Unless you can provide data that suggests that extra oil changes extend the life of my engine, there’s no way I’ll do more than is recommended nor will I recommend it to anyone. Keep in mind, mechanics only see the mechanical failures. The only successes you see are with your own vehicles which are almost certainly properly maintained.
The small percentages of failures you see do not related tho the majority of vehicles on the road. Auto manufacturers, insurance companies (extended warranties) and oil companies have billions of dollars at stake in these oil life monitoring systems backed by what I assume is years of data driven research. The vast majority of vehicles mechanics will see are either manufacturing/engineering defects or abused and poorly maintained vehicles. They state right in the owners manual that if you use your vehicle in extreme driving conditions, you need to change your oil more often.
I’ve got 175,000 miles on my eco. Most of it heavy towing. From what I’ve read, There is no fix.
So you recommend the same oil change interval as someone who drives regularly? How do you come up with the 3000 and 5000 mile interval? I’m a data driven person so I’d need to see research that suggests the oil has lost its lubrication properties at those intervals.
I also don’t believe it’s cheap insurance. If there’s a problem with your engine like fuel dilution or timing chain issues, it’s still going to cause problems regardless of how often you change your oil.
You must use the correct oil. Always. Ecoboosts require WSS-M2C929-A ford spec oil. You can’t just put any 5W30 oil in these things. The list of proper spec oil is relatively short. If you don’t use it or get the cheap stuff at the quick lube place you can expect problems.
