Except, the Owners Manual states that the 2.3L (Ranger equivalent ) takes 6.2 qts.Thats a good point, and Ford addressed your concern in the engine desugn, according to this May 12 article on Bronco Nation, to prevent oil starvation on the trail:
No you aren't. Maintain it at the max mark. The engine will operate just fine in the safe operating range. If the safe operating range is a half inch lower than it should be then if you're maintaining the level at the top of the range you should be in the actual safe operating range. It's simple, it's defensible. It won't raise questions if there's an issue.
Partially true, but mostly false. It costs a small fortune to release NEW parts into the Worldwide Engineering Release System, let alone the costs associated wwith sourcing and re-tooling for said parts. If a part or assembly CAN ber carried over/re-used, it would be, trust me.
Thank you for extend the explanation from engineer department point of view.
C5 doing turns nothing else on the road can do would hit an electronic cut out without a bit extra. O to have a small block Chevy Bronco.
i had a heads/cam/ 6speed C5 for 5 years. Made 411rwhp. I used to sling it around a road course and even some back roads
The entire point of the thread is that all of us with factory-filled 2.7s have dipsticks that are measuring about 1/2 above the max mark. If we overfill it, to that same point on the dipstick by adding 7 quarts after a drain, we'd simply be doing the exact same thing the factory did. As is, the folks in this forum who have had a first oil change at a Ford dealership are coming back and reporting oil levels way over the max line...which is why we hope Ford gives all of us an official statement that tells us to either follow the part in the manual that says 7 quart capacity with oil and filter change OR the part of the manual that says don't overfill beyond the max mark...but as of now, those sections of the manual contradict one another.
Regardless of the intent of the 7 quart capacity, the reality is that adding 7 quarts after draining 7 quarts puts the oil level way over the full mark. If Ford's answer to having enough oil in the engine to address extreme angles is simply to overfill our engines, that is not confidence-inspiring. I don't think it is too much to ask of Ford to simply clarify why the dipstick does not reflect an accurate oil level (or, if it does, why the "proper" oil level is so far over the max mark on the dipstick). Oil pans designed for extreme angles typically have baffles and/or a windage tray...or the motors will run a dry sump.Here is the May 12 post on Bronco Nation that explains why the oil capacity is greater for the Bronco version of the 2.7 Eco:
If it were that simple then how do people who simply throw in 7 quarts monitor oil levels between oil changes? They would have to scribe a new reference point on the dipstick...and for folks who do not do their own maintenance, whoever does their oil changes will more than likely add the wrong amount of oil or won't add enough oil if the level doesn't match the proper marks. Much easier for Ford to provide an accurate dipstick.
Germans are way ahead when it comes to oil level warning systems...if our Broncos had a low (and high) sensor, like a BMW or Mercedez has, I wouldn't stress about a dipstick as much...however, both my Sprinter and my former G series had not only sensors (for those who prefer dash warnings) but also very accurate dipsticks (for those of us who don't trust the fairly inaccurate "ballpark figure" sensors). Point again being that Ford in this particular case is irresponsible for not being able to build a product that has an inaccurate dipstick (or oil capacity indication). How hard can it be to make a car that has a manual/vehicle in which the oil level rec. matches the provided instructions/dipstick? Also...as you pointed out your BMW did not have a dipstick. If our Broncos didn't have a dipstick, this entire topic would be pointless. Because our Broncos do have a dipstick, however, and because they are apparently inaccurate, Ford needs to give us some direction IMHO.
