From a post on bobistheoilguy, a relayed email from the manufacturer's product support team:
"There are no PEA (polyetherimide) cleaners. We use a brand-new proprietary fuel additive technology developed and proven to remove deposits better than PEA, while also helping keep the system cleaner longer. Give it a try, there is a 100% satisfaction guarantee."
"The new Valvoline Restore and Protect™ Fuel System Cleaner is a high-performance deposit control formulation engineered to deliver up to 100% removal of fuel system deposits in Gasoline Direct Injection (GDI), Carbureted, and Port Fuel Injection (PFI) engines within a single tank of treatment, as validated through real world and ASTM laboratory testing.
This formulation incorporates a next-generation proprietary detergent chemistry specifically developed to withstand the elevated pressures, temperatures, and injector tip coking environments characteristic of modern GDI combustion systems. Performance validation includes ASTM-based deposit control and cleanliness evaluations demonstrating complete removal of injector and intake valve deposits under standardized test conditions as well as in real world testing. The product also meets Top Tier™ detergent performance standards, ensuring compatibility with advanced deposit control requirements.
Functional benefits include:
Restoration of optimal injector spray pattern and fuel atomization efficiency
Measurable improvements in combustion stability and fuel economy
Reduction in hydrocarbon and particulate emissions
Lowered boundary friction within upper cylinder regions
A-rated corrosion protection performance
Mitigation of engine wear through enhanced surface protection
Additionally, the formulation contains an advanced friction modifier package designed to further reduce parasitic losses and wear rates, contributing to additional gains in fuel economy and long-term component durability.
For optimal continuous deposit control and system cleanliness, application is recommended in conjunction with scheduled oil service intervals or at 3,000–5,000 mile treatment cycles."
Evidently, this product incorporates similar technology as Valvoline Restore and Protect Engine oil, which has become something of a gold standard engine oil the past few years.
