10W30 vs 10W40 in a 2002 TJ
Is their a serious downside to using 10W40 as opposed to 10W30 in a
2002 TJ as I appear to have a lot more choice of oils at this weight
than the 10W30 in full synthetics. I was reluctant to go down to the
0W30 & 5W30 unless anyone has an opinion to the contrary as I do not
need that amount of cold weather starting capability.
Cheers
Nick

The first number doesn't matter that much, but the second does. I've
been running 5W30 for quite a while and it works fine. Now if your in
a very hot climate then 40W will work well. When all else fails consult
the service manual or call a local Jeep dealer.

I run 10w30 90% of the time in my TJ. But when I make trips out to
the colorado river where the temps hit 120+ on he AZ/CA border I use
10w40. I have heard some horror stories in other groups regarding
10w40 with too many polmers being added which makes the oil break down
quicker. I don't buy into it. Just change your oil at regular
intervals and you should be fine even if you do run 10w40.
In fact I have an over worked 150k miles dodge neon that I beat up on
a 90 mile commute every day, and run 10w40 on the smoking hot days of
socal desert summer. Never had any issues with this engine. Maybe
I'm just lucky.
