For vehicles under 50,000 miles. Cut engine wear about 20% and add 100,000+ miles of life - proven on your own engine with independent lab analysis, and completely warranty-safe.
Your engine does the most damage in its first years — every cold start, every hard acceleration. ProTecta's New-Car Protection Program bonds a protective layer to metal surfaces and keeps it in place, so a newer engine stays factory-tight for 100,000+ miles.
Independently measured by WearCheck lab analysis — not a marketing claim.
Compatible with every motor oil; safe for vehicles under manufacturer warranty.
Treatment protects metal; fuel system treatment keeps injectors 97% clean in one tankful.
Add it at your next oil change and drive normally — measurable wear reduction, no routine change.
One bottle of Engine Treatment in the oil, one Fuel System Treatment in the tank.
Extreme-pressure additives form a protective layer that lasts the entire oil-change interval.
Your program includes WearCheck oil analysis kits — mail a sample and see the exact wear reduction in your own engine.
Both include WearCheck oil analysis and free shipping. The Full-Year Program is a full year of protection at the lowest cost per treatment.
Prefer to start small? Grab the single Synthetic Engine Treatment for $19.99.
