It is 8L, about 8.5 qts. It was down about 1/3 of a quart at 12,000 mi and I was going to add a bit but never got around to it. It was still less than 1/2 quart down when when it was changed.

Since I bought so many Wix kits when they were on super sale at Amazon I decided to send this sample to both Blackstone and ALS for comparison, planning to only send to ALS from now on. The results look great and very comparable between the two which is nice to see. I would like to see fuel and...

Originally Posted By: Leonardo629 I don't get it, I have UOA results to back me up Your one shot UOA doesn't really tell you that much about how that oil works in your M3. To decide that you can run track days with it and not break something is a little sketchy at best. It might work, it might...

Originally Posted By: Coprolite Phishin, I haven't seen anyone quote >15k on an OLM. If I went with the CBS for the BMW it would go about 19,000. I've kind of settled on 15,000 as being long enough, but the last UOA showed the oil was still in fine shape.

Why would you not just use the extra .5 qt at the next oil change? What is the point of saving them?

I think it's hard for anyone to give you any good input now because everything you've done to this point has been so random. 1. You dumped perfectly good FF oil with 6.2 TBN at 3000 mi. 2. That was replaced with some frankenbrew of I'm not sure what. 3. Then you ran ST 5w20 dino for 9,118 mi...

Originally Posted By: digitalSniperX1 The trend I see is that you and I both got excellent results with Mobil 1 products. That's not what I related to you at all, so just guessing but I'm thinking your a member of the Mobil 1 fanboy club, right?

Originally Posted By: digitalSniperX1 Ok just guessing, you are member of the Mobil 1 eats engines club, right? Not sure what you're getting at, but you're guessing wrong. I just went through a lot of effort to switch my F150 to M1 with the goal of 10k OCI for it. I'm not happy with the results...

Stout isn't a word I would use to describe 5w30 that ended up a 20 weight. Between mine, the 5w20 posted today and this one I think I'm seeing a trend.

Originally Posted By: Miller88 Maybe I was overreacting to something that is normal? I've only been doing all of my own maintenance / repairs for two years. Never seen that while doing an oil change before. I don't think you can go as far as to say it's normal. It may not be disastrous but it's...

Originally Posted By: CATERHAM Nice report. Was this the SN version of M1 0W-40? This was 5 qts of SM with 4 qts of SN. There's 8.5 qts of SN in there now. I agree about the previous run, that's why I cut this one down to 15k which is probably enough anyway. I don't need to get every last mile...

Originally Posted By: dnewton3 In no way is that a bad UOA, but I really don't see anything to get excited about, performance wise. I'm with you on that, it did perfectly fine but nothing to be really excited about. In all fairness it cost about 1.6 times what I paid before so it would have to...

I ran Mobil 1 5w20 for the first time in this after using GTX 5w20 since it was new. I can't say it did a bad job, but not any better than the Castrol. Also the 100 cSt of 7.37 seems pretty low. It has M1 5w20 EP in it this time and I was planning on 9k if this one looked good. That seems...

This is the second sample that was tested for this engine. There was also a short run of Synpower 5w30 in between the two that wasn't tested since it won't be used again. The 0w40 did a great job as far as I can tell. Nickel is kind of odd but I don't know what that might indicate. Silicon was...

Originally Posted By: threeputtpar Really wish Mobil would sell 0W-40 in 1 and 5 liter containers. It would make changes on my Audi easy as it takes 6.5 liters. The half liter leftover would be used on the next change. So you actually withhold the extra 0.13 qt out of 7 when using quart...
