Mobil 1 Oil analysis in!
Posted July 05, 2005 - 05:44 PM
The oil analysis results comparing the old Mobil 1 15w-50 synthetic (red cap) and the new Mobil 1 15w-50 Extended Performance (gold cap) show the oils to be nearly identical.
The amounts of Molybdenum in both oils are the same (82ppm) so there will be no clutch problems with the new oil. The amount of anti-wear additives (zinc and phosphorous) are virtually the same. The amount of zinc in the new oil is down a few ppm's but the phosphorus is up a few ppms.
For those of us that fell in love with the old red cap fear not, the new gold cap EP 15w-50 is the same oil.

The Mobil 1 15w-50 synthetic (red cap) has a pretty big following on TT, just check some of the polls. When Mobil discontinued that oil and introduced the Mobil 1 15w-50 Extended Performance" (gold cap) many riders were concerned that the Mobil claim of XX% increase in supersyn meant that the new oil was loaded with friction reducers, i.e. moly and it would cause clutch slippage, myself included so I spent the money and had both oils analyzed. They are basically the same oil, give or take a few ppm here and there, the moly content is the same.

Sure hope that's the MC-specific oil.
Check out the analysis of using Mobil 1 car-stuff...
WoW!!! I'm never gonna use the car stuff evar again!!!
We all know that no one has ever has a transmission failure using mc specific oil right?
That thread was an embarrassment...

I think its great that Vibeguy took the initiative to use science and find some hard facts on this as opposed to speculation. Thank Vibeguy! When it comes to oil, everybody seems to be a petrochemist these days, but the amount of mis-information out there is staggering. Like Vibeguy, I also use oil analysis for gathering data on new oils, but mostly for spotting trends and it's very good for that in addition to giving you a good idea of what additives are being used, how a specific oil and additive package is holding up for a given application, whether or not your air filter is effective for your application and or service interval, facts about certain engine components wearing out prematurely or clues to a part that's about to fail, etc. It's not all cut and dry though, especially for shared sump off road motorcycle applications and you often have to build up some history if you want to spot trends. You've got to know what you're looking at if you want the most from your analysis, which can sometimes be misleading.
