Ask TundraHQ: My 2007 Tundra Is Burning Oil – Is That Normal?
A reader writes:
I have a 2007 Tundra with the 5.7 that I purchased brand new in the spring of ’07. The truck has ~64k miles, has been serviced at the dealership since it was new, and has not been abused. I’ve been using Mobil 1, changing the oil every 10k miles. I noticed when checking the oil before my 60k service that it was down about 3/4 of a quart on the dip stick. The dealership’s service department said they have never heard of a Tundra using oil, especially at only 60k miles. Is this normal, or is something wrong?
Short answer: There could be something wrong, but more likely than not everything is fine. Here’s some more detail.
Chevy/GMC AFM Cylinder Deactivation Excessive Oil Consumption – Ongoing
