I have pretty much finished my experiement. I have noticed in prior years that engine oil will oxidize quicker in the winter months than in the summer months. I live on the west coast of British Columbia, and from about November 11 to the middle of April, it rains. But when I talk about rain, I mean that it rains for at least 60 to 70 days in a row. The bulk of my driving is on the highway, so my car is consistantly ingesting spray, mist from other cars on the highway. I have noticed that the oil becomes very dark very quickly. At about the 5000 km mark, the oil is dark, and I assume that it has been oxidized by the water that is inherently absorbed by the oil from day to day driving. And to mention, I am a religious Mobil 1 user.
In the summer months, the weather is far more dry, and my oil stays far more cleaner for much longer, thus extending my OCI.
Has anyone else experienced this. I know that some people live in humid climates. But I am refering to not only humid climates, but the constant spray and mist that a vehicle injests in very wet and humid areas.
Please weigh in.
