Color means virtually nothing.

What where the previous OCIs? How many miles on this OCI?

Was using Mobil 1 changing every 6 to 7000km.....This was a used engine (100 000km) that was put in the car 2 years ago since the head gaskets were wrecked... Only 2 oils this motor has seen since in my car was Mobil 1, Mobil 1 EP and PP 7000km is the MOST I have ever gone...scared to go more!!!!

7000km should be about nothing for PP or M1, as long as you can keep that motor topped up. Try 10000km.
