1.3 quarts of makeup oil, IOLM
I'm pleased to see wear metals continue to drop...although there isn't a lot of room to go lower. This drain interval saw a tough winter combined with a highway trip from Northern Michigan to Western Colorado and back.

This appears to be the drain interval that gets me the maximum mileage without taking TBN lower than I would like.

This engine is excellent. The MI-CO trip was 3795 miles, average fuel economy 18.0 mpg.

Seems like an excellent report all the way around unless I missed something. This report certainly is strong evidence that 5W-20 is not too thin so as to have durability concerns, at least insofar as Ford F150's are concerned. Thanks for posting.

I like the Kendall GT-1. Very good oil.

At work we have a dozen 4.6 modular motors in Crown Vic Police Interceptors. We run them hard for 110k or more, always on 5W-20 oil. We do zero engine work on any of them. The "too thin" crowd is living in the past.

Great report once again.

I see the silicon is still dropping...are you still running the factory air filter or have you dropped in a new one somewhere along the way?

I installed a Fram at 36,000 miles per the maintenance schedule. I think that was way early but I think Ford knows what the truck needs.

Great report - those Ford 5.0's are bulletproof.

 

[steve20]

great reports!

I like the Coyote motor(s) and all of the incredible development work that went into it's design---but I think to be called bulletproof, it'll need some more years of proven durability under it's belt.

I agree. While its doing great at this point, aluminum blocks are still not cast iron. Time will tell.

Man, these Kendall GT-1 UOAs confirm my gut feeling for using it in our mower, and will now be my oil of choice in my focus when it comes time to change again.

 

[BearZDefect]

ConocoPhillips continues to give us excellent lubricants.
Surprise, surprise.

 

[A_Harman]

Excellent lubricants at reasonable cost.

 

[Xtc6k]

Where are people buying their Kendall GT1?
