I heard a lot of good things about Lucas Oil products, so I ordered this fuel treatment. It does what it promises, but I didn’t notice a huge difference in my vehicle's performance. Maybe I expected too much? It’s okay, but I might try something else next time.

Great for keeping my engine smooth
I bought this Lucas Oil Upper Cylinder Lubricant to treat my fuel and I can really tell the difference in my engine's performance. It’s a 1-gallon pack and I’ve been using it for a few weeks now. My car runs smoother, and I feel like I’m getting better gas mileage too! Definitely worth a try if you care about your engine.

Decent product but packaging could improve
I got the 4-pack of this lubricant for my truck, and while it does help with engine smoothness, the packaging was a bit dented when it arrived. It still works fine, but I was expecting better packaging. Just a minor hiccup though, product quality seems solid so far!

Arrived damaged, but product works
I was really looking forward to using this upper cylinder lubricant, but unfortunately, one of the jugs arrived cracked. I managed to use the rest and I do think it’s helping my engine run better. Just wish it had arrived in better shape!
