Not a question but a statement about my 2005 Impala LS, 3.8 V6

What is your question?

Bought it new and it had perfect maintenance. I drove it until 2016 and gave it to my son with 270,000 miles and that was 3 years ago and he still uses it as his daily driver. Uses .5 to .75 qt. of oil between oil changes at 5,000 mile intervals. It has been on Mobile 1 synthetic since the 1 change when new. Take care of them and they will last a long time. Sully
