People suggest 7500-10,000k OCI's with a quality full synthetic. But what if you only average 6-7k a year? Should you go 18-24 months if that is what it takes to reach 7500-10k? After a long cold winter, and a long hot summer I feel the need to drain and refill again, eventhough its usually only been 3K@6 months...
