PU 5/30 4300m | 33.3K m 2010 370Z VQ37VHR

[bvl]

Lower mile (6mo for warranty) winter change. Car sat for weeks at a time but got plenty of 100m runs once the salt was gone. Metals back down to normal from the elevated spot on last change.

Unfortunately I only have 2 batches of PU left in my stash, so 2015 will mean either new PU or something else.

WOW, very consistant on all 3 in each catigory.
Why the shorter OCI on this one?

Stick with the Ultra. Looks like the perfect oil for your Z!

Warranty purposes only. I have a 7/72 with Nissan which Runs to 4/2016 IIRC. They have a ridiculous 3m/3750 Schedule 1, I run 6m/7500 schedule 2. Plenty of my miles are 100m HW commutes, they can't say boo.

My preference would be 7500-10K and 1y intervals with PU or similar, the oil and car appear to get along just fine. Just too bad PU is dead. Maybe I just use my stash for the summer OCIs of up to 7500 mi, and use PP for the shorter winter run.

Wear metal are same or more as the mileage 4.5K is less than prev OCI. Looks fine though.
