Conventional "RACING" oil or not???

Well I have put nearly 1000 miles on the 73 Yammy TX750 and time for the first oil change. When we first rescued her, my buddy Randy had some Honda JP4 synthetic blend that we put in. Thing is its a 40+ mile round trip to the Honda dealer just to get the oil. I have been eyeballing several "motorcycle racing oils" at the local auto parts. Randy says that due to the balancer issue of foaming up the oil that I should run only racing oil because of the anti foaming properties. Anyone have knowledge of regular OTC oils other than Honda specific oils that will perform accordingly as far as anti foaming goes? Not so much concerned with the synthetic blending or not, just that its a rock solid durable oil for this engine.
 
Go get a gallon jug of Rotella either dino or syn your preference
 
Its not an "OH OH HERE WE GO"....Its a legitimate question. I know less about modern conventional oil formulations than i do about any other subject on earth. The article from a Classic Yammy mag from back in the day ( written by the guy in charge of the recalls and repair program for Yamaha ) stated that had they had "TODAYS" oil technologies back then there wouldnt have been an issue with the oil foaming and loss of engine lubrication. So this has made me ask myself." Just what does he mean by "TODAYS TECHNOLOGY"? I am asking because i want to understand and gain knowledge and not start a pizzing match. Read this article and then answer...

HP...JP....Whatever!! LMAO But yes thats the stuff Randy gave me. So far it has performed well. Like i said, Im no OILOLOGIST so therefore my question.
 
Sorry frank!!!!!

Sorry frank!!!!!

I keep forgetting that there is an "OTHERS" section for this question...SORRY FRANK!!!!!
 
just to add and yes off topic but...
rotella has very little zinc left in it due to cat converters on newer vehicles/government regs and such.
rotella is not even close to what it used to be.
now old stock rotella from several or more years ago...thats a diff story.
brad penn oil is loaded with zinc and is the original Kendall green oil formula.
about 8 bucks per quart to your door...good stuff for sure.
 
So, specifically, do todays modern regular conventional oil stand up to anti foamimg as the thought to be superior "racing" formulas? Whats the specialness of a racing formula made by a motorcycle maufacturer or ..lets say.. Off the shelf auto parts store Valvoline conventional racing oil??? Guess i am trying to sort it out between all the spin doctoring manufacturers claim.

Rotella still has a good bit of zinc and phosphorus - about 1200 ppm. The older formula was about 1500 ppm. Auto oil on the other hand is about 800. Oh, and most modern motorcycle oils are 1200 or less these days.
