Anyone else feel an improvement in their 2.7 after the first oil change? Mine seems to be running smoother and MPG seems to be up slightly… Could be a placebo effect.

I have a 21 bronco with 2.7 and i saw a jump in mpg after changing my oil at 1500 miles. Went from 17 mpg to 20. And now in november when in the 40s im at 22 mpg. At 55 devrees and above i can get as much as 24 mpg. I use royal purple full synthetic.Anyone else feel an improvement in their 2.7 after the first oil change?

While the friction may be reduced somewhat due to break-in which **may** lead to an MPG improvement there is NO oil on the planet that is going to increase MPG more than a few tenths AT BEST.So it’s not just me…
