It's time to change my oil, and last time I had it changed I used synthetic. I thought I remember hearing somewhere that if you change to synthetic you have to keep using synthetic. It might me something I misread, but I was just wondering?

Nope. Use whatever you want. 5w-20 is best for FL.

 

i think that's an old "wives-tale".

Over the years, I have put synthetic in cars, trucks, motorcycles and even a John Lawn and Garden tractor. I switched them all back to dino and there have been no problems. Also, many people insist you have to use the same brand all the time. Another wives tale. You can switch to any oil that meets the requirements. The engine doesn't know or care what brand you use.
