in other words,buy XOM products,since they use trinuclear moly.
BTW,i am not a believer that their low amounts are truly initially effective unless you've already been using an oil with a good amount of it. for that,they would need about 4 to 5 times as much as what they use.
also,a lesser oil with less amounts can leave just as much,if not more,deposits than a better oil with higher amounts.
Nope. Trinuclear is used by Shell/Amsoil/CP and others. I believe it was made by XOM or Infineum and you don't need as much of it as compared to the type used by some of the Japanese OEM oils and oils like Redline. I'm not entirely sure, but I also think it's more expensive than the other.

for the statement:
"The TEOST 33C bench test evaluates an engine oil’s tendency to form high-temperature
deposits. This test was originally developed and included in GF-2 to evaluate turbocharger
deposits. It was not part of GF-3 or GF-4, but is back in GF-5 in anticipation of greater use of
turbochargers. Turbochargers allow the automakers to use smaller displacement, more fuelefficient
engines while still maintaining high power output. Deposit buildup in the turbocharger
bearing areas can lead to loss of engine performance, turbocharger failure and possibly engine
failure. In GF-2, the maximum limit for deposits was 60 mg. For GF-5, the maximum limit is 30
mg (
except there is no limit for SAE 0W-20 oils because some Japanese OEMs recommend
SAE 0W-20 oils with high molybdenum content which will not pass this test)."
No playbook here.
