76 high performance,any opinions?

[tonttu]

i was thinking to put 76 high performance dino oil in my 92 v6 firebird,112500 miles on it.
any thoughts about it? im thinking to use 10w30.
would it be thicker than some other 10w30 because its like racing oil,or something? i dont have turbo in my pontiac,or any other modifications.im thinking that is it ok to use it normal sport car like firebird,or would it be more better for racing cars or racing use only?
my two choices are gm oil,or 76 oil.any suggestions?? thanks. [img]smile.gif[/img]

racing oil would normally have a higher viscosity to handly the high temps and revs of lets say a Indy car. if its still a 10w -30 u should be fine, but i duno if its worth it depending on the cost. all sae and apd ithink aproved oils will have additives to help the engine run good and detergents to help clean it. the regular stuff would be fine.

but no harm if i use it in street car like my firebird? and its 100% dino oil,all three grades,10w30,10w40 and 20w50?
