Hyper-Miling the FR3

OK, here's challenge.

Throwing it down, who will find the biggest MPG improvement this season.

Here are some ideas - of course YMMV.

Rear World of Outlaw Wing.
Block off front grill to improve airflow across/through front cap.
Repurpose useless fog lights as air scoops for engine cooling.
Helium tire inflation.
0W20 Synthetic Motor Oil
Synthetic Trans Fluid.
Synthetic differential fluid.
Synthetic oil filled wheel bearing kit.
Synthetic steering fluid.
Synthetic freon.
Synthetic windshield washer fluid.
Synthetic brake fluid.
"Moon" style aluminum wheel covers.
Remove useless side mirrors.
Side skirts along side bottom of storage bins.
Pointing the generator exhaust to the rear utilizing lost side thrust.
Running one of the dual rear tires with just a space saver spare, reducing rolling resistance.
Installing a AC clutch disconnect to reduce wasteful parasitic HP loss.
Brake pad gap actuators to eliminate pad friction.
Full under body fairings.
Replace energy wasted by shock stiction/movement by replacement with solid metal struts.
"Inertial" 40,000 rpm steel flywheel to capture energy when descending hills.

What did I forget?

Install an Electric-assist motor after the transmission, a few more batteries to collect the regenerative power, from the drivetrain. In essence, make it more hybrid power!

I found the best way to get good mileage is to just leave it in the driveway.

IDK but towing a car trailer with a 2 door Jeep on the trailer I seem to always see 6.8 up to 8.2 mpg's and I keep the RV glued in the right lane and roll along at 62-64 mph.

If money is no object, I would install headers like Banks PowerPack below.

49384 PowerPack Bundle, Complete Power System for use with 2016-17 Ford 6.8L Class-A Motorhome, Right Exit

I might be able to afford the chrome exhaust tip.

I covet that Banks kit, and it's on sale right now!

Something tells me I would be using the throttle too much to hear the roar of the v10 scaring the wits out of small animals and children.

The more I think about it, the better it sounds regardless of the cost of loss of mileage.

This ain't no RV, it's a V10 Formula 1 RV!

While I am dreaming, anyone ever thought how cool a FR3 would look with funny car style 5 pipe upturned exhaust system sticking out of both sides in front of the rear wheels?

How about a shark tooth paint job on the front grille?

Someone talk me down from the ledge already.
