    I have seen multiple tests on synthetic oil (supposed to last 2 to three times longer) Any thoughts on this in mowing equipment? Have tried it in my 00 F-350 (amsoil 15w-40 diesel oil) ran it for 15000 miles no problem.

    Synthetic oil is YOUR choice - but DEFINATELY not necessary for long engine life. :usflag:

    Oil in a mower will get to dirty long before the oil itself breaks down. I use synthetics but not for the extended drain intervals.

    Here is what I use....

    As stated, regular changes of any oil will extend the life of any engine. Amsoil has a great multiple filter system that is used on vehicles and if I am not mistaken Dixie Choppers. The only way to get extended change intervals is to run in a clean environment or use the multiple filter setup.

    Heat is the second culprit for breakdown of oil. We have plenty of that in small engines. Synthetic does stand up to heat better than petro oil. It is also more flowable in cold weather. Take a quart of petrol oil and a quart of synthetic (same weights) and stick it in your freezer overnight. Open and pour them out at the same time in the morning.

    Synthetic is more expensive without a doubt. I use it and have had great luck but I know guys who do regular changes of cheap dino oil and the have many hours and miles on their stuff. Your call.
