First oil change

[Ted Striker]

I wonder if there were people in the 50's that said:

"I don't care if the manual says that I should change the oil in my 1955 Ford F-100 every 3,000 miles, I'm going to change it every 1,000 miles."

So some guy's opinion seems to be an irritant that has found its way into your colon. Chill out. It is a free country and nobody needs scientific evidence to justify a decision, even if it honks someone else off. But since you asked, I've got some data below that justifies it, at least in my mind, or in the @JET_83 's mind.

Yes, you can go 7500 on your first oil change. We got that, which should make you feel good. (See, feelings are ok!) But I promise you that only 4k on the original oil will have more contaminates, silicon, and wear particles and will take the oil closer to its limits than 7500 on any subsequent oil fill. Plus, he gets to decide which oil and filter to use, so he knows what is in there.

The data from my engine suggests it is not a bad idea to do it sooner. I changed mine at 2k miles and yes, the oil was serviceable and could have gone 7500, but why? Here is the UOA which shows LOTS of shit in there and much of it was present as early as 500 miles.

On my 3.6, wear metals and silicon are FAR greater at 2k than the 4/18/20 sample that ran 8k miles. That right there justifies his reasoning for changing early.

The good news at 2k was that the oil itself was still fine, with a high flash point, no sign of fuel or water and viscosity where it should be. So yep, it could have gone longer. But I didn't feel good with it holding all that crap in suspension and wanted to get it out of there. No harm in that. My 2008 JK 3.8 got its first change at only 500 miles, then at another 1k, then at another 3k, then every 6k since then. Why? It made me feel good. Just like spending money on cigarettes makes another guy feel good. That 3.8 is running like new at 168k miles and counting. So there clearly is no harm at all in getting a little peace of mind while at the same time enjoying maintaining your rig.

And what does that have to do with the price of fish in Denmark?

I see now where you are coming from.

You are on your own in the basement now with your Mountain Dew and Cheetos.

I use the same bud, change mine every 4,000 is what I’ve always done regardless, but for people that decide to go 10,000 per oil change there’s a very good chance there’s will start using way more oil than designed, oil isn’t that expensive to save a motor.

Let the misinformation train start chugging away!

You don't need to change it every 4k. But if you want to, you can. And there's nothing wrong with people who are able to go 10k between changes. To try and definitively say otherwise and "point it out" to us is just false. And to try and instill fear by saying there's "a very good chance" of something when in fact there isn't does not help anyone at all.

You can do what you want. Where you're going too far, though, is telling everyone else that you know best when you don't. As @ShadowsPapa said, what is this based on? Because if all these oil threads have shown us anything it's that you never know how good oil is just by looking at it.

If you have an actual oil analysis that shows an issue, that would be great to see. Because then, we could start trying to figure out why you have a problem. But without that, you're spinning tales of woe that have no factual basis.

guy above did, different synthetics break down faster, go ahead and go 10,000 and burn oil, that’s your choice.

His analysis showed it could still go further than his change interval. And that was even on the first oil change. Subsequent oil changes get longer life than the first. What are you even talking about?

He's a troll. I picked up on it late. But The Cheetos and Mountain Dew and the stench of his Mom's basement are all clearly clues.

I tend to agree now.

Perhaps I should've just stuck to my "don't comment in oil threads" rule. Too many people like this that don't know what the facts are, trying to tell others how to do oil changes. You never win. Why do I do this to myself.

not all synthetics have the same oil life, genius.

Aren't some oils just naturally darker than others?
And isn't it supposed to be thin? I mean it is 0W-20 after all.
Thick, globby, or chunky oil = problem.

This seems about as effective as a butt dyno on engine mods.

EDIT: SON OF A B!TC# I commented on another oil thread. Damnit damnit damnit damnit damnit.

Yes - some is darker than others, a lot of "it depends" in there - the base stock and their proprietary additives= color.
The oil used here will seem quite thin compared to what older people are used to finding in vehicles of 20 years ago.

but for people that decide to go 10,000 per oil change there’s a very good chance there’s will start using way more oil than designed

Not sure where that comes from. I did 3500 miles even on OLD SCHOOL engines with fewer controls! These engines run at or close to stoich much of the time.
That means less unburned fuel getting down there.
As far as miles - it all depends on how you drive the thing. Some people are going to see these go 200,000 miles with oil changes done 8,000-9,000 miles or a bit more.
Do what you want, it's your vehicle, your oil money, etc.
But there's a reason they can specify 10,000 miles on these engines. Technology.
If you tow, if you do a lot of shorter drives, if the oil never gets up to temperature in colder weather - don't go 10. If you tow in the summer and the oil gets up to 240 or better, don't go 10 but other people - even me - could go 8-10,000 miles and never see an issue.

If I can go 3,500 miles or so between oil changes on a 1980s carbureted engine and go over 160,000 miles and not burn oil (didn't have to add between changes) I can certainly go double that or more on this engine.

But you do what you want to do with your truck.
I'll base my choices on experience as a mechanic and engine builder (and some science)

enjoy burning oil ?

And you are basing that on?? Automotive degree?

Same here. I tend to fall for that shit when I'm on vacation. Lol.

Here's a good article (from 2008, oil has only gotten better since then) that explains exactly why your assertions are a myth:

https://www.scientificamerican.com/article/oil-change-truths/

Those who rarely drive more than 10 miles at a time (which doesn’t get the oil hot enough to boil off moisture condensation) or who start their car frequently when the oil isn’t hot (when most engine wear occurs) should change their oil more often—at least twice a year...

@ShadowsPapa is right again.

...commuters who drive more than 20 miles a day on mostly flat freeway can go as far as their owner’s manual recommends, if not longer, between changes.

That's more than 4,000 miles. Twice as much if not more depending on conditions.

Davis says that educated drivers should opt for longer lasting, better performing synthetic oils, which are “most likely good for 10,000 to 15,000 miles or six months” whether or not their manufacturers recommend more frequent changes or not. Some synthetic motor oils, like Amsoil, NEO and Red Line, to name a few, are created specifically to last 25,000 miles or one year before needing a change.

Educated drivers. I suppose non-educated drivers should change every 4k?


There are also plenty of other great articles out there saying exactly the same thing. More frequent changes are a quick-lube moneygrab. Nothing more. Enjoy your reading.

lol, I guess some people don’t care if their engine starts to use more oil than designed and having to add to all because of neglect.

What does oil change frequency have to do with burning oil? No one is saying don't check your oil, so you'll still know if it's being consumed. Just that there's no reason to change every 4,000 miles. The oil will always look thin, because it's 0w-20. It's not neglect if you're following the manual and the oil life indicator. If the engine fails and you're doing those things, you get a new one for free, and it probably would have failed either way. And no, they don't write the service intervals to make you buy new cars faster. Because if they did that, people would switch makes from frustration over failing engines. There would be no loyalty.
