FWIW my 2006 Rubicon has been fed Mobil 1 10W-30 since new. It now has 140,000 miles and the engine does not use oil at all. I did replace the OPDA with a Dorman unit when the Jeep was still relatively new because it started squeaking, I think that was around 25,000 miles.

I bought my 4.0 Jeep Rubicon in summer 06. It has run Mobil 1 10W-30HM from the beginning. I now have 124,000 miles on it. No issues, no oil consumption.

What is a misprint? If you mean that the 6B is a misprint then I am not sure I would trust a company that cannot get it's label certs correct. Kind of a big mistake if that is so. I guess this is why there is an entire forum for oil discussions. If it were simple there would be no need. And...

Right here, big as Dallas ;): What it does not say is anything about moly. And then there is this, Castrol edge, which inludes Mazda on their label and is GF6: I think I will just run the Castrol Edge for my early change and go from there with the dealer changes. Since other than...

I guess Idemitsu does not agree because GF6B is clearly labeled on their bottle of 0W-20. And likely will be so on Castrol and Mobil products and the others as soon as they reprint all the labels for the next run of product bottles.

Then what is the point of the ratings and certifications if not to show a particular product meets the specifications agreed upon by the auto/engine makers? As to fuel economy, I do not see the "magic" there? If the fuel economy of one product is better than another similar product, then why is...

Yes sir, I think the same way, that being any 0W-20 (ILSAC/SN or higher) oil will achieve the required performance and (importantly) equal engine life protection. If anyone has information that shows the Mazda/Idemitsu product to be actually better performance, better engine life protection...

So, then again, does that moly content make the Mazda product better than other 0W-20 ILSAC/SN plus oils? Or is that moly content the way that Idemitsu achieves their ILSAC/SN rating as opposed to other proprietary additive packages that may be as good or better from Castrol, Mobil etc. ...

I am the fella from the other forum. I think the OP is somewhat misunderstanding me. This is what the manual says: I understand that an ILSAC approved 0W-20 oil is going to be SN or now higher. We know this to be true but it is not stated in the manual. However, this is not my question. There...
