Diesel engines need more maintenance?

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.

Quote:
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 Chryslerís 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.

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.
