Hello,
I have my Maxima 09 for a year now, it had 80k miles at that time and now sitting at 91K miles. The car, from maintenance records, was meticulously maintained by the original only owner who had it before me (a lady) and had her oil and filter changed around every 4k miles exclusively at a Nissan dealership using conventional Nissan 5w30. When I got it I also had the CVT fluid drain and refill, did a coolant flush at Nissan using the Nissan green coolant 50/50. Car is very well maintained and very clean.
My first oil change 3 months after purchase was with a synthetic Mobil 1 extended performance 5w30 then the last 2 OCI were with Pennzoil UP 5w30 and Nissan oil filters.
Now since it's pretty cold here, morning temperature ranging from 30F to 20F car takes a long time to warm up, car is not kept at a garage, I sit boringly in a cold car for a whole 5 to 8 minutes sometimes waiting for the thing to warm up, sometimes I have to leave faster, and for maybe at least 3 to 4 miles till I see temp gauge in the normal operating position. I try to be very calm with the car til it heats up (which is REAL PITA in morning crazy traffic). Car (engine and/or transmission doesn't feel and sound right until it heats up), I log up real live data from ECU through my OBDII port, once car is warmed up it sits stable at 195F and oil around 180F-190F when fully warmed up and stays there, can not really blame the thermostat for the issue.
Is this normal? should I think about switch to 0w30 oil?
Thanks
