Broken timing chains - 2011 Ecoboosts
#291
Since all engine manufactures say do not add additives I would suggest using mobil 1 5W40 as a better option at oil drain after motor has had its broken in time on the oil pumps if you intend to use it hard. It would be better suited to deal with dilution of fuel in oil, mho.

The rich mixture has to be harder on the Catz than the motor oil would ever be. I have never experienced any problem with a 5W40 oil usage in summer weathers no matter what the vehicle or intended usage to be..

Oil
I appreciate your posts as it certainly helps us for our own preventative maintenance plan. You are in a unique position as you have lots of trucks and put lots of miles on them so you are doing some beta testing for us.
As a result of your posts, I am switching my oil changes from 10K miles to 7500 or 6000 miles and may have my timing chain replaced at 80K miles. I suspect I have a turbo starting to go bad judging by a "hamster wheel" noise when towing uphill and will have the dealer check that prior to towing season this spring.
Thanks again for the heads up.

I have a 2015 3.5 EB. It is my retirement truck. I read all of these posts with some apprehension with timing chains, DI intake valve coking, and many other issues, but my truck only has about 45,000 on it. Gas mileage isn't that great, but is worst in the winter, at about 15 in the summer and 12.5 in the winter. I have installed a catch can, and based on the amount of crud it gathers, which is easily a pint per thousand miles, which would otherwise get pumped back into the intake, and some of that again becomes blow-by, I would not be the least bit surprised if those running 10K oil changes aren't diluting out the lubrication of their timing chains severely. I change my oil with pure synthetic every 4000 miles. So far, the truck has run great and serves my purpose for what could be my last truck, but this site gives me some jitters.
I get 12.5-13.5 in the winter and 15 overall average otherwise. I have a catch can that catches quite a bit of gunk and the weep hole in my Intercooler.
I change my oil every 3000-4000 miles with full synthetic.
So far, no real issues to report at 18,500 miles.

Hopefully the new 3.5 ecoboost will not have the same problems. That is why I spent 3k more for the 17 over the 16. It looks like Ford tried to fix the problems with the gen 1 3.5s. The extra power and 10 speed are a real bonus too. We shall see.

Next generation went to twin timing chains and adjusters/chain guides and the shutters are great in the grill
