Question for car guys. Truck sitting for six years. Oil looks fine. Warm it up before changing oil or change the oil first before running it?

I called Mobil corporation 20 years ago and asked them a question.

How long will the synthetic oil of theirs last.
Answer: If the bottle has not been opened then 10 years but shake the bottle up as the detergents can settle to the bottom and you can see this in the bottom of a container that has been sitting on the shelf for a long time.. you will see dark stuff on the bottom of the bottle.

After you open the bottle the shelf life is 1 year.
In an engine 6 months is it.


NOW onto the question.
Drain it cold.
No need in trying to circulate that oil.

They say the reason to change the oil when it is hot/warm is because the contaminants are suspended in the oil and it removes them better.

I have changed oil cold and hot and it made no difference in how long my engine lasted.

If you think about this for a minute.
How long does it take to get all of the oil to drain to the bottom.
I would not want that old nasty stuff clinging to anything in my engine.

I use good oil also and for my flat tappet stuff I use VR1 racing silver bottle or Driven oils.

Fill the filter with oil if you can. it gets to the bearings that much faster.

The detergents and additives in the oil are what break down.
BREAK DOWN: Do not do their job as well as they should.
You can have clean looking oil but it may not protect well.

Awesome. Thank you. Makes sense to me.

Another question for you guys. 96 Ford 302. Filthy engine. Thick with dirt and some mud. How do I clean it? My Toyotas I pressure washed once a year for decades and never had a problem. However I read these fords are different and washing that way can ruin things. So what's the best way to clean the thing? Can't work on it that dirty.

I used to pressure wash my 302, never an issue. Dont spray directly on the distributor cap. If it gets wet inside simply unclamp it and spray inside with WD-40 and wipe.

Ok. Even if it is bad I'm going to have to risk it because there's no other way to get it clean. Probably just use garden hose with spray head. Should be more gentle than pressure washer. Just need the bulk of the dirt off then I can be more detailed with it.

Cover the coil and distributor cap with a baggie or something. Scrape off as much as you can, use a few cans of degreaser and low pressure rinse/wash.

This works very well, its caustic and will burn your skin so use rubber gloves and protect your eyes. spray it all over, let it sit and soak for a few minutes and rinse without the need for much pressure. Repeat as needed. No idea why the link is labeled that way.

Robot or human?

Thanks. I'm going to do it tomorrow and let it sit in the sun. I'll post before and after pics
