The N62/TU in my X5 has the typical valve stem seal oil consumption. I don't mind topping off regularly, but I want to keep the catalysts alive. I know the proper thing to do is fix/replace the seals, but the car isn't worth enough to sink that kind of money into the motor.
Here's a brief history:
With Castrol 0W-40 I was consuming about 1 quart every 2,000 miles. Not bad, but EDGE 0W-40 has A LOT of phosphorous in it (not cat friendly).
Switched to M1 HM (A3/B3 oil) to try and slow consumption (didn't work... consumed even more), however it has less Phosphorous (~850ppm vs. 1,000ppm)
Next on the list to try is PP Euro L 5W-30 (with a can of LM's ester-based Motor Oil Saver). It's a C3 oil and has about 750ppm of phosphorous. If I can get back to 1 quart every 2,000 miles I'd be a happy camper. Not worried about TBN as I stick to a 5k OCI.
I'll let everyone know how the PP Euro L works out. It's dirt cheap with the Pennzoil rebate ($2.50 a quart), which is nice for a 9 quart sump that drinks oil. PP Euro L is the same as Shell Helix Ultra ECT.
