2005 Accord 2.4L - consuming more oil

[buster]

In my last UOA, the report came back with 1.0% fuel dilution. Car now has 109,000 on it. Mostly highway miles. All maintenance is up to date. Even had a valve adjustment.

I have 1,600 miles on Mobil 1 Extended Performance 5w20 and I'm already down 1/4qt. I'm almost positive that the level was full when I did the last oil change, so I'm faily confident that can be ruled out.

The only other thing I can think of is A) time for a new O2 sensor B)changing from reg M1 to EP caused a spike in oil consumption.

Any ideas? I was shocked that after only 1,600 miles on the oil it was down 1/4qt. Normal consumption for this car has always been around 1/2qt per 5k miles. Car is driven at 80 mph for 100 miles a day to and from work. All oils have had the same consumption previously.

1600 miles times 1/4 quart = 6400 miles a quart = NOT a problem.

The time for a O2 sensor is when the check engine light comes on.

Mobil changes their formula more often than anyone else.

I would not even give it a thought.

Take care, bill

True Bill, 1qt per 6,400 can be considered normal but it's not normal when oil consumption is up 40% all of a sudden.

But you don't know *if* it was full at the time. Even *if* it was, are you really going to be concerned with 1qt every 6,400 miles?

I sure would not.

Hopefully you have more important things to be worried about...

Maybe its the Tea?

Take care, bill

I'm almost 100% positive it was full from the last change. My last UOA showed 1.0% fuel dilution which was the highest it's ever been and the car is driven 80% highway.

Tea?

One UOA report of high fuel I would not worry about. Get a few then worry.

No oil consumption problem here IMHO. Must we drive at 80mph?

I have an 02 CR-V with the same engine. It's always consumed a tad bit of oil. Not a lot, but maybe a quart over 3k miles? I have about 100k miles on mine and just recently I got my first CEL, I don't remember the code but I believe it was something to the effect of "catalytic converter inefficiency?"

my last UOA a month ago showed 0.5% fuel dilution. 89K on the car, which is a duplicate of Buster's. This was only the second UOA for this vehicle. Previous one was a year and a half ago at 40K and showed no fuel dilution. Same oil type and driving conditions. Driving conditions BTW are exactly the same as Buster's except it is only 60 miles a day.
Read on this board Terry suggested a FRAM air filter to combat Honda fuel dilution. This is what I am using.

Just wondering, how would an air filter affect fuel dilution? Not that I am second guessing Terry's recomendations, just curious is all.

Time to do the double A R/X treatment!!!

We must.

Restricted intake flow supposedly leads to a rich condition. My 2.4, at 30k consumes nothing. I use 2-cycle oil in the fuel, which may help. My $.02c Buster, is that Mobil 1 burns easily. Maybe it's time to step up to a 30 weight.

I ran Mobil 1 5w30 and 10w30 before. Oil brand has never really made any significant difference in oil consumption. I have to check into other things first see what happens.

The slightest inaccuracy when originally checking the level would result in a major projected oil loss rate.
Also, temperature is important to level checking, especially when it is winter in your area [vs. a hot engine].
A bit more fuel is expected in winter conditions. The fuel injection simulates a choke, and runs richer a lot more of the running time.
I would not like to see any fuel of course, but so far, you don't really seem to have a problem, just the edge of normal running.

Sounds normal, most k-series motors (and the older b-series) tend to consume oil. Might try a 30wt to see if it helps slow down the consumption. Do you do a lot of spirited driving?

 

[buster]

Thanks guys.

""Sounds normal, most k-series motors (and the older b-series) tend to consume oil.""

Let me put it this way, since I've edited the post several times before sending

What are YOU smoking?

Our 140k CRV consumes zero, even 20 weight.

 

[BrianWC]

Weirdness. Mine's always consumed a bit.
