7500 on an oil change....who does that?

Just got an 08 V-10 F-350 dually. manual says 7500 between oil changes. I rememeber when auto OEMs used to say 3000 miles or 90days/6months, etc.

does anyone really let thir oil run 7500 miles...what if you only drive 3000 miles a year...2 years between changes???

since i bought my truck brand new ive always ran Pennzoil full synthetic 5w20 and a Ford oil filter and i only go 3500 to 3700 miles between oil changes. I know they say you can go further but for under $30 dollars to do my oil change i change it regardless. I will say alot of the diesel guys on here go that far BUT they are doing oil analysis so they know exactly how their oil is breaking down etc.....

If that was the case, you'd want to change it yearly.
Everyone has a preference on OC. It's fine to go 7,500 if you use a full synthetic IMO, otherwise I'd do 5k mile OC.

I gotta say, the oil in my Ecoboost looks like it's been in there for 20k miles when I change it, and I change it every 4k miles with Mobil 1

I've always believed in 3,000 mile oil changes in my truck mainly because I tow a lot and idle. My Girlfriend has a 2010 Prius and has a 10k mile oil change interval backed by Toyota.

My plow truck gets an oil change once a year. With modern oils and quality filters I can't see an issue with a 7500 mile oil change when using synthetics.

I have always done 5,000 mile changes. That way I don't have to keep track of when it was last changed, when it's due again, etc. On my road tractor I get the oil changed about every 40k miles and never have any issues. I don't see anything wrong with the 7,500 mile interval, I just prefer 5,000.

Long Drain oil intervals

my 1967 Mustang 390 engine had manufacture recommendation of 6000 miles

I don't change my oil in my truck unless the analysis lab says to change it.
I usually go around 80,000 miles on one oil change when the lab report starts
to show lower values like high oxidation/nitration levels and TBN readings below 2

The 3000 mile oil change is simply a ploy to rip of the uneducated and as you can see it works marvelously!

I will on a '13 SD and a '14 Fusion 2.0EB . And that turns out to be about 3 oil changes a year.

I did a couple UOA's @ 5K intervals at 75K and 90K total miles on my '03 5.4 and Blackstone indicated that I could go up to 7.5K based on their results.

Oils are better than they used to be.

As long as Ford is ok with it, I can live with it.

FORD can kiss it, When you have a vehicle that is new, I buy two years worth of oil and filters from the place I buy the car.
I then sell that junk and buy the right lubricant and filters and ride!

When an issue comes up I simply drive/tow it in and hand them the oil receipt, never a problem.

i don't care what Ford says, what oil manufactures say this is my 30k truck ill spend a measly 30 dollars ever 3500 miles and ill keep doing so. Just like sammy77 stated oil looked like dirt after only 4k, now you could say o the motor is brand new and broke in so the oil is dirty..... not me. To the OP do how you see fit it is your TRUCK and your MONEY

So let me grasp this theory of yours.
Like you stated above you drain drain drain, cheap insurance.

So in reality you use regular discount filters, the best they do in capturing contaminate is 30/40 micron nominal which is OEM quality, So what your really doing is running 100% of the time 1 through 30 microns worth of dirt through your engine everyday, these particles are never caught so they cause most of the engine wear in all engines.
I should know, I work at machine shops and supply them with parts.
I have a large collection of engines and I can swing a wrench or two.

So I am just using the SAE figures and results of engine wear testing not my own.

I would rather use an Oil Analysis Lab than wives tale opinions to lubricate my engines. Of course all my engines are built by me and not the manufacture.

I have about 26,000 on my oil right now and probably wont need a change for another 3/4 years

What's with all the hostility?

If you want to change your oil every 3K, every weekend, or every half century, knock yourself out. I DGAF.

I was answering the OP. With my 2 brand new Ford vehicles, I'm going to change the oil when the oil minder reminds me. ~7.5K interval.

My truck runs on CNG so when I take my truck in every 5K to change the oil they always freak out because the oil is so clean(almost looks brand new) I got a kit from blackstone labs to evaluate my oil but I have yet to send it into them.

So my statements were directed to him.... then he goes again at me saying i use cheap inferior oil and filters and this huge theory about how my products only filter 2 microns when if he read what i posted three post before i again use Motorcraft filters and pennzoil synthetic oil
