consumption of the engine oil, or my car is using much than the regular?

Hello,

This engine typically has oil consumption of 1 quart every 2,000 miles.
Anything above is considered excessive.
Most common reason for excessive oil consumption is worn valve guides or worn piston rings. You could have oil consumption without any noticeable smoke out of the tail pipe.
Here is the basic procedure of oil consumption test:

Important: During initial engine break in, it is normal for the engine to use from one to three quarts of oil during the first 3,000 to 6,000 miles, depending on driving conditions.

Check the engine for any external oil leak.
Change the engine oil and filter (four quarts of oil are required to properly fill the crankcase).
Warm the engine up and check the oil level after approximately 10 minutes with vehicle on a level surface. Note exactly where the dipstick reads, relative to the dipstick full mark.
Record the vehicle's mileage, date of oil change and exact location of oil level.
Check oil in 500 miles interval and note any oil loss.
