Mobil 1Ext 10/30; 11K; Lexus ES350 07

[Chuy]

Don't see too many 10/30 samplings. Actually, don't recall seeing any. Mileage was actually just over 11,700 miles with no makeup oil. Used ALS via Amazon's Wix Filter oil analysis kit.

For 11,700 miles w no make up, those are some amazing #'s. The ES350 is really easy on oil - I service a 2007 as well and just change every 5k (takes 2-3 years) with dino. Good post.

Did better than the pp in the 2.5 with half the miles. I might just go back to M1.
Thanks for posting.

That's Mobil 1 Extended, to be clear. Might jump to Valvoline Max Life at the next change to see the difference. I didn't check the oil level before the oil change; looking at the contents of my oil container, the Lexus may have been short half a quart. Will monitor it better next time.

Nothing wrong with Maxlife, but I wouldn't take it to 11k.
