High Mileage synthetic oils

Do they really make a difference and why? I'm on a 5k oil change interval, and I'm burning about 3 quarts now between changes. No signs of leaks. 172k mi, 525it.

A little excessive, but not terribly: the six is an oil burner.

I've not seen high-mileage "synthetic" oils. Might try a fill. Report back.

Might also check your crankcase vent system for failure. A bad CCV will cause high oil consumption. Search here for diagnostics.

My 528i burns one quart in 6k @ 120 k miles on Mobil 1 .

I do use Mobil 1 extended mileage oil ( has additional additives to go 15k between changes) in my 140k Jeep v8 .... Burns 1 quart in 10k .

I also use the extended mileage in my wife's Miata with 80k .... It is an oil burner @ 1 quart every 2 k .

All cars are original owner vehicles with documented oil changes since new. All grew up on Mobil 1. All will go 200k before they get the pink slip . Our last Miata ( '90) went 260k on Mobil 1. No engine issues so far. Makes me a believer .... Mobil 1 extended ( gold bottle) and Wix / Purolator filters ..... Cheap insurance .

My M54 engine burns 1Qt between oil change. I've just tried High-Mileage Mobile1 Synthetic 5W-30 for the last oil change. Will see how it does.

May I suggest using a thicker weight oil to compensate for wear? A thicker weight oil, such as Mobile 1 15w50, should reduce oil consumption between oil changes unless it's a faulty CCV, stuck ring due excess carbon deposits, or bad valve seals, from what I read online.
http://www.mobiloil.com/USA-English/...duct_Guide.pdf

A leak down test should be able to determine which cylinder's may have a piston ring issue. You may want to also try using product like Seafoam, B12 Chemtool to desludge your engine prior to changing the oil, this may help clean out the CCV.

Bavuto.com sells a LubriMolly flush and fuel injection kit you may also want to try.

Like many here are saying, definitely service your CCV/PVC system.
3 yrs ago, my 528 was using up about 2 qts in between a 5k mile oci.
I replaced my CCV, cleaned out the ICV w/ carb cleaner to free up the ball valve, and replaced all hoses surrounding the CCV, including the hose that attaches to the oil dipstick tube and oil pan.
Since then, the oil consumption has disappeared completely. Went from burning up 2 qts every 5k miles to zero oil consumption since doing this. 20k miles so far and no oil loss. 0w-40 mobil 1.
