Exactly. That's the exact reason why I let the car slow down to 50mph on the inclines so that the car will not have to downshift.
Now on the '08 Accord I4s, at least the one that I drove, it downshifted with the slightest throttle input.

I've never heard this, and I am in Western Pennsylvania where we have nothing but hills and mountains that we have to climb to get anywhere, and everything I drive has to constantly downshift. None of my vehicles burn any oil.

If the valve seals and guides are okay, downshifting should not cause significant oil consumption.
What happens if the valves seals are shot, and/or the guides are worn excessively, is that the engine vacuum using engine braking sucks oil in through the intakes. You'll see a bit, or a lot, of smoke coasting down a hill.

If the puff of smoke only happens on startup and goes away it is usually the valve-seals... If it happens when sitting at a light and then goes away it's usually the rings... Sometimes Valve seals but more common the rings at a light...

Same problem.
Closed throttle = high manifold vacuum.
At idle it just sits there in the intake and when you pull out, burns off.
The simple rule of thumb is smoked descending a hill = valve seals and/or guides, smoke ascending a hill = rings.
First scenario is high manifold vacuum, second is low.

How many miles did it have on it when you took posession?

i think he mention he purchased it as new around 7 month ago.

The '08 does use some more agressive fueling and cam timing. Maybe that affects consumption? The HP verion of this engine in the TSX specs a 5w30. If I drove my Accord harder, like w/a stick shift model, I'd skip the 5w-20.
Try a different brand of oil. I know that you get it changed at the dealer but try bringing in oil. My 05 Accord is using 0.5 qrt in 5000 miles on Valvoline 5w20. On Pennzoil YB, it used 1.0 to 1.5 qrts in the same 5000 miles.
Lumpy,
I keep coming back to this post to read only. Now, I have to say that I don't think that any engine,(even Honda) that uses oil in 10,000 miles should be considered "using oil". Or even less miles for that matter on an OCI. I personaly have never gone 10,000 miles on an OCI and I have had Hondas that used oil in 5,000 miles but, I didn't even consider a qt in 5K using oil. That's just me! I would have started out with a couple of shorter OCI's B/4 jumping in the 10,000 miles
Im with the others here that suggest using a different brand or grade of oil or even shorter OCI's. Castrol GTX is a fine oil but, it is only GTX. Maybe try the 5W30! I would let some time pass and see if the consumption continues, she is still a baby yet!
Do/have you driven the Silverado the same as the Accord? I mean that you are comparing a V8 with a 4 banger and although I consider a Chevy engine a little on the loose side and Honda's being more tight, you may have a tighter Chevy and a loose Honda.

80 mph is considering hard IMO. I'm not sure if this applies to the Honda engines, but on my Saturn, if I cruise for long periods of time at speeds above 65 mph, the oil consumption skyrockets. For example, in-town driving would give me an oil consumption rate of about 1 qt every 3k (average). 70 mph+ cruising would raise oil consumption to as high as 1 qt every 1700 miles!
Yeah, most Accord 4 cylinders laugh at 80 mph. Saturn engines are a bit different.
So.... how does downshifting on grades to maintain speed cause more oil consumption? The manifold vacuum drops on open throttle, and is highest on closed throttle going downhill. High manifold vacuum will suck more oil past valve guides, rings etc.
I can see hours of sustained, high-RPM driving causing increased oil consumption, but not the occasional downshift for hills.
Also, if the engine was never driven hard a few times during break-in to seat the rings on the cylinder honing, that can also cause oil-burning or lower compression.
FWIW...most mfgs. consider anything less than 1qt./1000miles to be "normal" oil consumption for most warranty claims.

my 05 Accord 4cyl has been making the trip from NJ to FL 3 to 4 times a year for the last 2 years. Just came back form a trip last Friday. Car has 101K on it have used GTX or GTX/Syntec 5-20 home blend, 5-6K oil and filter (various brands)changes speeds on the trip have always varied from a sustained 70 to 88 mph. Only stops are for gas and food, takes about 18 hours. Average 33 mpg, zero oil consumption for the life of the car sometimes. Maybe his consumption is due to a stacking of manufacturing tolerances?

Char Baby - I did my own service (what I know as a 7500k) and am using the factory recommended 5W20 in Castrol GTX and its going threw about a 1/2 Qt every 3k.
I have not mentioned it but I have been a mechanic for 30 years and several years ago I was Honda factory trained tech at the Honda dealership in Waldorf MD so I do know a lot about the brand. I was just wondering if others have been having issues with their 4 cyl Accords.

Our '06 CR-V (also a K24)doesn't use any oil since it last saw 10,000 miles (currently 50K). It's a manual so I run it through the gears. Currently, using PP 5W-20.
I don't think you will have any warranty issues using a 5w30. Only North American Honda engines have 5W-20 recommended...the rest of the world is specc'ed 5w30.

I have run/maintained several Honda's 97 Accord V-tech 4 cylinder, 2001 Odyssey V-6, 2006 V-tech 4 cylinder, 2002 V-tech 4 cylinder (this one is still new to me, have put 1000 or more miles on it tho) and never had a problem with the motors or oil consumption on any of them. Never had to add any oil between changed, even 7500 OCI. The 97 has started to consume some oil, however I think it's leaking most of that, maybe 1 quart at 5000 mile OCI. The 97 @240k, and 02 being driven at long trip highway speeds of 80 MPH, this does not cause a Honda engine to consume oil!! I would check with the dealership about this, Honda makes an outstanding engine, and I prefer the V-tech 4 cylinder over all others, plenty of power, and great gas mileage.

Lumpy,
As I mentioned earlier, you may just have a Honda engine that is a bit more loosly built than other Hondas, I really don't know! Contact the dealer and they'll probably tell you that it's normal/accepable. And although I mentioned GTX as "only being GTX", I do like it very much, or should I say my engines like it.
I've been around engines since the late 60's/early 70's and everything back then used oil but, some would supprise you and use none between OCI's. As the matter of fact, alot of engines used oil right up until the middle 80's and even today. I understand your concern with it being a Honda but it doesn't sound severe. Honda's have always impressed me with the build quality and engine solidity. Obviously, the rings haven't seated.
My buddy ED,(no longer with us), purchaced new a 97 Dodge Ram with a 360(5.9L) and this engine used oil like a pig. ED only used the truck like a car. Drove the Ram easily and never towed anything. We tried everything(after warranty) including HDEO's and RESTORE right up until we plugged the converter. So, I don't know! As mentioned earlier, try a different brand/grade.
