What type and grade of oil is required. I have lost my manual and do not remember what oil is required. Troy model TB4SC gas blower.

Hi lenore thorpe

You will fill your blower with low test/ grade of gasoline..no need for the high test.
You also said that it is 4 cycle, so DO NOT MIX OIL WITH THE GASOLINE...
Please rate me

I always suggest using a full synthetic 2 stroke oil for these machines. It provides superior lubrication qualities and burns cleaner than conventional oil. The fuel/oil mix ratio is 40:1. That is 3.2 ounces of oil mixed in 1 US gallon of gas. Half that to mix up a 1/2 gallon. You can find this info and more in your manual. The fuel info is located on page 10.

Your user manual would tell you exactly what to use, if you have it. If you need a manual you can download a free one here, but you will need the serial number of the machine in addition to the model number.

simplest answer is that its overfull of oil, make sure its sitting upright when you check the dipstick. remember to screw the stick in then remove it to check the level. Be sure to use only SAE 30 non detergent oil so it does not foam. The secont possibility is thatyou have more then 50 hours running time on it and the rings are worn out.If thats the case, bite the bullet and buy a 2 cycle machine like either ECHO or RED MAX or Husqvarna. Try to stay away from box store machines as they mostly all have a 50 hour life expectency. Write back if I can help more?? JIm

If it is a 4-cycle, it does not come with oil in it. If it is a 2-cycle, you must mix oil into the gas according to the owners manual...Good luck

If you ran plain gas in a 2-cycle engine and it seized... you need to buy a new one. 2-cycle engines depend on oil in the gas for lubrication. If you run straight gas, there is no lubrication, the engines overheats and seizes. The end, unfortunately.
