I just changed my oil and filter on my v6 2002 firebird and put 5.1 quarts of Peak Performance 10w-30 in.

Was this too much oil? How much should I put in ?

Your engine needs 4.5 quarts of oil only, do NOT drive it till you drain some.
Look in your owners manual to learn how to read the oil dipstick but again do not run this engine overfilled with oil.

They say running an engine with too much oil is worst than runniing an engine with too little.

Even that little bit of oil is too much? Would it eventually burn it off? I drove it around the block to maybe get some to soak into the new filter, perhaps it will go down...

I always try to keep oil level just under full mark. your a little over by 1/2 qt. seems like a lot of trouble, but I'd pull the drain plug and get that oil level down. Could unscrew oil filter and drain that out, might have to do it a couple times, I don't know how much oil your filter holds. could be worst, 2- quarts over- flooding the top half of engine. I've made the mistake of adding too much oil . I maintain 5 diesel engines. they're expensive if I screw one of them up.

yes, too much oil and you could have many failures, you could blow gaskets, oil pump could fail..etc...drain some, and if you need more oil, buy some, trust me, dont make the mistake i made..i blew a headgasket with only about .7 quarts more with my old engine, spend the money on new oil if you have to rather than possibly ruining your engine, im sure you would rather drain some than fix a headgasket, or lower intake manifold gasket...etc, you get the point, hope this helps

Did you check the level after you filled it?

You should ALWAYS do that.

Thanks for all the replies. I will fix it asap. Yes I did check the oil level after I filled it and it was above full. That was with it still on the jack stands and hadn't run the engine yet. Haven't measured it off the jacks and after it run for a minute.

Unless it is grossly overfilled, you should start it and let it warm up while its still on the jackstands, so you can look under it easily and check for leaks at the filter and at the drain plug. Again, ALWAYS do that when you change your oil.

Hmm, I just use a jug of oil and it is perfect on mine. Granted I run a 4.2 V6 filter instead, so thats about twice the filter size of our stocker and I have some oiling mods as well.

I put exactly what the manual says. 4.5. The dipstick still runs high. I drained about half a qt out of it, and it's reading correctly, and better pressure too
My bird is a working progress. New Marshall engine-forged pistons, upgraded rockers and stronger rods/bearings. Rebuilt transmission. New LSD. I wish money grew on trees :)

I did run it on the stands and saw no leaks or anything. Ran just fine, with normal oil pressure. It's hard for me to get a reading on my dipstick because half the dipstick is always covered in oil anyways from it just being wet, so i'm not entirely sure where the real marking is.

Edit: Yes I do wipe the dipstick off, but when I put it back in and pull it out, one side of it is wet with oil from probably the pipe having oil splashed into it, or I just messed up my oil change really bad.
