I have an oil analyzer and use it to determine when I need to change my oils. I hate throwing away good oil. Those damned oil companies are making BILLIONS of dollars every quarter (3 months)!! Using Mobil 1, I have only been able to get 10,000 miles on my VW Jetta diesel engine before the analyzer told me I needed to change it. With Amsoil 15W-40 Synthetic Blend I have gotten 20,000 miles and the analyzer told me it was still good! Of course, I changed the oil filter every 5,000 miles, using WIX, and add 1 quart of new oil at that time. I don't know how many miles I could have gotten on the Amsoil but I just could not get my head around 20,000 miles on an oil change! I have used Amsoil fully synthetic 2-cycle oil in my chain saws for over 30 years at 100:1 ratio, with excellent results - no smoke and engines lasts "forever!" The Stihl 041 Farm Boss I bought used 27 years ago is still going strong. The Stihl 011 I bought new 25 years ago runs like it did the day I bought it. I am not a dealer for Amsoil. I don't even like the company - they are too arrogant. If I could find a better product, I would buy it, but I can't. I am sharing my experience with you FYI.
