Hey all finally got time to do a used oil analysis, engine has about 122k miles on it. I just picked this up used about 2000 miles ago so its my first oil change / uoa
Engine: 2014 Honda J35Z2 V6 3.5L with 122k miles - VCM was enabled it's whole life, i just turned it off about 500 miles ago
Oil: Presumed VRP 0W20 according to windshield sticker but will never know
As far as I know and have seen, engine does not burn oil, runs great and doesn't leak
Driving conditions: This sample was probably about 50% city and 50% highway, last owner said he barely drove it for past month so he prob had tons of stop and go. Truth be told for the last 2000 miles ive had it for, i have driven it 'hard' i dont' know the definition of hard but the engine definetly was in the 4500 rpm range daily for a little bit of time as i would merge onto the highway. however other then that i drive it normally.
I did this oil analysis from a small local lab as I was impatient, now I don't know if these labs are an anomoly, lab error, or actual engine issues but in future will run the next sample from a diff larger known lab and see how it goes.
*I also want to say i used Techron complete fuel system cleaner 3 consecutive tanks in a row. I know this is overkill but i wanted to ensure the fuel system was squeeky clean. not sure if this effected the oil analysis but wanted to put it in there incase PEA has something to do with piston ring wear. Also i stored the sample in a plastic thermos mug from the dollarstore so not sure if that leeched into the sample and effected it.
I typed out the results so its easier
Once again, 3400 ish miles on the oil. Probably VRP 0W20 in it. Not sure what type of spectrometer they use or what fancy calculation system it is but here it goes. I know some stuff looks missing but thats all i got, nothing else was checked
Iron 13
Aluminum < 2
Chromium 5
Copper < 2
Lead < 2
Molybdenum 89
Potassium 4
Silicon 11
Sodium 4
Viscosity at 40: 44
Viscosity at 100: 7.9
Fuel < 2
Nitration 5.3
TBN 5.9
Oxidation 4.4
I did some digging and for my usage, iron seems high and chromium seems too high. Maybe Iron could be high due to my 'hard' driving but idk if that would count as hard. I always made sure engine was warm and never tracked it or anything. Regardless chromium is too high, I asked the lab and they said everything is fine and if it was bad would be much worse. Fuel is not worrysome as it is under 2 they said so it probably isn't diluting I assume. Im not the best at commentating on the rest but viscosity seems fine, just TBN seems high but maybe normal for 3400 miles ish
What worries me slightly is the Iron and Chromium. Idk if the techron had much to do with it or maybe VRP is cleaning gunk off which abrased the rings? The engine runs great and now I have VCM disabled so I was just going to run the VRP 5W30 (i just put this in fresh) for however many miles you guys recommend and then run a sample at a different more well known lab and hope the metals go to baseline or lower. I think regardless when I am all done with VRP its prob going to end up being on M1 ESP 0W30 or M1 0W40
Ty for all the help everyone!
