Vehicle is a 1994 Jeep Wrngler 4.0L 242ci. I6.
A little history; The previous owner put approx. 75-80K on the ticker when I bought it 3-4 years ago. Since I have owned it, I have put maybe 10-14K. Most of those 10-14K miles were in the first year I bought it because it was driven on a daily basis. Over the past 3 years, I have put maybe 3K on it. The jeep is just a trail vehicle and does not get out much. I have been running regular ol' 10w30 (not that says much - I have only changed the oil twice since I have owned it) I know, I know... I do start it up (let it run for 15-20 minutes) every couple of weeks when I am not driving it though.
The valve springs and lifters have some varnish build up on them and the whole top end is dirty! I was thinking of do the Auto RX gig but wonder how it will work with the limited milage I put on the jeep. Since I only drive it maybe 1K a year, how can I do a good cleaning and rinse? It's litterally only driven to and from the trails. It's not really practical to get out and drive around town to get a good cleaning cycle in. Heck, there are some years where I only put 200-400 mile on it.
Or would I just be better doing the Delo 15w-40 since it has more detergents in it. I really don't think the thicker oil will hurt the inline 6 and the fact that it is only driven in the summer.
Any help would be appreciated!
