Well, you could run the MI Extended Synthetic 5w-20 which I believe has slightly higher viscosity numbers towards the high end of the 20w range. Just a thought. Not implying you change it at a longer interval.....just for the viscosity and extra additives perhaps.

I bought up a lot (26 quarts) of the M1 0w-20 SL when I heard they were going to discontinue it about 2 years ago and now I've read here that they have come out with a SM version of the oil. What are the major differences between the two regarding additive packages and is the new 0w-20 a PAO...

Yeah, I've heard a lot of folks like and so well on the Rotella and even their 5w-40 syn. I just like the 4T M1 anf it runs well in my bikes. I think we're both crazy on running out bikes...lol. A friend with a HD Nightrain was trying to outrun me on the Busa in FL on a 4 lane rurual highway...

I like the M1 racing 4T for all the reasons you mention. I also use it in my '06 Kawasaki Vulcan. Same situation as the car. The don't put on many miles during the riding season. The Busa runs hot (and fast...lol) and the extra $$ for the 4T to me is not a significant issue since I am only...

I changed out the initial oil at 1200 miles to get ride of any engine debrie and wanted to run the M1 0w-20 after break-in. I also use about 4 oz of Schaffer's Moly EP oil treament for hte antimony and a little extra moly (also recommended from thi site when I used to participate in the past)...

I used to visit this site a lot but haven't in about 2 years. I have an '07 Acura TL-S and changed out the factory fill after 1200 miles to M1 0w-20 (I bought a lot of it up before they went to 5w-20 based on the good results I saw posted here). I don't drive too much. The current M1 0w-20...

This is suprising to me. The ASL 5w-30 and ATM 10w-30 are basically the same oil (except for low temp properties) and both have low NOAK and 11.9 cst at 100 degrees. What would account for the better results? Is the stability of the ATM that much better than the ASL?

I've noticed that Amsoil's oils have a lot of Mg in them compared to other synthetics. I would guess this is to aid in extended drain capabilities(?). Is there any downside to an oil having over 500ppm Mg in its formulation?

If we assume this batch did indeed have 9ppm of iron to begin with and extrapolate out the numbers to the recent G35 UOAs with M1 and Amsoil 0w-30 with LC, GC appears to be a very good alternative as is. Interesting as GC has no boron or moly and similar other additives but is A3 rated. It does...

All very interesting. You do have to give M1 credit for taking the high road. They could have simply gone the i.e., lower cost Grp III route in the blend like many other oil companies. Instead, they pushed the technology to maintain a true and arguably better synthetic while lowering their own...

Given what we now think comprises M1, is this a 'better' formulation than someting like Amsoil that still uses PAO/POE? I know the M1 is more economical for them but is it a step 'back' from a PAO/POE blend like perhaps their Delvac. It appears to do well enough in the UOAs but then so do a lot...

In the above post, I meant to say Group II+ but in any event, I understand they have to use something like an additive ester or Group I/II dino to carry the additive package in suspension. But how do they accomplish general solvency and/or thermal stability. The paper says ANs have good solvency...

Does this indeed mean that SuperSyn M1 does substitute an advanced AN for POE? If so, how does M1 accomplish any solvency for the additives and thermal stability that Molacule talks about(sure would explain the lowering of flash points and increase in pour points from Tri Syn to SuperSyn in the...

Is it possible that George CLS' statement last year that M1 SuperSyn does not contain esters implies the new formula is a PAO-Advanced AN formulation? Just a thought. Also, give the information provided by Mola, it would seem ARX would like a high milege dino that has some esters in it rather...

They should last 200k miles+ with no problem unless there is something inherently bad with the coil paks to begin with. For example, Nissan's with coil paks in the '99-01 timeframe have a known problem with the coil paks and they can intermittently fail without setting off the SES light causing...

Just out of curiosity, do any labs offer better or statistically tigher analyses for say $30 or $40? I'm sure better analysis means exist for big bucks but is there something 'better' in the under $40 range?

Well, I have disagreed with waiting until over 10k miles to change to synthetic with the Nissan VQ engine and will do so again. Since I began using synthetics in the early '90s, I have had about 8 Nissans with the VD or VQ engines including my current 2k3 Max which had the same engine as the...

Thank-you. I was not trying to assert that higher viscosity oils were better, categorically, than lower viscosity oils. I was only putting this on the table for discussion as the the reverse proposition, as advanced by this author, seems just as invalid. As I have said many times before, I am...

The following link is to a Blackstone Labs Newsletter. The author at Backstone asserts there is no correlation in wear and viscostiy. He asserts that wear is a function of keeping the oil clean (and I would guess changed often). What do you think? Based on the UOAs done by them and posted here...
