This is the first I’ve heard of 508.00 being formulated for less consumption. Do you have any sources?The VW 508.00/509.00 is supposedly geared toward less consumption.

I've found that M1 HM 0W20 is the thickest of the 20W's (even thicker than 5W20's) at op temp according to specs. Oddly, it's also one of the thinnest at cold temp. I've got nothing to say beyond listing this interesting data I saw.
This. Problem solved.I've had good success with Penn Plat 5w20 and 5w30 not burning. Ultra plat might be a good option as well. The NOACK on the PP is pretty good, so I can only presume the 0w20 would be good.
I've seen this mentioned by others too. Seems it either helps better than others, or actually causes increased consumption. Strange.FWIW Mobil 1 oils have been the ones that I have had the most consumption issues with in my aforementioned Subaru. I have used the following different versions of Mobil 1 0w20: AFE, EP, EP HM. I only bought it because of the rebates but the results of using it were so unimpressive that I don't think I will ever use their stuff again even if they offer rebates.
2014, and the VIN is just outside the VIN range for the piston ring warranty extension. Supposedly this one already has the updated rings. Subaru offered to contribute towards the repair but the out of pocket is still significant.What year is the Subaru?
Then I think the owner will not see a drop in oil usage.Owner only wants to use the OEM specified viscosity.
I agree get maxlife it make my oil seepage to to no seepage at all 2 choice pennzoil high mileageOrdered him a 5-qt jug of Valvoline High Mileage Full Synthetic w/Maxlife technology. Reasons:
1) Major brand
2) Dexos 1 Gen 2 licensed, so seal compatibility should not be an issue and volatility must be below 13%.
3) On rollback to $21.57
Not in my experience although it was only one OCI. My daughter's 2015 Legacy was generally burning about 1/2 qt of 0W-20 at 6k mile intervals and that recently increased to 3/4 qt. I tried Castrol Edge HM 5W-20 and it made no noticeable difference. I have M1 0W-20 High Mileage in it now so I'll see how that goes.I wonder if a 5W20 would burn less vs a 0W20?
My money says likely not half of the people on BITOG are getting that little oil usage from my 3 days + on the forum now. If that car was mine I wouldn't change a thing unless I could find another full synthetic oil on sale with a rebate.Not in my experience although it was only one OCI.

Granted, it does have over 90k miles on it and burning 3/4 quart at 6k mile intervals isn't really that bad. I wanted to stick with the manual recommendation given that she has an extended warranty, but will probably bump it up to something thicker eventually.
I think this one is going thru 2 qts between the 7500 mile oil changes.Not in my experience although it was only one OCI.

Agreed.With that kind of consumption I would try a 5w30 HM oil.

Which was your fave 0W20 in engine smoothness/quietness?I've used 0w20 M1 EP
0w20 M1 AFE
QSUD 0w20 in my 2018 Forester 2.5 no consumption with any oil.
I honestly can't tell any difference between Mobil and QSUD as far as engine performance.Which was your fave 0W20 in engine smoothness/quietness?
