My 2000 EX ate a quart between changes, I just lived with it.My '04 Odyssey with 237k miles is perfect in almost every way except for oil consumption. I never see dripping oil and the undercarriage is clean an dry. I never see blue smoke. However, if I don't top off, it loses about a quart every 5k miles. Thoughts?
awesome advice.I would not sweat 1 qt in 5000 miles. However, I used Castrol 0W-40 to some benefit in an 2005 I4 accord that burned oil much more oil (the I4's are known for stuck oil control piston rings, the V6 not so). Later did the piston soak to get more improvement and reverted to using lower weight oil.
One easy thing to try to reduce oil burn is to add Marvel Mystery oil to the crankcase to replace the missing oil about 1000 miles before your oil change and let it work on any sticking oil control piston rings. Never add more than 1 qt of MMO to the crankcase. Fully fill with oil during the next oil change and repeat the MMO if the level drops in 3-4k miles.
