I have several oil changes of Castrol Edge, PP, GC, and a case of PYB however this oil change I cleaned up my scattered, and half bottles of oil stash. I have picked up oil on sale dirt cheap in couple quarts. My current fill is 2 quarts Havoline Deposit Shield 5w-20, partial Quart of GC, Quart of Castrol semi-synthetic 10w30, sand the rest Castrol High Mileage 5w30. This will be a shorter than normal OCI ( normal 7500 OCI on conventional) run back t back on a K&N oil filter (second run on this filter..been running filter two OCI's per owners manual on conventional). I'm not sure how far to run this oil maybe 4k-5k.
I'm sure many of us get in this situation ending up with stray quarts/partial quarts of oil. I stand back in awe however when I have perfectly good synthetic, and filters yet I chose to clean up my stray quart oil stash. The reason I decided to do it this time was to get my second run on the oil filter, it's summer time so the other than 5w-20 will be a good time to run this oil... and I guess I'm just a cheapo !!
