There is oil on the gauge tip....but when I start the lawn mower and put it in gear greyish smoke pours out of the left front....The last time I used it I checked the oil, again...it was about 1/4 in on tip. I can not find the manual, the machine was purchased last year. I have no clue what type of oil it uses I did not mix oil and gas. so what Kind of Oil ? How Much? and how far up on the dip stick is it suppose to be. ................................
