If you bought a truck to look cool going to the store, I'd agree with you. However my truck does not do short trips. I run long and hard. I have 189K on 2012 XLT screw. It has had nothing but 10k oil changes it's whole life. Has had no chain rattle, etc. etc.

I've read the tests from ASHRAE, and a few others. But several of the tests did not run the truck up to operating speeds for any length of time. They measured fuel pass by the piston at high speed and high torque for a limited time period. I agree the higher the torque and speed, the more the injectors are pumping, but anything that slips by will evaporate given the time to.

Turbo and fuel dilution are not mutually inclusive to DI applications. Most of which has to do with startup open loop programming of which Ford has a TSB to address.

Moreover there are millions of turbo DI applications on the road today that don't experience fuel dilution issues severity equal to the Ford EB observations.

 

Just pointing out what's been stated a bunch if times on thus forum along with many others.

Why take the chance with fuel dilution when oil is so cheap?

I would imagine 90% of the f150s on the road are weekend warrior trucks. Light duty and small projects. Homeowner use. Short trips, especially in the winter are hell on these trucks.

The amount of crap I see in my catch can during the winter is crazy. Almost nothing in the summer.

 

X2!

 

154k miles on my truck with 10k oil changes. I'll keep doing 10k oil changes until I retire it at 250k. no sludge or issues to date, no catch can!

 

I originally was going for 250k, now I've decided for 300k since I'm sneaking up on 200k now, and I still have 3 years before retirement.

The difference between amounts in summer and winter is the temperature delta between the internal engine and the external ambient temp.

Taking gases from a warm environment and moving them to a cooler environment causes a state change from gas to liquid. If these substances were left inside the engine system much or most of it stays in a gas form. Thus why EB engines that don't have a catch can, don't have pints or quarts of liquid produced.

In winter since it's colder than summer, the temperature drop is greater from engine to ambient air, more gas will be converted to liquid.

 

Yes, same problem. Started about 85000. My mechanic tried but this is a tricky one. Timing chain is good. Im gonna pay ford for a diagnostic . We started with least expensive 1st. Were thinking some sort of sensor or vacuum leak. Idk. No recall that i can find thats related. I sure hope you got your money back for the timing chain. At 1st thats what we were thinking. No noise. I will let you know what i find
