According to Blackstone, in my engine, the TBN had dropped to between
the 10w30 and the 15w50 at similar or longer intervals. It was not
"cleaning out" my engine, it was losing it's protective qualities at a
faster rate than M1 15w50. It was, however, better than the M1 10w30 at
a similar interval. Were I to switch to Delo, I would run a 2500-3000
interval instead of a 5000 like I run of the 15w50.
