Reviews of Mobil engine oil

My ‘15 Golf Sportwagen ate a quart Mobil 1 between oil changes. Not the case for LM.

Drove it to 300k using mobile 1 ephm. Sent samples at 10k intervals and blackstone always said i could run it longer. No abnormalities. I trust the oil life monitor.

I sent a few samples from my Ecoboost 3.0 to Blackstone Laboratories at 5k miles each. Mobil 1 and Pennzoil Platinum, both used Fram ultra synthetic filters.Oil was pretty much cashed out. I couldn't imagine going any further than 5k.

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

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.

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

I go Mobil one with my Mobil one oil. I run the euro blend in my 2010 WRX because it's high miles turbo so it's 0w-40. Car seems to love it.

I live in Texas so use 10w40 Mobil 1 4t And k&n filter
