M1 5W30 9K miles, '06 Altima 2.5

Just thought I'd share '06 Nissan Altima - M1 5W30 9,000 mile drain interval 33,000 miles on engine M1 Extended Performance oil filter. Notes from Blackstone: It looks like the sodium we found last time was from an additive in an oil run in the past. Sodium has all but disappeared in this sample and wear looks great even after the long oil run. We see no reason not to extend your next oil ~11,000 miles as nicely as your engine is wearing. The sample was free of harmful contaminates and the viscosity of the oil read normally. Nissan makes some nice engines but yours is doing far better than most that we've seen. You must be taking good care of your Altima.

That's not M1 UOA, there isn't enough iron wear. You sure you didn't forget another 0 in the iron?? LOL, J/K.....obviously this oil is doing well in your Altima. How long was this oil in your rig and I presume you do a lot of highway driving?

I used the EP formula in the prior run before this one. The numbers didn't look much different but there was 3.5 TBN left after 6,700 miles. They both seem to be good oils for my altima so I'll go with the cheaper between EP and regular M1 for now. To answer the driving question, I live in a fairly small area and do not deal with big city traffic. I think I drove the 9K miles in about 8 months.

Looks good. A bit suprised at the shearing w/o a problem with fuel. Usually, M1 holds a viscosity above 9.5cst, even on long drains.

Nice wear numbers. M1 5-30 is in my 07 Focus at this time with 8000 miles, will be switching to EP at next OC.The M1 oils do a great job in your engine.

Not bad at all I got 5 quarts of mobil one as a gift running it with a pure one filter in my rsx-s right now. I was worried but looking at these numbers I think ill be ok for 4k
