Topic: Normal oil use rates

[Lewis Hein]

Hi all,

After a little under 2000 miles of use, my Toyota 22R has burned through about 1/2-1 quarts of oil (not synthetic or anything -- just ordinary 5W-30 motor oil from NAPA).

This seems excessive to me  -- a figure appropriate for an engine that is worn out. What's even more confusing is that this engine produces decent power and gets a steady 18 MPG on a mix of city, highway, and dirt road driving.


Thoughts, anyone? Am I just paranoid? What do your engines use at what mileage?

You sure it is getting burned or is it coming out somewhere else? E.G oil pump seal, front main seal, rear main seal...  Do you notice any oil spots where you park it?

[Lewis Hein [OP]]

No, no oil spots where I usually park it. Even though the oil pan gasket is known to seep, the lack of oil spots means this isn't a big loss. The only place I can think of that the oil is going is out the exhaust pipe.

Probably leaky valve stem seals.

My '80 will burn a quart just driving to town but it still has pretty good power.  It's an original engine though and the seals are petrified.

I would replace valve seals if I were you but don't stress about it.  Also is the PCV valve OK?

[Lewis Hein [OP]]

Forgive my ignorance -- what is the PCV valve? I can't think of any acronym that fits.

I change my oil every 5k miles.

5 qts with change,    1 - 2 qts added before next change (then I'm low when changing oil)

It's been like this for 'like forever'........

[Lewis Hein [OP]]

How many miles on your engine? I.E., is this oil-slurping behavior indicative of a rebuild in the near future?

[emsvitil]

I have 173k

190-195 psi compression test

all cylinders < 2% leakdown test



I think you're fine from an oil viewpoint........

I agree... that seems to be in the ballpark for 22s over 100K miles, but it depends.....
