I have a couple of questions: I have an 06 Jeep Wrangler Sport I bought last year as certified used and I love it and want to keep her in good condition. I feel like I burn a lot of gas, aside from replacing the spark plugs is there anything else I should be checking out? I am also wondering about which maintenance manual you suggest, I hear a lot of mixed reviews about Haynes vs Chilton, etc. My last questions pertain to oil changes; 3000 or 5000 miles? I do a lot of stop and start in my small town ( I know this contributes to gas consumption also) and I’m never sure when exactly to change my oil, I’ve been splitting the difference at 4000; do you recommend using oil additives like STP to ‘clean’ the engine and reduce sludge?
Thanks a million, hope you are all enjoying the 4th of July weekend, be safe.
