speaking of mobil 1 adding phosphorus to their oil as an additive (playing catch up with amsoil) when amsoils already does this, I found something interesting....

Valvoline synthetic actually has more phosphorus than amsoil does....so then, I would think the amsoil dealers on this site would want to switch to valvoline synthetic?????????

Just a thought...

 

To the best of my knowledge, Mobil has used Phosphorus in their Tri-Synthetic for quite some time now. Supersyn has 5% more Phosphorus than Tri-Synthetic. The difference between Mobil 1 and Amsoil has been the amount of Phosphorus used. Currently Amsoil's 5W-30 has 47% more Phosphorus than Mobil 1 SuperSyn 5W-30.

Regarding your comments about Valvoline, Phosphorus is hardly the only indicator of a good oil, but since you brought it up again: Valvoline Synpower 5W-30 contains 1158ppm of Phosphorus. Amsoil 5W-30 contains 1259ppm and the 0W-30 1248 ppm. Using first grade math both of those numbers are higher than Valvoline.

In another post you recently made you mentioned "Amsoil had the highest levels of zinc in an oil spectrometry test independentally completed on 09.04.02". Where did you find this??

 

Man this thread was open back when I had just started browsing the board. I was just going to comment on the MB oil life monitoring system. That was actually developed by GM (AC Delco I think) and features prominently in several of their later models (My grandparents have a 2000 Buick with the system). It uses conductivity to measure the amount of metal particles and crap that are inside the oil and then determines when it is time to change it. It actually has an oil life output in most models, telling you percentage wise how much of your oil life you have "used up". Pretty cool technology something GM comes up with lots of.

 

hey mdv,

I'll get the thread for you.....

It shows Valvoline with a higher lever than the amsoils.....

I'm not saying the amsoil is not better than valvoline, just that the chemistries are very similar....actually, I would like to try amsoil for myself....

I get you the web address....

I was curious because there is a spreadsheet compiled by a moderator at maxima.org with lots of baseline samples and used analysis reports. It's also the one I use on my own website. It may be a coincidence, but it was last updated on Sept. 4th. It doesn't show similar chemistry's between Valvoline and Amsoil though.

 

It is pretty cool. BMW also has had a system like that for some time. I think they monitor the number of starts, engine rpm and coolant temperature to come up with their numbers. They use a countdown mileage interval display. It's kinda interesting to watch the interval stay steady for a while when cruising down the highway.

The biggest drawback with these systems is that they can't figure out what type of oil is in there, they're calibrated for whatever the automaker recommends.

 

Well crap in the oil is pretty much crap in the oil. Although if you were wanting to extend past the manufacturer's recommendations (and it were one of the countdown type, Honda even sells cars with those now) it would be annoying to have a light or display telling you to take your car in for maintenance when you weren't ready to. My understanding is that the GM system will work with any type of oil.
