My max is at my dad's house in another state and I haven't been able to go there in over 6 weeks. Every weekend I'd usually start it and let it run for a while just to get everything moving until I get my license. So, it hasn't been started in over 6 weeks, could something go wrong if you don't start your car for a while? Just curious

 

if anything starting it every weekend is bad for it, all youre doing is getting moisture in the oil. cars have no concept of time, if youre planning on letting it sit for 2+ weeks disconnect the negative battery cable, thats it

i park my cars in October for winter. all i do is change the oil, disconnect the negative battery terminal, and 6 months later in April i hook up the battery and off i go

 

How long will it be sitting before you start it again? I've let cars sit for a month to six weeks between drives to burn out any moisture build up. A good battery kept me from needing to jumper the car when I got around to starting it.

Like Chrome91 indicated above, it is best to keep the battery disconnected. I would check tire pressure before driving it.

Since the Max doesn't have hydraulic lifters, you won't be hearing any lifter noise when you start it like some other engines that sit for a while.

Are you in a cold climate where you need to verify antifreeze is good for freezing temperatures?

I would check the oil and fluids before starting as a matter of course.

I knew someone who parked their Honda in a barn for a couple of months. He returned to find a nest of rodents that had made a nest under the hood and chewed up the knock sensor wiring. A good working barn cat would have kept that from happening. Ha!

 

^^^^^THIS^^^^^

 

how about if you let it idle for a few minutes until warm and then after it's warmed-up, keeping the rpm at ~ 3k with short burst to 4K and down to 2K every few minutes and running it a total of about 15 - 20 minutes? wouldn't this burn of moisture/volatiles from oil and allow for charging of the battery. also, move it slightly so that tires don't get flat spots on them. wouldn't this be better than sitting for months unstarted/unmoved?

 

I had a work truck that used to sit for 2-3 months at a time between uses, never had a problem due to sitting. No flat spots, or oil problems. I did seem to go through batteries faster, but that could be due to something else besides sitting. Don't forget with the additives in gas, it goes bad after a month or so, so don't let it sit for three months on a full tank.

 

theres still absolutely no point in running it. running and revving it constantly like that stationary without load isnt good for it either. just disconnect the negative battery cable, if the battery has to stay connected for whatever reason get a tricke charger. make sure the tires dont go completely flat and they wont get spots

sitting for months hurts nothing. my Crown sits in a parkade under a car cover from October-April with the battery disconnected untouched. starts up in April like nothing ever happened. my old Hardbody sat untouched on a farm for over 5 years abandoned, when i bought it the guy connected the battery and it started on the first crank then i drove it home on the highway as-is. even my Hilux sits infront of the house months untouched and i keep the battery hooked up to it and it doesnt care
