Oil recommendation for Chevy LS3?

[mdchaser]

Howdy, I just bought a new Corvette GS with the dry sump LS3 6.2l and would like some input on which oil to use. It has under 2k miles on it and I've already done a few oil changes (don't get started, I know I'm nuts

) so I need to figure out what I'm going to run in it from now on.

I've heard it's good to run a high zddp oil and I ran amsoil in my last vette (though it was limited to 800ppm I believe). I was thinking about running their z-rod oil? I do a once a year change (around 3k miles or less) so cost isn't an issue. Any thoughts or suggestions would be welcome!

Though most of my driving is just around town I do take it to the strip and beat up on it as well.

Any brand Syn oil.

I'd stick with a name brand full synthetic 5W30 until out of warranty for sure.

My preferences - PU5W30 then M1 0W40 once you run out the warranty.

I currently run either T6 5W40, M1 TDT 5W40, or M1 0W40 in my LS2 ... of course I am modified, high mileage, and way past warranty.

Opinions vary ... Good luck!

I'm not terribly worried about the warranty, it's getting a blower here as soon as I can afford it

. I'm just trying to get a feel if there is a stand out product that I may have overlooked. The only time I've ever noticed a difference with an oil was in the transmission of my last vette. I switched to amsoil and immediately received a much smoother shift feel.

Is this one a TR6060, or a 6L80E?

Are you going to build the bottom end for high boost, or just run the stock bottom with a low PSI huffer (and which one/type for that matter)??
(I see you are in the 'Republik' as they say.

Are you going to keep it CARB Gestapo legal, or go the no catcon/metal matrix catcon & longtubes route?)

Amsoil 5w30 signature series would be my choice. but m1 5w30 would be good too.

It's a TR6060 manual which I just put amsoil torque-drive fluid in yesterday. Thanks to the crazies in office here in CA I'm going to try to keep it CARB legal (last vette wasn't even close so I had to sell it out of state, got lucky on that one). It's going to get a low pressure system (most run around 4.5psi) and a z06 exhaust (looks stock but larger diameter) with removable cats. If I end up using a system that taps into the cars oil system I will have to make sure the oil is compatible but the edelbrock blower looks pretty tempting and it's a sealed system so I won't have to worry about which oil I use.

I've got an LS3. M1 5w30 all the way, although RP has recently caught my eye

Nope, they no longer list this in the new Corvette's owner's manuals. They now call for dexos1 instead.
