Ford V-10 oil burn September 23, 2023, 05:57:03 am My 2006 Ford E450 V10 has burned a quart of oil every thousand miles for 70,000 miles. Now at 80,000 miles the oil burn rate has dropped to near zero. Just an observation. I don’t know if that is good or bad.I have always used Mobil1 synthetic 10W-30.
Re: Ford V-10 oil burn Reply #1 – September 23, 2023, 10:31:26 am The correct oil spec is 5W-20 oil. I don't know why using heavier oil might increase consumption, but suddenly reduced consumption would suggest an alternate path of oil that is now plugged. Excessive oil consumption in more recent models was linked to failing valve seals.Steve 1 Likes
Re: Ford V-10 oil burn Reply #2 – September 23, 2023, 11:48:41 am V10s are known to burn some oil and this is considered normal if it uses a quart per thousand miles or less.The only thing I can think of that decreases oil consumption is a plugged PCV (positive crankcase ventilation) valve that had previously been sucking an abnormal amount of oil into the base of the throttle body. The PCV is a maintenance item requiring period changing according to the Ford manual and is located on the passenger side valve cover. The standard test is to remove the valve and shake it. If it rattles, it is still good. No rattle means replace it.There is a u-shape hose that attaches to the base of the throttle that connects to the hose running up to the PCV, the u-shape hose is known to deteriorate over time and many miles. It can pop off or develop leaks. It is recommended to change this hose at the same time the PCV valve is replaced. FYI, it is a PIA to change.Larry

Re: Ford V-10 oil burn Reply #4 – September 23, 2023, 01:31:35 pm Hi Harry; My 1999 engine spec is 5W-30 oil, and I use Mobil 1 exclusively. It has always used about 1/2 quart every 1000 miles, which hasn't changed in 58k miles. Your 2006 is a lot different 'beastie' than my 'prehistoric' engine. Many changes were made for the 2000 engine. From what I've heard, Ford changed most of the engine except the number of pistons. Here is a Youtube for the V10 on an Excursion. Probably much harder on the E450. https://www.google.com/search?q=youtube+for+changing+pcv+valve+2006+ford+v10&rlz=1C1VDKB_enUS947US947&oq=youtube+for+changing+pcv+valve+2006+ford+v10&aqs=chrome..69i57j69i64l2.139031j0j7&sourceid=chrome&ie=UTF-8#fpstate=ive&vld=cid:a9186f72,vid:24ffIOR_ImM,st:0 A good example of the cracked hose right at the valve and a demo of a hose pulling tool.

Re: Ford V-10 oil burn Reply #5 – September 23, 2023, 01:47:37 pm For what it's worth, my 2003 doesn't have the "heater coil" portion shown in the video above of the 2000 model. That video also doesn't show the U-shaped hose, which is that part that is tough to reach. Rich (who recently changed both as preventative maintenance at 110k miles) 1 Likes
