GEN 2 First oil change

[CFIT]

Wow. Everybody doing something different. Wonder who is right?

I'm going to try something different and do what the manual says.

Unless I missed something, it seems like the manual is saying to sit tight until the truck tells you to change the oil. Is that your plan? I'm not being critical by the way, just curious.

Yes. That's my plan. If I wanted to change oil every 5k miles then I would just use non synthetic

this is quite possibly, the dumbest thing you could do.


Go'head and do what the factory says and see how the engine lasts up and around 80-100+K miles. See how much sludge builds up inside the engine.

Or, the most simplistic way and cheapest thing you can do, is change the oil regularly, and 7500 miles is a perfect conservative side of a full synthetic oil base, that errors on caution.

If you want to stretch it out, do a blackstone and see how far you safely can go. On conventional dyno diesel oil, on my superduty I was able to get 9500 miles per oil service safely with blackstone analysis even though Ford says 7500 miles.

But, this was after starting at 5K and slowly working my way up to that number over the span of 40K miles.

Your mileage may vary, but I think you are doing a very fool hearty decision for such a simple/cheap thing to do.

pretty sure the op just wanted to know what we were personally doing. it was never a question of right or wrong. even though some of us may share similar thinking about is best for our truck, the only wrong answer is exceeding the factory recommendation too much. also simi synthetic blend is minimum for our trucks. full synthetic is just like putting in 91 oct, just makes us feel like we are taking great care of our trucks and wanting the maximum performance and reliability. not gonna knock the guy that follows factory recommendation, but will laugh at the ones that try 15-20k intervals on regular full synthetic or less.

I'm curious why people don't trust the engineers and scientists that designed and tested our engines? If anything Ford is heavily incentivized to make us change our oil more frequently than necessary.

1) They don't pay for the oil change
2) Additional revenue makes their dealers happy
3) If our engines fail during the warranty period, Ford replaces it
4) Out of warranty engines blowing up at 100k mi damages Ford's reputation for building reliable vehicles and that perception directly affects new vehicle sales

Parts and labor on an engine swap is probably close to $10k, so I'm sure Ford is extremely confident their oil change interval is perfectly adequate. If 5k miles was better for our engines, then that is what they would recommend. The extra safety margin doesn't cost Ford a dime and if it better protects their warranty engines and the brand's reputation, why wouldn't they do it? Instead they tell us 10k miles is plenty adequate to maintain our warranties and I'm inclined to believe them.

And not only that, it is standard practice in engineering to add a safety factor, often 50% or 100% to account for manufacturing variations and less than ideal users. That safety margin means Ford engineers actually believe the recommended blended motor oil will last 15k to 20k miles under normal conditions. Since Ford is heavily incentivized to recommend more frequent oil changes than necessary, most likely 10k miles is more frequent than what is necessary to maintain a healthy engine.

Many people fall back on the "cheap insurance" argument, but that same rationale applies to wearing a helmet while driving. How many people wear helmets in traffic "just to be safe"?

Namely because I own a BMW/RR shop, and I know first hand experience of using full synthetic intimately beyond 10K miles, 15K and 20K miles on thousands of BMW's..... turbo 6 cylinders mainly.
If full synthetic can't keep up past 12-15K miles and sludge the engine, what do you think semi synthetic will do under that same scenario....

I know this. Oil services from most manufacturers are there to protect themselves until it gets out of warranty. That's it.


And tell me that an engineer is never wrong. Please. I need a laugh. I fix engineer's mistakes on a daily basis.

Realistically, a HUGE part of recommended service intervals surrounds what the end user is likely to be willing to do. For instance, let's say, just for the sake of argument, that the absolute best practice, re: oil changes is to change the oil every 100 miles for the first 1000, then every 250 miles for the next 1000, then every 1000 miles for the next 3000, then every 5000 miles. The long and short of it is that pretty much NO ONE is going to do that... so the engineers make a "good enough" recommendation that is likely to be palatable to the average customer.

Really and truly, changing oil based on mileage alone is like choosing a truck based on paint color alone... it's certainly a potential factor, but it is by no means all-inclusive in regard to what is actually best for the application. Average oil temperature, average trip duration (especially relative to ambient temperature and humidity), fuel quality, engine RPM/loading, etc... all have the potential to be just as (or even more) important as mileage in regard to the condition of the oil at whatever change interval floats your boat. Some, all, or perhaps even additional parameters of this sort may be factored into the oil life calculation as displayed on the dash... or may not. I don't know, so I'd rather err on the side of caution and shell out a few extra bucks for an oil change that I may not need than to wait for the truck to tell me when it's time and just cross my fingers that it's right.

But what brand of oil is best?

Kidding of course. Interesting to see that it doesn't matter what you drive or ride- if its a 4 stroke people will argue about frequency of oil changes and brand. Always.

Burnout is 1000% right. We changed oil in our KTM after every RACE. Same with the F1000 race car because they were run at redline and max temps. Drive the Raptor like a mini van and you'd probably be fine with a high quality synthetic and 20k miles. Take it to the sand dunes and I'd step that up a bit. YMMV.

Well, I think your response is one of the dumbest I have heard. Almost as stupid as those who do their first change at 500 miles and then every 2000 miles with full synthetic. You idiots make these decisions on pure fairytales.

I have a 100,000 mile warranty and never keep any vehicle that long anyway. Come to think of it, I may not change my oil EVER!

All major manufactures are moving to 10k oil changes. Maybe these companies need to come talk to you since you obviously know a lot more than all their engineers do.
