Driven motor oil with oil analysis results compared to Mobil one racing oil showing more wear with much more ZDDP in a Nascar Truck series engine, and also a 360 sprint car engine. When over a certain threshold the package with more ZDDP actually shows more wear than a lesser amount of the same additive in the Driven oil.
More is not better, and actually when it's too much of a concentration it actually accelerates wear rather than fending off wear.
Making your own cocktail of oil additives isn't just as simple as pouring in 4 ounces of a concentrate containing ZDDP, and calling it good. The balance of the additive package is critical. Without doing oil analysis you're shooting in the dark mixing additives yourself. |
Gee, had No idea this thread was about racing engines.
Since the old Castrol GTX days, and the reduction in Zinc, and installing 4 OZ extra in my Drivers, I have had no issues. I did get my oil tested a few times as one of my customers was a oil testing facility when I was working. When zddp first was offered, I used it in synthetic oil. At 15,000 miles used, the oil still passed all tests for its certification.
But, like most folks here in the Lobby, I was , and am not "Racing"
Basically speaking ALL current Motor oils from 5 Winter and up to 40 Summer will be 30X better than the non detergent motor oils of old. .
