to change oil or not????

[landrovered]

This is not a diesel dump truck with half a million miles. OP is talking about a 2000 with 57k and less than 1500 miles on the current oil.

But in typical hyperbolic internet forum fashion the comments make it sound like actually using the car before storage will damage the champagne molecules in the magic virgin snake oil and cause the interior of the motor to turn to goo. Also the guru competition has been swift to arrive in this thread. One of my least favorite things about the 986forum. Other sites are not stuck in this dynamic.

That being said...I would proffer that 1500 mile oil that is circulated around the motor from time to time coating said goo inclined parts is far superior to any 29 vestal virgin oil that sits in the sump from December to May.

I started a 993 recently that had not had any special storage measures taken and had not run since 2010 other than being kept in a temp controlled garage and guess what, after the usual precautions and fluid changes it runs like Thor's Hammer. If old oil was as detrimental to the engine internals as is indicated in this thread, Thor would certainly show it.

So if you guys want to argue about how many oil angels can sit on the head of a pin then go ahead. OP: keep the 1500 mile oil and start your car twice a month. It's not the oil I worry about it is the gas that will turn to jelly.

Then long term effects of acidic oil wearing on my original ims bearing which is sitting in it all winter are why I find it necessary to change my oil before and after storage. This is best practice.

If it was Joe Gibbs oil that was costing me a fortune I might rethink my procedure. But since I get my Castrol edge fairly inexpensively it's a no brainer to change it because I like my car and I like the peace of mind. Oh and also the consensus from experienced porsche mechanics is that you should change your oil before storage.

This is fun. And funny! What about gear oil in the transmission? Sounds like it should be changed twice a year as well - lots of metal, oil and heat. My personal favorite is the slap to the poster with "only 10 posts". Is it the consensus that he's an idiot, cause with only 10 posts, how could he know anything? Now I fear I'll be shamed due to lack of posts. What is the minimum to be one of the "guys" here? I feel like a victim of Lackofpostsism, and we need the DOJ on this stat!

JFP in PA is one of the most knowledgeable porsche experts on here. So if someone shows up to this forum and starts to question his well researched thoughts and experience with no solid information, yeah, that makes that person seem like an idiot.

The Copernican response. Understood. I shall remain silent. No questioning or opinions.

If you have opinions that contribute to the conversation or bring new light to a subject I'd love to hear them. If you feel like spouting ignorant crap out of your mouth through your keyboard and you want to call someone an idiot who knows what they are talking about, then I look forward to your silence.

Well, well. Aren't you something. All of this over the knowledge that somebody else has. Man crush? This vitriol over changing oil in a car that's at least 11 years old. I have had the opportunity to spend time with a Porsche. One of the good doctor's grandsons. In his words, the people who are fanatical about his family's cars are mystifying. And comical. It's just a car. They don't get it. Me neither. Does this qualify as new light? See - it is fun. And you're funny.

The minimum is to not detract from the forum as you are attempting to do.

If 1500 miles will create acidic oil then why do we not drain this caustic poison from our engines all together? And this is not 1500 miles on jiffy mart 99cent oil, this is full synthetic oil which once upon a time many manufacturers specified a 15,000 mile service interval. We don't drain it though, we run it and coat the insiders of our engines with it so that it can protect the metal from friction and RUST.

Sitting engines lock up because the pistons seize to the cylinder walls and water from condensation from temperature changes causes rust in the bearings, valve train, chains etc. To properly store an engine you mist the cylinders with oil to prevent this, no one has mentioned this practice in this thread but hey, what do I know.

Once again, starting or simply turning the engine over to circulate oil will do far more to protect your engine than anything else. I would not throw out 1500 mile oil if I were the OP.

You guys can do whatever you like, they are your cars and I don't fault people for erring on the side of caution but I think it can get silly when you throw perfectly good oil away twice a year without testing it. If the data says its old then it's old, otherwise it is a waste of money.

And they were wrong.

This may be correct if you can run the engine up to temperature and get a good 20 minute run cycle. Otherwise you do more damage to start it than its worth. And as the reason I'm storing my box is due to inclement weather...so that's not feasible. Again, I get what you're saying here, but you haven't convinced me that my regimen is worth altering.

Actually not, given proper filtration synthetic oil can last almost indefinitely in terms of viscosity, the problem is the additives break down and no longer perform their intended function.

This entire thread is confusing the function of oil in a stored engine. A running engine needs to be protected from thermal breakdown of the oil which creates varnish and other compounds to form. Detergents and additives are added to decrease the effects of shear and reduce deposits from thermal breakdown amoungst other things.

In a stored engine rust prohibition is the primary function of oil. It does not need to provide lubrication to reduce friction as there is none, it does not face thermal breakdown from high temperatures, it can however be subject to waxes forming and crystallization of certain compounds at lower temps.

This thread has talked about acidic compounds forming in oil. Motor oil has a ph of 6, gasoline is an alkane which is inert and thus has a ph of 7. So if you were to pour gasoline into your motor oil it would not make it acidic, it would make it more basic so the acidic problem referred to earlier is a non sequitur.

I submit that coating an engine internally with a kerosene and paraffin mix prior to
storage would do a better job than the most expensive royal purple if the Royal purple simply sat in the sump.

Look at the old jeeps that were shipped in crates and coated with cosmoline. The US army knew how to prevent rust and corrosion.

And JFP is a smart fellow, so smart he does not need you guys to tell everyone how smart he is for him.
