Interesting Difference in Ford Specified Oils

[Stumpy]

At my previous job we had a 2021 Ford Police Utility Interceptor aka an Explorer with the aspirated 3.3 V6 and the oil cap had 5W-20 emblazoned on it. At my new job, we drive a 2021 an Explorer turbo 4 cylinder that has 5W-30 emblazoned on the oil filler cap. Hmmmmm, guess 5W-20 can't take the heat that an "Eco Boost" dishes out.

Shhhh, you might offend the eco warriors

what is the actual point of this post? You’re comparing a na engine to a boosted one

Not anything new... Been the case from pretty near the beginning of the ecoboost engines.

Police cars tend to be idle heavy

The 1.5T in my Fusion is spec’ed for 5W20. That’s all it has ever gotten and mostly blends as well. Just over 90K so far.

I think it varies.

The 1.6 Ecoboost takes 5w20 I think the 2.0 is 5w30?

My brothers 2.7 Ecoboost takes 5w30

...and in more breaking news! Some cars require 93 octane while others (gasp) make due with.......87.

My old 2018 3.5EB took 30. Figured it was to allow for shearing and dilution.

In 1973 93 octane was considered Regular it had to 95 octane to be premium. They have been robbing you blind for years!

In 1973 I'm sure that 95 octane was polluting the air with lead and making your kids stupid.

Being sarcastic about the BS of the thin oils being as good or better than the higher viscosity oils. Apparently not when you introduce the added heat and stress that turbocharging puts on engines.

My 2020 Ecoboost Ranger specs 5w-30.

Someone needs to put 10w40 in an engine which specs 5w20 and see if it blows up..... or at least give us some oil pressures of each oil cold and hot.

I bet no one will.....

I run a synth 5w40 in place of conventional 5w20. Hasn't blown up. Could care less about oil pressures. I have a couple jugs of 0w40 to run before I can switch to 10w40 or 15w40. I bet my engines won't blow up.

Is this sarcasm? I’m running 5w40 in an engine calling for 5w20 previous fill was 15w40, why would it blow up if not sarcasm

Ford switched a bunch of engines from 5W-20 back to 5W-30 in the last 6-8 years.

I ran my f150 3V 5.4liter V8 (spec'd for 5w20) on 0w40 for over 5 years. Plenty of those engines were run on multi fleet oils for all of their lives that are Xw40 weights. I run the same edge 0w40 in my current F150 3.5 eco and have since its first oil change at 500 miles. Temps below -30C right to 40C in the summer towing through the mountains.

Yes, absolute sarcasm!
