My 04 gto has about 1200 miles on the oil, but its over a year old. Im about to store it for 3-4 months. SHould I change the oil before or after I store it. I'm using German Castrol 0-30...full synthetic

 

yeah always a good idea to change the oil before storage. Used oil contains acids that you want to flush out before a long sitting period. 0w-30? Does your car call for that?

 

car calls for 5-30, but lots of lsx guys use 0-30 weight oil from Castrol.....its made in germany and different than the regular castrol syntec, hence the nickname german castrol.

 

you being in a hot climate I would use 10w30....you should at least change your oil twice a year even if it sits.....use a quality filter as well like a Hastings on a wix gold...also fill car with gas and use some fuel stabilizer as well

 

I also agree with changing the oil before storage.

Mileage intervals are for normal everyday driven cars.

 

I'd go ahead and change it, it's not like that's expensive or hard to do.

 

Don't forget to change the filter also.
