Accidentally used 5W-20

[alenk13]

Own a 2022 Jeep Wrangler JLU Sport. Went to go buy 5W-30 oil today and the container felt a little light on so I grabbed the one behind it….after putting it in, I realized it said 5W-20. Am I screwed?

Edit: 3.6L engine. Live in New Jersey

You've the 2.0T in your Jeep? I ask because 5W-30 is the sole oil specification for that engine.

Personally, I'd take one for the team and replace it with the correct weight. It's up to you if you want to do the same.

I’m sure you’ll be fine… that said, I’d probably drain it and refill. It’s a $40 oops, not the end of the world

I would recommend just draining it out and refilling it with the correct oil. Not the end of the world though!

@alenk13

0w20 is what you are supposed to be running in your 3.6.

Proper fill is exactly 5 qts. of oil.

I assume its cold in NJ right now? 5W is the viscosity for the Winter. So, you're fine. Change it before it warms up if you're really worried.

thats a plot twist lol. I used 5w-30 the last time I changed my oil. but Im reading that -20 is suitable for the 3.6l

can't predict the weather here lol. One day it is, one day it isn't. But typically cold until late spring

No harm no foul using 5w30 last time. Use 0w20 from now on.

Use that year round!

i dont think its critical. as long as you have the right amount of oil is the main concern. id leave it till next time.

Yup, used 5 quarts. Thanks for the reassurance

Isn't 0w20 specified for the 3.6 now? If that's the case, 5w20 really isn't that far off. It's still 20-weight oil. 5w20 was also the previous spec for the 3.6. GO figure.

You are correct 0W20 is the recomended oil. However,

This, it'll be fine. The only reason they specify that lightweight oil is for fuel economy reasons, you don't actually need to run oil that light. I don't know what oil is in my Jeep right now because it's whatever the dealer put in that I bought it from. What I can say is that at 15,000 miles it's getting Motul 5W30 put in it. And that's what it'll get from now on as well.
