6 quarts? Our cars hold 5. You should be fine with 5W30 as long as it meets the requirements set by the manufacturer. If it doesn't, you could have warranty issues if your motor were to go porous on you.

Royal Purple DOES NOT meet GM4718 requirements last I checked. Meaning it does not meet GM's standards, meaning they can throw your warranty out for using it should something blow on your motor.
LSJ's take 6 quarts
LNF's take 5 quarts.

oh well its full synthetic!? how does it not meet it?! or is that not for the SS sc's? i used 6 quarts of RP in my car last oil change cuz it was cheaper than Valvoline and the other *****

Also just because royal purple will net a few HP in the short term it in no way proves it'll have the same results over a prolonged period of time regardless of what some people wanna believe.
WRONG
Oil is not Oil at all Motul oil is the same as the $2.00 store brand?
Royal Purple isnt a turbo friendly oil apparently, reported to break down way to fast with all the heat
Mobil 1 is much better for our cars, GM Factory fills with it so why not use it?

Get Mobil1 to be safe. Get 0W30 German Castrol if you want better performance and protection (but know wtf you're doing when you look for this, or you'll get shitty US Castrol, which is pointless).
Sell the Royal Purple to some Evo or STI guys at a markup, and laugh to yourself as you drive away.

I wouldnt use Royal Purple... its garbage.
"Other comparative examples of how Royal Purple and Amsoil engine oils differ are how well the oils perform regarding engine wear protection, and the ability of the engine oil to combat high temperatures.
ASTM testing of Royal Purple involved their 20W50 Racing oil versus our AMSOIL Premium Protection Motor Oil 20W50 ARO. The test included 4 ball wear tests with different parameters, a spectrographic baseline, FTIR scan and volatility tests. The Royal Purple showed a significantly high volatility rate with a11.2% boil off rate. This compares to the AMSOIL ARO with only a 6.5% volatility rating. Wear scars were also smaller with the ARO. For example the AMSOIL ARO left a .40mm scar and the Royal Purple oil left a 1.3mm scar. The lower the scar damage number the better the wear scar protection! There was also a surprising difference in the viscosity index. The Royal Purple has a VI of 129 versus 172 for the ARO. The higher the VI, the better the viscosity stays in place at high temperatures.

Fun fact: Amsoil is not a listed GM spec oil. They did not pay GM to get certified for the GM "standard".

sidenote: It never ceases to amaze me how many SSSC owners chime in with irrelevant info on the LNF/Turbo forums.
GC was my oil of choice for multiple cars before the Cobalt. Unfortunately, since it's not GM4817, I opted out. I run Pennzoil Ultra in my TC, which is the same as the Shell Ultra Helix over in Europe. An extremely good oil!

There was a really good post on the Evo forums, from someone not affiliated with any oil, but who did a lot of research. The most telling thing I thought was, no one tried to call him on anything he said (and the AMSoil nuthuggers are pretty quick to do so):

Doh! I didn't realize it wasn't kosher for Cobalts! I haven't switched over, but was planning on shopping for some...notsomuch anymore I guess.

stuffs junk enough said ..
It gives your a HP gain for a fraction of a second and then looses all its viscosity under heavy heat .
Go do some research , lots of guys put this stuff in go to the track and blow motors.. I can think of three 350 Z's with the DE motor that blew running that purple dye junk.
Please if any one can show me that this oil works like it does at 100 miles and the same at 1500 show me the proof.
Just do a a google search for royal purple oil change blown motor and that should answer all your questions.

amsoil? which one of you cobalt drivers use your car as a race car to need amsoil for one. smh this site never ceases to amaze me
ive used RP since day 0 of owning my car, as a matter of fact theres never been any other oil in it except for when it came from the factory with mobile 1 other than that before i drove it any where i changed the oil and used RP and nothing but since that day on
