is the DIY/aftermarket DS accurate and reliable? I found this one: 2007-2013 Nissan Altima 31086JA00A 31086-JA00A Genuine Nissan #31086JA00A Gauge Assy-Oil Level
Although I performed the "drain & fill" twice, 4 Qts in-and-out each time I still need to accurately authenticate the correct level. It would be nice to have a DS for future.
FYI, the drain & fill PLUS clearing the code P0776 seems to be a success. I hope its all good!!
