rolling up on 7k right now and was planning on changing it tomorrow since my mileage would be 137,500 -- put me back on schedule so my next one would be an even 145k @ 7500.

got to thinking though, i might be able to stretch it out to 10k. maybe? I just added another 1/2 quart to bring me back up to the "safe" range (cauz i had to go get some hay bales about 40 miles away).

i like even numbers ... easier to remember.

06 expedition, 5.4. almost exclusively highway miles. not much towing. only a 250 mile trip with my 2000 lbs car trailer (empty one way, bale spear on the way back) and a 80 mile trip to go get some hay bales (empty down, 5000lbs(ish) total on the way back). i drive fairly easy and its 20ish miles one way to work.

just looking for opinions. i've got enough top-off oil to get to the 10k mark (9500 actual to put me back on schedule @ 140k).

in hindsight, for the extra 4 bucks i should have just bought the Edge Gold, which i would probably do next time if i really want to do 10k.
 
Which grade of Edge? The 0w-30 and 0w-40 Euro grades can definitely do 10K miles and more since they carry official long life manufacturer approvals.

But with mostly hwy miles, even the non-Euro grades should be able to handle 10K miles.
 
an consensus on BITOG?!?!?

one thing I forgot to add was I'm using a NAPA Gold filter. My gut tells me that it should be fine, but in the back of my mind I'm wishing I had a Bosch D+ for the extended OCI.

but then I go back 10 years ago when I was driving 160+ miles/day and I would run Syntec for 10-12k with a motorcraft filter (3 months, regardless of miles) in my 94 escort.

the only thing bothering me is 10k is twice the recommended OCI for the vehicle. but, I do have to add occasionally. so far I've added 1.5 qts total. I'm thinking if I add the other 1/2 qt, it will carry me to the 10k mark.

137,500 and 145,000 are still not evenly divisible by your anticipated 7500 mile OCI. That would be 142,500 and 150,000.

With that much top off, you can likely run it out to the 142,500 and put that OCD at ease.
 
You don't have to go so expensive for highway miles. I'm pretty sure supertech synthetic or any house brand synthetic would do what you want.

you are saying the Napa Gold is better than the Bosch Distance+?!?!?

that's the first time I've heard that claim.

Could be, but I thought the specs on the D+ were on par with the Fram Ultra.

ok .. I've checked the math several times now ...

137,500 + 7,500 = 145,000

I changed it last at 130,000 (actually 130,500ish) and I'm currently at 137,500(ish) so changing it now gets me back to where I'd be at an easy-to-remember interval @145k.

but 140k is easier to remember still

then 150, 160, 170 ... and so on and so on .... or so I hope.

that's the other part of the equation too ... I've got 3 years left on the note, so at 25k/year it will have 180k+ on it at the end of the note if I don't get it paid off early. I'm hoping to get another 5+ years out of it before replacing it.

I'm just not sure I can make myself do it. the oil looks great in the engine. not dark at all .... if this were the EP, I don't think I'd be as gunshy

I was going to change it and do a UOA at 7500 (actually 7000) to see what I have ... but if I go to 10k and it turns to be too long, what would I expect to see in the UOA?

Low TBN and/or high metals?

surely one OCI that was longer than it should be won't kill the poor thing, will it? If it was a long enough OCI to kill the engine, there would be other signs, yes? like bad noises or really black oil?

without a UOA, how does one know that he should have changed it sooner, or how does one know he should change it very soon?
 
If it's been in there too long: TAN exceeding TBN, and possibly higher solids.

One slightly longer OCI won't kill it. But again, 10K miles given your driving pattern is not long at all, IMO. Is this engine known for being particularly hard on oil?

No way to tell, really.

That report is outdated since Castrol changed the formula for the black bottle. Newer formula has 6ppm of Titanium. Possibly lower TBN.

If I were OP I would do a UOA sample at 8K w/ TBN test and determine if can go to 10K.

What leads you to think the newer formula may have lower TBN?

I did a UOA on the new formula black bottle 0W20 for 5,000mi and 6 months and the TBN was at 2.8. If it had a higher TBN the UOA TBN should be higher. I'm just assuming though.

Understood.

The only thing I'll throw out there is that the first time you run a new oil, you often notice quicker TBN depletion, presumably due to additive clash with whatever was left in the engine from the previous oil. That's why I never do a UOA the first time I run a new oil.

You also pointed out your driving puts you in the severe service category, which is very different from the OP's driving patterns, and that has impact on the oil as well. This is why I don't do extended OCIs in my 530i.
