Default Oil Question

I was at a NASA event this last weekend, speaking to a fellow Subaru owner, and he recommended Eneos 0W-50. I can't find too much on the net. Does anyone know anything good or bad about it?

a. Post in the right forum.
b. Even if you run pure synthetic blessed by the Pope, Dali Lama, Petter Sollberg, and Terrel Owens, it will not provide one iota of protection over the cheapest, most haggard oil that you can find in the seediest gas station.
c. We have an FAQ in the right forum that would have assisted you. We have FAQs so that people don't clog the forums for the other 136,000 forum users. Next time, post in the right forum or the Newbies & FAQ forum as I'll move this to the correct forum now.

I find it hard to believe that is the case. Thanks for moving me to the correct location. Enjoy sidesteping your clutch.

Funny stuff.

I wonder though, if Terrell Owens endorsed some oil it would at the least be very slippery...like butter.

Unless you are a tribologist my outlandish statement is pretty much true.

Well I'm no tribologist, but there are differences in oils.
Run Mobil1 5W30 (or any energy conserving SM 30 weight) and German Castrol 0W30 in AZ the summer in a 2.5 turbo for 6,000 miles and have a used oil analysis performed. The used GC will probably have a higher viscosity than the M1.

Although using the proper viscosity of any oil for your conditions is probably more important than brand.
Eneos is Japanese. A little info on BITOG.

There are differences in oils, but is there REALLY enough difference for us to get all wrapped up about. Aside from being all oil geeky and learning about oils as an interested hobbyist (reformed oil dork myself, so no offense meant), would using say Mobil Delvac vs. Ghetto superstar API certified no name oil for 89 cents/qt in accordance with the manufacturer's suggested intervals mean any difference in terms of:

Power
Engine Longevity
Vehicle Resale Value

Now I'm not hating, but when you get down to brass tacks, we have to be honest here. And I'm not proclaiming to be a tribologist or subject matter expert, just someone who has researched a lot and found no supporting evidence of "better oils" being better. Here's what Consumer Reports said about crappy oils doing just as good a better oils though:

"None of the tested oils proved better than the others in our tests. There may be small differences that our tests didn't reveal, but unless you typically drive under more severe conditions than a New York cab does, you won't go wrong if you shop strictly by price or availability. Buy the viscosity grade recommended in your owner's manual, and look for the starburst emblem. Even the expensive synthetics (typically, $3 or $4 a quart) worked no better than conventional motor oils in our taxi tests, but they're worth considering for extreme driving conditions high ambient temperatures and high engine load or very cold temperatures."

I guess this is partly my fault. This was in reference to racing and also living in the desert (i.e. Tucson) I should have mention it in the first post. I understand for 98% of the Subaru owners out there, the most basic synthetic will be more than enough. My question was more for the other 2% out there. Thanks for all the answers. I'll continue to look for more info on a racing/DD oil living where I do.

I agree that under suggested manufacturer drain intervals any oil is fine. But try doing extended drain intervals with 89cent a quart oil and see what happens

I'm willing to bet that a fair number of Suby owners fall into the following categories:
1. People who bought their car for the AWD. Specifically for snowy/icy conditions. (Low temperatures)
2. People who enjoy spirited driving and/or motorsports. (High-stress)

Just based on the article, synthetics do provide better protection under these circumstances.

Is synthetic worth the money? Is the extra protection gonna be visible during the car's life?
Who knows. Consumer Reports mostly targets the mundane (typical) audience. I doubt we'll ever see them test oil for more spirited drivers. (Not to mention, they usually don't test cars that cost more than $50k)

I'd agree there are always flaws, but I'd say that NOBODY puts as much stress on their engine as a NYC cab. VERY interesting article I think and it's the closest thing there has ever been to real testing of oil and probably will be forever.

I went to the Valvoline web site and asked "which oil to buy" for my 01 outback and they recommended that I stay with the Dino oil because the weather around Michigan and Ontario does not fall into the extremes of hot and cold weather, along with not towing a trailer...and that I stay within the manuf. oil change schedule... .
