Ottimo! Ma attenzione all'MMT
Probabilmente uno dei migliori octane booster che si possono trovare tra quelli commerciali e in dosi per utilizzo non professionale. Attenzione che essendo un booster a base di MMT, pur essendo un ottimo innalzatore del numero di ottano, può lasciare depositi di ossido di manganese, sporcando candele, valvole, catalizzatore e sonda lambda. Gli additivi detergenti aiutano tuttavia a pulire gli iniettori, e l'effetto antidetonazione in proporzione alla quantità di prodotto è sensibilmente superiore a molti altri prodotti. E' quindi indicato all'utilizzo su autovetture più a indirizzo sportivo che utilitarie modificate (quindi senza catalizzatore e utilizzate saltuariamente) e magari da usare solo in occasioni specifiche ove si prevede di tirare l'auto e si vuole ridurre al minimo il rischio di detonazione anticipata, oppure come soluzione di emergenza qualora ci si dovesse trovare in luoghi sprovvisti di distributore con 100 ottani. Ne sconsiglierei l'utilizzo continuativo.

Works as described 100%
To start, I’m normally not one for leaving reviews, but I honestly felt this product deserved it. So when I researched this product, it sounded great, but I was still sceptical. Now that I have used it in my 2015 Ram 1500, I can honestly say, that it is a solid product & I can definitely feel the HP difference, the truck pulls way harder & is very responsive. I do recommend this for sure.

Honest Review from a Porsche Owner, Can’t Confirm Performance Gains, But Here’s Why I Still Use It
Full Disclosure Up Front: I’m going to be straight with you. I cannot honestly tell you this product made my car faster or smoother. I run it in a 550 hp Porsche that already has way too much power for me, so any 3-point octane bump is going to be lost in the noise of an engine that’s already overbuilt for the job. If you’re looking for a butt-dyno review with seat-of-the-pants impressions, scroll on, I don’t have one for you. What I can tell you is why I keep buying it anyway. Why I Use It Despite Not “Feeling” a Difference • The Garage Queen Problem: My Porsche isn’t a daily driver. It sits more than it runs, especially through Upstate NY winters where road salt is a death sentence for anything with an aluminum undercarriage. Fuel sitting in a tank for weeks at a time degrades, and premium pump gas in this region is sometimes… optimistic about what “premium” means. • Insurance, Not Enhancement: I treat this the same way I treat dielectric grease on outdoor electrical connections at work, I can’t prove it prevented a problem, but the cost of using it is trivial compared to the cost of not using it if something goes wrong. A bottle is cheap. A high-performance engine repair is not. • The Royal Purple Track Record: I’ve used their synthetic lubricants in professional and personal contexts for years and they don’t tend to sell garbage. That brand trust is doing some heavy lifting in my 5-star rating, and I’ll own that. • Pour Quality: Bottle design is good, tight cap, no drips, easy to funnel. Sounds minor until you’ve spilled additive on a clear-coated fender. What I’d Tell a Coworker If you have a high-performance vehicle that sits a lot, or you’re stuck with questionable pump gas, this is reasonable cheap insurance. If you’re driving a turbo-four daily and chasing measurable gains, you’ll probably get more honest feedback from someone whose car isn’t already producing supercar power. I’m rating 5 stars on brand reputation and product quality (packaging, formulation claims, pour experience), not on a performance test I’m not equipped to give you. The Wife Approval Factor is neutral, which for a $20 garage chemical is honestly a win. Verdict: Probably best for owners of low-mileage performance vehicles who want preventive fuel quality insurance, not drivers expecting a measurable kick in the pants. Skeptics looking for proof-of-performance should read a review from someone with a more sensitive testbed.
