I agree with your answer! On syn lubes having less sulfur.94beachxj:
Nothing went wrong. All GL-5 oils are designed to resist high heat but all
do not do it the same way. Those with high sulfur content end up being
dangerous for yellow metal. Some people have bad experiences with those,
and Tim's post #2 in this thread is trying to help Jeepers avoid that problem.
The Amsoil GL-5 you are fortunate to have chosen is Synthetic, safe for
yellow metals, and GL-4 compatible.
But, if you still think any GL-5 is just fine, why not put a high sulfur one in
your favorite Jeep's AX-15 and check back here in a year or so ?
I have had some time off this week I made a few phone calls and you are correct about using syn lubes. I guess we should look in a tad further on the Chrysler so called "recall" on this situation. I have not found any legit one so far, but thanks for your post.
btw,,,,,,,I called Chrysler Jeep on the so called "service notice" on my jeep and they had 0 on it as far as changes.:wave:
Bottom line is go with what the manufacture states in the owners manuel.
