I bought a 2017 Lincoln Navigator L

[PWMDMD]

My 19 year old's best friend just inherited a similar Navigator and it's been parked in my driveway every day for the past week and WOW that thing is BIG! It makes my Tundra look like an appetizer and not the main course.

Me: Hey, how's the new ride?

Friend: It's great except a third of my paycheck goes to gas now.

Me: Yup...

Too funny!

It isn't cheap to fill up at the current rates that's for sure!

So far I've put on 3,524 miles in about 45 days of ownership & Fuelly shows 16.2 MPG average. Great for the weight, size, & what it does to haul all 7 of us around on a daily basis. It is certainly a people hauler & not something you'd want to just own for the sake of it for one or two people.

If taking my kids to therapy or Dr appts I get reimbursed $0.70 a mile so that helps.

I'll certainly be testing the oil to get an idea of where I feel comfortable. No way I can change ever 5k, I put on 20k in the last year on another vehicle. I'm in no way saying this is bad advice however. If the timing chain stretches perhaps I'll just find someone to do the job. Anyone know what kind of cost that is?

It's between $3,500 and $5,000. It's a very labor intensive job. Price varies depending on what else you have reolaced. Water pumps, vacuum pump, valve covers, solenoids, etc. Cheaper to DIY the oil changes. There are several Euro full synthetic ~$25 that can be used in this application.

Because this job is very labor intensive no one just puts in timing chains and calls it a day. The other timing components are also usually replaced because you don't want to have to pay the labor twice.

At the end of the day, it's your vehicle and for you to maintain as you seem fit. Oil is way cheaper than paying for a timing job before you need to.

Is the oil to blame or manufacturing not up to the task? Ford's 2011 promo video's showed 162,000 miles of "hard" testing for the 1st gen 3.5L. They must have left out timing chain replacement during those Mike Row voice over video shoots.

Has 5k intervals proven to stop repair or just buy more time? If it buys more time then I'm sort of okay with going longer intervals & having the work done sooner if that adds more wear. Most of my miles are all highway so maybe I can go a bit further than 5k?

Nothing is going to stop the repair because those components are wear items. Earlier oil changes prolong their life. It sounds like you want to do extended oil changes so that is what you should do. Maybe you get lucky and your engine lasts a long time without a timing job repair.

It's just the nature of the long chain. Small wear on each link accumulates and the chain becomes elongated. That's why Ford switch to two shorter chains on the gen 2.

No one can really say for certain. There's not been any quantitative measurement of mileage vs wear. Some people go 200,000 miles with no issues. Some go 100,000 and start having signs. IMO highway mileage is the best use case since most wear happens during dry starts. But if you don't know how much wear it's already experienced, hard to say if you'll get 5k or 50k before you see signs of wear. The only way to know is to check the tensioner by pulling the passenger side valve cover.

Thanks, I'll use the 5w-30 ESP to satisfy the breakdown contract. Otherwise I would've gone straight to the X12 quarts of 0w-40 x4 ESP on my garage shelf. Once the contract us up in 5 years I'll do just that. That would mean I got a good 5 years out of this engine.
