This is straight Maxlife 10w40 with NO additives in my F150 300 cid inline six with 108,528 miles at oil sample time. Oil has 3012 miles on it. Typical driving is 15 mile trips. Had oil pan heater on all cold morning starts. Oil was in since December 20 and was sampled last week. Based on this I am going to run this oil to 4500 miles.

Blackstone comments:

"PAUL: Your first-ever oil analysis looks great! The universal averages column shows typical wear from a Ford 4.9L I-6 engine after about 3200 miles on the oil. Your oil was in use 3012 miles, and your wear levels are reading well below those averages. You could run this oil longer, if you wanted to. We'd suggest trying 4500 miles for the next oil change. Your engine can take it! The oil can take it! Your oil & air filtration systems are working well too--note silicon and insolubles. All in all, things look great. Check back next oil change to establish solid wear trends."

 

Great results! look at the low iron. Higher "friction" (no friction modifers) does not mean higher wear. Thanks for posting. You can easily go six months or 6000 miles on your next run, especially with 15W-40, which has a better additive pack.
