Coyote Oil Consumption Poll Thread

I burn a quart about every 1k miles. I have never seen anything like this.......

I am still happy with my 11 GT, as it gives so much more in return.

I'd gladly add a quart a week to know Ive got the sickest car on the block.

I bought my car with 5000 miles on it. I have 11,000 now and have never had to add any oil. I did do an oil change at 10,000 but from 5000 to 10,000 miles I checked the oil every week. Never had to add a drop.

I have added 2 quarts in about 3600 miles. The oil consumption of my car appears to be slowing a little. I know from experience with other modern performance vehicles that this is normal, especially with American designed vehicles that typically have ties to Porsche. I don't know if Ford had Porsche assist in the development of the Coyote engine but Ford does have a history of using german designed and built engines. My Harley V-ROD (built by H-D with Porsche helping in the engine development phase) was an oil guzzler when new and when using Harley-Davidson synthetic blend motor oil. But now that it is properly broken in and I also use a full synthetic (Mobil 1), I typically do not add oil between oil changes.

Only recently (after 3k miles) I have started to run the Mustang a little harder; that is, power shifting at red line through 4th gear where the cats make a nasty odor that comes into the car. I don't do this all the time but I know this helps seat the rings better. I will also switch to a full synthetic motor oil (Mobil 1 or Amsoil) when the time comes for a complete oil change. Full synthetics have a higher flash off temperature rating. That is, they can tolerate higher combustion chamber temperatures before they get consumed by the heat of combustion.

The poll really doesn't say much without a timeframe (miles/kilometers driven etc.) for a reference measurement. So far, with 900 miles on mine (in 2.5 weeks) I've had to add <1 quart. She likes oil and I like her happy.

Mine has 3500 miles on it, and has not burnt any. I check it quite often though because of all the mess going around about it. This is my 3rd new Mustang and the 1st one I have ever felt the need to check the oil on. I wonder if the oil issue can help cause #8 to blow. Ford uses oil to cool the pistons and if your 1-2 qts low on oil the remaining oil is going to get hotter meaning the pistons are going to get hotter...

while Im only 1200mi in on my 2011 I can honestly say my car has not burned a dropped. I changed over to full synthetic at 700mi (hadnt burned any) with a little over 500mi on the syn Ive yet to burn any

My dipstick is inaccurate on my 5.0. It read low when I got the car with four miles on it.It looked like it was least 1/2 quart low from the factory. The "o'clock" position of the flat dipstick within the dipstick tube will also"change" the read level .

The MIDDLE of the cross hatched marks is a actual 8 quarts fill on my dipstick. I had thought that the crankcase was about 1/2 quart low from the factory-until I changed the oil myself. And actually measured how much came out. :hihi: And noticed that my new 8 quart fill was at the exact same level on the dipstick cross hatch--right in the middle! :kooky:

If the other dipsticks are the same-some of you are overfilling the crankcase and causing these engines to burn oil because you are effectively overfilling the crankcase! And covering the crank throws with oil :nono:

Too many owners are not actually measuring what is in the crankcase by actually changing the oil themselves and not actually installing 8 quarts and then seeing what the dipstick measures with eight quart fill.

The position of the dipstick tube was changed late in the development of these engines(the tube was originally to be located way below the coil covers) and may cause these engines to read low when the oil level is correct.

IMHO-we are inducing oil burning in some of these poor oil overfilled 5.0s! :gringreen

What does the dipstick read when you think that it is a quart low?

Sorry I'm not buying that theory at all. It takes a long time for all the oil to drain back into the pan after your turn the car off which is why people may think they are a little low if they don't wait for the oil to settle but the factory dipstick isn't inaccurate and there's no way Ford would ship cars with an inaccurate dipstick that would cause people to overfill the engine.

I bought my car with 500 miles on it.

Checked the iol, added about 1/3 of a quart to get it to the top hash mark on my dipstick

Now have a little over 2000 miles, and still at the same mark it was at 500 miles. Just checked it this morning before I headed back from the cape

will keep a eye on it, and let you know

I put a quart in mine at 1k. It now has 3k and hasn't burned a drop since. My oil monitor still says 50% so I'll keep monitoring it to see how it continues.

I'm not picking on you, but if you take the manual at its word you did NOT need to add oil to get the to the top of the crosshatched area. The manual says DO NOT ADD OIL if the level is in between the two holes. According to the manual just over the bottom of the lower hole is "normal operating range".

It is very normal for dipsticks to be inaccurate. The owner's manual for my 92 F150 5.0 states that the dipstick will show overfill immediately after changing the oil and adding the correct amount of 6 quarts! And it just isn't FOMOCO-all Honda's that I have owned have had inaccurate dipstick readings.

I always measure the actual amount of oil drained from the crankcase and noting the level on the dipstick on a new- to- me vehicle before I believe that the level is too low on the dipstick.

After all-a dipstick is a crude 19 Century measuring tool. The depth of the dipstick tube within the engine block will have a large effect on how the dipstick measures.And it is possible that some dipstick tubes are not fully seated within the block hole on some engines. Also-the angle that the dipstick enters the oil level on a flat faced dipstick will have an effect on the readings-change the "o'clock" position of the Coyote dipstick within the tube and see how it effects the reading. Most flat faced dipsticks contact the oil surface at an angle-and it is hard to get accurate readings when the flat face angle can change from one reading to another -because the "o"clock" position changes.

I suspect that the dipstick impressions on these Coyotes wasn't changed after the position of the dipstick tube was changed and moved up higher on the block during development of the engine.

I've changed my oil twice, once at 5k miles and then again at 11k miles. I didn't burn much if any in the first 5k miles, but I burnt a quart in the second 5k miles.

I can live with that, the motor puts out 400+ hp and still gets 23 mpg. I can compromise.

FYI, I didn't reset my oil life meter after my first change. It went to 11k miles before I got the warning to change my oil, even though I had done it twice by then. :heha:

Sorry not buying it. The Coyote of all engines has a perfect setup as the passage is within the engine and not an external dipstick tube that fits via outside the block. The depth of the dipstick can never change on the Coyote engine as it seats into the valve cover. I mean really are you trying to say that all the money and technology put into engines by manufacturers and they treat the oil measurement as an afterthought? There's no way manufacturers are going to leave service techs and owners with a simple guess of oil level. Sorry but the readings are accurate and repeatable on most cars. All you have to do is ensure that you've fully inserted the dipstick and the only thing that can vary the measurement is if you are on level ground or not.

I have just over 3300 miles and have added only 1 Quart at about 2000 mile mark so no big deal.My CTS i had befor the Mustang would use 1 Quart every 2000 miles i just checked every month car had 42000 miles on her when i traded up.nothing to worry about,no smoke coming out of the pipes i wont worry about it.

My dipstick is inaccurate on my 5.0. It read low when I got the car [snip]

Then your dipstick is accurate. SOP dictates a correct crankcase fill in the middle of the cross hatch.


As for overfilling. If you overfill enough to damage, your crankshaft will whip it up into a foam which you'll see on the dip stick.

2400 miles and oil is at top hatch marks just below top hole. First 1/4 mile run was at about 250 miles on odometer.

I need a 5.0 aluminator and some boost!

19000 km and 3 oil changes later - never had to add anything. I check every second fuel fill.

4200 miles and no oil consumption at all.
