Good result

I put this in my 2014 diesel car with 96,000 miles, without fresh oil. Oil has about 4000 miles to its name, and it honestly made a difference. I used to be able to hear the diesel clatter echo off walls and parked cars etc, but now it’s nearly non existent. I do believe it runs smoother too, but that may be a placebo. I’ve only just done it so I can’t comment on longevity, but results are immediately noticeable. After putting it in, I’d say I noticed the difference within 10 miles.I also put some in my wife’s 2012 mini because it sounded like a diesel even though it’s petrol, and it has quietened it down quite a bit. It’s not miracle juice, but does help with noise, so I imagine it is doing wonders for the engine.I will see if it helps MPG when I do my 200 mile trip to work next week and update this post if there’s anything to report.

Used in three vehicles with varying results

Wynn's Formula Gold Engine Oil Treatment.I first tried this product a few weeks ago on an engine that had just clocked 100,000 miles. I did NOT change the engine oil before adding it, as changing the oil alone can make quite a difference to engine performance, and I wanted to see if I could feel any difference in the engine by using the product with the existing oil.The first engine I tried it on was getting a bit noisy, and starting to feel quite tired. We service our vehicles regularly, and always use the best Castrol oils, so I didn't really expect to see too much of a difference, but I was really surprised at the results. There was quite a bit more punch to the engine after adding it. The change in performance still seems to be there several weeks later.After being impressed with the product with the first trial, about a week ago, I tried it on another car we have that has also just crossed 100,000 miles, and again, the effect was very noticeable. The engine seems much quieter and smoother.Finally, yesterday, I added it to a third car that has just 75,000 miles on the clock to gauge the effect. The engine in this car was still running quite well, and this time the effect wasn't nearly as noticeable. The improvement was slight.So my initial impressions of this product are:A) Much to my surprise, it does actually workB) It seems to work better in some engines than others, with higher mileage cars perhaps benefitting more.C) It seems like quite a good deal if you want to add a bit of perk to a jaded engine.Just to repeat, with all three cars, we did NOT change the oil first.

It's a good product

This oil additives is probably the best thing I've ever tried regarding car products. it does do what it says it's going to do. I've put this in my car and it does increase power. and it does dicrease smoke. So it does what it says.

Good additive

A lifelong reliable brand that assists the engines protection for new or older ongoing life. Make certain that the oil level is below the Max before adding to ensure that there isn’t an overfill
