Back to topic - on the posted UOA, doesn't the viscosity scare anyone? How should that be interpretedRight off, with my meager and growing understanding of UOA and their analyses - I'd say 7K miles on a new-ish car engine is a terrible, terrible idea. Or am I exaggerating that? CrossBow, how do...

FYI - the Mazda B3000 is a Ford Ranger in disguise - so follow Ford specs for that. The 626 engines were probably not made to the same tolerances as the 6i and 6s engines, and as a result, a higher viscosity oil is recommended for those cars, than the 6's engines. We use 0W20 as a suitable...

Hmmm - that's odd. I remember Janice mentioning that non-synthetic oil was bought for this oil change, many months ago. Probably Castrol Syntec (whcih she has used before) or Mobil's non-sytnth that comes in the blue carton and blue bottles. Deeper investigation is warranted - especially...

Yeah - check all the UOAs that Mazda 6 owners (with the V6 and the I4) have posted here, as well as on mazda6tech.com. Mazda6Tech UOA link Almost all of us switched to Mobil 1 very early (0W20 to match the factory recommended 5W20) and have seen great running-in wear numbers, with steady...

Thanks! Any further comments regarding ... 1. Iron content. Does it track miles that much? Shouldn't I see it drop? (I know - its still lower than many other cars) 2. My long thesis about recovering les oil than I put in - 3rd post above ( Upon looking around the forum, slight oil consumption...

Ahh - thanks for posting that for me! Yeah - another good UOA, another wasted $20! And this was arguably the hardest driven interval yet. A lot more redlining than ever before, hard highway and city miles (my commute is mostly highway, 30 miles daily - so that's good). I did have a question...

Umm - sure. I merely meant that, in the context of the Mazda 6, "this engine" should be replaced by "these engines"

Just felt the need to add a "yay" and a quick note ... there are two Mazda (Duratech-based) engines spewing out all these awesome reports with Mobil 1 0W20 and sundry non-syn 5W20 oils - and the other one is the 4-cylinder 2.3l So the statement above should read "... nice to see so many good...

He he - I only understood the "Great report BTW" part. What language is the rest of your post in? I'm guessing you're saying the oil seems to be holding up very well in terms of properties? Newbie question alert! So is a measured viscosity in the high end of the range BETTER? Like my 58-ish...

Notwithstanding that Blackstone has already replicated the previous UOA results ... I'm still including a link to all you good folks' observations after the first UOA and previous oilchange ... http://theoildrop.server101.com/ubb/ultimatebb.php?ubb=get_topic;f=3;t=000985#000000 I'm thinking...

So ... here's my second UOA ... http://www.therealashu.com/auto/mazda6/UOA/uoa_2nd_2_23_04.pdf And in image form ... They (Blackstone) like it, in their little analysis blurb. Iron is apparently consistent with mileage, and reduced copper is a good thing. As is the reduction in silicon. I've...

Awesome! Looks like the 5W30 gets the job done as well! Everything is within tha same ranges as all those 0W20 and 5W20 UOAs with Synth! Waiting for the experts' opinions I wish more people would post analyses for their 6i's - is mine the only one for a 4-cylinder engine yet?

Mikep - I hear ya on the Mazda 6 reviews I went through the same thing, and by the time I piccked it, the ONLY cars in the running were the Mazda 6i manual (which I bought), the 6s manual (less tossable, heavier front end, less discounts, more gas usaage, less spunky engine down low) and the 6...

Wow - Greg (crossbow) told me to post here. You guys are a virtual cornucopia of information and knowledge! Yeah - on the whole I think the oil is doing good. I agree with the folks who question the advantage of under-warranty 5K OCI switch to M1. It is overkill. But I figure - can't hurt...

FYI - so that maybe someone can suggest what (better) oil filters I may be able to use, here are a few pictures ... new and used. Also, let me know if in the experts' opinions, everything appears normal (visbly - if its possible to tell? ) Filter sitting on the cartridge that comes out of the...
