2004 Buick Rainier Q&A

2004 Buick Rainier Question: Why am I going thru so many quarts of oil lately?

2 months ago I had an oil change at jiffy lube and 4/5 weeks later, the low oil pressure light came on. I checked the oil and found none touching the dipstick. After adding 4 quarts, the dipstick read LOW. That was about 3 weeks ago and now we are back in the same situation but this time the check engine light is on and did not turn off when I added oil. I don;t have oil leaking that I am aware of, no smoking anywhere. The only thing different is when my wife told me that a light was on, I noticed the typical ticking that would indicate a low oil level. Vicdog -
