Just got a oil change for my Dads 2006 Luxery III DTS. Did not realize this car holds 8 quarts of oil, is this right??

Check all.fuses and relays associated with your seats locations will be in owners manual.

I would always go with the manual over what anybody else is telling you. But if you want to be sure you're putting in the right amount I find it best to use just slightly less than the quantity given in the manual as your starting point. So since it says 5.8 quarts, I would normally put about 5.5 quarts in. Then start the engine so that the oil gets pumped through everything and you'll get a more accurate oil level reading. Then use the dipstick to measure the oil level and see where it's at. Add more little by little until you're roughly in the middle of the min and max lines on the dipstick.

WELL THE 2.8 ENGINE HOLDS 5 QUARTS OF OIL WITH NEW OIL FILTER. THE 3.5 ENGINE HOLDS 6 QUARTS OF OIL WITH NEW OIL FILTER.

The automatic transmission uses 5.00 quarts (4.7L) of Dexron VI when the filter and pan is removed.
A complete overhaul requires 11.00 quarts (10.4L).

The transfer case takes 1.60 quarts (1.5L) of Dexron III

HOLDS 6.4 QUARTS FOR THE 4.2LITER V-8

4.8 quarts

Hi!!

It holds 7.5 quarts. If you need a copy of your owners manual give me an e-mail address to send it to.

Don't forget to rate this answer.

Hello bhensel: My name is Roger and I will help you. The v-6 engine holds 7qts. with oil filter. The v-8 engine holds 6qts.of oil with filter change. Should you need further help please just ask. Please rate your answer. This way i know it was helpful. Thank You for using Fix Ya. Roger

I see you have a four cylinder since it only holds 4.5 quarts.
2006 manual confirms your oil consumption is within allowances. Just check oil every time you buy gas like the manual reccomends. Do not over rev engine or accelerate from stops at max capacity of car as these can increase oil consumption.

4 to 5 quarts will be sufficient is this vehicle..
