I have a 04 2.4 4 cylinder camry solara since new. Up to 140,000 it never burned any oil. Now every 1500 I need to add 1 quart. It does not smoke. The performance and gas use is the same as always. Should I just add oil or change it every 1500 miles? I wanted to take the car on a long trip 1200 each way. Anyone have any ideas?? THANK YOU

 

The car now has 152k and burns 1 quart every 1k miles. What can I do to save the engine??? Thank you

 

Assume you checked for oil leaks.

Check the engines PCV system for plugging (if it has one).

Remove the plugs and determine if one is different in appearance then the others oil due to higher oil blow-by in that cylinder.

A compressor or leak down test may reveal compression issues.

This engine does have issues with high oil consumption apparently due to piston rings problems.

And the head bolts can pull out of the aluminum block.

Suggest having a good mechanic look at the engine.

A sudden change in oil consumption typically indicates the PVC system plugged up, a more serious oil leak, broken piston ring, etc.
