2002 Ford Ranger Edge 3.0L 76k
I know that oil turning a darker shade or two doesn't mean the oil is spent completely. However, I normally associate that with oil that has been in service awhile. While I have read in articles online about this happening due to soot being removed via the oil, in my case it is happening in less than 1k miles into OCI.
The truck calls for 5w20, but I have been using 5w30 Castrol edge since I got the truck about a year ago with 66k on the clock. It literally looks like dark roast coffee within the first 1k miles and it got me to wondering why. Every vehicle I have owned in the past never did this regardless of miles from new to well used(170k).
Is this a sludgy motor being cleaned by synthetic oil? Or is it incomplete combustion hence the soot? My commute to work is 64 miles round trip with 25-27 miles highway and the rest city.
This is the first vehicle I have ever used Castrol synthetic in and I'm also wondering if it is the "DNA" of the oil that may be causing it.
