Dealer said 5000 mile service interval is better ?

[billbillw]

Dealers telling you that oil changes should be more frequent than the manufacturer calls for is like real estate agents telling you it's the right time to buy or sell. Of course they'll tell you that. They stand to make twice the money off of you.

And you think the manufacturer wants the vehicle to last 400k miles? No they want to sell you a new one every 10 years or less.

Maybe, but automakers are also smart enough to know that anyone that suffers a catastrophic engine failure in a car that's less than 10 years old isn't going to buy another of the same brand.

Well, the 2.7 Ecoboost is tuned higher than either of them. Again, not telling anyone what to do. But stories of a ( shorter than recommended) mile oil change interval will extend engine life just isn't necessarily true. If there was that much difference in how much wear there was between 10000 mile oil and 5000 mile oil, that would be different. But the difference in wear, based on oil sample FACTS, shows it just doesn't make a difference in actual engine wear. The biggest reason oil needs changed is the additive package. That is what controls acid formation, foaming, and cleaning. Otherwise the actual LUBRICATION is doing just fine. That is what your filter is for, to remove abrasive particles, and it does that rather well.

Agreed on all that, but in bold, this is why you change the oil before the 10k miles hits. The filter media is tiny. Hardly any surface area, and it will fill with debris, and it can clog.

FordPass also will make oil life 0% at 1 year btw. Generally in low mileage vehicles you would replace the oil every 6 months, but I guess 1 year is ok-ish.

I have cut my share of filters open. Have you noticed the newer vehicles seem to have smaller filters? That is because they are still way more than adequate to filter the oil for the recommended change interval... and beyond. I just have not run into any filter that showed signs of having enough contamination to cause it to go into bypass. Engines today simply do not produce the debris that might have clogged filters in decades past. Oil is run at a higher temperature ( keeps acid formation way down, as well as sludge buildup) and the much higher precision of todays machining operations and tooling mean there is little wear due to misfitting parts. Closed emission systems and high efficiency air filtration mean there is no outside dirt getting into the engine compared, again, to engines from the era where few intervals were past 6000 miles.
Yes, "they" want you to change the oil every year, even if it has almost no miles. Do that under warranty of course, but after that I don't worry about it. My GT 350 has the oil light on now...and has about 3000 miles on that oil. I will get to it soon, but I know it is a waste to change it. I will do it anyway, so that should please some here to show I can be a hypocrite!

The turbo itself doesn't wear the oil, but the bearing demands good oil. What wears the oil out is the blowby from boost and fuel dilution from the DI.

Better explanation than mine, thanks. To catch the blow blow by and fuel dilution, I had installed Buscher’s oil catch can because a lot of my driving are short trips and I intend to keep my Mav a long time.

Now that said, if you THINK you have a fuel dilution problem as some claim the 2.0 EcoBoost has, then do yourself a $50 favor and have your oil tested. At 3000 miles or whatever you change at. Then you will know if there is ANY fuel in the oil. Or Coolant. Or about 15 other things....
Decades ago changing oil at 3000 miles was justified. But oil and engine technology today make that questionable. That would be more than 3 oil changes for every one at the 10,000 service. Every time you remove the oil drain plug, pull the oil filter, you run a risk of something going wrong. A loose drain plug will kill that engine faster than old oil!

Thanks

This is an important point that it appears most are ignoring.

I love oil centric forum posts. No matter what vehicle/engine is being discussed they always end up the same way. Dealer/family member/Rando on YouTube/dog said do it this way, run only this brand. Then the 23&Me oil analysis and personal experience guys pop in. Always a good time.

Consumers demand (and government pushes) longer oil change intervals (better for environment, less costly, less hassle...) and manufacturers respond. Ford warranties engine for 60K miles and they must have data that engine warranty claims will not go up with the 10K or annual frequency oil change. Does that mean this is the best frequency to change if manufacturers had to warranty to 150K to 200K miles? I don't think so but as one poster pointed out, it is really about the oil analysis. I do not buy the argument that Ford says it is okay to change at annual or 10K frequency, they do not own the vehicle and only own the engine reliability via their warranty to 60K miles. So, without data at hand, and realizing the manufacturer may not really be concerned as long as the engine gets past the warranty period, and that I would be looking to maximize engine life, I will be changing at every 5K miles until I see some oil analysis data that proves otherwise. Someone may ask why not every 3K miles or every 1K mile, all I can say is I have been changing oil in my vehicles for 30 years and 5K is what "feels right" to me.

I'm not sure if much has changed, aside from manufacturers allowing more mileage now between oil changes, but Consumer Reports did a long study on oil change recommendations. This was when all the quick oil change places were recommending only 3000 miles between oil changes. CR did a study on taxis (I believe in New York), since they run pretty much 24 hours a day. In a certain number of taxis they changed the oil every 3000 miles and another set of taxis at mileage recommended by the manufacturer. After a couple years, they had mechanics inspect engines in both sets of taxis and determined that the ones changed at manufacturer recommendations had no more wear then the ones changed every 3000 miles.

In 10 years you won't be able to buy a gas truck from Ford so oil changes will be irrelevant. This will likely be the last Ford I ever own.

In giving thought to the oil change of when, we need to remind ourselves not to compare port injection with direct injection engines that recycle what has not been burned up in the combustion stage back into the intake; used to blow out of the crankcase and because it longer does so, it gets dumped back into the engine compromising the oil and ultimately the intake valves.

You sure about this? EV is not ready for prime time and we all know what happens when one hurry’s to get stuff done. Turns into a big cluster fu*k
Sure, EV sounds great but who’s going to cough the infrastructure out of their azz to charge ‘‘em all?
Ever been in Chicago hoods? Sometimes you’re lucky to park within 2-3 blocks of your house. If they do string up wires the gangs will steal it for scrap. The older Chicago houses have 50amp service so even if they have a garage. No dice on charging.
Not very well planned out now is it?
