UT0811A -- Does it take straight gasoline or a blend of gas and oil?

The exact mix ratio for Cub Cadet trimmers varies, depending upon the exact model. Cub Cadet's ST 228 2-cycle trimmer model uses a mix of 2.6 fluid ounces of 2-cycle oil blended with 1 gallon of unleaded gasoline or a 50-to-1 ratio. This equates to 20 milliliters of 2-cycle oil to 1 liter of gas. The Cub Cadet BC 210, on the other hand, requires a mix ratio of 40 to 1, or 3.2 fluid ounces of 2-cycle engine oil to 1 gallon of unleaded gasoline

While the two cycle oil has it on the back of the bottle but with my 1998 I would pure a bottle in it or depin on how much gas you got I like my gas kind of a blue tint

According to the manual, "use unleaded regular gasoline with a
min. octane value of 91." You need to mix oil into the gasoline at a rate of 50:1 or 2.5 fl ounces of oil to one gallon of gas. If your saw has little power or is very hard to start, it may have been run with straight gas in which case the piston ring or cylinder or both may be damaged enough to warrant replacement.

If you use ethanol blended gasoline this is normal. ethanol blended fuel doesn't burn as well as regular unleaded

if you use unleaded non-blended fuel
A good thorough tune up should remedy this.

change spark plugs and wires
air filter
fuel filter
engine and transmission oil and filters should do the trick

Hi,

Gas to oil is 50 to 1 or about 2.8 oz. of two stroke oil to 1 gallon of prem. gasoline...

40:1 is a safe bet for just about all chain saws.

All four stroke motors use straight gasoline or benzin. Only 2-stroke engines use a gas (benzin) + oil mix. Even some later model 2-stroke engines run straight gasoline and have a pump that mixes the oil with the gasoline. Most 2-strokes built after the mid-70's have the pump. You can easily by examination of the throttle cable. If it's equipped with a pump, the throttle cable will split from one cable on down to two cables where it enters the engine. Read your owner's manual.

If it has an oil stick, it is sraight gas. No oil stick to check oil then, gas/oil mix needed.

Its fine to change your oil with synthetic, Just be sure that you use synthetic from now on... I don't think its advisable to switch back to regular oil after using synthetic.
