I have always been told don't over fill the engine with oil. Well, I got the car back from the dealer who put 5 3/4 quarts in when it is supposed to have 4.5. Now, they did change the oil pan so I am sure it was completely empty, but 5 3/4 sounds like too much.
Can this hurt the engine?

 

it depends. If it gets high enough it will foam, and stop lubricating. but it has to be pretty overfilled.

 

I would drain some out.. it's easy enough... then check the level.

 

I know with older small blocks you ran the risk of a blown rear main seal with too much oil in the pan, did that once...oops. Not sure if the LT1 is prone to this as well.

I just fill it up to the top !

 

better yet-
check the level, then drain then check level

more seriously-
mine took a little more than 5qrts
5 qrts + fill oil filter

 

4.5qts is way too low actually. Mine takes 5.5 qts with the long filter in order to show full on the dipstick. I think 5.75 qts is probably safe, but to be sure, check the dipstick immediately after driving the car. If you don't see any evidence of bubbling, you're fine.

 

I use anywher from 5- 5.5 quarts in mine with the K&N filter. But 4.5 is definately not enough should at least have 5. Run it for a while then let it set for 15 minutes or so then check the dipstick. In my opinion 5.75 is a tad too much, but not enough to do any damage.

 

Well at one time I had over 10 in mine. Oil filter got stuck and took some hours worth of work to get off. Well i left for a business trip so my dad was finishing working on it and thought I had already drained the oil but i didnt. Thnak god he only drove it like 10 miles.

 

 

sorry for being an ***, but i would like to know how many quart of oil should i put in my car??

 

I put 5 quarts in mine, and it fills it up to the second to the top hole of the dipstick, so your 94Z would prolly be the same. I run a regular Fram oil filter in mine.

 

Mines took 5 qts as well with filter change.

 

you fill it up only to the 2nd hole? dont we suppose to fill it up to the top hole??

 

I put anywhere from 5 to 5.5 in mine.
