Good Morning all.

I have an 09 FX4 with a 5.4L (15,000 kilometers).

Is anyone using a synthetic blend and are you noticing any immediate benefits (eg. MPG & Performance). Just wondering if the added cost is worth it. Additionally, what brand are you using and /or recommending?

I look foward to all responses.

Thank you.

Thanks for this post.

from my research on the web about this, most synthetics have some sort of mineral oil base to it. now, where the synthetics come in is a huge complex chemistry that fills the gaps, adds a detergent property, & is more tightly controlled so the weight of the oil is more accurate & seems to hold up better over time.

the only drawbacks I saw were older engines that were designed for heavier traditional oils as they get older, there is more wear & will actually use oil & the issues with the seals in the early days (swell with trad oil, retract with syn oil & causes leaks).

The F150 ships with syn blend & is marginally more expensive to buy than reg oil. I can buy the motorcraft blend for less than $3/qt, just about all the stores that have it around here. the 5qt jugs make it a bit cheaper.

I'm not sure myself yet if I want to go Mobil 1 full syn or not, it's about $6.50/qt.
