</font><font color="blue" class="small">( My statements were based on spectro and ferrographic analysis results using this oil. The only problem is comparing the two as we changed to Predictive Maintenance for our lab midstream. )</font>
Well kindly post the results then.

Again we are talking to different classes of oil here. Your delo and delvac are not ester nor PAO based and only a group 3. Just going by TBN and ZDDP, the oilsyou use have less; hence less protection. Are they good oils sure but when you compare to a higher group…well things go south.
</font><font color="blue" class="small">( I'm a dealer for Amsoil (isn't everybody) but am open minded in my choice of oils based on the insight of my friend George at
www.avlube.com and his wealth of knowledge/experience. As for the 4 ball test that Amsoil likes to use, I am told that this test more closely assimilates the sliding action of a hypoid gear than any force in an engine. )</font>
Uh, not everyone is a dealer. Take away the four ball and look at the Noack Volatility, for example. Mobil is over 16 and Amsoil 6. You need or use more oil when using. I could go on and on but just look at the test results. Also you friend at avlubes is an ExxonMobil Distributorr…go figure
</font><font color="blue" class="small">( I'm far from an oil expert in terms of PAO, esters, etc. All I know is that my truck runs at 500+ RWHP, and over 1000 lb/ft of TQ at the wheels, and Delvac 1 at 7-8k intervals is doing the job better than the Amsoil 5w30 did back when I was in the low 300HP range...)</font>
Goes back to my first post/reply. I find that very hard to believe since the add pkg alone is very different. This also goes back to my #2 reply.

Delo has a god base stock.
Delvac has a better additive package.
