Oil on the dipstick - does lighter mean it's not cleaning? Or does it mean I have a clean engine?
After dumping Next Gen after 4200 miles, it was pitch black. Dark as ever. Put in my Mobil Super Syn, took a long trip, after 1,500 miles it's still a wonderful golden color on the dipstick.
What does the color mean, if anything, on the dipstick?
