7 year old Mobil 1 oil, looks fine, change?

[ArtDecoWorld]

I picked up a vehicle (1983 Dodge Rampage) that has Mobil 1 Oil from 7 years ago in it. The previous owner kept the vehicle in a garage, for the most part, and it wasn't driven much in that time. The oil is still clean and golden-looking. Filter is also Mobil 1.

He says it's fine. What say you? Can the vaunted Mobil 1 hold the fort for 7 years?

Thanks

If it were mine, I'd change it for peace of mind.

Why would you even risk it? Change it.

You can always pull a sample and test it. You could even pull the filter and use that as your oil sample source if you dont have a pump. I'm willing to bet the oil is just fine. It'd be neat to verify either way via a UOA.

A UOA would cost more than buying new oil.

Change it and the filter.

If you decide to change it you should at least use it long enough to stir up anything that's settled. I'd use it for at least a few hundred miles.

A UOA will prevent you from dumping good oil in the future though.

Good luck with the Rampage! I wish I could find a solid one here on the east coast.

If you plan any engine or fuel system work, do all that first and then change the oil.

Well, that's if there was a useful amount of miles put on the oil, or if the user is thinking of going another 7 years without an oil change.

I'd only change the oil filter. Its media contains mostly cellulose paper (some glass fibers too). The oil itself is fine, not undergoing hot-cold cycling and combustion, etc.

Congrats on finding the ugliest car ever made! OK, maybe the Gremlin was uglier, not sure....

Its cool though, a redneck dream, El Camino-mini!

Seriously though, I wish they made El Camino -style cars these days.

Yes change it but - run car up to operating temp, then change it. The purpose is to let all of the surface rust, and particulates wash into the oil.

7 years and you guys say leave it?? Ok.....

Change it. In fact I would not run it for any length of time until I changed the oil filter. a C&P of that would be great!

 

[BigCahuna]

Blackstone doesn't say to change oil based on age, only time in service. How many miles are on the oil?.,,

Yes, you can tell it's not their car we're talking about.

No question in my mind... change it.

I've learned that *WHENEVER* I ask a question like this, that I'm better off doing it. So, if it's not going to cause you to miss a mortgage payment, then change it!

Filter should be changed - so change oil then ? - or just do a short OCI post filter change ...
