I've been reading up on diesel engines and how they may require more maintenece than petrol because they need high pressure for firing since they ahve no spark plug and this produces heat which shortens the engine's lifespan. Is this true and would it make you think twice about the diesel F-150?

I don't think this should be an issue with modern diesel engines as cooling systems have improved over the years. They may require expensive synthetic oil and expensive filters but the lifetime of an engine shouldn't be reduced because it's a diesel. then again, I could be wrong.

Here's a piece of article about diesel vs gasoline engines.

Maintenance costs: While Volkswagen, the largest seller of diesel-powered vehicles, has kept its oil change costs close to those for gasoline engines, other makers present a different picture. Fiat Chrysler’s 3.0L eco-diesel engines, for example, require a very specific grade of synthetic oil and a high-priced filter, bringing those oil changes close to the $200 mark at dealerships. Almost all modern diesel engines require synthetic oil and larger displacement V6 and V8 diesels require more than twice the amount of oil as compared to their gasoline cousins. Diesels are now just as complicated and electronically controlled as the most advanced gasoline engines. When they represent a small fraction of vehicles on our roads, how much experience do you think technicians actually get on diagnosing and repairing this technology? Many carmakers now require a very detailed step-by-step process be followed when repairing diesel engine faults under their warranties. They, like their customers, find it expensive when parts are replaced on a trial and error basis.

I guess at least the dealership service employees will be a lot more thorough with a diesel when checking over one if they have a detailed step by step guide. Would changing out the oil yourself void the warranty? From what that paragraph says, changing out the oil is one of the big ticket things you need to do with diesels.

Changing out the oil is extremely tedious. If there going to be anything like the Rams... oh boy.. Its like an hour long oil change.

It's known across the industry that as long as the oil is changed and you have proof of it, that's what matters. So that could be the dealership, some independent shop, a friend or even yourself.

That's all it is. Have proof and log your maintenance and you'll be good to go. Keep receipts of the oil and filter and whatever else you buy.

I was just reading an article about the total cost of diesel car ownership and it may come out cheaper than petrol in the final tally. they may cost more than petrol and maintenance may cost a bit more but you save more on lifetime fuel costs and the depreciation is lower. But this may only apply to second hand F150 owners or those who plan to drive it into the ground.

Which there are a lot of. I've seen a lot of guys driving around old F150s and they're determined to keep it until it blows up lol

That's why some people like buying used diesels since you don't have to wait as long to see a return on your money. Buying new, you have to wait a while for it to really pay off. But it really depends on the individual, some people don't care as much about that aspect.

A lot of people don't really care about it in that aspect. A lot of individuals just want something brand new and fresh. Depending on you're usage of the vehicle really depicts what you'll ultimately end up going with.

Too many things can go wrong with a used vehicle and it may not be covered by warranty anymore. Best to get a new diesel engine and I assume general breakdowns not caused by you are covered by warranty, could even get extended if you want.

Thankfully these days, the reliability of the engines are a lot better than they were before. Majority of the time now you have to worry about something electrical going wrong which I guess is worse because we typically can't fix them ourselves

The infotainment systems aren't cheap to replace... Back in the day most things can be fixed by yourself but with the abundance of electrical in cars these days I'd rather get the extended warranty so the dealership service center can figure it out for me.

You honestly can never go wrong with extended warranty. Can never tell when somethings going to go wrong and obviously we tend to see trends of problems occurring after the initial warranty is over

I think Diesel engines are covered fro 5 years or 100,000 miles. That's plenty of time for things to go wrong and then fixed under warranty for free.

How bad would you really need the extended warranty? From what I can make of these engines overall it seems we could potentially save money by not getting it. But it all depends on the risk someone is willing to take with these.

They have varying plans; 3-8 years, base, premium, etc. Really depends on how long you plan to keep your diesel f150.

8 years being the longest does seem pretty good. The average people tend to keep new vehicles are for approximately 8 years anyhow no ?
