2015 F-150 2.7 EcoBoost Smoke at Startup
Ford documented a startup-smoke concern affecting certain 2.7L EcoBoost vehicles.
Blue or white-looking exhaust smoke on initial startup can have several causes. Ford TSB 19-2188 addresses a specific startup-smoke concern on some 2015–2017 F-150 trucks equipped with the 2.7L EcoBoost, but a smoke colour alone is not a diagnosis.
Smoke after a cold soak can have multiple explanations.
Check the engine and the conditions
Confirm that the truck actually has the 2.7L EcoBoost. Note whether smoke appears after an overnight cold soak, how long it lasts, whether it has an oily smell, and whether it persists after warm-up.
What Ford documented
Ford TSB 19-2188 describes excessive white or blue smoke from the exhaust after a cold soak on some 2015–2017 2.7L EcoBoost F-150s. The bulletin identifies oil entering the left-hand turbocharger turbine housing as a possible cause and describes an updated oil supply tube procedure. The bulletin is not a recall and not proof that every smoky startup has the same cause.
Other possibilities
Normal condensation can produce brief white vapour in cool weather. Persistent dense white smoke, coolant loss, overheating, or sustained blue smoke warrants a different, prompt evaluation. Do not diagnose a head gasket or turbocharger from smoke colour alone.
What to document before visiting a shop
Record the ambient temperature, how long the truck sat, duration of the smoke, oil and coolant levels, and any fault codes. A short stationary video can show the behaviour without needing to drive the vehicle.
When to stop driving
If the engine overheats, runs very poorly, loses fluids rapidly or shows an oil-pressure warning, turn it off when safe and obtain professional assistance.
Next steps
- Verify that the engine is the 2.7L EcoBoost.
- Record whether the smoke is brief or persistent.
- Inspect oil and coolant levels safely with a cold engine.
- Ask a shop to compare your symptoms with Ford TSB 19-2188.

I own a Blue Flame Metallic 2015 Ford F-150 XLT and plan to add firsthand observations, photos and maintenance notes to these guides. I won't present an untested repair as something I've personally done.
