I have always changed the oil in my personal and company vehicles based on oil color. The units that mostly see around town driving seem to have the oil get to the darker tan by 3,000 to 4,000 miles. Our hiway units sometimes go to 7,000 and maybe even 8,000 miles. This is for a little older units (typically pre-2012) and nothing gets the synthetic stuff. The last company van we sold (2003 3.8 Grand Caravan) had 240,000 miles. Went through 2 trannies due to the towing aspect, but the engine did no down time.

There may be circumstances where 10,000 miles between oil changes is acceptable. But for many (maybe most) vehicles that see significant around town use, I feel that 10,000 is often, too little, too late. If for no other reason other than the dirt, debris, moisture, and acids that can build up.

I agree with the medium to dark tan color as the key indicator.

When the oil light comes on, change the oil. They say his oil change light came on and he didn't change it. If you don't have time to change it right away at least be smart enough to turn the key on, floor and release the gas pedal three times, and turn the key off. That will tell the computer that you changed the oil.

Sooooooooo, one size fits all? Every driving situation and every environment is the same? That may be a good recommendation for those that know nothing about their vehicle, but may not be the end-all, be-all for those that do understand something about their vehicle.

And let's face it, the auto manufacturers and oil slingers have mixed loyalties on this subject. Their own economics play a role in their recommendations. That situation is most evident when you look at the SRT oil recommendations.

OK I will say it.
Toss on an LS and a 700R4 wire it up fire it up done.
