Mobile1 ftl. I used to use it and would consume a bunch between oil changes. I've had no issues with Castrol Syntec or Gulf full synthetic.

Asking for a best brand of oil is very subjective. That's like asking which exhaust or tires are best. You are just going to get everyone's personal opinion, not an indicator of which is best.

Castrol German 0W30 gets my vote.

What do you have to support this, other than working at an "oil change place?"

Also OP, there's more info concerning this in the Service and Maintenance subforum.

Pick whichever one doesn't burn too fast in your engine so check consumption and then pick whatever you can afford to do. Like go expensive oil, change less often or cheaper oil and change more often. Something like that.

no offense, but too many people working at a valvoline instant oil change shops or some place similar feel as though there instant mechanics because they "work" on cars everyday...changing oil isn't "working" on cars. I too worked at a similar chain type oil change shop, and by no means did that make me a certified mechanic.

I agree with this guy's assertion.

M1, despite the naysayers, gets my vote and confidence

I would be really intersted in knowing exactly where you heard, or who gave you this statistic. "Less turbo lag with Royal Purple"?! BTW, EVERYBODY is just trying to get what's best for his ride. I've never heard someone say, "Man, I just want what's bad for my ride." Sorry to flame, just trying to point out the obvious.

Check out the thread by the benevolent Unabomber

I'm using Castrol Syntec 10W-40. I used Mobil 1 5W-30 for the last 10 years (in my wrx and previous car). I switched to Castrol Syntec and the heavier weight after reading about the number of spun rod bearings people were seeing with Mobil 1 5W-30.

Lots of positive posts on German Castrol 0w30....
Lots of negative posts on M1....

Even if M1 works just as well and it's just a lot of negative hype and rumors on M1 quality, I'd rather take my chances on the GC since I've had no experience on synthetics. Why take the chance, ya know?

<- Putting in my first synthetic change with GC in a month or so.


M1 is cheaper though, especially in bulk at Costco...but oh well.

heres what redline has to say bout thier oil...
Best all-weather viscosity grade for gasoline engines in cars and light trucks that are driven on the street on a daily basis. Reduces turbo lag and provides more power and economy while providing thicker bearing oil films at operating temperature than a petroleum 10W-40. Best all-round, synthetic oil for stock or slightly modified engines in high- performance cars that are street-driven. Best choice to replace a 5W-30 or 10W-30, petroleum-based or other-brand synthetic oil if maximum durability is preferred. Acceptable for engines that are occasionally operated in extreme cold weather.

Agreed, i dont consider myself a mechanic by ANY means. However when youve changed the oil on 50+ cars a day every day for the past year you do get a feel for what oils work well in what cars.
One oil that does work very well in our subarus is german castrol. Take my opinion for what its worth.

How exactly? Do you test the oil afterwards? Gut feeling? Divine inspiration?

Well just to name a few: the oil level prior to service, the number of miles on the oil, the color of the oil when it comes out, the amount of sludge in the engine and old oil filter, and reported performance.
Not to mention UOA on bobistheoilguy.com reguaring german castrol in subarus.

hmm... Oil level I can see...assuming that any low level was the result of burn off. Miles between oil changes (miles on oil) factors into that. Color of oil....is this subjective or do you have some sort of device to guage that? I also thought that most oils turned dark to almost black fairly early on in the cycle?

Sludge in the engine...holy crap, you take the engine apart?
reported performance...huh? Car gets slower with crappy oil?
bobistheoilguy....great site, good info, but how do YOU test the oil to "get a feel"...

The color of oil should be as close to the color it was when you poured it in, a golden shade.
Sludge in the engine can be viewed from the oil cap with a flash light.
Yes, i or someone else will recommend, say German Castrol for their car, they use it, come back 3 or so months later and say yes, it did help out my performance. And cars DO get slower with crappy oil. Not specifically because of the type of oil used but moreso of the sludge that builds up in ones engine when the additives in their oil break down.
And for my "personal feel" i had used Pennzoil Platinum full synthetic, Jiffy Lubes highest quality oil, and it was breaking down and burning off by 2500 miles. I switched to the GC and have gone 4k on one oil change without any oil burn off (at least as measured on the dipstick) and so far am 2500 miles into my second oil change with GC.
On top of that i modified my car to stage 2 which produces much more heat and should burn oil quicker with no burned oil to speak of.

