Old synthetic oil in garage. - Dodge Diesel

cozzo1000 · 03-23-2012, 01:20 PM

I have a case of Amsoil from about 12 years ago that I bought to put into a racing car. The car has been sold and I never used the oil. It's Amsoil 10W-30 and it says "Turbo Formulated" on the case. Is this OK to put in my truck? Or is the oil outdated? I don't suppose oil has a shelf life.

Any thoughts or help?

Hoarder much? lol

Just kidding. I've always wondered if oil had a specified shelf life as well. I guess you could send in a small sample for oil testing and see how the results turn out.

I would think after sitting for so many years something inside must start to break down?

Yep - that's what I was thinking..... break down. It's also aged technology and might not be good for more modern diesel engines.

Because it's sealed I would think it's still OK. You can go to the Amsoil web site and there is a spot to ask questions. As I use Amsoil I have asked a few over the years.

It needs to be formulated correctly for a diesel. Gasser oil won't work well in a diesel. It can't suspend the soot in the oil which will increase wear alot.

I see SJ-CF ratings on the bottle. I don't think that is what is required for our engines. CI-4 rating, if memory serves me correct, is more like what you would need.

I believe S= spark ignition(gas) and C= compression ignition(diesel)

so that oil would be good for gasser not diesel
