I generally change my engine oil on my 2001 Sahara 6 cyl around 3,000-4,000 miles within 5 - 7 months but due to my hip replacement and the wife's cataract surgery the Wrangler currently only has about 500 miles since the last change in January 2012. We did make one short trip to Arkansas but mostly it has just set in the back yard most of this time. Wife did drive it to the market a couple of times.
If we get to take a vacation in September we'll probably put another 1,500 miles or so on it. I'm using Castrol 10W-30 oil and Wix filters (which I already have for the next change) and was wondering about the fesibility of waiting another couple of months to change the oil when it will have approximately 2,500 miles and be almost 9 months since the last change. Owner's manual says 7,500 miles or 6 months.
I don't mind the labor or small expense of doing it now but just don't want to unnecessarily waste the oil.
Any suggestions or opinions on this next oil change?
