Open 5 qt shelf life

[Fa24wrx]

Hi there! I used a small amount (0.5 qt) from a 5qt jug of 0w20 PUP because I was lazy and didn't wanna go to the store for a 1 qt. I do 3k mile OCI which is about 3 months for me. Do you think the jug that was opened will be OK to use for the next change?

Sorry if this is dumb

It will be fine. I've had jugs open for at least a year and it's fine

I would be more worried about running that thin oil

Oil doesn't absorb water so being opened matters little. A year+ wouldn't bother me.

now brake fluid.. dont even use a sealed plastic container if its more than a couple years old.
Opened maybe 3-6 months.

I'm under warranty and stock. If motor pops from 0w20 then i get a new motor. My manual says 0w20 synthetic. Only can use 5w30 *conventional* if no 0w20 is available for top off, then drain and refill with 0w20 synthetic asap.

If you wish to have another “thick vs. thin” thread it’s best to start one on its own.

But there are plenty of existing ones if you care to read them, as are existing threads about oil shelf life.

I don't know why opened vs unopened would matter either way. They don't fill the bottle with nitrogen like potato chips do they?

They ask for receipts.

They ask for receipts.

You and Backstache should get together.

So you’ve had this happen to you? And they have denied your warranty claim because you used a grade that was of a somewhat higher HT/HS?

I didn't start the conversation. I've read many of them and decided with stick with what the manual calls for while under warranty

Good. From what I’ve read so far I think you are on the right track.

I've seen some stories of warranty troubles when presenting receipts of wrong viscosities. Low likely hood but why risk it? If engine blows, I get a new one. Then I'll switch to xw-30

Well, as I noted I think that’s a good idea for you.

Just ask for receipt on BOB you were out of state doing the oil change.
