Subaru Branded Synthetic Oil vs Mobil 1 Synthetic For 2012 Forester?

First time Subaru owner here. I know that the new FB engines "require" full synthetic oil and was recently in my local Subaru dealership picking up some touch up paint and I noticed that Subaru has their own branded full synthetic motor oil. I believe it is made by Idemitsu. I asked the parts guy about it and he didn't know that much about it. I asked if they use the Subaru brand or other full synthetic for oil changes and he said it varies from dealer-to-dealer, but they also carry Mobile 1.

I use Mobil 1 exclusively, mostly because it's readily available and priced well. I would like to get some feedback to find out if the Subaru branded 0W-20 in the gold containers is a better alternative than the Mobil 1?

I know there are lots of discussions on who makes the best oil and that's not what I'm asking for. I'm just trying to determine if it would be better to go with the Subaru branded synthetic or Mobil 1 when I get my Forester serviced for oil changes since that's what the dealer carries.

I don't know what kind of experience Subaru owners have had with the Mobil 1 in the 0W-20 weight since it's been out longer than the Subaru branded synthetic?

BTW, I found this interesting video showing why 2011 Foresters and newer require full synthetic motor oil.

Thanks for any objective replies.

Niether. Kendall GT-1 Full Synthetic 0W20 usually sells for about $4.99/qt, less money than Idemitsu or Mobil 1. You can get an entire case of it for less than what a dealer charges for one oil change on the FB engine:

I found this information about the two oils:

Idemitsu GF-5/Mobil-1
SAE Grade 0W-20/0W-20
Viscosity @ 100C, cSt (ASTM D445) 8.466 /8.7
Viscosity, @ 40C, cSt* (ASTM D445) 44.77 /44.8
Viscosity Index na/173
Sulfated Ash, wt% (ASTM D874) na/0.8
Pour Point, C (ASTM D97) na/-50
Pour Point, F na/-58
Flash Point, C (ASTM D92) 200/224
Flash Point, F 392/435.2
Density @15.6 C g/ml ASTM D4052) 0.89/0.841
Zinc/Phosphorus .065 /na
TBN na/8.8

I have been using Mobil-1 in my old British cars and in my 21st century cars as well. I find it to be a reliable, excellent oil.

I think you're probably safe with either of those. My dealership (which is 2km from Subaru Canada headquarters) used Mobil-1.

Depending on your area you can often find Pennzoil, Quaker State, and Valvoline 0w20 oils for a good price.

Thanks for the feedback everyone. I'll probably stick with Mobil 1 since the dealer carries it and it's also available at Walmart and lots of other places. My dealer will be servicing my car until 35K miles since I got a great deal on the maintenance package when I bought the care, which is why I asked thoughts about the Subaru oil and Mobil 1.

I used to change the oil myself but as I get older I'm becoming less of a do-it-yourselfer because my time is worth something to me and considering it will be about only two oil changes a year for me I have to ask is it worth it to do it myself? For some it will be worth it, but for others no.

But, seeing how easy it is to change the oil on the FB engine there is a chance that I may go back to doing it myself again in the future.

On a side note, are there any issues with using/changing to different brands of synthetic oils, or is it more like splitting hairs?

Thanks again for all the feedback!

It is pretty much splitting hairs as far as changing brands. They all intermix without issue. I like to try to stay with one brand's product line consistently if possible, which I was doing until Mobil dropped Mobil Clean 5000 this past spring when the SM/GF4 spec passed into history. Think I've found my new brand to stick with now, though.

I have been using Mobil-1 in my old British cars and in my 21st century cars as well. I find it to be a reliable, excellent oil.
The Idemitsu GF-5 is not what Ive been sourcing for "subaru oil". The recent "Professional Use Only" subaru oil is API SM only NOT ILSAC GF-5 that you posted. Ive run M1 0w20. Though the average fuel mileage remained the same between m1 and the Subaru oil, the engine was smoother, quieter and peppier with the Subaru oil. Purportedly neither lube is a true synthetic. In my web research, many have posted and liked the 0w20 Valvoline and Kendal products over the M1 for performance and over the Subaru for cost concerns. My car does not burn oil excessively or make funny noises as many on here have reported, it also returns a summer FE of over 31MPG average and over 28 MPG winter with a 5M. I run the full 7500 mile OCI.

HTH :)

Considering that a 12 quart case of Kendall 0W20 can be bought online for $47 ( http://www.petroleumservicecompany.c...-ti-0w-20.html ) and the happy reports on its driveability, then if I had a 2011 or 2012 model I'd be using it to keep both my wallet and the FB engine happy. Show me another full synthetic with boron, moly, and titanium all in the additive pkg for that price.

Funny your talking about Kendall 0w-20 oil. I've had my oil changed twice at the dealer and they used Kendall both times. I figure if it's good enough for the dealer its good enough for me. I did, however, go to the parts counter and get a quart of the Subaru oil to keep in the car with me because both oil changes my forester used about 1/4 qt.

Kendall is the real deal, glad to hear of dealerships using it. Its also approved for GM Dexos1, a tough spec to meet.

If its not a licensed product I wouldnt put much faith in the performance vs the AC delco product. I've read the increased additisation level for most dexos lubes wouldnt meet ILSAC GF-5.

I am 90+% certain that Kendall, Mobil 1, Pennzoil, QS and Valvoline are Group III oils. I think its more likely that Idemitsu is a GR. IV.

If you want the very best oil, go with Motul or RedLine.

Be careful what you wish for.
