Oil analysis on German Castrol Syntec 0W30, 5,930 miles, FXT
Report by Blackstone. First column is current, second column is M1 5W30 w/5,774 miles on the oil.

I'm guessing that fuel dilution is due to the fact that it was winter and I drive five miles each way weekdays. I probably didn't "push it" as often as I would've liked [no track, strip or auto-x]. It looks like the additives and viscosity held up "ok" despite the dilution. No make-up oil added, although it was about 1/2 quart low right before I sampled it. The M1's viscosity by comparison was 57.8 during the summer on less miles and .5% fuel dilution. Not sure what I'll try next. -Dennis Last edited by bluesubie; 03-24-2005 at 08:52 AM. |

My dealer is pretty level headed when it comes to things like that though. If it ever came down to it, I can now prove that GC protects better than M1 even though it's a 0W30. Quote:

I would like to have an analysis of my oil to see how its doing so I can know for sure and not speculate on how I 'think' my oil is. |

How much is the GC? The way they rave about it over at BITOG it's like the holy grail of lubrication...shoot, it even has its own category in their forums. I wonder why it's not classified as being "energy conserving?"
I'm very content with M1 although I returned all my cases in exchange for 10W-30. |

I bought it on sale for $3.99, IIRC. It's too thick at operating temp. to be energy conserving. It's around 12.2 cst's while most 30 weight synthetics are 10-11 cst's. Thicker oil = better protection, but slightly less mpg's (what, 1-2 mpg's?). -Dennis |

With those 5mi short trips and cold weather, good to use around a 5k oil change interval. I'm running 7.5k intervals but my commute is 22mi in SoCal, so I could probably bump it up closer to 10k. Any synthetic oil will work well in Subies. I've tried M1 and Amsoil in various weights (0w30, 5w30 and 10w30), with similar readings on all of them. My best numbers were my last on M1 10w30, but the numbers just seem to keep on getting better with time. My last UOA is here: http://www.greenhydrant.com/gallery/.../c35071?full=1 |
