I live in Wisconsin 93 octane is what I would use stock block for now and I was thinking about ams oil 20w-50

 

^^^get thinner oil man like 5w30 its cold up there.

I just switched to Amsoil from BP....not because of the oil but rumor has it that BP might be closing up shop soon. So i had to find a good alternative....i like the amsoil so far tho.

 

umm thats wayyyy to thick for Wisconsin winter, let alone a stock block use that oil and ull have a build coming very soon.
get some 5w-30 or 5w-40

 

What about the 10w-40? I am tring to get one the fp approves incase something happens to the turbo under warrenty

 

This is straight off FP's website... I would rum AMSoil!!!

 

I run Amsoil for my jdm blinker fluid

 

Thanks for the info. I'm new at all of this

 

That's some expensive blinkers fluid!!!

 

I am sure people will bash me for this but yeah stock blocks aren't made for 20w50. To thick and there is a good chance motor will go due to lack of oiling. Clearences aren't that loose. 5w30,10w30 are about what you should use as someone already stated. If you had a built motor and your tollerences weren't so tight then yeah sure you could get away with a 20w50 just not a stock block.

 

The only differences in clearances between a stock and a built block is the piston ring end gap, everything else is the same.

A straight 20-50 is too thick for an evo motor that gets a lot of daily miles on it.

 

Penn near me is becoming increasingly difficult to find. I switched to Valvoline VR1.

 

Good choice, it's what I run. UOA's come back great. I've heard that Brad Penn is going out of business..

 

True but not true, some people like to run different bearing clearences or if the block has to be line honed or whatever because of bearing failure. I'm sure they would run or try to run the same tollerences, but thats not always the case. But all in all I agree.

 

Ebay ftw. You can usually get a case of it for right around 75 to 80 bucks. The vr1 oil is a good oil I ran that before I switched to Amsoil and not Brad Penn.
