Owners of other similar General Motors vehicles with the LZE 3500 or 3.5L engines such as the Monte Carlo, Buick LaCrosse, Allure, Pontiac Grand Prix, Chevy Malibu, Saturn Aura, Pontiac G6, and Saturn Vue may also find this guide to be useful.

To complete this oil change, you'll need 4 quarts or 3.8 liters of new SAE 5W-30 weight oil, a floor jack, jack stands, a funnel, an oil catch container, a 15mm socket or wrench, and a Lisle 63600 oil filter wrench.

Some compatible oil filters include the following: K&N PS-2006, Mobil1 M1-206, ACDelco PF61E, Purolator PureONE PL25288, Purolator L25288, Fram PH9837 & Bosch D3423.

Then turn off the engine, put blocks behind the rear wheels, jack up the front passenger side with the floor jack and secure it with a jack stand or two.

The 15mm oil drain bolt and the oil filter are located near the rear of the engine's underside closer to the passenger side.

It was relatively easy to spin off the old filter by hand, but it's always a good idea to have an oil filter wrench handy just in case.

Allow the old oil to drain out for at least a few minutes.

Take off the oil filler cap to allow air to enter the engine and cause the old oil to drain more quickly.

Once the old oil has drained out, replace the 15mm drain bolt and tighten it just past hand tight.

Don't over tighten it or you may damage the aluminum oil pan or the threads.

Move the oil catch container forward under the oil filter and then twist off the filter.

If you have trouble removing the old filter, use an oil filter wrench such as the Lisle 63600.

Some oil will leak out of the old filter.

I recommend buying either the Mobil1 M1-206 or the ACDelco PF61E oil filters since they have excellent reviews on Amazon.

Before screwing on the new oil filter, place a thin bead of new oil on the rubber o-ring at the top of the filter.

This allows it to create a better seal and makes it easier to twist if off during the next oil change.

Twist on the filter just past hand tight.

Do not use an oil filter wrench to tighten the filter as it may cause damage to the oil filter and cause it to leak.

Then run the engine for a minute, shut it off, let it sit for a few minutes, and check the oil level on the dipstick.

Keep adding a small amount of new oil until the level on the dipstick reaches the "Full" mark.

The GM 3500 LZE 3.5L V6 engine's capacity is 4 U.S. quarts but you may need less than that depending on how long the old oil was allowed to drain out.

It's easier to add more oil than it is to drain it out if you've added too much.

It's also better to run an engine with slightly less oil than required than to have too much oil in the engine which can cause damage to the seals or gaskets and create oil leaks.
