I feel like most reviews complaining about this machine could have been avoided if people READ THE MANUAL. This compactor is great value for the money! Please read the manual, as it specifies which oil to use depending on your ambient temperature and how much oil to put. I had to use SAE 30, as I am in Arizona with ambiet air over 40°F and I am guessing most people should actually use that. Mine arrived covered in oil, so I made sure to add oil to the vibrator assembly and cleaned up the spillage. I had no problem starting it up with the engine oil filled to about 3/4 of the gauge stick and gas filled to the bottom of the gas filter. No leakage occured just a bit of smoking right at the beginning that lasted less than a minute, which is normal on engine startup. Overall, easy to use, sturdy, relatively compact machine that does the job if used correctly. P.S. it comes without a paver pad so I am using a small rug that my wife wanted to throw away :-)
