here is a pretty good read

--Important read-- Engine Oil Tech - Corvette Forum

LG no longer recommends Mobil 1

They recommend 2 of the oils I stated :) and also talk about what I've been saying. Amsoil, redline etc will protect the engine under hard driving situations where Mobil 1 will not.

Lifter problems are usually the result of ZDDP and in all honesty you don't need very much ZDDP in oil for a motor like a 350Z/370Z since its a DOHC design.

M1 5w-30/0w-40 (depending on cylinder wall design) is the #1 Race oil ran every weekend by professional race teams. 5w-30 M1 is what Roush Yates uses in and recommends for their motors including the Grand-Am DP motors that run on it for 24 hours strait. So saying it doesn't protect under hard driving situations is pretty laughable.

5w-30 M1 is what they run in the Doran 370Z and they have had Zero failures as the result of oiling.

Also, I know for a fact that when run on the Dyno M1 (5w-30 and 0w-40) make the same power as basically every synthetic on the market in a 370Z within 1/2 a HP to Amsoil/Redline/Motul/Brad Penn. They have all been ran on the Dyno with basically no difference in power.

I shouldnt have said it will not protect under hard driving i meant it wont protect as well.

Im not trying to argue about proven tests that clearly show Amsoil being superior, people will run what they want but some oils are better then others.

I run Royal Purple 5-30 in my Nismo and have run Royal Purple in all my drift/race cars, and my other vehicals trucks and such, but never for my WRX.

I also change my oil often usually just before 3K, and if I know it's going to be a hot weather event I'll change it out before.

Moble 1 sucks in my opinion, I have used it quite a few times and hated it. I wouldn't put it into any of my cars even it if was given to me.

I heard good things about Eneos, Motul, and Red Line, but never have tried them.

I pitted for dirt modified race team for a few years, and all they used was Red Line. We also changed the oil after every race.

How many people are running Amsoil?

I've pretty much always avoided Amsoil precisely because of their MLM model of business. I know zero about how awesome (or not) the oil is. It might be the single best-engineered oil on the planet for all I know. But my gut says stay way from MLM-ish stuff in general, and every time I see someone comment positively on Amsoil anywhere, I have to wonder if they're a dealer...

The only thing I have every used in the Z, car has a 112,000 miles on it and still runs like a champ. Since the Z is only a track car now, switching over to thie, AMSOIL DOMINATOR® 10W-30 Racing Oil

Even when the car got tuned, the tuner said it was one of the stronger motors they have seen with that about of miles on it. So I am sold

I switched to Dominator when I saw the extreme temps that my oil sees on the track.

To the OP - I'd suggest you get an oil analysis on whatever oil you choose. Or a Dyson analysis for even more detailed information. You are probably good with any named synthetic oil, and make it a practice to change it after a track day.

To the OP- I would definitely get an oil cooler if you're going to track your car. The stock 2012 oil cooler is insufficient for track duty. It's barely passable for hard street use.

There are 19, 25, and 34 row coolers that are out there. If you're going to track during the summer months, I would definitely go with the 34 row.

As for oil, if you stick with a synthetic and change it regularly- you'll be fine. If you want to spring for the expensive stuff that's ok, but Mobil 1 at Costco is super cheap and it'll work for track duty. Getting an oil cooler will enable your oil to last longer between changes as well.

Liqui Moly or Mobil 1 0w-40

Amsoil=Scientology......:icon23:

Ok, I'm going to install my new oil cooler next oil change and am going to run AmSoil, What weight should I get and should I get that Dominator oil? or just stick with regular AmSoil?:tiphat:

Anyone??

I would stick with the weight recommended. I would not use the dominator if this is a street car, but you would have to do some research. I use it, but it will get replaced every track event, my car is track only and has no cats. Not sure you will get the miles you want or if it will harm you cats.
