Re: 1998 Grand 8 cyl 5.9
We too have a '98 ZJ 5.9 Limited. Gas prices were higher when we bought it
than they are now. It is a 'weekend and trip' vehicle for us, not a daily driver. Both of our daily beaters are Hondas. It seems that middle grade gas might be OK but since our use of the beast is limited we don't mind paying for premium. FWIW I was told that the computer can be programmed for lower octane gas. If you experiment with the different grades of gas I would appreciate hearing your experiences. Since I'm asking for your opinion, I would like to know about your shock absorbers. I asked here about a month ago about what to put on my beast. I went with the Edelbrock Performer IAS's. I am happy with them but only have the originals to compare with. What shocks are on your ZJ? Do you like them? Why / Why not?

The knock sensor will do exactly the same thing, retard the spark with exactly the same results, less performance and less gas mileage. It's probably cheaper to run premium. Some engines have low compression kits available for them, I'm not sure the 5.9 is one of them. They may consist of low compression pistons or different cylinder heads which are VERY costly and it would take years to make up the cost in savings on gas price or there may be thicker head gaskets available, still costly because of the labor involved but much less than the other means of lowering compression... Again, it's cheaper to run premium and make sure your *next* vehicle runs on regular. As for shocks, I have a lift mounted on the back of my Jeep to carry a mobility scooter so I needed to get air adjustable rear shocks, that very much limited my choice, I just got what was cheap. |

Re: 1998 Grand 8 cyl 5.9
My dad has one of those 'go-karts', and it is difficult for my mom and
sister to disassemble it when they go on a trip. What lift do you have? Wish you'd gotten something else? Thoughts/comments?
