First oil change?


Recommended Posts

I have a new 2013 legacy sport, I thought the first oil change was supposed to be at 3000 miles second and 7500 and every 7500 from there, is this correct? The calendar on mysubaru says first at 7500 so I just want to make sure before I get the oil changed tomorrow. Thanks!

That is what I did on my 2012, 1st OCI at 3,000 miles, 2nd OCI at 7,500 miles. I wasn't really comfortable with the 7,500 OCI so I switched from dyno oil to syn oil for piece of mind eventhough the N/A engines do not need syn oil.

You are referring to "break in oil" which is not used.

Depends what you mean my "break-in" oil. If you're referring to an oil that is different at the factory than what you get from the dealer, then yes, a break-in oil is used and is fine to run to 7,500 miles. This is from Idemitsu Lubricants of America:

 

You ask some very good questions which I will answer in “generalities”. First, just so you know where the information is coming from, Idemitsu supplies most of the OEM’s for both Factory fill and service fill....

 

OEMs specify Moly in their factory fill formulations to increase fuel economy during the initial period. In general a factory fill formula will be more robust in the additive treatments etc. This is done for a variety of reasons which I will not go into here.

 

Some of the service fill formulations also contained molybdenum however, with the transition to the ILSAC GF-5 specification, most 0W-20 service fill 0W-20 formulations now do not have Moly. That being said, you are always safest following the OEMs recommendations. All service fill OE formulas that we supply have been submitted to a full battery of tests at that respective OEM’s R&D facilities in Japan and have been approved.

A used oil analysis on the factory fill will also show that it is more robust in moly (also in the assembly lube), zinc, and phosphorus, than the dealer Idemitsu Subaru oil.

I just purchased a 2013 Outback last week and I have the same questions on oil. So is the Idemitsu Subaru oil good to use or is Amsoil better? How about Castrol Edge? It the info above it seems I need to find an oil that is high in moly. Right?

 

Thanks for your input.

I've always made the first change around 500 miles to get rid of any debris from the engine manufacturing process. I don't think I've heard the term "break-in oil" in many years.

 

This is what a lot of us have been doing for decades.

 

You guy's should be fine with any name brand synthetic oil. Just be careful with Mobil1 5w-30 it breaks down to a 5w-20 in a short amount of time.

 

Amsoil's site has some good info if you want to read.

 

I would think that the 7500 miles should be fine with a good oil.

 

My OEM GT engine went 154,000 on dino oil with no bearing noise or other issues. I replaced it for oil usage (rings). But I would go as far 5500 miles on the dino oil in the winter time and 3500-4000 miles in the warmer weather. BTW most of my miles are at highway speeds.

 

The main thing is keep it topped off. Don't go 7500 without checking the oil level.

305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD).  CHECK your oil, these cars use it.

I was talking to one of the guys at my local Subaru dealer today and they said that Subaru may be sending out a notice that the OCI should be 5K instead of 7,500 miles. It's becasue people are not checking the oil levels between changes and the thin-as-water 0W-20 gets consumed, then the oil level light comes on. I may do that. At that rate I'd be changing it 2X a year. My wife doesn't put that many miles on her cars, but it's mostly city.

Rather than shorten the service interval, it would make more sense for Subaru to allow the use of thicker synthetic oils for hot climates, and/or for sustained high speed driving. If you went from a 0w-20 to a 5w-30 synthetic, I'd only expect maybe a 1.5% reduction in mpg, ie almost down in the noise level. With a thicker, even less volatile 10w-30 synthetic, you might take a 2% hit.

Hi Tooslick,

 

Good to see your expertise on this thread. I agree with yo 100%. I asked the dealer about going to a thicker oil, but they advised against it because this is what Subaru requires. I guess the dealer can't advise me contrary to what Subaru says, but if I go to a thicker oil and I end up with engines problems due to the thicker oil, Subaru has the right to void my warranty. I don't see how 5W-30 would give me problems, but you never know.

