How Many Miles Between Oil Changes

[ExpeditionAndy]

I know what the owners manual says but what interval are most of you using on your expeditions. For the last 20 years I have been driving Mercedes cars (new and old) and I got used to the 10,000 mile oil change interval. What is best for the Fords with the Triton 5.4 engines?

I had one friend say to change it every 3000 miles but that seemed old school, so what is the consensus of opinion here?

I go 6,000 miles with synthetic oil

 

[alaskanexpy]

i go 5-7k on mobile 1 synthetic and motorcraft filter.

I'm going about 5K between changes using whatever the dealer does for me (great deal there since bought the vehicle there). They say it's a synthetic blend.

 

[tallsville]

I usually go 5-6k on conventional(they usually put 5w-20). I've went 11k between oil changes one time. I wouldn't recommend that though.

I use a high mileage synthetic and go about 5-7k between changes depending on how much I'm driving for work. But on this last one I've got about 9k racked up. Like Tallsville said though, I wouldn't recommend it.

I go about 5k between oil changes. I figure old school was 3k and manual says 7k, if I remember right. So 5k is a middle of the road. I think 3k was put in place by the oil companies and oil change stores. Engines, filters and oil have changed alot since the oil 3000 mile standard was set.

I'm probably the odd-guy out, but every 3K since the oil is used to lube the supercharger and that is Vortech's periodicity.

4k. Straight conventional 5w-30

every 5k w/motorcraft synthetic blend & filter until recently, at 125k 2003 5.4, I did not like this oil, seems with the higher mileage nearing the 5k the oil was extremely dirty, switched to full synthetic... will compare the difference and change the oil around the same interval.

I'm running mine up to a premium synthetic with a LONG OCI. So this time is 7,500. The next is 10k. This is on full synthetic.

I'm very wary of anything called synthetic blend. There is no actual standard for what makes a synthetic blend. So it can be 99.99% group II conventional and one drop of Group IV synthetic.

 

[KWT2000]

I'm seeing filters rated up 15,000 miles. Seems crazy to go that far to me but the new diesels are going 50k so maybe not

The Mercedes regularly went 10,000 miles between oil changes, but then they held 8 to 9 quarts of oil.

7K with Mobil1 and a WIX or Motorcraft filter.

One of the things I've been toying with is taking oil samples and sending to a lab for testing. We do it with our diesel gensets at work and the info they come back with is awesome. I've found that you can extend the life of your oil by knowing how it's holding up. In fact, there are many who just change their filters and top off the oil in their heavy equipment. What they found was the new oil added to top off had enough agents to revitalize the old oil.

I do this on my semi with bypass filtration my avg oil change is 370,000 miles with samples at 30,000 with filter changes

I do this with my John Deere lawn tractor - top off the oil and change the filter once every 4 or 5 years.

 

[dadamaja]
