Sorry for the slightly trollish title but I was just thinking. Been running mostly 5w20 in my truck although sometimes I will go with 0w20 in the colder months. Approaching 100k and I do burn about 1qt every 3k miles. Running M1 most of the time and she is smooth and quiet. I have seen a ton of discussion on the truck forums and many people run xw30 in these trucks. Pretty much the same engine as the Boss which specs 5w50. Would there be any benefit to bumping to a 0w30 or 0w40 over my M1 5w20? I'm not thinking the cold performance would be a factor as I'm already plenty covered with the synthetic 5w in my locale but what about running at full temp on the highway or even light duty towing?

Try it and see what happens. Its not going to hurt anything and may reduce your consumption

I have a similar issue in my Tahoe 5.3 with 125,000 miles. Ive had good luck going to M1HM 5W-30. AFE 0W-30 burns off twice as fast.

In a 5w20 engine I'd go to 5w30 before 0w40.

Similar high calcium, higher moly/boron in the M1 and PP 0w-40. Both are in the hths 3.5-3.8 range. Last I checked the add pack in the M1 is a bit stouter. The 0w-40 Edge is a lower calcium, moderate magnesium blend. As far as Euro mfg specs the Edge has more than M1. Some of the PP 0w-40 brews (like SRT) have the fewest mfg approvals. They all go on sale at some point during the year. Let any bottle of motor oil sit long enough and it will probably have some of the add pack settle out.

The recent version of Mobil 1 0w-40 FS starts off with a 12.8 cSt visc at 100 deg C...really in between a 30 and 40 grade just after a little usage. Considering that some of the M1 and Edge 30 grades are in the 11.8-12.5 range....not much different than a 0w-40. Even plain old M1 5w-30 is at 11.1.

M1 0w40 is close to a thick 30 grade. I'd try it just to see if the consumption lessens.

Might be useful to tell everyone the year, make, and engine for your truck, but generally if youve burning a quart every 3000, miles, going up one weight might help.


If you want the job done right......do it yourself.

From his signature... 2011 F150 4x4 5.0L.

Burning a quart every 3k miles? Seems excessive for a 5.0. Try 5w30 or 0w40, but my guess is that won't help much.

Yet another Ford that's been run on 5w20 it's whole life that now has consumption. From what I saw with Crown Vics, consumption will go through the roof by 120k.

Try a run with 0w40, won't hurt a thing, I am betting you will like the way it starts and runs and consumption is likely to go down as well.

I got my Lincoln at 76k I'm sure it had 20 grades from new as well, it uses a little oil (not much, but the only car I have that uses any including a 191k Chevy). I'm hoping I got to it soon enough that it won't increase much.

My thought also.

From my reading on Fords, there should be no issue/damage from changing grades. (agreeing with the Boss reference above)

I thought there another guy on here that was using 0w40 in a similar truck....


I use the overseas owner's manual to choose my oil.

It makes you wonder doesn't it? I made the change from 5W20 to 5W30 in both my Jeeps, and I'm not looking back, even after all the 5W20 success stories I read from time to time here.

OP-Give 0W40 a shot, you have nothing to lose.
