I have around 6k miles on my 408. I dont have any problems with it and it put down 515rwhp on the dyno. I am using mobil 1 5w30 since I put the motor in. I have been leaning toward the GC 0w30 or the royal purple. Just wanted some input on this.

 

ive used royal purple since i got the camaro - runs like a champ. im pretty sure ur gonna get every review possible including amsoil.. so good luck lol

 

I've used GC for about 4 years and 40K miles and I wont use anything else. Very low if any oil consumption compared to others I have used in the past,Mobil 1,royal purple, ams oil....

 

Had to vote GC 0-30w..........nothing else here....

 

Whatever you do just don't go RP - sludge city. M1 is always a safe bet... I just switched to PP 5w30 - quieted down the engine a little no complaints. M1 always served my engine well for its first 116k miles (still running strong).

 

Gc 0w 30 for atleast 15,000 miles and NOOOO oil consumption at all!

 

I would say AMSOIL. used it my t/a have no complaints at all. did amsoil in a couple of friends cars/trucks and fixed some of there problems. i also had bad luck with royal purple. might be the shops fault on that one.

 

AC 5w30

Australian Castrol

 

I voted for GC just to keep this thread on topic haha.

 

I've run RP for a while and it was very clean when I tore the engine down. No sludge, no build up. I will run RP XRP in the new engine.

 

Whats the reason for changing? Have you ever had an oil analysis done?

 

i never had an analysis done. just seen tests that mobil 1 isnt the best synthetic and thinking of changing.

 

IMO,what ever brand you prefer,just use a 10w30.Cold start-ups will kill your engine!

 

RP here and no issues

 

i saw this oil before and i'll run with it , it's more expensive than others but i'll , well i have a question , if the oil viscosity is light or soft it gives more HP's ?

 

It's half the price of Mobil 1 in australia

 

1 liter here about $7

 

Off the top of my head....

Mobil1 - ~$96AUS for 5 litres
CastrolEdge - ~$51AUS for 5 litres

Add $25AUS for a K&N oil filter and its an expensive oil change

None of the above......

Pennzoil Platinum 10w-30 and Amsoil EaO32 oil filter. In Dyson UOA's over the past 6 years, it's outperformed RP Racing 21, Redline 5w-30, and Mobil 1 5w-30 under daily driving and road course conditions.
