Wife has a 17 Nissan Sentra. Vehicle calls for 0w20. Been using m1 EP 0w20 since she got the car which had 2k miles. Her car now has 100k. Every oil change (but the last one) has been sent for oil analysis. Never have gotten a bad report.
About to do spark plugs next weekend. Not sure how the plugs look as of yet. But car has been running fine so I am guessing the plugs will show normal wear.
Question is, since her car is out of warranty, could I bump up the viscosity to 5w30? I would assume the car would run a bit more smoothly but loose a bit of mpg.
We live in southern AZ.
