Hey everyone, recently i realised my dipstick's oil submerged area, is blackish in color.
I cleaned it well, oil changed, it is still blackish in color.
I gather it could be a metal material reaction to something.
I have never encountered dipsticks to be black in color on the lower portion.
Probably heat? Or probably because of my adding of Liqui-Moly Ceratec.
Anybody has this problem?
"I gather it could be a metal material reaction to something." - Probably.
"Probably heat?" probably not heat alone.
"Or probably because of my adding of Liqui-Moly Ceratec." - Probably, though I've no experience with that.
Assuming you've got no history of gross overheating (this an aircooled engine?) you could experiment, if you care enough.
Get two small containers, (small bottles or cans, bottles better) and two pieces of bare, degreased steel (nails, or maybe pins or needles probably convenient. Alloy won't be the same but probably close enough)
Put a little treated/untreated oil in each bottle with a steel thing and heat both in a double boiler daily for a week or until you get bored. Don't cap the bottles. If the treated oil turns the pin/needle/nail black, and the control oil doesn't, you have your suspect.
