How much gas to leave in tank when away

chaolin2007 · 09-17-2010, 01:02 PM

I'll be travelling for a week (one week too many to not drive my car

) Right now my tank is 1/6 full. should I put it to full? or it doesn't matter at all?

Thanks,

If you are just going to be gone for 1 week. It makes no difference either way. For longer term storage (ie. 3 months or longer) filling the tank helps prevent condensation which can cause rust on tanks and fuel systems.

go to your dealer and they will prep the car... Well that's what the manual says..not trying to be facetious either

1 week won't matter

I was gone for 5 weeks and I didn't do shit...

I'll just fill it full. Thanks.

For shorter periods it's ok to leave it close to emtpy.
That way if someone steals your car, they might even run out of gas.

unless you live next to a gas station... DOH!!

doesnt matter at all unless you are going to leave the veh parked for extended time. like several months, then there are a number of things you can do. fill fuel tank, use fuel stabilizer,change oil and filter,put veh on a battery tender, over inflate tires to prevent flat spots or even set it up on stands just for a quick incomplete list.

I'd be curious to know how they prep. I can't imagine anything that can or should be done.

Simple, They should be paid. Thats what should be done!

Sorry, rant off- Im just not too thrilled with dealers lately.

Unless you're leaving it for months and months, it doesn't matter. If you're parking it for an extended period of time, the tank should be completely full.

Mine is sitting idle till the begining of Nov.

I topped it off, and made sure the tire pressure was ok. My gf might drive it occasionally. She had to back it out of the garage last week, and I told her to let it run for 20 min the in driveway.

Edit: I almost forgot! I need her to take it to the dealer and get the summer tires off, and put on the all seasons for winter..... so I can drive it when I get back!

Letting is run for 20 minutes and not driving it? Not a good idea if you ask me. You need to drive it and warm up all elements: gearbox, drive shaft, bearings, differential, etc. Your car can easily sit for 6 weeks without a problem. You do need to drive it though for 20 minutes or so after those 6 weeks.

Alternatively, if you have no one to drive the car, buy a modern battery charger. Crank up the car after 6 months, let it run for maximum 2 minutes in the drive way and start driving immediately. Easy on the gas, not too many RPMs and after 10 miles of gentle warming up, your baby is ready wake up all horses again.

Never idle your engines, drive it.... unnecessary long idling from cold starts will carbonize your precious injectors...
