On this board it appears everyone agrees that Amsoil, Mobil 1, and Redline are the best synthetic oil.
But, what's your opinion(s) on the "other" synthetics?

Honestly, we haven't seen too many UOAs on the other synthetics, but the ones that we have seen don't look super impressive either.quote:

It's certainly possible. We know it's possible to make a great oil with a petroleum base stock but a great additive package (such as Schaeffer's mineral oil) but most oil companies choose not to do so. From what we've seen on most group 3 synthetics out there, they cannot go the distance like the better oils, their TBN drops too fast, indicating a weaker/less quality add pack.quote:

Patman do you think that if the other companys screw the consumers by calling groupIII syn they do the same with the additive package?
I'm pretty sure this is incorrect. BMW's 5w30 is probably re-bottled Castrol TXT, and is produced in Europe. It's a Group III/Group V blend.quote:

Then all BMW owners are screwed because BMW's 5-30 Synth. which is only SJ, but ACEA A3 rated is made by Castrol N.A. and most likely a Group III scheduled to go 10k mi...(16k km).
Well, if it says that on the bottle, I'm obviously wrong.quote:

Well, I'll say if it is it doesn't say anything about being made in Germany or whatever. Says "made exclusively by Castrol N.A. (NJ) for BMW" right on the bottle.
I switched from Mobil 1 to Synpower 5w-40 and noticed better turbo spooling too. Plus, the car runs quieter. I don't know if switching from a PAO to a Group III is a wise choice or not, but the car sure runs smoother and it was consuming that Mobil 1 pretty rapidly. I do 5k intervals so TBN retention is not a big deal to me.quote:

Having my first run with Motul 6100 5W40 and highly impressed. Hasn't used a drop so far (couldn't say that with M1 0W40 TS) and turbo seems to spool very quickly, in fact catching me off guard a few times. Still distributor here tells me 6100 is replaced by better 8100 X-cess 5W40. Motul pioneered many oil technologies (1971 1st 100% syn ester oil, 1966 first semi-syn, and 93 World Champ oil in 500cc Grand Prix, Superbike, 125 & 250cc Motorcross). Can't be too shabby IMO.
Dr. T, what UOA's have you been reading? If anything, Mobil 1 has proven to be one of the best oils, period. Go back through every UOA and you will see numbers that are great, and numbers that are not, just like any other oil. Amsoil and Redline, regardless of there specs. on paper have not shown to be better then M1. M1 is very consistant. It all depends what engine and driving style too. Mobil is limited in what they can make for $5, but for that amount, only Schaeffer's is as good. If any one oil is not cracked up to what it is suposed to be it HAS TO BE Amsoil! There are oils though that are better in certain engines for certain cars so in essence, yes, there are other great alternatives.quote:
That goes with what I've discoved too: That M-1 isn't all that it's cracked up to be
Thats fine, but are you saying it's not great in your case or you think generally it's not a great oil? I'm not partial to any one brand, but I see too many people ripping M1 when I think from what the UOA's have told us, it has proven to be a great oil.quote:
it's good, but not great
Sorry but Quaker state doesn't compare to M1.quote:
Good question. I'll say both. Primarily with my application. Secondly, if you take a look at OTC Q.S. 10-30 for eg, it is A3 rated...something M-1 10-30 can't claim...(if we're going by the numbers that is...)
Amen to that. People talk about the Xw30 grades of Mobil 1 not being A3 as if this is some sort of defect in the oil. Folks, Mobil didn't DESIGN these oils to be A3 oils. They are A5 oils, meant to meet the low friction and fuel efficiency requirements of that spec. From a performance standpoint, the ONLY difference between A3 and A5 is the HT/HS numbers.quote:
