24's and 0W16. Straight from Subaru

Got a call back from Subaru Tech Support about the 0W16 oil. The guy said they were getting a lot of calls about this. Using 0W16 is just a recommendation for best fuel mileage. Using 0W20 will not affect your warranty and its perfectly fine to use. He also said the owners manual could have been worded better. Hope this helps

5W-30 is also probably OK. I'm not aware of any major changes to the engine, they're just trying to adhere to CAFE.

Absolutely no offense intended, but my experience as a construction manager is that anything said but not put in writing didn't happen. Legally.

I certainly agree that 0w20 isn't going to hurt the car, and 5w30 is fine too. I just wouldn't want to end up arguing with someone official about a warranty claim and my only backup be that someone told me X, I swear.

It is also worth mentioning that I'm sure no one could prove what oil you ran once it's been used for a while. So an individual could choose to use 5w30 and then lie about using 0w16 for a warranty claim, and I don't think they'd be in any risk of being found out.

It always feels silly to me to put a 0w oil in a car in Phoenix AZ. On the coldest day of the year it might get to freezing, briefly, at 5:30 am.

Well, I assume that if there鈥檚 a warranty claim they鈥檙e going to want to see maintenance receipts. If all those receipts are for 5W30, I think they鈥檒l find out. ;)

Why would they care if it was 5W-30?

I don鈥檛 know what it says in the 鈥24 manual, but for the earlier ones it only says you鈥檙e allowed to top up with non-synthetic 5W-30 if 0W-20 isn鈥檛 available. You鈥檙e supposed to refill with 0W-20 at the next oil change.

I鈥檓 not saying it鈥檚 a big deal, or that Subaru will care, just that they could find out from your receipts when they ask.

I think Subaru recommends other oil weights in other countries. IMHO the recomendation of 0W-20 is driven by CAFE.

Yes, 5w-30 is spec'd in Japan where they build the engines.

I get the dealer to change my oil, but take my own oil. On the receipt it says customer supplied oil and nothing else. Who knows if that would matter.
The only weights referenced in this thread are 0W16, 0W20 and 5w30. I use 5W20. So that makes me "out of step" with you other oil users.

Okie! I was hoping you'd chime in here. Care to share your wisdom regarding choosing 5W-20?
I have spent a percentage of my career as a maintenance engineer (power generation) on lubrication. I have seen it all in terms of catastrophic bearing failures.

I can tell you that using 0W/5W/10W-30 oil is the best way to go. But to each his/her own

Please elaborate and/or link to a previous post for more info on using 0W/5W/10W-30 oil. Thanks.

I've been here for a while, and on other forums, and have seen people show up and make claims. If you can provide some evidence other than your own opinions I'd like to see it.

That you are literally funny? I lose, you win.
6 Crosstreks later, still using 0-20. Costco has the good Mobile 1 synthetic.
I get the filters at the dealership.

i think the coldest weather i've ever been in was 5 degrees at south grand canyon

I'm compliant with the "20" recommendation. However, I live in a warmer climate hence I am taking liberty in using the "5". 0W20 covers climates from the poles to the equator.
