How are you judging your oil changes?

[kirbybc12]

I changed my oil last around 12,000 when I first got the truck, so if I go by the 5,000 rule I'm overdue by about a thousand. How good are the sensors at detecting oil quality? I'm not sure whether to change my oil now or wait until my truck tells me.

My first 2 oil changes I did at 5,000 miles and the 3rd one I waited till the oil change light came on.It came on aout 6700 miles.

With the emissions equipment on the newer trucks, the general recommendation is to change oil every 5K miles and/or to submit oil samples to Blackstone labs (or others) for oil analysis.

Ford has a you tube video saying that your truck will tell you when it's time to change. I checked mine at 7k miles and it still said "Oil OK". At 7,200 miles it came on.

Maybe I shouldn't have checked it so soon.

The sensors don't check oil quality...they know nothing of your oil status. All they do is calculate your change interval based on your driving habits and mileage since the last reset. So if you put an expensive synthetic oil in your engine, or a cheap conventional oil, your computer knows no difference.

If you're not the type to conduct UOAs and monitor your oil, I'd stick with the computer intervals when using high end oils, and stick with 5K intervals for low end oils. But that's just me.

I stick with 3k intervals with mine...just cuz the injector depend on it...plus I'm old school so I say 3k

HEUI Injectors ended with the 6.0 so in the 6.7 section it is a rather moot point to be considering in regards to oil change intervals.

I run full synthetic (Rotella or Duron) and the truck is deleted so I change the oil when the truck tells me.

As I stated at the end of my post I would change it at 3k ...meaning weather it's a 6.0 a 6.4 a 6.7 or 7.3

Not to change the subject but what weight oil are you guys running in synthetic?
