2002 Ford Ranger Edge 3.0L 67k
So my ranger that I have made quite a few threads about lately is running much better now after having replaced bad plug wires and a coil pack. Went ahead and replaced the serp belt and tensioner as well as the idler pulley.
The truck had Castrol conventional 5w-20 and a purolator filter from a quick lube joint when I bought it from previous owner. First thing I did was changed oil and filter to Castrol Edge 5w-30 and a fram xg3600.
How long should I run this OCI before changing it again if I'm wanting to clean the motor internally? I know it will take more than one change to see most if any results.
Do I leave the CE in it for a full 5k then dump it or sooner? What do you guys think? I do want to do a black stone UOA but I think doing one on a "cleaning" OCI would be pointless because of possible contamination from prior conventional oils.
