Looking for the average oil consumption on the 5.0L V8 engine.

Dealer service indicated the 5.0L uses oil.

If so, why does this engine consume so much oil.

 

My 2014 5.0 uses no appreciable amount between 5000 mile oil changes

 

My 2013 5.0 uses little oil between 5K.
I check oil, fluids, tire press at least once a month.

That being said, Ford's placement of the dip stick certainly does not encourage frequent oil checking. I am average height and have to use a collapsible step stool to reach the dip stick and a flashlight to see the hole to put the dipstick back in place.

 

My 5.0 uses no oil. I check it in the morning (so the engine has been off for many hours) once per month. It is at the exact same spot on the dipstick each time (second X from the top of the full zone). I get about 7500-8500 between oil changes (I tow a 3500 lb boat and a 3300 lb camping pop-up trailer on the interstate but take short trips to work). I use the oil life monitor to tell me when to change the oil, but change it at about 10%. I use Royal Purple full synthetic and motorcraft filters. I have seen other posts/threads here about 5.0 oil consumption; however thus far mine uses none. I have ~26,300 miles on my truck now. I also just returned from a 700 mile trip with the camper doing 75 miles per hour. Incidentally, I got 15 mpg at that speed (real calculation not the trip computer).

 

ok have had a long talk with service guy and local serves teck about this. service righter could not say much, but the teck said he noticed that trucks / 5.0 that where broke in with a heavy foot seem to not burn oil. where as pampered motors seem to burn oil? so I asked how dose he know who drives hard and who's the little old lady? he said the computer tells the tell if you pamper it or beat it. he went on to tell me its better to brake in a motor hard just for that reason. if you ever go to the drag races you will notice after the race team builds a motor they run it at hi RPM's till rings set granted the motor they use it three time maybe four and it gets a complete tare down. but after every run the thing gets striped of its intake and heads to see if its ok in side.
but you got to think if 90% NHRA dose it there a reason.

 

I haven't noticed my truck using oil in the 3 1/2 years I've had it.

 

I have a 2018 with 8300 miles I checked the oil before the first oil change 4000 and it was at the bottom of the stick, had the dealer change the oil because it was free I just checked at 8300 and I added 2 quarts No engine should burn 2 quarts that quick. after long thought on this I believe the problem is the direct injection which puts fuel directly into the cylinder thus washing the walls clean of oil which is not good for break in. The idea of the engine needing to be stomped on for break in is ridiculous a good break in would be in high gear with heavy load on and off for a period of time. I will be taking the truck in for another free oil change and letting them Know I want to start monitoring the level thru them but I am quite sure that I will be getting a new engine. I will keep everyone informed on this issue

 

My 2010 used no oil at 5000-7000 oil changes, up until 45,xxx miles when a lady blew through a stop sign and destroyed. it. My 2013 at 61,xxx miles and the same 5000-7000 mile oil changes uses no oil whatsoever.

As far as break in, there always seems to be polarized camps: baby it "like the manual says" or "drive it like you stole it". I think I just drive it like I drive it from day 1, doing nothing special with it. This has always seemed to work well for my cars, trucks and motorcycles.

 

I have a 2011 f150 with the 5.0. Which was the first year to use the 5.0. My truck now has 123,000 miles on the clock. I bought it used with 35k on the clock. Now with that said I noticed that my truck has always used about 1-2 quarts of oil between oil changes. I noticed with mine that the harder I run the truck the more it consumes. And the easier I run the truck the less is consumed. There are I believe to be a few reasons for this. But direct injection is not one of them. I say that because until MY2018 the 5.0 didn't have direct injection. Only the 3.5 egoboost had direct injection. Now what I believe are some of the reasons are 1 these engines have piston cooling jets built into the engine. What that does is it spray the engine's oil onto the pistons during each revolution to help cool the piston thus minimizing the friction in the cylinder and ultimately reducing wear. The trade off hear is that the engine will burn more oil. Which in this case isn't necessarily cause for alarm as long as the oil level is monitored. And coincides with I have noticed with my truck.2 Another reason that I have heard has to do with the rings themselves not being stiff enough to not let the oil slip by. And this issue and reasoning isn't limited to just Ford or the 5.0, but affect all manufacturers and all modern engines. I personally don't by that, but it's what I heard among the automotive industry. 3 Has to do with the thinner viscosity of the oils required in these modern engines. They are slipperier than ever and are thinner in order to protect the engine by being able to get into the much tighter tolerances that are built into OHC and DOHC engines. And this is why a lot of people are now installing oil catch cans onto these and other OHC engines. But as long as your monitor your oil level and add as needed you shouldn't have any issues.

 

Piston cooling jets were deleted in 2012. If you look in the intake of 5.0 engines that burn oil the common them is the mess. It's not getting past the rings but rather pulling through the PCV and it makes a nasty mess in the intake. There is also variations in the orifice size of the PCV. It's worth swapping the PCV and adding a oil catch can.

 

That is something I did not know before about the piston cooling jets. Thanks for that. I did hear that Ford Performance has released there own oil catch can for these trucks. After years of Ford saying that they weren't necessary on these engines.

 

The 5.0 on the track in a mustang is terrible with oil control. You can fill up a catch can in a couple laps. They should have done a better baffle inside the cover.

 

after some more research I have found that ford has a clearance problem do to the different grades of aluminum thus different rates of expansion lets say there are are 1,2 and 3 grades 1 being worst 3 being good,if you have a grade 1 block and a grade 3 piston, the block expands faster thus fords solution tighten the clearance's between piston and cylinder problem with that is reverse that and piston expands more than the block scores cylinder. ford obviously can not control this in mass production maybe that is why they went to graphite iron on the 2.7 eco. Some hypo engine builders have found that the 2018 blocks will move 5 thousands at 200 degrees.
