Lucas Oil10118 High Mileage Oil Stabilizer - 1 Quart

After putting Lucas Oil High Mileage Stabilizer through its paces in my aging 1999 Toyota Camry LE with over 189k miles, I'm ready to share my thoughts. This product claims to revitalize tired engines, and I was eager to see if it lived up to the hype. Here's my breakdown:Value for Money:Lucas Oil High Mileage Stabilizer isn't the cheapest oil additive out there. But, if it delivers on its promises, the cost is totally justifiable. Considering the potential to extend engine life and reduce costly repairs, it could be a smart investment in the long run.Build Quality:The stabilizer comes in a sturdy plastic bottle with a convenient pour spout. The product itself has a thick, viscous consistency, which suggests a robust formulation.Oil Quality:Lucas Oil High Mileage Stabilizer is a 100% petroleum-based product designed to blend with your existing engine oil. It's formulated to enhance the oil's lubricating properties, reduce friction, and protect against wear. I noticed a slight darkening of my oil after adding the stabilizer, which could indicate it's cleaning internal engine components.Leakage:One of the key claims of this product is to help reduce oil leaks. While I didn't have any major leaks to begin with, I did notice a slight reduction in minor seepage around the valve cover gasket after adding the stabilizer. It seems to have helped condition and swell the seals, just like it's supposed to.Lubrication:The most noticeable improvement was in engine smoothness. My Camry's engine seemed to run quieter and with less vibration after adding the stabilizer. This suggests improved lubrication and reduced friction. I also observed a slight improvement in throttle response, which could be attributed to better lubrication.Speed:While I didn't experience a dramatic increase in horsepower or top speed, the improved throttle response did make the car feel a bit more peppy. It's not going to turn your Camry into a race car, but the enhanced lubrication and smoother operation can make for a more enjoyable driving experience.Overall:Lucas Oil High Mileage Stabilizer appears to be a solid product that can offer noticeable benefits to high-mileage vehicles. It improved my Camry's engine smoothness, reduced minor leaks, and seemed to enhance lubrication. While the price is a bit higher than some other additives, the potential benefits make it worth considering for those looking to extend the life of their aging engines.Pros:* Noticeably smoother engine operation* Potential to reduce minor oil leaks* Enhances lubrication and reduces friction* May help extend engine lifeCons:* Relatively expensive compared to some other additives* Results may vary depending on the condition of the engineRating: 4.5 out of 5 starsRecommendation:I would recommend Lucas Oil High Mileage Stabilizer to anyone with a high-mileage vehicle looking to improve engine performance, reduce leaks, and potentially extend engine life. However, it's important to remember that this product is not a magic bullet. It's best used as part of a comprehensive maintenance plan that includes regular oil changes and other preventative measures.

Excellent product! Reduces engine noise, prevents leaks, and extends oil life. Perfect for high-mileage engines—smooth performance every time. Highly recommended!

The longevity sauce. This stuff is thick, gooey goodness that your engine will appreciate being added to the oil. I add an entire quart in my 95 305ci chevy every oil change and she is almost at 300k and my oil pressure will stay good and lubricant for way longer in my opinion. Helps with hard or dry starts, lifters tapping when starting engine it can help with that, low oil pressures?, some of this might fix it right up. No you dont have to use it forever if you decide to try it. No you dont need to use thicker oil like old heads say, just some of this with recommended oil. Ive seen many 18 wheeler shops keep this stuff in there trucks with over millions of miles on the engines. I recommend taking the sticker off, and microwaving the bottle for a while or getting it warm, a torch quickly works but the plastic liner doesnt like that, otherwise its gonna be a while before this stuff will come out the bottle its like the thickest syrup.

OEM-quality results! Slows leaks and boosts compression

As like every Lucas product that I have ever used it performs above my expectations. I use full synthetic oil and was noticing my oil pressure dropping as I would accumulate around 3,000 miles and I like to go 5,000 miles between changes. I started using the oil treatment and now the pressure stays up as it should. 279,000 miles on the engine and going strong.

Very expensive but premium product.

I have a 2016 Audi Q5 that consumes a lot of oil. I’ve used high mileage Lucus and it’s awesome.

This oil stabilizer works great I have a 2010 Silverado with 288000 miles on it lifters started chattering so I followed the directions on the bottle at first after the oil change I didn't hear any difference but after I got the engine up to temperature and drove it a bit I parked it and it sat for the rest of the week and the following weekend I started it back up and all of the chattering was gone I'll be using this Lucas product for the remainder of the life of this truck and also in my 2017 great product
