oil shelf life?
 

Anyone have any knowledge about this?

I've got a few bottles of Redline MT-90 and MTL that have been in storage for about 5 years, and a few bottles that I bought about a year ago. They're all sealed and haven't been tampered with.

I've emailed redline about it but who knows how long they will take to get back to me. The shop I got the oil from a year ago said as long as they're sealed, they're good for a few years. I'm leaning towards disposing of them but just figured I'd ask around anyway.

I Would just get some new oil. No tellin if oil has a shelf life.

Redline just got back to me:

I always wondered about this anyway, who knows how long stuff sits on the shelf before you buy it.

GO REDLINE! :tup:

Redline... never heard of it, I use Royal Purple in my tC? Redline better? Or stick with RP?

redline FTW!!!

Doesn't really answer the question... :ugh2:

I've never tried any Royal Purple products in any of the cars I've owned.

I have used Redline MT-90 in my first car, it made a HUGE difference in shifting. At the time the synchros were a bit worn, especially 1st to 2nd gear. Then again at the time it was a 10 year old car that probably hasn't seen an transmission oil change in 5+ years. Either way I was really happy with it.

I've tried Redline lightweight shockproof gear oil in my 350z, great stuff. Shifting improved at all temperatures, hot or cold.

Sounds like your talking about tranny oil... not engine oil? :ugh2:

**Edit:OR is that the point of discussion is considering Manual Tranny fluid?!?! LMAO Wow, I'm slow. I thought this was in reference to Regular Engine oil... Please forgive me lol.

My question was in reference to Engine Oil.

Yes, tranny oil.

haha sorry. Redline oil is made with a fully synthetic ester based formula. nissan recommends you use an ester based oil for this car because of the vvel system in the car it sticks to the components better and has better lubricating properties. Also durring my research redline oil can withstand a very high amount of heat before starting to break down so thats why i chose this oil over anything else.. if you go on the redline website they have videos that explain everything much better than i could check it out!

I've never used Redline engine oil so I can't comment.

oh and you're forgiven. :icon17:

I think oil have no shelf life as long as it is not open before & store in a cool dry place..

"Car oil" shelf life-4 to 5 years, that's unopened!

tranceformer--Trannie oil that old, I would not use!

i like amsoil myself
