10,000 Oil change interval.

[JeffWoodall]

I’m just appreciating your extensive engineering background. You’re equating bad oil to dark oil. Please expand on this. I can’t wait.

My "background" is 20 years Army, Special Ops, 15 years cop, now just a little Security guy that isn't anywhere near as smart as you. I do know people though...bye bye

Not even...just a little bit?...ha!

Thats something I have heard for many many years (that wear metals aid in lubrication) but I don’t know enough about it and can’t find any real information to support my argument so when you’re wrong you’re wrong I guess.

It's all good. We've all got our areas of expertise.

im changing my oil every day
this beast should last forever

Yeah, but are you changing the oil filter everyday also?

Be prepared next time.

I haven't laughed this hard in a long time......?

I'm right there with you on trusting the OLM to 10k. What synthetic oil are you running?

If you're replying to me, I'm running Ford full synthetic.

Strider's oil change reminder came on last week at 4300 miles. I had it done yesterday and the next scheduled change is machine printed for 9300 miles on the windshield sticker. Sounds like a happy medium to me.

Looks good I don’t think anyone would be upset by that report. On my 3.5 expedition I thought about starting to go full synthetic and push to 10k from now on, sitting at 68k currently. I just feel weird about running that long on it knowing I want to keep the truck til it rusts away. Changing that motorcraft oil at 5000 or so just seems like cheap insurance to me.

I have a feeling in a few years we might see 15k or maybe even 20k intervals which seems insane.

My understand is 15K miles for oil changes are the norm in Europe, but I also understand that they only sale full synthetic there.

I'm also impressed with the extended oil change intervals of today's modern engines and oils , but I will still do mine at 5k. Because, turbo. In my locale, the brutal summer Fla heat and towing add additional stresses the vehicle's computer may not be factoring in. Changing the oil at more conservative intervals makes sense for my needs, and I don't view it as an environmentally wasteful as the oil is recycled.

I honestly haven't kept up with the state of motor oil recycling of late, but I know several years ago that most had given up on the practice, it just wasn't cost effective.

 

[Mark Lally]

What brand of oil are you using?

Motorcraft full synthetic.

Mark;

A few points which should increase oil change frequency...
1] once a year even without high miles
2] consistent short trips (under 20miles)and frequent cold starts
3] some folks report fuel contamination of the oil
4] Operating under heavy loads or dirty conditions.
5] extreme heat or cold ambient temperatures


For longer oil change intervals...
1] If you drive consistently long distances (30+ miles) with light loads at steady speeds
2] Vehicle is in excellent mechanical condition and all filters are clean
3] consistently mild ambient temperatures
4] good quality fuel.

Even under ideal conditions I will continue with 1 year/5000mile intervals as a matter of choice.

Perhaps it was a waste of money and environmentally irresponsible to buy a new truck.
To meet those two virtue signalling goals, consider driving less and returning your used oil for recycle and stop wasting your money on oil analysis unless you sample for fleet purposes

Floyd, I premised my post by stating that I'm a current gearhead and a formal Ford tech, as to state I had a better than average understanding as what effects oil degradation, I'm sorry I didn't make that more clear.
As far as buying new being environmentally irresponsible, exactly how long should someone hold onto an old capability lacking vehicle before buying a very capable and energy efficient vehicle to be considered responsible ?
I drove my 89 super coupe for over 20 years ( 18mpg) and then bought a Ford Focus to pass on to my Daughter, then bought a used 2013 Ford fusion hybrid for myself (still have it). Did I waste my money and do damage to the planet with those two purchases too ?

Buying new is no less environmentally irresponsible than 5000mile oil changes.
That was the point, I have two late model Fords and two vintage Fords and I feel as environmentally responsible as you are despite my 5000mile oil change intervals.
As for the "waste of money" part. I stand by my admonition to stop wasting money on oil analysis.
I'm sure your decisions are based on broad and accurate experience and a sense of responsibility, but no more so than mine or many others on this forum who have come to different conclusions.
I am not saying that buying new is environmentally irresponsible , or a waste of money, just that it is at least as much so as the examples you gave. (in comparison.)

BTW; At ExxonMobil we had in house Oil Analysis available and of course all the Mobil 1 we needed.
We used the analysis on vehicles like our CAT 990, but never on light trucks.
Loved the SuperCoupe, nice car but a bit large for my taste, thus my Pinto Sedan with the SVT 2.3L Turbo.
I was not trying to incite umbrage here, only to make a point about responsibility.
I'm sorry I didn't make that more clear.

Truce, but my opinion is still that if oil is still fine after 10k miles, it's wasteful to change it at 5K. I guess it's much less wasteful than the guys on the fuelly app driving rangers that are only getting 14-16 mpg on their new rangers (worse than my large but oh so comfortable, fast and great handling SuperCoupe). I would have love to seen your Pinto.
I think it's in all our best interest to start changing our attitudes on oil change intervals, the science an evidence should drive our decisions. I have to admit though, it was difficult for me to except the new facts also, given that the 3k mile oil change was beat into my head earlier in life.

environmentally responsible to some people means living in caves and wearing loin cloths and eating twigs and berries to survive.

To me being responsible has a different meaning, but the end goal is to reduce waste and take better care of the environment. Take that for what you will, its a simple concept.

I have a neighbor who's into race cars.
his backyard is filled with carcasses of old cars, engines and tires.
not only is it an eyesore, but he doesnt care if he blows an engine and just rolls the bleeding block to the back of the property leaving a trail of oil. if he's burning some brush and somehow a tire rolls into the fire....he looks around so see who's watching and throws on another.
Hes my nemesis when it comes to waste and damaging our environment.

if only he would reduce, re-use and recycle a little more I might not think he's a complete tool.

I think we all know at least one of those dicks.

Yes, I was, and that is what I am running right now too, 5W30 XO-Q1FS; Motorcraft full synthetic
