Oops. I managed to grab a case of 5-30w instead of my normal 10-40w. How big a difference does this make? Its a 98 TJ. Mostly used for wheeling and some comuting, especially in the winter. Do I take it back and exchange it, or just keep it and burn it? Opinions?
Oil, big difference?

10w40 is too heavy for winters up here ... 5w30 is the norm.
depends on where you live; You'd need to have a 30 weight here in Maine in the winter. Look at your owners manual, it will show you the temp ranges for the viscosity oil you should use.
Up where?
Guess I should have said I was in the Pacific North Wet.
Owners manual? Whats that?

5W-30 is fine Jen. 10W-40 is the wrong stuff, 40 weight (which is what
10W-40 is when it is warmed up) is just too heavy of a viscosity. I usually run 10W-30.

Winter's coming so you are probably fine, Make sure you use it up or trade it off before springtime.
It is synthetic isn't it? If not take it back.
Heh, where I live the expected winter temperature is -20º to +65º, which can happen in the same twenty-four hour period. I guess I am screwed.

All the more reason to use synthetic.
The little book that recommends 5w30 or 10w30 (preferred) for a TJ, not
10w40.

Move to Cutbank Montana. Wider 24 hour temperature range [a world record last time I cared to check], lotsa natural gas, and bugs big enough to give you a tow if you get stuck. Oh, and nothing but miles and miles for miles and miles.
