2016 WRX - M1 0W-40 and Forget About It?

In the EXTREMELY rare instance where you would need warranty work done on the engine, such that Subaru would pull a UOA, I've never once heard of or even read about a warranty claim being denied because someone used the wrong weight oil in their car. You couldn't find me one "internet instance" either.



I tend to agree with you. If my engine blew up (I don't expect it to; this will be a "fun" road car), I wouldn't expect Subaru to be super-anal about what grade oil I used. Receipts, maybe.

Since I tend to keep a vehicle for a long time, I'm more concerned with what oil will provide ultimate protection, longevity, and, in this case, with the direct fuel injection, attempting to minimize intake valve deposits.

There has been some noise about high-calcium-content oils with these engines... Something about pre-detonation, maybe?

Also, I'm wondering about the high-SAPS content of the 0W-40 and what effect it would have on intake valve cleanliness.

If you really wanted to go the 40 grade route, Delvac 1 ESP 5w-40 has a predominantly magnesium based additive package, lower SA than an A3/B4 lubricant, yet ACEA E7 TBN levels.

How much do you get Delvac ESP 5W40 for?

 

[Garak]

I get it for about $25 a jug.

Hmm...

I'll have to see if I can find some UOAs of these cars running that.

It's not that I really WANT to run a 40... It's just that everything I've read about these engines is that they shred an ILSAC GF-5 30W.

What is wrong with a 40?

Trade you LF240s for a jug?

I almost bought a 15 Wrx but glad I didn't cause there have been a lot of updates since it's rollout. Is the 2016 pretty much as bullet proof as the Wrxs are going to get? I know they had recalls bot hardware and software and I amm seeing issues related to push button start and other minor gremlin-type issues??! I would use 40 weight and nothing less. would even consider a 15-50. anything to avoid deposits or worse, SLUDGE! (or are deposits on equal footing here with sludge?) This is why I Am throughly enjoying this Penz Ultra fill I am on now. The Dexos 1 and Honda turbo HTO-06 cert are pesky in avoiding deposits! Not to mention the venerable B5 Euro cert. It protects in both cold and high heat! remembe Rat retested it and it had the lowest drop off when he turned up THE HEAT!! ouhh!! BULLSEYE!! (there was another oil that had the lowest drop off in viscosity when he turned up the heat. I believe it was QSUD??)

Castrol Edge (black or gold) 0W30, 5W30 or 0W40 would be my vote. Been using M1, PP, Amsoil and Castrol Edge 5W30 in my 2.0 4cyl turbo application with zero issues or consumption since buying it new in 2013.

After thinking about this for a day, Delo 400 SD 15W30 has my vote with it's shear stable 3.7 HTHS.

Well, I don't know if you'll find any UOAs that readily, but you may. In any case, if one does go the 5w-40 route instead of the ILSAC 5w-30, that is one option.

Imperial Oil isn't too kind out that way on pricing?

I really never bothered speaking with a distributor. I buy some stuff from my fuel supplier which exclusively deals with Kendall/CP Products and I get some stuff from him. His prices are not too bad. I might get a hold of the Chevron Distributor but I already get a really good price at my truck parts place.

Petro Canada is expensive too. Even if I buy my fuel through them. Think they wanted 80-85$ per 18.9L for their 15W40.

I'm a pretty hardcore Chevron/Havoline/Delo, SOPUS guy, some Mobil, Kendall/CP and I like Valvoline Maxlife ATF but the stuff just stinks!. I use some Castrol but I'm not quite too fond of it.

I bought some Mobil Delvac 1300 10W30 to run in my sludger just to try. It looks like its got a hefty additive package. It was $17/4L.

Not sure what to use next. I have Shell Rotella T5 10W30 and Delo XLE 10W30 for HDEOs.

The price on the 15w-40 Petro-Canada is a little high! It's not outrageous, but it's not going to get people busting down the doors. I haven't really priced much of their stuff. The Shell distributor can do well with Rotella and Formula Shell stuff. Beating Delvac 1 is a bit of a stretch for them, though.

A lot of trucking outfits have Chevron stuff, even the PCMO stuff, and at good prices.

 

[Farmer]

I can buy Delo 400 15W40 for $67 a pail. I refuse to run Rotella Triple T 15W40 though, it's awfully stinky. As I call it "Rosmella".

Rotella T5/6 I can live with though.

Over here Chevron products are really well priced. You just have to look around. Not sure why I like their stuff that much though.

The OP can also check the Castrol lube selector. It's interesting, to say the least. It recommended Castrol 5w-30 C3 as an option for my G37, because it is SM or newer, and the manual does technically call for SM or newer, or GF-4 or newer, but not necessarily both. I guess Castrol agrees with my hair-splitting.
