He says there is a new issue with silicon - the problem with that comment is that silicon is not significantly higher than it has been on all the prior samples. The other significant point is that I recently sold the truck. The buyer had the truck inspected, including a visual examination of...

The custom intake hosing tends to let the worm clamps work loose over time, which I believe lets in a little dirt, but I've been watching that pretty closely over the past year, so I was expecting the silicon to be a little better than it was. I believe that the 0W30 is a little better...

Here is the latest oil analaysis on the supercharged Ranger, which now has 124,500 miles. Last change I switched to M1 0W30 (previous had been M1 5W30) to see if there was any change in performance or mileage. I did see a mileage increase of between 0.5 and 1.0 mpg over the life of this oil, and...

Justin, it has a M90 from a 94 SuperCoupe. It made 251 lb-ft and 218 rwhp with an early tune and the stock (3.27") pulley. Now it has a much better tune and a 2.8" pulley, so its better :) Here are a couple of photos: John, I'm using the stock paper filter (Fram) with a modified airbox to...

deven, I am not the least bit concerned about 32 ppm of iron after 10-12k miles. (M1 always shows higher iron values, and I've never heard of anyone with a dead engine attributed to M1.) pickled, I have had M1 5W30 in this engine since 10k miles, I just switched to M1 0W30 this change. Max...

Here is the latest analysis on the supercharged Ranger. I dropped to 10k miles only because I have been driving the Ranger a little less (business is down and I've been driving one of the SHOs more), and the 6 months were up. I had located and apparently stopped a few small intake leaks, which I...

I asked Blackstone why they were complaining about the wear numbers. Here is the response: Since none of the reported wear metals are too high for 12k miles, I think I'll keep doing what I'm doing...

Its not that I'm unhappy with the wear metals counts, I'm just trying to understand the definition of "good". The s/c made a significant difference in the performance. Almost stock, the truck dyno'd 210 lb-ft, and 183 hp at the wheels, in current tune w/ blower and no charge cooling, it puts...

Yes, the latest is on the left - the system replaced all the 'tab' with 'space' so its now hard to read...

My most recent uoa shows regular old M1 5W30 staying in grade for 12k miles, despite all the bashing its taken recently... and its under $20 for 5 qts at Wally World now.

Thanks, JAG, I appreciate that insight. I realize that not all G3 base oils would be of the 'modern' current technology quality, but would I be at risk in assuming that the stuff Mobil is likely putting into M1 is the current technology quality?

Can anyone who is knowledgeable tell me if that article is on the money, or if its not, why not? I'd really appreciate the insight.

Why do you say that M1 is not as good as it used to be? I still run long oci w/ M1 and haven't observed anything to support that statement. (I'm not trying to start another flaming battle, I'm asking a serious question here...) According to this article, I might actually be better off w/ G3...

From the reading I've done, the EP results are no better (and possibly worse) than regular M1, + it costs more, so I'm really not inclined to try it. I think I'll run the regular M1 5W30 another 12k miles and see what it looks like then. I know when I put on the blower, I took care of any...
