The Civic 'normally' burns some oil and I've been using various 5W20 as Mobil 1 Extended Performance, Pennzoil conventional, Motorcraft 5000, Exxon and the M1 burned the least. The Pennzoil conventional, the worst. I then decided to try the Quaker State Ultimate Durability and see how it goes. It's been over a month now and consumption has dropped. Better than the M1. Now, I didn't do an OCI. I simply topped off. But I've been topping off, less times I NEEDED to. The next OCI will be all Quaker State Ultimate Durability 0W20 and the Civic seems to love it. I'll see if consumption drops DRAMATICALLY. *fingers crossed*
