This one is no exception. Quality fuel system cleaner for a very reasonable price. Used on several cars in the past and recently used on a 2018 rav4 with 40k. Didnt notice a big difference but didnt expect it either on a car with lower miles. Plan on doing this once a year as preventative maint.

5.0 out of 5 stars Nice Product

Must have to clean and boost Fuel system. Dropped in on empty tank and then filled up the gas. The change could be felt after few miles of driving. The engine noise has greatly reduced and the pickup also increased. Before using this on my Camry hybrid the MPG needle would show 30 MPG and now its shows between 35 and 40 MPG on the same stretch of road that I drive daily. The product has good reviews on Oil Forums and that prompted me to try it. Though the price is on the higher side, i recommend to anyone who want to have their vehicles for longer periods.

5.0 out of 5 stars Perfect for direct injection vehicles

I added this product to 15 gallons of Shell V-Power 93 octane in my Audi. My car normally runs very well on V-Power alone but it REALLY came to life with the Lubegard additive in the tank. I've used strait octane boosters in the past and the car performed in a similar manner with the Lubegard. This additive is one of the few with an upper cylinder lubricant which provides lubrication to several parts of the direct injection system as well as the upper cylinder walls. I plan on using this additive twice a year.

I have not noticed any difference in my course performance as it has been three days since I poured it into my gas tank

3.0 out of 5 stars Good Product, Terrible UNSAFE Shipping package

S.G. · June 23, 2022

I like the product but they need to do a better job with the packaging. This is my second time ordering three of them and they again arrived all dented up. They did not include any padding in the box so all three of them must have been banging into each other in the oversized box during shipping. This is a combustible liquid and they need to do a better job of packaging these for shipping. What if one them started leaking and then the metal cans banging into each other caused a spark? Additionally, there was nothing on the outside of the box to indicate that the items inside were combustible!!!

city driving builds up carbon try this once a month with full tank of gas ( solves many check engine light problems}

5.0 out of 5 stars Highly recommended

J.H. · January 2, 2017

Have used many fuel cleaners, but this one seems to have had the greatest impact. My fuel economy had declined to an average of 17.5MPG or so. This brought it up progressively over the course of a tank to 21.5MPG. I used another additive in the engine. There could be a combined effect, but it seems to me that Lubeguard is doing the heavy lifting on this one. Let's see how long the gains will be sustained. But it seems to be a really good value and quite effective.

5.0 out of 5 stars Very Good High Quality

I have direct injection and am concerned about carbon build up. This is one of the few products made for DI automotive, and I trust the company because I have had very good success with some of their other products.Long story short...it ran like a raped ape with product in the tank, not to mention the normal soot in my tail pipes is pretty much so gone. I had cleaned them before the dosage and then monitored the soot afterwards. I'm happy with this product.

Little difference

Nd felt slight difference in car acceleration.. ... May be regular usage as suggested every 3k miles make a difference but for now noticed only slight improvement.
