A oil change was done to my 02 Saturn, about 3 weeks ago by a gas station mechanic. Tonite driving home from work (late nite with little traffic, maybe a 15 minute ride) the oil light came on. About a mile from my house the car became very sluggish. It did not stall out and the oil light would only come on when I would stop for a light. I did make it home OK but the last half mile the car felt like it did not want to go over 30 miles an hour. I know the car probably needs a thermostat. My questions are is it possible the mechanic did not put enough oil in it or is it related to the thermostat or something else entirely. Is it safe to drive to a gas station to have it looked at? Any help would be appreciated, I need my car for work. THANKS!!!

i guess before you take it back check the oil if it shows on the dipstick thats good see if it still looks like oil or its contaminated this way you know if it is low on oil and if there is something terribly wrong... it does not sound good but you never know... the best thing would be to tow it since you dont want to create more problems
