I just received my second oil analysis from Wix (I wanted to try the Wix service and compare it to Blackstone, needless to say I will be using Blackstone from now on).
Anyway, this report is from my wife's 2015 Nissan Rogue. At this oil change, I switched the oil over to Liquimoly Special-Tec Ow20 from Pennzoil Platinum Pure Plus 0w20 (with a K&N Gold oil filter). From my research, it seems like Liquimoly is highly regarded, so I wanted to see if it was worth the higher price tag versus the Pennzoil. The first image depicts the most recent analysis with the Liquimoly:
This next picture is of our initial Wix oil analysis from the Pennzoil Platinum:
My concern is the amount of sodium and potassium in the Liquimoly. While it appears that there are less wear metals in the Liquimoly, I wonder if the increased sodium and potassium are either additives in the LM or if this is an early sign of coolant leaks/oil contamination (even though the lab lists no coolant in the oil)? I also noted less additives overall in the Liquimoly, specifically molybdenum. How would you take the results of these samples? Should I stick the LM or switch back to the Pennzoil? We're running 5k intervals for the Rogue, only because the warranty we purchased specifies that the manufacturer's maintenance intervals are to be followed exactly as printed in the owner's manual otherwise the warranty is void. The vehicle is a former rental, we purchased it used in August 2016, roughly 32k miles and now approaching 50k.
Also as you may or may not have noticed, the most recent (June 2017) Wix analysis incorrectly lists the oil as Pennzoil even though it should be listed as Liquimoly. One of my gripes with the Wix service is that on the initial analysis, they recorded the vehicle as a 2016 Rogue, and now on the second analysis they listed the incorrect oil. Also, for some reason, they treated the second sample as an entirely new sample from a different vehicle, thus I had to submit screen snips of both reports to compare both reports. Blackstone might be a bit pricier, but for at least for me they're consistent with their reporting.
