type of oil

[Edbergh]

greetings all,

I have a 2011 jeep wrangler JK 3.8 lt , and about a month ago I changed oil and put in mineral oil 5w30 but recently I got an indiction
on the dashboard stating change oil???? should I go over to 10/30 synthetic ? I live In a very hot island enviroment 89 degrees farenheit
I went to look for some brands and found "Mobil 1 10w30 advanced full Synthetic" and CASTROL EDGE 10/30 API SN synthetic
on the market, any suggestions which one to use ? I have about 95.000 miles on it. thank you.

Did you reset the OLM (dashboard indicator) when you last changed the oil?

You can pretty much run whatever you want, if it's hot like that all the time 15w40.

Either of the 10w30's you mentioned would be a great choice.

I erased the codes on the OBDII but the indication comes on back when you are starting the engine, then afther a few seconds it goes away.

What oil is best to use . now, 10/30 or 10/40 or 15w40 for this type of weather? engine runs real smooth you don't even feel its running.

Run your oci and clear the soccer mom idiot light when it comes on, you don't need a OB2, just use your trip button and gas pedal. My last vehicle was a 6 cylinder JK, I prefer 5w30.

key on without starting. Gas pedal fully to the floor 3 times within 30 seconds of turning the key on. Shut off key and check. Works on many a Fiat/Chrysler.

I and many thousands more use the factory recommended grade in a lot hotter climate then "noord" which is 0W20.
