My 2009 Impala 3.5 V6 engine takes only 4 quarts of oil when doing an oil and filter change. If I have it changed at a garage they usually overfill by putting 5 quarts in.
yea they average 4 and half quarts , most people just do even amounts dont care about accurate
The next time you have it changed I would tell them to not overfill it.
They actually take about 4.25 qts to be full, so a service shop will charge you for 5. Another example of the oil companies being in bed with the auto manufacturers, the engines should take an even amount, especially when synthetics are being used. They'll charge you another $6-$7 dollars for the qt when you only need a bit more to fill the engine.
