This is because oils like this have additives such as zinc with acts as a facilitator for friction modifiers to bind to surfaces. On-road oils don't because off-road additives such as the aforementioned zinc and even sulfur (which was banned by the EPA in 2006) "might" damage the catalyst in a catalytic converter. So with off-road oil such as this you'll have better friction modifier (usually moly), etc. biding to surfaces which is good but because it binds better and because it's only intended short frequency changes racing oil like this one isn't good for your daily driver. Oil shear and oil traction is going to cause your this oil to be worthless a lot faster in a daily driver and the traction will lead to cam galling quickly especially in a solid lifter application but also in a roller lifter motor. The racing oils also tend to be high in phosphates which is god for a racing engine where bearing wear is not an issue (frequency of engine rebuilds) but in your daily driver your just going to murder your bearings by running this oil. Tribology (friction/lubes) is my area of specialty in mechanical engineering and the above is a pretty lay-man explanation I can give details if anyone has a question.
In short: don't run it in your daily driver just 'cus it says "racing" on it doesn't make it better for your car.
