    I've driven this truck for 10 years. I've always put 5.5 quarts of oil in it.


    What is the actual proper amount? some shops occasionally put 6 quarts in.

    What's worst case scenario?

    Check the dip stick. My 5.3 is right in the middle with 6.

    Your manual should say 5.

    Could a quart over cause aeration?


    Cause that would be bad mmk

    Maybe, maybe not. Depends on overall capacity. If the crankshaft is whipping it yes. But I'm not thinking an extra quart would do that with a 5-6 quart capacity.

    Thanks for the quick reply. I tend to get overly anal and concerned about things. Especially now that i've decided to just keep truckin' with this and avoid a car payment.

    I'll just keep doing 5 1/2 quarts like normal.

    Thumbs up!

    I'd still check the stick. If Jiffy Lube slaps a new filter on while it's still draining because they are in a hurry there's your 1/2 quart anyways. I pull the drain plug and filter, go do something else for a while, then finish. I fill the new filter before spinning it on too. I usually put around 5 quarts in, fire it up, turn it off and let it sit, then check and top off. I know that sounds like 8 extra steps but whatever it helps me sleep at night lol.

    Big picture I wouldn't sweat it. A lot of guys hit the paid off milestone and decide they need to fix every squeak and rattle, rebuild the truck from the ground up...I doubt you would be where you are with it if you didn't already take good care of it. My mindset has been something like run it/ride it/race it/fix it when you break it with everything I've owned from mowers to motorcycles.

    5-1/2 quarts isn't going to cause any issues with that 5.7 - You end up around 5-1/2 quarts anyway if you prefill the oil filter at the time of oil change. No worries!

    The manual on mine said 5 qts. I'd fill the filter and then dump the rest in through the oil fill on top of the valve cover. Never had any issues in 150k miles.

    A little extra won't hurt anything. Go too much and you'll probably fill up the PCV and have to clean that out. But 0.5 qt probably doesn't matter.

    My 1990 5.7L calls for 5 quarts of 5W-30.
