True, Also in my opinion the frequency of oil changes not only depends on driving style (ie. normal v/s heavy stop-n-go but also on the quality of oil filter used.

Took my truck to a stop-n-lube place they used traditional oil and in less than 3k my oil was black. All I do is normal driving nothing extreme. I think they must have used a poor oil filter. Oil will be dark but it shouldn't be completely black in less than 3k

This time I changed it myself using MC 5-20W synth blend and a Fram tough guard which is supposed to filter ...

• Uses a higher level of synthetic media to give 6X MORE engine protection than the average of leading economy oil filters
• Unsurpassed 99% Dirt Trapping Efficiency
• Screen-over bypass valve provides a second layer of protection against larger dirt particles
• Silicone anti-drainback valve holds a reserve of oil in the filter to help protect the engine during cold start-ups
