So my 2006 is350 has just under 68k miles. I've been using Mobil 1 5w-30 fully synthetic oil. For some odd reason I get this feeling that its comsuming oil. It very little I must say and I'm not even sure if its just because I'm using 6.7 qts. Folks on here say they use 7 qts of oil. So I'm just wondering if I should switch to Mobil 1 5w-30 fully synthetic high mileage.

No need! Your car just barely broken-in. I have over 120k miles and still using Synthetic 5w30.

Its normal to burn a qt of oil every oil change.

At what interval do you do your oil changes?

Lexus will tell you that if your motor burns that much...but it is not normal.

I change my oil every 5k miles or every 6 months which ever occur first.

Engine oil consumption
- The amount of engine oil consumed depends on the oil viscosity, the quality of
the oil and the way the vehicle is driven.
- More oil is consumed under driving conditions such as high speeds and frequent acceleration and deceleration.
- A new engine consumes more oil.
- When judging the amount of oil consumption, keep in mind that the oil may
have become diluted, making it difficult to judge the true level accurately.
- Oil consumption:Max.1.1qt./600miles, 0.9lmp.qt./600miles(1.0Lper1000 km)
- If you consume more than 1.1qt.(1.0L,0.9lmp.qt.) every600miles(1000km), contact your Lexus dealer.
