Engine Protection
What It Does
Better Fuel Economy
Get more miles out of every tank — measurable gains you'll notice at the pump.
Smoother, Quieter Running
"You'll feel it before you can explain it." Less vibration, less noise, more confidence.
Less Wear, More Years
Protection that compounds over time, not just one tank. Every treatment adds up.
Performance That Comes Back
Closer to how it felt on day one — restored responsiveness, reduced sluggishness.
Works Across the Board
Cars, trucks, boats, sleds, and the equipment in between. One formula, all engines.
TuneUp 66 Engine Armour works with the oil already in your engine — no drain, no special tools, no guesswork.
Engine Protection
Real Drivers. Real Results.
Simple by Design
How It Works
01
Pour It In
Warm up your engine for 10 minutes first
Works with the oil you’ve already got — no special equipment, no draining anything first. Just open, pour, and go.
02
Drive Like Normal
No extra steps. No babysitting.
It does the work while you do what you’d be doing anyway. No schedule changes, no rituals required.
03
Feel the Difference
Over the next few hundred miles
Smoother idle, quieter run, better mileage — and it keeps working from there. Some notice it in days.
"You know the sound of your engine when it's happy. You know when it isn't. Give it the protection it deserves."
3 Steps.
That's genuinely all there is to it.
