Hey All,
I just recieved my first UOA today on my '05 Nissan Altima with the 3.5L VQ engine; I'm still awaiting Terry's analysis.
I really have no interest at this point in extended drain intervals (warranty, you know, and dino's cheap). I was just curious as to how my car was doing, as I've heard these engines can be hard on oil, and I wanted to see how the Havoline would hold up.
I primarily drive short trips around town - about 12 miles to work and back, with lots of stop and go driving. I do take about 1-2 trips/week that are primarily highway miles (60 miles round-trip).
I normally change oil every 3,000 - 3,500 miles. I use a Purolator PureONE filter, Havoline 5W30 (SM), and I still have in the OEM air filter. I also added 6oz of SuperTech injector cleaner at the last oil change.
Here are the stats:
MILES ON OIL - 2853
MILES ON ENGINE - 11890
*First number is current value, and the second number is the universal average*
Aluminum 6 - 3
Chromium 1 - 1
Iron 7 - 11
Copper 11 - 7
Lead 2 - 5
Tin 0 - 1
Molybdenum 407 - 73
Nickel 0 - 0
Manganese 1 - 1
Silver 0 - 0
Titanium 0 - 0
Potassium 1 - 1
Boron 27 - 74
Silicon 17 - 11
Sodium 3 - 5
Calcium 1565 - 2379
Magnesium 24 - 122
Phosphorous 635 - 728
Zinc 930 - 868
Barium 0 - 0
SUS VISCOSITY @ 210 °F:
Should Be 56-62, Actual = 56.4
FLASHPOINT IN °F:
Should Be > 365, Actual = 375
FUEL %:
Should Be < 1.0%, Actual = < 0.5
ANTIFREEZE %:
Should Be 0, Actual = 0
WATER %:
Should Be < 0.1%, Actual = 0
INSOLUBLES:
Should Be < 0.6%, Actual = 0.2
TBN = 2.9
To my eyes this looks OK, but I want to hear from everyone what they think. Admittedly, I'm quite the novice here.
