Oil Thirsty, About 2 litres of oil every 400 miles? Options

[Ibzy]

I heard that gen 6s are notorious for burning through oil when I got my last one. Is there anything that can be done to improve my oil consumption?

I do about 70 miles a day motorway driving, and the last thing I want is low oil pressure because I forgot to check it this morning.

Cheers

I am getting 1 liter of burn ~1000miles on my 7A engine. I believe that is the norm for all 7A over +150k miles. 1 liter per 400miles seems more excessive.
Do you get blue smoke on cold start ups when the car has been sitting for a coupe days? You can have oil leak through valve stem seals. You may also want to try and do a compression test(which is very easy to do on the 7A), this will also give some idea on the health of your rings. If your compression is low, you may be getting oil seeping thru the rings and being burnt off. I remember reading about someone rebuilding their entire 7AFE, and they still got oil burning...so they replaced the head gasket with a non-MLS to seat the head and block better, and they eliminated the oil burn. Good luck!
