What kind of towing capabilities can be expected out of a 3.5L Ecoboost?

The base rating for a 3.5L Ecoboost’s towing capacity is 5,000 pounds. However, it can go as high as 13,200 pounds.

What is the fuel economy rating for the 3.5L Ecoboost?

The ratings for city driving and highway (long-distance) driving for the 3.5 Ecoboost are 17 mpg and 23 mpg, respectively. Another fact to be noted is that Ecoboost engines do not have to be restricted to premium fuel and can adapt to any as long as the octanes do not drop below 87.

What oil do I need to use with the 3.5L Ecoboost?

The highest upgraded 3.5L Ecoboost engine with the V6 model will need a 5W-30 motor oil for optimal performance.

Will my vehicle emit more particles or have unhealthy emissions after the tuning?

There are strict norms in place to ensure that vehicular emissions are not harming the environment in any manner. Therefore the tuners that are available in the market do not tamper with the vehicle’s emissions systems in any way. This ensures that the tuners are legal to use in all the states.

Is there any positive or negative impact of tuning on the lifespan of the engine?

Tuning does not have any long-lasting effects on the life of the engine. The engine’s life is primarily determined by the style of driving and the routine maintenance undertaken to ensure its well-being.

Is it necessary to get any special permission or permit for tuning the vehicle?

It is not necessary to get any specific licenses or permissions for tuning your vehicle. You just need to check whether the particular tuner model is allowed to be used in that particular state. Another thing which should be verified is that some tuners mention that they are designed for racing cars only.

Can I bear down on the throttle all the way to get the same results as the tuner?

This will not yield the expected results as using a tuner. In fact, using the throttle to such an extent frequently will cause more harm than good.

Does tuning have any effect on the frequency of the engine servicing?

As such, the primary outcome of tuning is that the performance of the engine is optimized. There are some modes that put the engine into a high-performance zone, which might lead to a slight increase in the need for an oil change. Otherwise, there would be any significant changes in the frequency of servicing your car.


It should be noted that all the cars that are mass-produced are done so as to be economical and deliver reliable performance to the user.

Having said that, there are some users that would want to break the impositions that are made on the vehicle and alter some engine parameters to customize the car to their own tastes.

Most of the time, these modifications are sought by racers who want to boost the performance of the vehicle and get a higher speed.

Before undertaking any sort of tuning initiative, you should ensure that you are sure about the kind of modifications you want and are selecting the appropriate tuner for it.
