I will be putting my 07 GT up for winter shortly, it is stored inside a dry barn. I have 3000 miles on the oil in the car (Mobil 1 synthetic). I put a battery tender on the car and start it about every three weeks and let it completely warm up. Am I better off changing the oil before I store the car, or changing it in the spring before I hit the road?

 

if it was me i would change it now and then when you use it again lol but im a freak

 

I would change it now aswell

P.S I HATE WINTER

 

Winter blows ***. That's all I have to add.

 

I would change it now and when you get her out.

You think not being able to drive just for the winter sucks? I am getting deployed for 7 months next year.... I dont even know where to start on what to do to the stang to keep her healthy.

 

Change it now only because she'll sitting for an extended time without burning off any moisture in the crankcase. It's the same methodology you use with your yard equipment: Change the oil prior to storage.

Edit: My bad. Didn't notice you said you'll run it to operating temp every 3 weeks. If so, you can forego the oil change now if you want. 3000 miles on M1 is fine if you'll be doing that. Just do it in the spring.

 

I certainly miss driving it in the winter, but there is a large salt mine nearby, and the town I live near is nothing but hills, consequently there is always salt on the roads in the wintertime.

I get the snowmobile out for the winter and get my jollies riding that.

 

Winter? What's winter? Oh that's right, I live in Florida. You crazy guys with your seasons.

 

With semi-synthetic oil, you're only about 1/2 way through it's service life. I would leave it there, and change it in the spring. The reason for changing oils in the past is that they become acidic, and can damage bearing surfaces. But modern oils are so pH stable that it's not that big of an issue any more.

Also, I would not start it every three weeks. Just connect the battery tender and leave it alone. Make sure you get the tires off the ground so they don't flat spot.

 

What's all this talk about "Winter" and putting your Mustangs away for an extended period?

It was sunny and mid-80's here today and it will be sunny and in the 70's come January. You guys can keep that stinking winter thing up there.
