I think that it can be important to note what the numbers of oil mean. 5-30 or 15-50. The first number is the weight of the oil when cold. the second number is the weight of the oil when HOT. Most oild get up to operating tempetures very quickly. It is important to have the same high temperture number as recomended. the lower number helps provide lubrication at start up. Especially in cold weather. There are some questions about wide ranging oil such as 5-50; they use additives to make a "thin" oil to stand up in heat (instead of thining out even more). These additives will wear out faster than your oil. Try and stay away from oils that have a "shift" that are more than 15-20 points. If you are a real oil nut use cheap oil and change it every 1500 miles or so. synthetic is great but still builds with crud like any other oil. ( I use mobile 1 syn. 15-50 and change every 3000) My understanding of it Todd T 84 & 76 Westy washington DC |
