The exact amount is however much it takes to reach the full mark on the dipstick. How much you are able to drain will also effect this, if the car is not level (like changing oil with only a floor jack) you aren't going to be getting every last drop out.

Having said that, the owner's manual states 5.5 quarts, but I've always had to use 5.75 to reach the full mark on just about every LS1 I've owned. I don't know why.

Some people use a larger oil filter than stock, and this will also require a bit more oil.

5.5 quarts here as well on level straight ground with a standard GM or Wix filter. I can't imagine 7 quarts in any scenario. That could be detrimental.

For oil and filter change I use a 5 liter jug and about 1/2 of a quart. I use a floor jack to get the plug and filter out then lower it to get the most oil out.

Depends on how you do your oil changes. Quicky lube, it'll take 5 new qrts and it will have 5.5 qrts in the entire system when they finish. All the old oil will never have time to drain out of the engine, about a half qrt will remian, maybe more. If you do it as I explained in the other thread, you will drain "almost" every drop of old oil out and then you should put 5.5 qrts of new back in. The system was designed by GM for 5.5. Almost everyone I know puts in 6 when they do an oil change. Can't hurt anything, minutely helps cooling and if you burn 1/2 - 1 qrt between oil changes....now you won't run as low when it gets closer to oil change time.......it really makes no difference at all if you use 5, 5.5 or 6. All 3 will work the same.

On ls1 vehicles, the amount of oil largely depends on the size of the filter being used. I'm not really a fan of this idea as the larger oil filter for our vehicles sits like 1-2 inches lower than the oil pan.

Back when I used to change oil for a living, I found that 95% of the time the specified oil capacity in the service manual (Mitchell on demand, all data, etc..) doesn't reach the full mark on the dip stick. A lot of those instances also allowed a few minutes for the oil to drain down into the pan for a better reading.

I completely agree, I do 5.5 with a cheap AC Delco filter since I change it out every 3k anyways. Pretty sure as long as you don't put in too little or too much, it will be fine.

The actual fill is 5.5. 5.75 puts it at the top of the stick, 6 gives you some leeway to burn a little until next service. Between 5.5 and 6 is money. AC delco filters aren't "cheap" compared to most of whats on the parts stores shelves. I use them on all of my cars and have never had any oiling/filter issues.
