We have a 10 year old Honda Odyssey that we keep just for long road trips and it has gone 3-4 months without being driven with no issues. I usually do try to fire it up every 1-2 months just to make sure the battery gets a charge and to avoid long term storage issues around oil and belts and other parts that degrade.
Thanks, that's good advice. Luckily we've burned a tank or so every road trip (every few months) but I was wondering about that and whether it was good for gas to sit so long.
