Engine oil Mobil or PENNZOIL

Valvoline Restore & Protect is apparently amazing when it comes to desludging engines, and Mobil 1 also has some knockoff that claims the same.

Synthetic oil change is now $125 at the stealership so Ibu my own 0/50 Penzoil and a high quality filter every year, and vacuum out the Hybrid Traction battery filter myself

Looking over this old post -- an update: I have since migrated to M1 ESPx2 in 0-20. The price has stabilized at $25gallon, and that made all the difference in the world to me, and is allowing me to reduce my OCI's to 5kish.

I use mobil one ESP 5-30

Mine has had Mobil 1 Extended Performance 0w20 its entire life (aside from the factory fill) and I've had exactly zero oil consumption or lubrication related issues. It still gets nearly the same fuel economy and is as responsive and smooth as when I bought it, no matter if it's blasting up a steep mountain or baking in the heat of summer traffic.

0-20 pennsoil synthetic with a wix or napa filter

Every 4k-4500 miles with a Mobil 1 5w30-5w40 mix and some liquimoly oil treatment.

Unless you are tracking the car you aren\u2019t going to see a difference. I use Pennzoil ultra platinum and a wix filter on my daily\u2019s.

All 4 of my Subarus have serious consumption problems with Mobil 1. On my current 15 outback I tried liquid moly and it consumed it. I went back to the Subaru dealer parts department and so far 1200 miles the level is still full.

Pennzoil UP was on a sale and I bought 15 quarts, my Sierra dropped a lifter within 200 miles of the OC and switch, related, no way, will I ever use Pennzoil UP again, no way.
