I would not use a racing oil in a street car. It is not API certified b/c it does not have the additive package that you would want.
Stick with a good snthetic such as royal purple or redline, cheaper and will protect your engine better.

not necessary for street car. I know many people use their Pre-Mix on our 8's, not sure about the engine oil

There is no right answer for it.
In order to get API rating, you have to meet some of their requirements, one thing to remember is that, it does not mean the more you have, the easier u will be able to get thru. lets say Certain additives are consider harmful to the earth and you should not have too much in the oil. if you have too much, you fail. Does that mean its bad for the engine ? noooo
Not to mention, it cost money to get the API test, if you know your product works and you have a group of loyal customer, why bother with the test?
So yes You can use Idemitsu oil for a street car. maybe I should be the first one to take that spot.

This would seem to contradict the idea the oil is not meeting API requirements or else they've changed the formulation since. And 'SM' oil is what Mazda specifies except in the USA & Canada (ILSAC only)(ILSAC, API SL or SM in other than USA & Canada)

Racing oils will kill your cat. Plain and simple. If you want a racing oil but would like to spend less Valvoline has a lineup from street legal VR1 to the stuff they use in NASCAR.

I refuse to use Valvoline in a rotary on the grounds that it has the root word "valve" in the name!

savedsol brough up a good question, so I asked Idemitsu about the CAT issue today, they replied promptly....
Your idea of mixing crossed my mind as well, might be another option. Beside when you change/filter oil, you only really change 3.1 qts of 5.6 qts total in the system anyway, so you theoretically never get all the original oil out, short of a complete engine rebuild
