This is actually for my wife's 2001 Maxima.
I'm going to do the next oil change. She's been taking it to the dealership since we bought the car and they've been just using regular dino oil.
The car has 55,000 miles on it. Will I harm anything by putting in Mobil1 synthetic?
Also, I've read some people saying you should do a synth/dino blend for the first time, others say use something like Amsoil's flush first before putting in the synthetic oil.
What's you guys' take on this? Has anyone made the switch at or around this mileage?
