The 2019 F150 isn't on Mobil1's website, any reason I can't use 5-30W M1 EP for this Ecoboost truck?
Good choice. 5W20 is generally put there for fuel economy reasons, that really don't increase mileage one mile per gallon anyways. 5W30 is better for TGDI/GDIs, as many automakers have recommended it over thinner owners manual recommendations in prior years.
Exxon-Mobil generally abides by the owners manual recommendations. Tha't probably why it's not there on the website. Plenty of members here have found better results using 5w30 in that engine.
At $3 per gallon at the gas pump, you may endure a $5 increase when filling-up (very large fuel tank). The trade-off is a better sounding, performing and lasting engine.
Just my opinion, as I know two F150 owners using that engine. One still stands by the 5w20. But he's the type that goes by owners manuals 100%. He even still uses Remington oil, Remington cleaner and Remington 30-06 ammo in his Remington 7400/7600? deer rifle. Yes, he's found better results using my 2nd party ammo, cleaner and oil, but still won't change..... why?..... because it's listed as the preferred choices in that owners manual.
Some folks never change - not even for the better......Whatever!
