Started using top tier gas
Oil has gone black after 1000 miles since the car was new
Oil stays clean on the dipstick now
Same brand of oil ready for its 3rd oil change since switching to better gas
I guess it is cleaner running fuel
 
All my past and current H/K products turn the oil dark after about 1000 miles. What has lessened is the tailpipe soot on the Santa Fe Sport 2.0T. No idea why.
