schwinn Posted August 27, 2009 Share Posted August 27, 2009 In my experience, M1 isn't bad... it's just more expensive than others. For example, many people recommend Rotella T synthetic as a better oil. My UOAs (posted around here on the site) have shown that the Rotella seems to be performing just like M1 on the motor, so as far as I can tell, there is no difference. Of course, Rotella is cheaper, so I'm sticking with that at the moment... Link to comment Share on other sites More sharing options...
fishbone Posted August 27, 2009 Share Posted August 27, 2009 No, M1 isn't bad, it's just that there's been UOAs on 5w30 that didn't look that good. Something to consider when cheaper oil perform better. That being said, the Extended Performance line works great, so does the European Formula 0w40 (or 5w40, whichever). The question is, is it worth the money? In my experience, that's a fat no. Link to comment Share on other sites More sharing options...
ShrinerMonkey Posted August 27, 2009 Share Posted August 27, 2009 As I and others have said before... M1 is not a bad oil, just over-rated and over-priced. It was great for my old VW 1.8T because it was cheaper and easier to obtain than the other VW 502.01 spec oils. Link to comment Share on other sites More sharing options...
Mernt Posted August 27, 2009 Share Posted August 27, 2009 Mobil 1 is ExxonMobil's flagship product. It will always be among the best oils on the market. Oils change all the time. Currently, Pennzoil Platinum is the standout oil to beat. Mobil 1 is found in so many high end cars, and is tested over and over again. It's always a safe bet. I like their 5w40 and 0w40 oils. Both are great for Subs. Link to comment Share on other sites More sharing options...

fishbone Posted August 28, 2009 Share Posted August 28, 2009 How would you say Amsoil compares with German Castroil??? To clarify for the other members. rao is referring to Castroil which is the compressed name for German Castor Oil. It is a new branch of Castrol which makes oil out of renewable and biodegradable sources. In this case, castor beans. Link to comment Share on other sites More sharing options...

As for PP, no doubt, it's very good oil as well... Rotella is just a few bucks cheaper for me, and easier to find... unusually enough.

PP can be obtained at Walmart. It's a no brainer. PP is the more cost effective choice. Read down a bit. It's not that it's holding it's own, it's that both oils are equally effective in an easy-engine being frequently driven for a reasonable duration (7.5k miles). AMSOIL SSO is the oil of choice for someone who wants a long-drain in just about any street-driven car. But it's freaking expensive for anyone NOT running long drains.

fishbone Posted August 28, 2009 Share Posted August 28, 2009 Mobil 1 5w40 European Formula held up just fine over a 12K OCI in a Mini Cooper S. It's on BITOG, too lazy to search. The recommended OCI by the on-board system on the MCS usually indicates 12-16K miles. Link to comment Share on other sites More sharing options...
Skidder Posted August 28, 2009 Share Posted August 28, 2009 Mobile 1 0w-40 euro blend I would have to imagine is a much better oil than the energy conserving (thin as water) 5w-30... But I have no proof just research and speculation. I wouldn't dream of putting M1 5w-30 in my last car after all I had read on the WRX rod bearing issues. I ran cheap as hell 5w30 in winter with 10w-40 in summer. I plan on using the same plan for my LGT until I see proof to do otherwise... but my .02 is not worth much Link to comment Share on other sites More sharing options...
fishbone Posted August 28, 2009 Share Posted August 28, 2009 If you look at the specs, 0w40 is significantly thicker than 5w30. If PP doesn't hold up as I expect it will, I will be switching my Mini to M1 0w40. Link to comment Share on other sites More sharing options...

schwinn Posted August 30, 2009 Share Posted August 30, 2009 Damn, that's a nice UOA... my <6k OCIs aren't showing up that well with M1 or Rotella at the moment (though it might be due to high silicon, which doesn't seem to be going away yet)... I might consider trying Amsoil at some point, and seeing if it holds up for me as well. Are you using any special oil filter setup? Those are some REALLY low numbers. What about how you drive the vehicle? Hard, gentle, etc? Link to comment Share on other sites More sharing options...

That OA's was using Amsoil oil filter EaO-20. https://www.amsoil.com/storefront/eao.aspx At 73k, dual By-Pass Filter. I haven't done any OA's sense I went dual filtration. Because the OA's was very good with the small signal filter. I didn't see the need with a 2 micron filtration system, + add 2qts. to your oil system. In case you don't know, Amsoil recommended OCI's is only to be used.

JoeFromPA Posted August 31, 2009 Share Posted August 31, 2009 Schwinn - Bear in mind he's using a different lab. It's the equivalent of comparing Dyson to Blackstone. Dyson makes things look much worse, but it's just because he sees alot more crap in your oil. Oil Analyzers should only be compared to Oil Analyzers, Blackstone to Blackstone, etc. Not saying his results aren't fantastic though. Link to comment Share on other sites More sharing options...
fishbone Posted August 31, 2009 Share Posted August 31, 2009 After numerous UOAs on our turbo Boxers, modded or not, I think the trend is towards thicker oils and those that fight fuel dillution well. Someone correct me if I'm wrong, but that's what I'm seeing. Take M1 5w30 syn. It's your average 30-weight oil that does not perform good when fuel dillution is there, which our Boxers seem to be prone to. The oil shears, the additive package doesn't do as good of a job and in turn the engines registers higher than average wear. Link to comment Share on other sites More sharing options...

Still, with such good long term results, I may consider trying out Amsoil (filter alone, and then with their oil)... since I'm an engineer and always want to test things out carefully, haha!
