Yeah, I wouldn’t use any fuel additives either I forgot, Techron is already in some Top Tier fuels. Is it in Costco?

If it’s economically feasible for you, you can try it. I’m sure it will not hurt your fuel system. There is not yet enough data to form an opinion yet. Although, this is not like an oil additive where you are taking a gamble.

"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." "The additive is built on a new chemistry that contains both detergents and solvents. Since the formula is proprietary we can not go into a ton of detail, but can tell you in ASTM D6201 testing the additive has proven a 98% improvement over Top Tier base fuel for Intake Valve Deposits, the industry standard for GDI testing in GM LHU Injectors proved a 100% clean up in 1 tank full, and that the formula gets an A rating in corrosion protection." Anyone that's interested in deep diving the discussion can view it here: https://bobistheoilguy.com/forums/th...leaner.404114/ Sounds like they found a new way to go about removing deposits. Makes me wonder if it's a similar additive to what they use in their R&P line of Oil's.

Thank you for your opinion. After all, it’s just an opinion which may or may not be informed. I will not ask, but I’m sure it’s backed up by diligent research and firsthand experience.
Reminds me of my 86 year-old uncle who 10 years ago said that mobile phones are only used by pimps and hookers. Now he sleeps with his mobile phone under his pillow

I think there is a reason car bakers are starting to add port injection to DI engines. GM is doing it now for their V8s, in part to reduce carbon on the backs of the valves and in part because port injection is better than DI during extremely low loads like engine idle. |

![]() For the people here that have Gen 3 B58's, we have DI and PI combined, so there's potential for some benefit beyond simple fuel system cleaning later on when mileage starts racking up. That all said though, intake deposits haven't really been something I've heard too often since the N54/55 days. I'm not sure what exactly BMW changed that made this basically a non-issue but I'm grateful to not be planning out walnut blasting in the future anymore.

I share your opinion. I also believe this is more of a general approach by Valvoline. Their 100% claim maybe (should be?) caveated by the type of engine. It’s certainly a very bold claim. And since it’s coming from a major player with a good track record in the industry, it’s worth not to dismiss it off-hand. A lot of people are jaded and confused by all the various “snake oils”… so looking out for future factual credible data and objective evaluations.

imagine if Christopher Columbus, Neil Armstrong, J. Oppenheimer, or even Albert Einstein said "what could go wrong?" before they tried anything... like my former Mercedes salesman of 27 years always said to me: "no guts, no glory!" (although he really meant "no guts to buy a new Mercedes that you can barely afford, no glory on my sales chart for this month, no commission for me?") try the additive and report back! |

Having said this, I am going to try this R&P fuel cleaner. The problem is that my car with 118k miles is running as smooth as when I bought it at 28k. So not sure what to look for as far as improvements. My mileage is still the same as when I got it, not burning any oil, the slightly jumpy idle smoothed out after three R&P oil changes throughout 7k miles, the injectors still sound like diesel, and I am not going to tear down my valve cover to check for deposits ![]()

If I could blow out my engine on the highway once a month with sustained high RPM driving, I may consider not using any.

However buying a new product just because it "claims" to "restore and protect" is preposterous. There is quite a few tried and tested products that works as they should. |

I am not the type who made up his mind 30 years ago and never changes it, even as technology advances daily...often beyond the comprehension level of the individual who off-hand dismisses anything new and unordinary. Would love to hear your recommendations of your "tried and tested" products you swear by. I do not have a PhD in Tribology...so you need to convince me with facts that your products are not just "marketing". And please, do not be one of those people who recommends a product just because their old man used it for 60 years and swears by it....or just because its ingredients were used in the Space Shuttle.