 

How would 0W-30 work? That way I would have the cold start-up 0 weight then hot temp 30 weight. I much prefer the 5W-30 idea. It's also more readily available in various brands. The question is, is the reason Subaru went with a 0W-20 tighter tolerances in the engine, smaller galleys, etc. or just plain gas mileage. If it's tigher tolerances, I'll stick with the 0W-20. If it's gas mileage, I'll use the 5W-30 and take the 1-2 mpg hit for tha sake of better engine wear.

 

The debate goes on.

The same engines sold in other markets such as Europe and Australia still recommend 5w-30 and even 5w-40 grade oils.

 

One other design feature contributes to the relatively high oil consumption. The "hypereutectic", aluminum pistons have a high coefficient of thermal expansion ("CTE"). In order to achieve the correct tolerances when the engine is fully warmed up you have to size these parts to fit loosely in the cylinder bores when the engine is cold soaked. This is why you hear audible "piston slap" - even in just moderately cold weather. I strongly suspect a fair amount of the oil consumption is occurring during the warm up phase, due to the sloppy fit of the parts. Using a slightly thicker oil such as a 5w-20 should help to mitigate this source of oil consumption.

 

A 0w-30 will also help to reduce oil consumption. This grade tends to be less volatile than 0w-20 and it will give you a thicker oil film at the piston ring to cylinder interface in a hot engine.

 

I'd wait to see how your engine performs before making any changes. But trying either a 5w-20 or 0w-30 synthetic would be my first response for abnormal oil use in a vehicle that only specs 0w-20 for all ambient temp ranges.

Thanks for all the detail. It's very interesting. I may just go with a 5W-30 synthetic for the first oil change with the Subaru filter. With summer around the corner 5W-30 should work well from what I gather from the sloppy fitting pistons.

 

If I go with 0W-30 in the future I may just go with Amsoil OE. It's actually cheaper that the Subaru oil at $7.49/qt.

 

Thanks again for all your contributions.

We used to be proponents of changing the first set of oil at 500 miles but after doing a bunch of research, 2000-3000 on the initial oil is a better way to go because the initial fill has conditioners in there that you want to keep in there a little longer.

 

As for what oils to run? We have always liked the Amsoil for >7500 OCI coupled with the Amsoil filters. For a more cost effective alternative, we started running the Motul C3 X-Clean about 3 years ago and the Blackstone Labs results from the Motul have been as good as the Amsoil on 7500mi OCIs.

 

We stock the Amsoil and Motul and can drop ship the Motul if anyone needs it!

Remember the oil filter is just as important as the oil. The better it filters, the longer your oil will protect.

 

The G/F's 2013 WRX, 1st OCI is 3000 & every 7500 OCI there after.

I was on my way back from Kansas City today and my check oil light came on. Im at 4500 miles. pulled over to Qt and I was about 3/4 low from what I can tell. I had to add 5w-20 to get by. I am debating on whether to go to the dealer for first oil change and to check for oil leak?

Who here has a solution to not get raped at dealership for a 30,000 mile check up. Mine is coming soon. Dealer by me is shady...definitely not going there. Plus labor is too expensive. What does my 2011 Legacy 2.5i Premium need at 30k?

 

 

Any help on this would be great and much appreciated.

Navigator,

 

At 30k you need an air filter, a cabin air filter, an oil/filter change (if you're on a 7500 mile interval) and a brake fluid flush. The rest is basically an overall vehicle inspection which you can do yourself.

 

At 30k, I also changed out the factory gear lube in the front & rear differentials and put in a 75w-90 synthetic. Again that's pretty easy to do with the right socket attachments (a square 13 mm bit got the rear plugs and a "T-70" Torx for the front diff - refill is through the breather tube opening.) These socket wrench fittings are available through site vendors. I found the special 13 mm, square drive works much better than simply using a smaller 1/2" square drive (1 inch = 25.4 mm). The factory installed plugs are very tight - you may need a two foot, breaker bar to loosen them.

Have you checked the oil level at all since you bought the car?

Took my '13 2.5i Limited to get the first oil change at 3k and my mpg average for the current tank is suddenly 3MPG more awesome!

 

 

Once I get one of these, aerodynamic enhancers, I expect to get another 3MPG, mb even 4.
