User Reviews

Buyers often report that their vehicles run smoother after using Lucas Oil Deep Clean Fuel System Cleaner.

People who go into using this product thinking that it’s a magical elixir, that’s meant to fix a host of engine problems, tend to be the ones who are disappointed.

Lucas Heavy Duty Oil Stabilizer

Lucas heavy duty oil stabilizer is known for extending the longevity of oil, by up to 50%. It can be used with just about every gasoline vehicle, including personal watercraft and off-road vehicles. Part of what it does is slow the rate of oil consumption down within an engine, making it beneficial to be used in vehicles that burn oil too quickly. Being as thick as it is, Lucas Heavy Duty Oil Stabilizer naturally increases oil pressure, and has similar effects to a normal thickly graded oil. It also helps to prevent dry-starts from happening.

Motors experiencing a lot of friction, which can quickly wear an engine down, can benefit greatly from this Lucas Heavy Duty Oil Stabilizer. When oils are more efficiently lubricated, they burn at a slower rate due in part to lower temperatures, which is exactly what this oil stabilizer accomplishes.

User Reviews

Like most Lucas Oil fuel additives, online users tend to reflect on their experience positively, after single or multiple uses of Lucas Heavy Duty Oil Stabilizer. The occasional critical review seemed to highlight the products thickness, saying that it could be problematic for certain modern engines. Others, who believe the product contains no helpful additives, simply resort to thicker grade oil as an alternative. Lucas Heavy Duty Oil Stabilizer is petroleum-based, making it safe to mix with most engine lubricants.

Lucas High Mileage Fuel Treatment

It also helps to extract harmful valve deposits that could be limiting productive air flow within engines.

Unlike many fuel additives, Lucas High Mileage Fuel Treatment won’t destroy oxygen sensors. It’s also compatible with many modern vehicles, including port-injected motors. It has been shown to work best with high-mileage vehicles. When used, entire bottles are typically emptied in a tank before each new fill-up, an important order which ensures that each use is properly mixed.

User Reviews

Although it exists somewhat on the fringes of the Lucas Oil fuel additive market, Lucas High Mileage Fuel Treatment also has a fair share of dedicated users. Similar to the review sections of other fuel additive products, disappointment seems to be the norm when people expect too much out of these mixtures. They’re not check engine light saviors, but this product in particular keeps fuel systems well lubricated, and extends the life of oil. With many fuel additives, the positive effects are never exactly felt, but they do play their part in helping to prevent the premature overhauling of a young engine that should be in tip-top shape.
