Castrol Edge Black Bottle for 10K?

I think the Bosch is the same as a PureOne which I would put below a Napa Gold, but I might be wrong.
Again.

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.


As long as your engine is not being contaminated by fuel or coolant dilution, 10K should be easily attainable.
 
I think I'm going to go for 10K and do a UOA.

Had I been pulling heavy stuff a lot I might re-think, but I've not towed much and in general, the engine seems relatively healthy.

the first UOA showed some high metals, but that was second OCI after purchase (changed the oil that came with the truck @3k, and sampled the NAPA Synthetic after 6500). the next one (Trop Artic 5w30) looked good with normal metals and no fuel dilution.

I think next time i'll spend the extra 4 bucks and get the Edge Gold Bottle (EP) and just not worry about the 10k, regardless of use. The gold is $28/5qt vs $26/5q so why not go with the gold?

Interestingly enough, NAPA is pretty good about listing the specs on their filters.

here's what they have for the NAPA Gold currently in place
Code:


Part Number: 1372

UPC Number: 765809138407

Style: Spin-On Lube Filter

Service: Lube

Type: Full Flow

Media: Paper

Height: 3.836 (97)*

Outer Diameter Top: 3.668 (93)*

Outer Diameter Bottom: Closed:

Thread Size: 22X1.5 MM

By-Pass Valve Setting: 22 PSI

Anti-Drain Back Valve: Yes

Beta Ratio: 2/20=12/25

Burst Pressure-PSI: 275

Max Flow Rate: 11-13 GPM

Nominal Micron Rating: 21


I cannot find the same information for the Bosch, other than they say that they hold 300% more stuff. the Beta ratio stuff confuses me a bit, but If I did my math right, it looks like
the 50% of 20micron particles were retained and 99.9% of the 25 micron particles were retained.

wish I had the same info for the bosch d+. I think capacity is key with extended OCI's, though, yes?

With that much top off, you can likely run it out to the 142,500 and put that OCD at ease.


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


Sorry, I guess I didn't word my first post the best. What I meant was that 145k / 7500 = 19.33333333, so not an even number. But 142.5k / 7500 = 19. Yes, I'm an accountant so that's my whole number OCD kicking in.

ok, I get where you are at. (engineers and accountants can have the same affinity for numbers, after all)

I'm not starting at zero, though, I'm starting at 130k. plus, i really don't have an interest in how many times I've change the oil over any range of miles; which is why I couldn't follow where you were going.
 
No problem with the Castrol black bottle or either filter choice out to 10,000 miles.

The Bosch Distance + is not the same as a Purolator PureOne.

It's a better, more robust filter.
