Why change oil again after storage ?

[DUKE]

I know why to change the oil before storing the vehicle. Not sure why to change the oil again before driving it, if it hasn't been started at all while stored? Also, does it really matter if I put regular oil in the car while stored if I use Royal Purple synthetic oil when it's up and running?

Thanks-

If you store your car and never start it for like 3 or more months moisture will build up inside your motor and contaminate your oil as well as giving your engine a lack of proper lubrication reguardless of what oil is in it. I would start it and let it run and get up to operating temp. to boil away all the moisture that has built up at least once a month. I would continue to keep synthetic in it as well.

Oil breaks down. That's why it's X miles OR X time, whichever comes first.

Whether you actually have to change it after storage, I'm not sure...

I think the absolute best thing is to use synthetic and have it started and run for 10-15 minutes once every other week. If you can't do that, use synthetic unless you're replacing the oil before you drive it again.

cheap insurance if you ask me

You don't have to change the oil..no condensation will buid up in there over the 3-5months worth worrying about, you can drive it safely..however if you start the car every few weeks then you open the door to condensation getting in the engine because if your going to start it then you need to run it for at least 20minutes to do any good. Besides why would you want all those dry starts every 2 weeks when you can have just one in the spring. Trust me, go coat a screw with oil and leave it in a jar for a couple months..I bet the oil is still there when you get back..hence the engine will be fine not started. Now I do change my oil after 100miles of running it in the spring but only because I don't change it before I put it away. Just my .02$

When storing the car it is necessary to start it every month or so at least to make sure all internal parts are kept lubricated.

After running it for 10-15 mins or however long you do and then shutting it off and waiting till the next time you fire it up condensation builds up in the engine and naturally it drips down into the oil. If you don't change it, probably not much would happen but it could create some stickiness (valves, lifters, etc.) if you don't.

You don't need to lube the internals..they are coated from running all along..oil will not evaporate, you don't need to start it and infact will do more damage if you do.

EEEEEEEEEE..........sorry wrong guess, would you like to go for double jeopardy where the scores can really change?

Really, what area requires oil?? I have cracked open valve covers of vehicles sitting for years and the oil is present..I sell tools for a living and I know without doubt an oiled tool will not rust,oil will protect it for years after coating. Do you really believe the oil will float away? what portion requires oil because everything coated with oil during the last run is still covered I assure you. My last engine had 200,000miles on her and this was the proceedure I used on it and what do you know it had 125 compression throughout when we pulled her. Please explain to me why the car must be started rather that left to sit? also if your going to be starting up the car every week..why would you need to change oil come spring? Also in regards to above mention of "boiling away" moisture..um starting the car creates an enviorment for condensation, your heating up the engine which now comes in contact with the enviorment which is 32deg or less, then your going to shut her down...tada as the cold dense air colides with the moist hot exhaust and combustion temps they condense as they cool and BOOM condensation. A cold engine will not have condensation on it...example go into the garage in the winter and pull your intake..is it wet inside..no why cause there is no issue to cause condensation.

Agree 100% . I change it when I store the car and don't start it till spring. Sythetic oil can go a lot longer "time" wise than regular oil.
