Re: V-6 or V-8, regrets?

Just turned over 400 miles today, about half interstate at 60, the other half city. I've been switching between the three modes a lot in the city, but stayed in eco on the interstate. Averaged slightly over 20 mpg. I'm happy with that.

Okay. Titan, indulge me and confirm the numbers for me but let's say that in my case it will be 15k driving a year and about 70% city and 30% highway, gas prices in El Paso, TX are $3.30 reg in average and we are about 3,700 feet altitute. What would be the cost of the V8 over the V6 on a year per year basis. Let's disregard the initial cost to get the V8 engine. However I would like to know the additional cost of owning the hemi on a per year cost on maintenance, I keep hearing 16 spark plugs every 30k miles driven. What will that be to change spark plugs with OEM replacements and any other maintenance I have overlooked.

My previous vehicles have been 84 toyota supra, 87 toyota supra, 93 mazda 929, 2004 bmw 330ci, 2008 infiniti G35 journey and 2002 mitsubishi montero sport 3.5 liter V6. As you can see I have never owned a V8 engine but I drive the Chevy Tahoe with V8 engine at work almost exclusively. I also drive F250s at work with gas V8 and diesel power strokes too. The G35 is my car that I use all the time and the Montero sport is the wife and will be the one the JGC will be replacing.

Jeepgarage has me more addicted than a crack head to crack and I have looked at fueleconomy.gov and fuelly websites and check and compared and analyzed and completely gone a millimeter away from insane trying to decide but I just can't.

*Papote sheds a tear then breaks down crying*

To make it more complicate it everything I check shows me that the Montero sport V6 3.5 liter engine gives same mpg as what the MY14 Overland 4x4 hemi will give. I do not tow anything but may buy a couple ATVs in the future to play on weekends and do want to go off roading every once in a while.

Decisions, Decisions, Decisions...

Sorry in advance for long post and thanks in advance for checking the numbers.

Re: V-6 or V-8, regrets?

Holy smokes..lol... there is a spreadsheet that someone put together on here that is awesome and breaks it down for you between all three engines if I recall correctly... I would do a search on that and plug your numbers in... the factors of altitude should be about the same on both engines, so I would say it cancels itself out between the two.

Your cost of maintenance will have to come from people that have owned the engines for multiple years, perhaps some sample guys and gals with V6 and V8's can chime in on what it cost them, but I have no idea.

16 spark plugs!!!!! In 30K!!!!!! What the....first of all, I hope thats just someone who had serious issues with their engine, and second... well, I don't have a second.

I would say just buy what you want... the cost of fuel does not sound like its your biggest factor... drive them both and just pick... good luck.

Yeah I also blink a few times when I saw the spark plug change thing. Can't remember which thread I saw it at. Unknown if it came from the owners manual or service manual.

I'm scare of driving the darn V8. May like it too much. :-)

Well, maybe take a look at the SRT fuel mileage and then compare the 5.7 V8... that should make you feel much better.. lol.

Or, always drive downhill...

Also remember, that the maintenance on the Hemi is more. It takes 16 spark plugs that should be changed every 30,000 miles vs. the 6 which should go to about 96,000 miles, even though I wouldn't wait that long.
I knew I read it somewhere. Here it is on 1st page of this very thread.

Re: V-6 or V-8, regrets?

This is absolutely insane. Are they dismantling the engine to get to those 16 spark plugs? I'm no mechanic but most engines i have seen have spark plugs very accessible on left/right top park of engine.

Let us hop in your time travel magic ball sir and share with us what you going for to replace your wk2? Possibly looking at all new wk3 or whatever it will be call the new JGC or something else?

Just curious.

Re: V-6 or V-8, regrets?

I have no idea what will be around then... but if I was to guess based on what is out there today, I would say it will be the SRT JGC. I really wanted it and came so close, but I just wasn't sure enough that I wanted to sleep on the couch for a while.

My wife said she was fine with the Grand Cherokee, but when I left to buy it, she specifically said not to buy the one with three letters...lol. By then I will be able to work on her...

Its also quite possible that both of our dogs will not be with us, and the only reason I need an SUV is going to our cottage on the weekends so the dogs can be in the back. If they are "retired" by then, I will look at the M3 sedan... thats my end game car.

Re: V-6 or V-8, regrets?

Just picked up my 2014 GC Overland in Central Florida three days ago. It is black with the indigo/brown interior, and it is beautiful.
Trip computer showed 22.5 average mpg driving state highways back to South Florida. Really not bad for a hemi.
Also have hemi in 2011 Ram Express pickup. definitely sounds better in the truck.
