I've read the many posts here concerning the 3.2 engine's perchant for
"ticking". I have a '96 Trooper that I bought used about a year ago.
124k on the clock now. Previous maint patterns unknown, but my guess
is it was a bit neglected. It's always ticked, mostly when cold until
a couple of miles into it, then the tick goes away for the most part.
It does hit a "sweet spot" where it rarely ticks when cold and then
drives normally. At worse, it ticks a lot, kinda telling me to change
the oil.
I've been running Mobil 1 the last half dozen changes, using their
10w30 High Mileage formula the last two. About a week ago the ticking
went to "full time", which it has never done. It was nearing its oil
change time so I decided to toss in 0w30 and see if that would really
clean it out. I did the change but no go, I still have the tick full
time... maybe some real goo was dislodged and is really blocking the
oil ports, or...?
Anyways, has anyone used Auto-RX and how well did it work? From what
I've read on the 'net, it seems like folks have had good success with
it really cleaning their engines and all the nooks and crannies. If
the full time tick doesn't go away, I'm tempted to give it a try.
Thanks for any input.
