UOA is from my '96 Nissan Maxima GLE V6 auto (VQ30DE). Oil used was Castrol Edge Extended Protection 5w-20, ran from January to April, just shy of 6k miles. Added 1/2 quart of top-up, oil filter used was a Purolator Gold.
Nothing unusual worth nothing about this OCI other than oil consumption went up a bit. (My last UOAs were a few thousand miles longer and I did not need any top up.)
This OCI was shorter than I usually do; with the weather getting into the 80's I was a bit apprehensive about keeping the 5w-20 in there. I did notice a decrease in wear metals overall, I might stick with 7500 mile intervals to see if the lead stays low, as lead was flagged in my first UOA which had a 10k interval.
The OCI before this one, I didn't get a UOA for, so there's a gap in the mileage. The previous UOA before this was using Castrol Edge 5w-50, the one before that was Pennzoil Ultra Platinum 0w-40 SRT branded oil. I changed the oil to Chevron Delo 5w-40 for the next run.
Was pleased with the UOA results, so much so that I gave the car a thorough wash and wax for a reward!
