My 1zzfe engine has just over 10k miles. This is its first winter and my first time using M1 0W-30. Previously I had done a fall 3500 mile run of GC and before that a summer go (3500 miles) of M1 5W-30. In each of these OCIs there was very little consumption. However after about 1500 miles of the M1 0W-30 I am down almost half a quart. This oil went in on November 11th and the car has encountered lots of snow and colder temps. What do you think?
