Leaf Blowers

I recently bought a 150BT backpack leaf blower and also purchased through Lowes an additional 3 years warranty. When I filled out the registration on line, it asked if I bought 6 contains of oil with it. Does this also extend my warranty? Is it over and above the warranty with lowes? I sent my receipt as a "JPG" during registration to prove I bought the oil, plus the new 150BR. Thanks
