Every 3k?

 

While the oil life monitor seems to suggest I could go 10K, I change mine at 5K intervals.

 

Ok thanks. I also wanted to ask, is it bad that my oil is brownish yellow? Does the color mean anything? Like if it's black, yellow, or brown?

 

Mine is fairly dark when I change it. Not black, but dark.

 

i change every 5 or 6k. i use moblie 1 or royal purple

 

If you use full Synthetic and don't do track, autox or strip driving you can easily go 7500 miles between changes. Just make sure you use a filter rated for this change interval.

 

I use Amsoil SS every 8K or 1 year whichever comes first.

 

I use mine as a daily driver, so I change it every 6 months. Usually rack up about 5k in that time.

 

Me too.

 

GT? (8 quarts) or V6? (6quarts). A lot of short trips?

 

Just looking at color means pretty much zero when it comes to the health of your oil. If you really want to know how much life your oil has, take a sample and send it off to Blackstone for analysis. http://www.blackstone-labs.com/

I change my oil 3-4x per year and do the analysis every other oil change. The longest interval I've had analyze was 10,000 miles and the sample came back still well within normal wear, with a recommendation that I could go as long as 12,000 miles easily. This is using Castrol Edge w/ Syntec 5W-20. My usual interval is 7,500 or 4 months because I drive this thing a lot - currently at 114k+. If you want to see the last analysis I had done, which also includes all the previous data for comparison, check this link: https://drive.google.com/file/d/0B7I...ew?usp=sharing

The oil life monitor is very accurate and perfectly fine to go by. Ford's not really in the business of putting systems in their cars that lead to engine problems down the road, which is why I don't understand how many guys ignore it and think they know better.

 

Whats the deal with the high Boron level, Kyle?

 

Ha. No idea. I don't pretend to know what all the chemicals mean but count on the analysis from Blackstone to guide me! They didn't call it out as an issue so I don't know!

 

Boron is added to reduce friction. It has been added to motor oil since the early 90's
