Default Tufoil - your experience?

Hi. I've been looking into Tufoil lately, and wondered if any of you have used it, and if so, what your experience has been with it?
-
I searched the forum for "Tufoil" and found nothing. I was pretty surprised as it seems to get glowing reviews everywhere else I look.
-
Do you use Tufoil?
If not, what else do you use and why?
Have you noticed any positive changes to your Forester using Tufoil?
How do I use it - do I just dump in the 8 ounces into where my oil would go?

Thanks!

Snake oil. Modern oils are way better than the junk in tufoil. Bottom line.. you will degrade your oil by putting this stuff in there. (probably)

The stuff is as thick as day-old gravy straight from the fridge. I wouldn't put that junk in my engine.

Wow! Two VERY strongly negative opinions on this! I had no idea. Maybe that's why I couldn't find anything when I searched for "Tufoil" on this site!
What about the products' claims for faster cranking speed under all weather conditions, better gas mileage, increased horsepower and acceleration, extended engine life?
They claim it's safe for all gas and diesel engines - what makes the Forester so special that this stuff is no good for it?
-
Has ANYONE here used it and found it to be beneficial?

There's nothing special about Foresters that makes this stuff no good. It's that Forester owners have more sense than to buy snake oil products.

I actually put the stuff in my '93 Toyota Camry back when I saw the ads in Popular Science. It never did anything bad, but I can't say it helped anything either. When you look at the stuff, and how it pours, it's not something you want your whole oil sump to be filled with because of its thickness. Oil additives in general are bogus. You're spending at least 2x per quart of some unknown substance that probably isn't as good as plain motor oil at lubricating your engine. If it were, it would already be in the oil to begin with.

Didn't know that junk was still around. I used it in my 1986 Isuzu P'up 4x4 back in the day, about 1987. Didn't do anything noticeable.

Of course, I did a massive google search before posting here. And I see many glowing reviews of the product in most places I look. Either that, or people just immediately claim it's garbage with no more info or first-hand knowledge.
-
As for the arguement that it "probably isn't as good as plain motor oil at lubricating your engine. If it were, it would already be in the oil to begin with." - that doesn't make sense to me. Many people use synthetic oils. Why? I mean, if it was that good it'd already be in the oil you're using, right? Why spend the money on prime rib - if it were that good, it'd already be in that cheap cut of steak, right? That argument makes no sense.
-
Given the lack of supporting info here within this site, I will refrain from adding anything to the oil in my Forester's engine.
-
My final question, is which is the best brand of oil (either real or synthetic) for my Forester? (It's a turbo.) Do you use a specific brand or find one works better than another?
Thanks.

It's not just the reasons above that I won't use it anymore, it's the chemical analyses of it that people have done. It's just really thick motor oil, with a little PTFE and Molybdenum as additives.

As for recommendations, you're going to hear tons of them, but I've always been a believer in synthetics for turbo engines. German Castrol 0w30 syntec is probably the only "true" synthetic you're going to find at Autozone. I don't think a true synthetic is necessary. Lots of people get great results with Shell Rotella T6 5w40. Neither of them is a 5w30, like the owners manual recommends, but IMO, those are the two "best" choices for a turbocharged subaru. Again, this is just my opinion, but it's based on lots of oil analyses and online discussions.

+1. My recommendation for a turbo is any synthetic oil that is not Energy Conserving (like the RT6 or GC). Searched bitog as adc recommended and there's a few threads there. Here's one.

There are 4,321 threads on oils here and 21,792 on BITOG.com.

Bottom line..no consensus.
Too many oil wars.

I am specifically asking people here, in MY thread, what their opinion is as to the best oil for my machine. I'm not going to search, this site or any other, for this info. I ask a question, get answers, graph the results (sorta) and come up with a decision. I do the same for restaurant recommendations, advice on what vaccumm to buy, etc. I'm just looking for opinions. Here. Now. That's it.

Again there are multi threads on this board dealing with oils for Subaru engines. Over the years I have done many oil analysis on many engines. Oils are pretty much the same.

The "Best" oils will be Group IV and V Synthetic oils..Amsoil, Syntec 0W-30, Motul Oil, and RedLine, Mobil1 DelVac, and Mobil 1 5W-30. But unless you are running the vehicle super/Super hard or going extended drain cycles any Group III synthetic..Pennzoil, QS, Supertech Syn, etc will be fine.

To verify the oil you use is working your engine you need to do an oil analysis.

Keep in mind also that the best oil for your purposes depends a lot on how you use your car. If you do lots of short trips, and don't get on the highway much, drive calmly and don't race your engine a lot, your oil needs are going to be very different from someone who goes on very long road trips in the summer, tows a boat, or drag races. The only true way to know how an oil is working for you is to have it analyzed.
