I'm not too sure if 5000 miles is a good idea with a car doing short trips. Nissan calls for 0w20 and to maintain warranty I would run a 50/50 0w20 and 5w30 mix. You will have a receipt for the 0w20. Get a jug of both. 4 quarts puts it at the top line on the dipstick. Also, if running the Nissan...

I may go back to the Restore and Protect after I see what happens with the Pennzoil Ultra. The oil life monitor is showing 10k intervals which is crazy.

That was the factory fill.

Here's the results from the 3rd oil sample on a 2025 Nissan Sentra SV 2.0 DGI. At that time, I didn’t change the oil until I got the results back. The new fill after receiving results consisted of Pennzoil Ultra Platinum 0W-20 and 5W-30 (50/50) along with a Microguard Select MSL51358 oil filter...

Fuel dilution is the only thing I’m concerned about.

Here's the results from the second oil change on the 2025 Nissan Sentra SV 2.0 DGI. The new fill consisted of Valvoline Restore and Protect 0W-20 along with a Microguard Select MSL51358 oil filter. I'm hoping Valvoline Restore and Protect can help with intake valve deposits. I elected to stop...

That's what I keep hearing. Look at the drop in silicon from the Subaru BRZ I posted recently.

I believe so. Look at the Subaru BRZ analysis under my user name.

Everything is good there! I always double check that stuff.

I was thinking of switching over the restore and protect to keep everything clean the next time around.

First oil change and analysis. Lots of chatter on the Net about RTV issues and break-in metals. Cut the filter open and saw nothing to be alarmed about. I'm not certain about 0W20 in a high rpm motor but that's another discussion. The oil change consisted of Valvoline Extended Protection 0w20...

Valvoline Extended Protection 0w20.

To raise the viscosity slightly. Experimenting. I will post results next change.

Probably 3,000 miles.

Here's the results from the second oil change on the 2025 Subaru BRZ. The new fill consisted of the same Valvoline Extended Protection 0w20 and 5W-30 (50/50 mix) along with the Subaru 15208AA170 oil filter (Japan). May consider going to Restore and Protect in future.
