I always tip the engine a bit to get the last drops out. It makes a difference!

After draining, replace the oil filter. You might need a special tool for that. Remember to oil the rubber gasket of the new filter before installing it to create a better seal.

23

Absolutely! A good filter wrench can save a lot of hassle. I just did this last weekend and made sure my gasket was snug.

Next, refill with the new oil. Be sure to check your owner’s manual for the right type and amount. Adding a funnel can help avoid spills!

25

So true! And don’t forget to run the engine for a few minutes after filling to help circulate the new oil.

Finally, check your oil level again with the dipstick. It’s not uncommon for the oil to settle a bit after running.

27

Solid advice! I once forgot to do that and had to top off later. Learned my lesson!

28

Make sure to dispose of the old oil properly! Many auto parts stores accept used oil for recycling.

What if you forget to check the oil filter before starting the process? Can it cause serious problems?

31

It can lead to some oil getting mixed in with the old, which is not ideal! This step is really crucial.

32

Has anyone tried using synthetic oil instead of conventional? I’ve heard it has benefits, but is it worth the extra cost?

33

I switched to synthetic a while ago and noticed my engine running smoother! Worth giving it a shot if you’re considering it.

Changing oil on a 3.0 Duramax can be straightforward, but one common pitfall is not using the right oil filter. Always double-check compatibility before purchasing.

35

Great advice! Also, forgetting to warm up the engine a bit can lead to thicker oil that doesn’t drain well.

36

Another mistake is overfilling the engine with oil. Always measure accurately and check the dipstick after pouring in the new oil.

This is so true! A messy cleanup isn’t fun. Anyone have tips on how to avoid spills during the process?
