This is a UOA from my daily driver, a '96 Nissan Maxima with about 242k miles. Engine is Nissan's first generation VQ V6 engine (VQ30DE). I drive this car primarily to work and back, 70 mile total commute. 80% highway, and 20% city. I put about 20k per year on the car; this OCI was from Sept. 30th of last year, and I changed it at the time of UOA. Oil filter used was a Hastings LF240 (equivalent to PH7317 in Fram-speak). Oil is Pennzoil Ultra Platinum 0w-40, the one branded with Dodge's SRT logo. I bought this stuff for $1 a quart during the late-year Autozone closeout. There is a VOA on the forum somewhere. I'm fairly impressed with the results aside from the lead which is a little perplexing. I can think of nothing that would cause a spike in lead-- the engine is running fine, no maintenance issues or anything of the sort. No hard driving or short trips. Only thing I can think of is that this OCI ran straight through the dead of winter, and it was a cold one this year with a lot of 0F degree days. Curious to hear thoughts and comments.
