SOURCE: Can putting 10w30 synthetic oil instead of 5w30

5w 30 is much thinner than 10w 30. Most newer vehicles require 5w30

I personally like synthetic oils because the viscocity adjusts with the temperature in all climates and weather. No need to change every season

If you put anything other then Motor oil in the car then do not drive it and change the oil were it sits ASAP.If Motor oil was put in the car, change you oil with the correct oil.Ask for help at your local auto parts store for the correct oil, But i would advise to let someone else do it.

You need to determine where the oil is being lost. Open the hood and look for traces of oil. Place a clean piece of cardboard under the car and idle the engine - at the rate you are losing oil, you should see where the oil is dripping onto the cardboard within a few minutes, then work upward from there. Possibilities: Crankshaft seal (passenger side of engine), valve cover gasket (top of engine), main seal (driver side of engine). Any of these can go bad, far many reasons.

verify good spark plugs and correct ignition timing. make sure the engine is getting to correct temp (195f) Has the mileage always been this bad? be sure the cam timing is correct.