So like i said, take my opinion for what its worth. Im not the "be all end all oil man." I have just simply used this German Castrol with excellent results and so have many many other subaru owners. The OP asked a question on what oil he should use, i replied with my personal opinion. Thats all.

Royal purple is the best bang for the buck. Its been proven over and over just search. No, your oil should not be the same color when it comes out as when it goes in. When you start your car it sparks the plug, fuel squirts in and get burned, it burns black. There is build up process of this over time that eventually gets into your oil system and causes the oil to turn black. Also if you were to be an aggressive driver, your motor will be hotter and burn the oil or discolor it. I suggest 5w30 in winter/colder months and if you would like in the warmer months you can bump up to a 10w30. I stick with 5w30 year round though.

Dont always read what you believe. And not to be rude but its people like you that tell a customer something and you dont know what you are talking about. Thats the whole reason why i dont take my car to have anyone else work on it but me, unless its someone i know very well. A monkey could change oil in 50 cars a year and could come up with a conclusion like that. Every motor is different, some burn rich some burn lean, some get worked hard, some get driven once a week. You cant say blank oil is because because what it looks like when it comes out at the end.

Maybe, maybe not. This is very subjective. I've used M1 for awhile now, and it's just fine. The oil has been tested a few times, both with great results. I've opened the filter case after every oil change, put the filter in a vise, then checked the dry filter with a magnifying glass, and no bearing particles.
I don't know, maybe I've been lucky. But I'll stand behind better maintenance on your car, than behind better oil.

....first off, this thread really belongs in the Service & Maintenance" forum. Second, I would really suggest searching. This topic gets covered more times than it probably should. Regardless of how your oil looks, smells, feels or tastes, the only way to truly know how well it is working out for your specific application is by perfoming a UOA. Read the through the links provided. You'll likely find your answers there.

Thanks goodness for this thread. It's been at least two weeks since one was started and I was getting bored from not reading misinformation.

First of all. I'm sorry, but unless you're getting Royal Purple for $4.50-$5.50 a quart it is not the best bang for the buck IMO. There have been a few uoa's posted here on RP xW30's. One was good and in two it sheared to a 20 grade in under 3k. Some oil geeks say that's fine as long as long as your wear is low (or unless the uoa uncovers a problem with the particular car). I prefer an oil that stays in grade. I would search for uoa's but I'm tired of searching for people.

Secondly, don't just believe marketing hype. Use an oil that works well for your application. Given the track record of bugeyes, especially modified ones, I would highly recommend using a more shear stable oil than an Energy Conserving one. Hint: look for an oil with a High Temp High Shear of 3.5% or greater and/or one that meets ACEA A3 specs (Redline, RP 5W40, Syntec 0W30 [GC] or M1 10W30 High Mileage). Diesel oils that are ok for cars are good choices as well (Rotella T 5W40). Check oil companies Product Data Sheets to find this info and not just the ads.

There are so many factors that determine how an oil will perform in your car, simply mentioning brands is of no help. What mods do you have? What's your driving style? Short daily trips or long ones? How long do you plan to run the oil? Pick an oil and do a used oil analysis. Also, search in this forum and at bobistheoilguy.com for uoa's.

I changed my mind and searched for the lazy:
My uoa on GC
Redline 5W40 uoa.
RP 10W30 uoa .

As mentioned, check bobistheoilguy.com.

-Dennis

No offense but if people here are buying 20-30 thousand dollar high performance sports cars but yet wont put $7.50/qt. royal purple (best in subaru engines) then good luck with how your car performs. In my experience and i am sure in many others experience, if you do it the cheap way it will cost more in the end paying to fix all the broken stuff.
