Disregarding price, Redline gets my vote, with Amsoil a close second.
But if you take price and convenience into consideration then yes, Mobil 1 does come out ahead.

Indeed this is excellent news! If I can find it at my Autozones here in SC, it will be going in my 300 when I change the oil next time.quote:

Just to break from the pack, I vote for Chevron Supreme Synthetic Motor Oil 5W-40.
Alex,
If you have a particular application and type of engine (gas/diesel) in mind, I can tell you the best product from each of these manufacturers for that specific application. But to talk about a best oil without getting into more specifics makes no sense. My recommendation would depend on how much oil you are burning, the number of miles on the engine, and the length of the change intervals you plan to run.
For example, if you plan on changing oil every 3000-5000 miles, I'd generally recommend Mobil 1, 5w-30 or 10w-30, unless you were seeing significant oil consumption. If you want to run 12,000-15,000 mile change intervals, then something like the Amsoil Series 2000, 0w-30 would work better. If you were looking for a 40wt oil, this new Redline 5w-40 has been putting up some very good numbers.
The question is too general to give a good answer ....

I understand the excitement about the first
PAO Castrol Syntec sold in the U.S. in a decade.
However, there has not been a single
oil analysis (used or virgin) of this oil.
So, how do we know Castrol 0W-30 will not
be a big disappointment just like Royal Purple?

All I have tried so far is 15w40 Royal Purple. So I can't say it's the best synthetic, but miles ahead of the dino Delo 15w40 I was using previously for break in. I have ran a NASA track weekend with it to 6800 rpms with no problems. And I have 450rwhp/480rwt 427ci C5R blocked Ls1 motor. Can't wait to try 15w50 mobile 1 in the future after my Royal Purple stock runs out.

I'snt the true, proven, absolute quality of a synthetic motor oil derived from the four ball wear scar test?
I just put 10w 30 Mobile 1 SS into a PT Cruiser 2.4 liter turbo and the engine seemed to have smoothed out immediately. I'll be putting that into my Dodge Stealth Base after my run of Auto RX is done and I'll see if it gives that engine a nice kick in the *** .
So far I can only comment on Mobile 1 and so far I like it. Easy to get, and when bought by the case, it's not too much. Pep Boys charges 8.99 to put in the oil if you have all the stuff.
Although I'd prefer a K and N or Amsoil Filter, I stuck in a Fram for now. Anyone know what's the best oil filter by any chance?
I feel that's just as important, if not more so. FRAM is obviously everywhere.....but if I have to order a K/N or Mobile 1, or Amsoil filter, I will.

Rebel Rouser that's funny. Just the thing for a late Friday afternoon!..s

It's true, we don't know 100% for sure, but when you look at the tests it passes, we know it has to be pretty good. Europeans don't want an oil that thins out by 2.6 cst in 2600 miles, so this oil theoretically should be shear stable. Don't forget, they use very long drain intervals there. One of the tests this oil passes is the BMW Longlife, and while I don't know for sure, I'm assuming that test means the oil will remain in grade for whatever BMWs drain interval is (15k perhaps?) And the two MB tests it passes have to count for something too. You don't see these credentials on a bottle of Royal Purple, you just see a bunch of hype (unfounded hype IMO)

Even though it's not fully synthetic, we also have to mention Schaeffer Supreme in this thread. It has proven itself to perform like a full synthetic. I'd even say that it shows better wear numbers than Mobil 1, and can handle pretty much the same length of drain interval too. And look at it's HTHS numbers, they are incredible for a blend! (better than Mobil 1s HTHS numbers)
Amsoil, Mobil 1, Redline, R/P in that order.
Specs., there is more to an oil then specs. If we based an oils ability on specs alone, Amsoil would be king. Unfortunately, it's not.
It's good that we can all state our opinions on here without fighting like other forums.
While it's simply an opinion, I will say this, no one can really prove what oils are best. It would be nice to take the UOA section and summarize the results somehow. Obviously there would be many variables to standardize numbers, but we could compare the oils with similar xmiles with xengines etc.

Oils are like socks or gloves it has got to be fitted to the engine.
Was that an independent , unbiased dodge ?
For instance VWs 1.8l T like Redline 10w-30 or 5w-40.
Honda 4 cylinders like Schaeffers 5w-30 for street, Redline 5w-30 for Racing.
Amsoil 10w-30 and Redline 10w-30 in a non turbo Volvo 2.9 inline 6 cylinder.
Molekules M1 10w-30 Brew runs well in anything !!!!!!

Does that mean if the glove don't fit, the engine will quit?
What about Honda 6 cyl?
