    Hi guys, I hope you all are having a good morning, just out of curiosity my Jeep cherokee repair manual (XJ) said I can run 5w-30 if it gets especially cold out, however it says I can also run 10w-30 but that it shouldn’t be run below 0 degrees F, but under my hood they wrote on it saying they used 10w-30, next time I change my oil should I put in 5w-30 because it’s winter time or put 10w-30 and just use the same stuff they did?

    I would run 5W30 for easier starts and less cold start wear as stated in the manual.

    Another way of looking at it would be to run a heavier weight oil as a '95 xj probably has a lot of miles on it. Either way changing it at the proper intervals is critical. Dirt and metal chips don't lubricate very well.

    Is your vehicle in Maine or Florida? garage kept or left out? I have run 30 weight in the jeep I leave in the heated garage. Had no problems in the winter.
