quarts of oil in an ls1??

5 or 6

don't have the owners manual and it seems like more than 5 came out...

was it overfilled or does it take 6 quarts?

thanks

The manual says 5.5 quarts. I when I changed my oil on Wednesday, it seemed to want to take 5.75 quarts. I filled the filter with oil before I installed it, so maybe that's where the extra .25 quarts went.?.

leave it to GM to make it a pain in the azz like that...

thanks...that actually looks about right...bout a half quart was left after filling the old oil bottles with the used oil...

guess i need to stop and get another quart...:mad:

I put in 5.5 quarts, then after about 500 miles put in the other half a quart. The level is good up until the next oil change.

when I run autocross, and raod racing events I use 7 quarts--don't even bother to drain when not competing, never seem to hurt it. normally I use 6 quarts because you know its going to burn oil its a little over the full line but the LS1 seam to like more oil. Ams oil senthetic

Book says 5.5 quarts. I just add 6 quarts. Half a quart more is not going to hurt anything.

Mine used 5.5 qrts of Mobil ! synthetic...;)

I use the Mobil 1 206 filter which is just a little longer than the stock one and 6 quarts is just right.:)

Five and 1/2 quarts. I'll usually add four, turn the car over briefly and then add what's left. I woudn't use too much more than that as a lot of oil seems to end up in the intake manifold thanks to the sucky PCV design.

I also use the M1206 filter and put in 6qts. Even though I autox, I'm hesitant to put in more. Too much oil and the crank will just turn the oil into a froth and aerate it. That ain't good.

I use 6 quarts too.

That's with the AC Delco PF59 filter.

The LS1 can be overfilled by a half quart with no problems, but if you use the long filter and in that case, you need 6 quarts, but if you use the stock size filter, 5.5 is enough. Alot of autocross guys put in 7 quarts and beat the hell out of their car, and havent had any problems.

Hello Everyone,

Yesterday my Low Oil light came on and I was short about a quart of oil in only about 2000 miles. Earlier today I came on this message board and found an article while skimming through search keywords from what I believe was someone at GM that explained all of the complaints that they were getting on oil consumption and it stated something about the fix they came up with so that people would be able to drive these high performance cars like hard like they should be able to. I didn't get to read the whole article and accidently closed it out and now I can't find it. If I try to use it in search none of the words will match because it was a link. I was about a page long explaining how part of the problem varried from driver to driver (such as if someone else was to use my car in a different sitation that they might not even burn as much oil and went on to talk about something that they replaced with a larger diameter from 9 cm to 14 or so). I appreciate if anyone ones the article I am talking about becuase it throughly explained the problem. I think the person who summited the link had a coment like "this might help...read". Thanks again.

i use 6 quarts every time. heard 6.5 is ok too.
