My engine was not built to factory specs. It is not a all out race engine either thou. It has forged rods and forged pistons on a refurbished stock crank, ported heads and a LS6 cam. The builder told me that it was built to looser tolerances than stock. Is this enough to make the 20W50 a good...

I just got my first UOA back on my rebuilt LS1. The motor had 1,300 miles on it when I put the S2K in. I ran the S2K for 3,478 miles. Looks to me like things are ok with it. Here it is for comment: Mike

Interesting reply. I went with the 20w50 based on recomendations from here. I'm not opposed to running the 0w30 if it is the right choice. I run open track events thou not AutoX. Typically Willow Springs or Cal Speedway.

I have no idea where they came to that conclusion. Perhaps the S2K racing is basicaly the same as their diesel oil. I did run 1,000 miles of dyno oil before switching over to the S2K.

It just kinda felt funny pouring stuff that looked a fair amount like ATF into the crank case.

Thanks. Actually I signed up just before I started reading this site. Wish I would have found this site first. My upline is like a hundred years old and doesn't care/know much about high performance stuff. He is convenient since he is in town and he stocks a fair amount of stuff. Think I would...

I just got a case of S2000 20W50 in one gallon bottles. I was kinda freaked out to see it was red like ATF. Anyone know why it's red? Mike

Ok, I missed checking the box this time around.

Speaking of pressure what kind of pressure do you see on the stock gauge at hot idle? Mine seems to be around 20 most the time at idle. Not sure what it used to be as I didn't pay that close of attention. By the way is there a way to have this board email me when a thread has a new post? I...

I am not certain myself, but he did say the pistons had a bit more clearance than stock. Which would further reinforce the idea of the S2000 20w-50. I want to add a Accusump and aftermarket pressure and temp gauges as soon as funds permit. (likely a cooler too)

Thanks for the imput guys. So run dino oil for another 1000 miles or so? I will be taking it in for dyno tunning after 500 miles or so, should I wait till I put in syn to have the dyno tunning done? Pablo, you don't think 20w50 is to thick for street use? If I was still going to the track 1 -...

The shop said it has a "break in oil" in it and to change it out in a couple of hundred miles. I ran Mobil1 in it before when it spun a rod bearing. I don't think the oil was the problem. Mark blames the stock rod bolts and the 5,000 - 6,000 miles on road race courses in the last year or so...

Well I picked my car up tonight. I'm planning on running Amsoil in it. Should I run the Series 2000 0W30, Series 2000 20W50(I think this is to thick.), ASL 5W-30 or ATM 10W-30? I just had the motor rebuilt 10/1000 over (IIRC min over bore) forged pistons, forged rods, stage 1 heads, LS6 Cam. I...

Just another example of why I hate dealers. The only way any of them stay in business is that most all of them are the same.

The Camaro is one of the best handling straight axle cars you will find for the money. Since I don't have a money tree that's what I drive. You can make a Fox body Mustang faster but it will cost you $15K - $20K in handling mods to do it. I am 99.99% sure the rear window on the Z06 opens up (as...
