need it with the TBN retention of PYB over the 7500 mile OCI which is the maximum interval I can use while under warranty.
I know that PYB would last for at least 2K more miles. I am thinking about trying Motorcraft SN 5W-20 syn-blend since I have read that it is now 60% Group 3 (Korean Super-S) or the Mobil Super 5000 which may very well last close to 7500 miles here in a warm climate.
Or I may just go back to PYB as it appears to be the gold standard in conventional oils. In spite of the Mobil 1 being 0W-20 I honestly believe the PYB 5W-20 Group II+ conventional with the high moly content actually is smoother and delivers comparable mileage even in ~30 degree mornings we've had here lately.
Anyway, any comments or suggestions are always appreciated.
P.S. I think QSUD, PP, or even PU 5W-20 would be fantastic in this engine if I decided to throw caution to the wind regarding the warranty and extend the OCI 50% to 11250 miles to start. I am on the fence about whether to stay with a premium conventional for 7500 miles or go this route. Time will tell. )
P.P.S. Or should I switch back to a good conventional oil and run a shorter interval (3-5K miles) one time and "flush" the engine and see if I can reduce that Al level before going to 7500+ mile OCIs?
Thanks,
Gary
