I have a 2015 F250 6.2L, and it uses about a litre of oil every 2000 Km (a quart every 1200-1500 miles). Had the dealer do the suggested valve cover change (https://ford.oemdtc.com/1301/excessive-oil-consumption-2015-2016-ford-f-super-duty-f-250-f-350)- this did not change the oil consumption. Any suggestions on the best oil to use to see if different oil will reduce this consumption? Thanks!

 

My 2016 doesnt use enough in between the 5,000 mile change interval to say so...maybe a 1/4 of a quart. Plus i tow a trailer evryday during the week.
They did change the oil weight rating though...im not sure what your cap says. But the correct weight now is 5w30. Everything ive read is to do NOT use a heavier weight oil.

 

 

my 2012 6.2L has 156,000 miles... city driving is 1/4 quart in 2,000 miles.. but on the road... zero over 2,000 miles towing 9,000 pound trailer over 4 days.

also many today oils evaporate... try changing brands.... Pennzoil is known for this.

I use 10w30 synthetic oil... for the number of miles on engine.. ( my opinion )

 

 

Thanks for the replies - my truck only has 40,000 km (24,000 miles), and it doesn't seem to matter if I'm towing our 7000 lb trailer or not. I'll try the 5-30 synthetic oil and see if that makes a difference. Any suggestions on the best brand of oil? Thanks again guys!

 

any well known brand honestly. They're all good

 

Great thanks!

Does it stop drinking half way down the stick?

I think my work truck only takes about 6 qts. Put in 7, and it drinks it. Work make me go to Valvoline quicky lube. Rat *******s fill the oil up all the way and show it to me like it's a good thing. LOL. At least my cat will be well lubed.

 

Just wanted to post on here for anyone looking into the oil consumption problem on the 6.2 gas motor, I researched this problem a lot and finally went to get the “updated” valve cover ford put out with its TSB on the oil consumption problem with the effected years 6.2l. Long story short the “updated” valve cover is exactly the same as the one that is in the truck already, absolutely no difference. I got my valve cover off and compared the two to actually find that even though they changed the part # on the box (which they’ve done 4 or 5 times with the same valve cover, I found this out by talking with a close friend of mine who works the parts counter at ford) the part number stamped on the inside of both valve covers were exactly the same, after cleaning mine I could see there was actually nothing wrong or broken about it. Essentially what is happening is the oil is getting sucked up through the pcv because it’s not draining from the baffle like it should before reaching the pcv at the end of the baffle. So seeing that ford has no real fix for the problem I drilled a large drain hole in the center of the baffle before reinstalling the cover. Also did replace all 16 spark plugs as the TSB calls for and I found the lower 8 we’re all in very bad shape and covered in oil, upper 8 were clean but I replaced them anyway..... Will have to wait and see if my drain hole actually works, my truck was consuming 1 quart every 1500-1800 miles. I will include pictures of the old and new cover so you can see there is no difference.... and I can say I know for a fact the valve cover in my truck was not defective, it was just a bad design from ford, also the pcv on the effected side was wet with oil, other side(drivers side) nice and clean.

New “updated” cover

“Updated” stamped part number on inside of new cover

Old cover, the rust is just from the reused parts cleaner, I hadn’t wiped it off yet , notice my drain hole up the other end in the center of the baffle

Old stamped part number on inside of cover, same as the new one

 

Acon 920.. what year is your 6.2L.. ? Let us know if your "fix" makes a difference..

 

Mine is a 2016, build date 06/15. If this doesn’t work I may just get a pair of the older aluminum valve covers from the earlier years, my last truck was a 2011 extended cab with the 6.2 that had the aluminum covers and that truck did not consume any oil at all, that truck also used 5w20, and the newer years like mine that got the new composite valve covers takes 5w30 which I’ve seen many threads on that as well... I will post back when I have a conclusion on whether or not my little modification to the baffle works or helps at all or not. If it doesn’t I’ll continue with finding a pair of the aluminum covers and if those don’t match up then my last thought would be to add a catch can, if there’s no way to get around the consumption problem catching it with a catch can would be better than recirculating it back through the intake. A big big catch can hahaha

 

I suggest you do a simple way of checking the basics engine health. Warm the engine up to full operating temp and with help block the wheels, remove the oil fill cap and have a trusted person put it in gear and stand on the brakes and give it gas until the motor labors hard. If you can see oil vapor coming out of the cap you have compression leaking past you rings, it will be very noticable if you have a problem. If that checks out you have air getting into the motor letting the pcv system continually draw air through the motor. These new modern motors with all the pollution controll systems have to be sealed or they will use oil. The first places to look is the dip stick and oil fill cap. The motor is always under under some vaccum with less at WOT and the most at idle. If you see a lot of vapor coming out of the cap then you have a serious problem with the basic motor.

I had two 2000 V10 motors both purchased new and one used a quart every 4.5K miles and the other used a quart every 2K miles from new. I never figured out where it was going and the truck was retired at 285K hard miles and it still used a quart every 2K miles (it was my work truck for the first 100K and a friends the rest with all being work miles) at one time it dropped to a quart every 500 miles and it found the fitting on the valve cover opposite the pvc valve cover was leaking allowing air to be pulled through the motor causing more oil consumption.

I don't know about the earlier trucks, but you can't "power brake" (stand on gas and brake at same time) in the later trucks; the power management will dethrottle and limp it. At least my 2018 does this.

 

The last time I did it was to my 03 F150 before I bought it, you just have to give it enough gas to put it under load. I will have to try it on my 2013.
