Dude, the only entity that says that Amsoil outperforms all of its competition is Amsoil and those who hawk their products. Please, before you start with the usual Amsoil rhetoric, bilge we've heard here on this board time and time again, go over to the BITOG web site and get yourself schooled by browsing through the UOA databases. In there you will see a huge body of evidence that shows that in the real world, Amsoil performs no better than any of the full Synthetic (i.e. Group IV, PAO based) oils currently on the market, and in many cases worse. FWIW, even though Amsoil seems to be a fairly decent product (although very much overprices compared to the competition), due to the deceptive marketing tactics and blatant falsehoods that they use to sway the uninformed, I will not use their products and I will not recommend them to anybody else. The simple truth is that many of us abhor the noise that comes out of the Amsoil camp, and more than anything else, I believe that is what holds them back from becoming a truly successful company. Best Regards, Shipo |

Replying to: sandman46 (Dec 06, 2007 5:30 pm) I have been hearing some real good things about their EA bypass oil filter product, but bypass oil filter products usually appeal to a very very very limited market/audience. Also this product is VERY pricey (if there is such a word) WalMart's (current) $23 for a Mobil One 5w20 (can be used in your Civic if I remember correctly) 5qt jug/4.60 per qt is a metric I would consider if you are even remotely considering a like Amsoil product. I bought my last two containers in tax free OR. 2 containers should easily last me 20,000 miles x 2 for 40,000 miles.  Might need a timing belt and water pump change at that point.

Replying to: wjose (Dec 16, 2007 1:56 am) As a fast answer, I would use Mobil One 0w40 and oem, Mann or Mahle oil filters. https://www.mobiloil.com/USA-English/MotorOil/Oils/Mobil_1_0W-40.aspx You might also review the technical data updates for the latest recommendations for oil specifications. Rest assured however the Mobil One0w40 meets and exceeds the ..."VW 502.00/505.00/503.01"...specifications in force at the time. The latest specifications are the VW 507.... which (selectively) are backwards compatible. |

Replying to: ruking1 (Nov 13, 2007 8:26 am) I have made the switch to a 0W-20 Group IV product for my 5W-20 spec 07 Sonata. Its only been about 600 miles and 2 tanks of gas but I have noticed between a .5 and 1 mpg gain but its too early to credit the oil for a gain yet. After about 5,000 miles I will have a good dataset to say if the switch from a dino 5W-20 to a Group IV 0W-20 will pay off for me with better economy along with the longer OCI to truely cover the cost increase. As for the Amsoil zelots the true gains in using the product is the longer OCI the oil is built to support, if you stay with under 5,000 or even 7,500 mile OCI's then the extra cost does not justify its use. If you can run the 25,000 miles for the ASL or even the 35,000 miles of the SSO oils then yes I would say Amsoil "outperforms" the other oils

Replying to: robert1955 (Dec 21, 2007 10:41 am) It is pushing 60,000 miles at the so called elevated mpg. It was my intention to run the full OEM recommended OCI interval (10,000 miles) as per Honda recommendation, AND to switch and STAY with Mobil One 0w20 to 5w20 (group IV). So in that sense, it was NOT/never an A/B experiment. However, there is NO doubt in my mind that I would LOSE (avg over another 10,000 miles OCI) mpg, upon switch back to a conventional 5w20. Additionally passed the meager warranty period I run 20,000 miles OCI's. Again for the additional 10,000 miles, same/same (watching paint dry here comes to mind) mpg. i.e., no change. |

Replying to: shipo (Dec 21, 2007 11:39 am) Baring the doubling is understanding the modifying variables. So almost a sub variable but might be considered a main variable: 1. a percentage increase due to the greater "sump" with the addition of a bypass oil SYSTEM 2. use of a bypass oil filter. 3. Refreshment is NORMAL but "refreshment" for any condition indeed alters dilution rates, etc. Again, not a BAD thing. So indeed at BEST the documentation is sloppy. With no response to inquires, I would concur with your assessment. |
