Currently running Mobil 1 High Mileage 5w20 in a 2008 Honda CR-V with about 138,000 miles on it. Been running the HM since I've been noticing oil loss. On a recent road trip over 1,300 miles, we started the trip with the oil halfway between the 'fill' and 'full' dots on the dipstick (apologies for bad nomenclature). By the time we got to point B, that had reduced to just over the 'fill' line. No harm done. Added a quart, and she was fine for another 1,300 miles back home.

Main question is whether this is 'acceptable' or 'normal' oil loss. I'm tempted to run Mobil 1 Advanced Fuel Economy 0w-20 on the next change to cover the winter, but I don't know whether the HM seal conditioner is what's keeping the thing together. Thanks!
 
I think it depends on what has been typical in the past. Remember an ex-wife's Toyota Celica that used a quart every 1000 miles but that was what it "normally" did, and it continued that way for a long time. I think the issue is whether the usage is increasing at a significant rate.
 
Very acceptable. If I read you right, you lost about 1 quart per 2,600 miles, right? (1,300 miles twice, and 1/2 quart down in 1,300 miles.) Your signature says you're using 5w30. Maybe stick to, or change to, the slightly heavier oil, the "30" for that vehicle with a lot of miles on it.

I have heard the extra seal sweller-conditioners, once you start it on a diet of High Mileage oil, you should probably keep it on High Mileage oil.

You could use the Mobil 1 0w-20 and then order up on Amazon.com a bottle of the respected LiquiMoly Motor Saver, which has seal conditioners, and just use half a bottle in your small sump.
 
The loss isn't entirely consistent per mile. Left point A with oil halfway between fill and full. Checked around 1,000 miles in and found it just above 'fill.' Added a quart, drove to point B, then back to point A (1,600 miles) and saw no loss. But if the overall rate is 'normal,' then maybe we'll just stick with it.

Thanks for the LiquiMoly recommendation. I might go ahead and put that in and see whether any change occurs.

EDIT: Now reading that the LiquiMoly is only used right after an oil change. I have another jug or two of HM standing by, so I'll probably go through those first. Is it safe to assume HM and LiquiMoly can be combined?

High speed driving does promote more oil usage sometimes.
Yours doesn't seem too bad. Lots of cars have a very slight seepage around some valve cover seals, etc., and that's where seal conditioners and slightly thicker oil would help.
About viscosity, I'd be good with using a 30 oil in a car originally spec'ed for a 20 oil, with that many miles on it. (I don't think I'd go to say the very-cool Mobil 1 0w-40 in a car spec'ed for 20 though.)

No. Since the HM already has about the max amount of seal sweller-conditioners in it already, I just don't think it would be a good idea to add LiquiMoly Motor Saver on top of it. From what goes into Motor Saver, it looks like its really an additive which converts any "normal" motor oil into a High Mileage oil.
 
My wife has a 2008 CRV that only uses about half a quart over a 7500 oil change interval. It currently has about 160,000 miles on it. Never used high mileage oil. Has had a diet of various synthetics since new.

You guys are making any excuses you can for that 5W-20.

Oil that thin slides right on past the rings and into the combustion chamber.
 
Everyone gets worked up when have to add oil. Just keep it topped off. All that make up oil(expense) over the remaining life of your eight year old vehicle will not come close to paying someone to tear down your engine.

Except that it usually doesn't. I've run all sorts of different oils through two Honda engines now. The '08 CR-V and '05 MDX in my sig below. Neither one has exhibited any measurable loss of oil, and that was consistent with 0W-20, 5W-20, 0W-30, and 5w30...have ran all four in both engines.

I'd say that consumption this minimal is acceptable...it certainly would be according to Honda's specifications. I once owned two Cadillac Northstar engines...loved the engines, but I had to add a quart every 2-3k miles. Not terrible in the long run -- the oil additive system was constantly being replentished.

Merkava_4, I wish I could blame the Northstar's oil consumption on 20 grade oil, but I can't -- they ran 10w30.

I know, every time I start my car with 5w or 0w it loses a half quart of oil...

10w30 would surely cure that and it's got bigger numbers too......
 
Almost anything can be considered normal. All I can add to this thread is my in-laws have a CRV of 2004 vintage and similar miles and it consumes no measurable amount of oil. Stays full on the dipstick for an entire OCI.
 
Maybe the oil contained a fair bit of moisture and fuel before the trip, which evaporated out. That explains no further oil was used on the return.

Or the ground wasn't level in one or more of the measurements.

Don't confuse him with facts.
