I roughly have 53K on my '15 ecoboost. I'm going in for an oil change next week. Dealership is trying to upsell me the 45K service. They mentioned something about brake fluid flush, crankcase flush, and maybe 1 or 2 other services. What do you guys think? Does that sound legit? Note: My engine was rebuilt at 31K miles.

I would refer to the owner's manual for service intervals.

Some people might not agree about the service intervals in the owner's manual. I'm not sure what to think. I rather not spend 400 extra dollars for no reason, but I want to know whether or not these services are needed. Some people would lean towards Ford service's point of view, some people might lean towards following the owner's manual. I don't know what to think. The service adviser I used to deal with never tried to upsell services, or least I don't remember him doing so. The adviser I deal with now is eager to upsell services. Not sure if he's just being cautious or just trying to fleece me.

what I'm trying to say is some people, not just eager Ford service advisers, would suggest that the service intervals aren't preventive enough, they don't do enough to ensure proper maintenance. Think about how many people followed the service intervals for the 5.4 Triton V-8's and didn't go beyond basic maintenance then sooner rather than later the engine turned into an expensive turd. I'm not saying I agree with the service adviser on these "45K service" items, I'm just saying its frustrating trying to figure out what is needed and not needed.

Ford says to change the oil on my ecoboost every 10k....that's a joke. I'll chang mine every 5k thank you. Lol

Fluids can never be changed too much. The brake fluid and rear differential fluid does break down and pick up deposits...along with the transmission fluid. Coolant breaks down and gets acidic.

Mileage based services are important and are based off the way the vehicle is driven.

My system at work doesn't show major service due until 100k...that's engine coolant, rear axle fluid, and spark plugs. There's no way I'd put 100k on my rear differential fluid...or coolant.

true. and the transmission fluid and coolant were replaced at 31K when the engine was rebuilt in my car. I had the diff fluid changed at 48K. I'm just wondering what I should have done when I go in for my oil change.

The only thing left is the brake fluid.

Why did you have to replace your engine ?

I honestly don't know how it happened, but the engine failed. Ford tore it apart, found a shattered piston, broken rod, smashed sparkplug, and gouged cylinder wall. I wonder if the head gasket failed really bad and caused catastrophic failure. After a week of dinking around, Ford tore it apart and couldn't find a root cause, so they covered the repair. So i just have the brake fluid flushed? no crankcase flushes or oil conditioners, etc. ?

Just brake fluid...with the direct injection in our cars it's a good idea to have an intake service done at least every 30k. Engine flush isn't that important...especially if using synthetic oil.

Our engines pull a bunch of oil vapors into the intake. Those vapors turn into carbon on the valves. Most places call it a de- carb service.

I'm thinking I'll have them do the oil change and intake service but skip the crankcase flush and do the brake flush later. what do you think about oil conditioners? Ford recommended that too

Never used them in turbo cars. My old cars have gotten treatments of Lucas oil stabilizer. That stuff works well with conventional oil in old worn engines. The best products are made by a company called BG. I've used them in a bunch of customers cars that have a little mileage on them. BG also warranties the engine with the use of their products. Good stuff but I've never used it in a turbo car.

I use Mobile 1 full synthetic and change every 5k. The dealer generally uses a synthetic blend oil and recommends 10k between changes.

Honestly, I see no need for an oil conditioner in a newer car. Especially if you use good oil and change it regularly.

I use motorcraft full synthetic, Ford recommends 5k oil changes, same as if you used synthetic blend. of course that contradicts their owner maintenance schedule website, which states oil changes every 10k. I fuel up with chevron 91 only, and occasionally use the chevron techron cleaner in a bottle. I think i might consider having them do the crankcase cleaning and fuel cleaning, but only after they give me exact details about what the services entail. I try to keep my oil changed every 5k. honestly I'm still uncertain on how to fully maintain my 2.3 ecoboost ever since it failed on me at 31k, luckily Ford covered the repairs.
