Well, I bought this because a mechanic put synthetic oil in my friend's 99 Buick LeSabre that had never had synthetic oil. The engine had 175,000 miles on it and never has seen synthetic oil. After running the synthetic oil for about 5,500 miles, a few drops were visible here and there. So, I figured that changing the oil back to organic oil and putting some of this in would fix the problem. I bought this in the winter, but I waited until we got hot weather to use this since I don't know how this will work during -0 degree F starts since it looks very thick.

I've been using this for my lawn and I have to say it works wonders. I purchased a house with a shared front lawn which looked quite frail and green-yellowish colored. I applied this product and about a month later my neighbor asked if I was putting steroids into my lawn. My half of the lawn looked absolutely beautiful compared to his side of the lawn. The best thing about this product is that it's dummy proof. You WILL NOT burn your grass if you put more than the recommended amount since it's organic. I recently tried buying this product again at Home Depot and they were not in stock. I then tried Scott's Iron and Fertilizer mix and I ended up burning my grass. I followed the exact instructions but my drop spreader continues to drop granules even though I closed off the switch when I have to turn. This created small patches of more product at those locations where I stopped which in turn burned my grass. A lot of fertilizers are synthetic so it's very easy to burn your grass if you make a mistake or use too much at once. Milorganite is very safe, will not burn your grass since it's organic and will make your grass look green and healthy. I highly recommend this product but buy it from your local hardware store or Home Center. I bought a 36 lb bag for $12 at Home Depot in New York.
