300,000 miles, any oil related failure gets you a BRAND NEW( not used) motor, rental car, and installation costs oin valvoline

What exactly is an oil-related failure?

How is an oil-related failure diagnosed, and by whom?

How many oil-related failures have Valvoline covered under this warranty?

I've got 52k on 4qts of Mobil1 0w30 and 1qt of Lucas's Synthetic Oil Stabilizer with a K&N Gold Oil Filter. I should get an oil analysis. I don't have any consumption between my 5k Oil change intervals (3k during race season)

 

[JUSTINSNUTSWINGER]

I USED to use Lucas in my oil at one point like that Kev.... But if you change it every 3K.... no need. I did an oil analysis a while back (one with/one without) about 10K miles inbetween and there was no difference. Snake oil in my eyes since then.


Just sayin

I was using castrol GTX for a while in my 2004 STi and Blackstone told me I could extend my O.C.I. beyond 3500 miles...this leads me to believe that your choice of oil should be dictated by what kind of abuse you put on the car, as I was doing mostly highway/commuting driving. If I were doing racing or modifying the car heavily, I'm sure their recommendation would have been different.

I don't have time to do my own maintenance anymore, so I trust a reputable dealership and change my oil regularly, but I think for most cars that 3k number on synthetic oil is about 150% more conservative than it needs to be. I would probably start at 4500 miles and see what Blackstone said if I were using a premium synthetic such as Redline.

Thanks, I was looking around at the forums regarding the release of the "new" 2011 imprezas and figured I'd make a few cameo posts.

63K miles on my 2006 Impreza TR. From 3rd oil change up now always using Mobile 1. Engine performing and sounds good.

You have a 2011. Follow the manufacturer's specifications to the letter. What oil does Subaru say to use? An API SL? CF? What viscosity?

Follow those recommendations.

If it were my car I'd look at the two ACEA A3 choices above, and probably use either or prefer the one that meets LL-04. You are still under warranty though, so you should follow the Subaru spec. specifically. Keep all receipts.

My owners manual says 5w-30, ILSAC GF-4 or GF-5, or API classification SN or SM with the words "energy conserving"

Yes, still under warranty. Only got 850 miles on the car. I've always used Mobil 1 oil & filter ($30 on sale at advance auto) in the past but decided to do some research on this car before picking a brand since I've never owned a turbo car before.

 

[SD_GR]

Unless there are other viscosities specified (there usually are a range) then I don't think any of the oils you have listed meet your requirements.

Ya, I noticed that but I read a good amount of people use it for a wrx. Oh well, the more I think about it I just want a good oil I can get without much hassle (advance, walmart, etc..) at a reasonable price since I plan on following the 3750 mile interval at least for the first few changes then up to 5000 miles. All this reading about oil is enough to make you crazy

Let's say everyone except you in the world uses it, to make things simple. You've still not met warranty requirements. The quality of the product itself doesn't matter; for the warranty, the specifications matter.

At least while under warranty, since you will be following the 3750 interval anyway, just pick something readily accessible, economical, and within the specification set by the manufacturer.

Please check with your dealer. Subaru has changed the requirements for the 2011 turbo models. They now require full synthetic 5W-30 oil changed every 7500 miles. I wrote Subaru to verify, and that is what they said. The owners manual were printed before the requirement was changed.

I did read about that and called my dealer. Talked with the service manager and he said that is the maximum interval for the car under normal operating conditions. However, he said if it was my car I wouldn't go past 5000 miles. I am still unsure about what brand to use. I've used Mobil 1 5w-30 in my Frontier with no problems but after some research it doesn't seem like a good choice in a wrx. Shell Rotella T6 has plenty of good info behind it but I only see 5w-40 available. I would hate to pay top dollar for Subaru oil from my local dealer because they are pricks.

 

[Donkey]

Thats because it is made for Diesel engines.

 

[Eric05mx]

Ya, I seen that. Should it not be used in a gas engine? I see alot of talk on the wrx engine shearing down a 5w-30 to a 20 weight so they use a 5w-40 like Rotella T6 with good results. I've always seen plenty of post about Subaru's burning mobil 1 like crazy.

I know this subject is really wore out but I am new to Subaru and want to make the best choice for my car.

 

[Legacy01]

BUMP THIS....Shell Rotella T6 is good stuff. To add a bit, the only oil I've heard shearing on a turbo car is Mobil1 5w-30 down to a 20wt. I guess it really depends how you drive, how often you change your oil, etc. I know Mobil1 has their 5w-40 as well, but I've never used it. I usually stick to either Rotella T6 5w-40 or Valvoline full synth with no issues...
2005 WRX, 62K, no issues.

As a guy that makes his living advising people in the oil industry, including people such as the King of Saudi Arabia, any stories of a particular oil causing engine failures is ridiculous. The oil isn't doing it. That particular engine may have had issues that caused it to fail earlier than others. Tranny fluid or brake fluid or any of those others are a different story, but engine oil is engine oil. Synthetic is better than conventional, but in general, no oil if properly maintained/replaced will ever cause a failure. They're all too similar to ever blame one for an issue.

But what do I know, I've just made a quarter million a year+ for years doing this job. Listen to gossip or listen to somebody that knows.
