#1086285 - 02/14/08 07:29 PM Mobil One's "new" 15-50 and zddp levels

I've read the chart (http://www.mobiloil.com/USA-English/MotorOil/Files/Mobil_1_Product_Guide.pdf), and I still cannot determine exactly what Mobil 1 is correct for my '91 ZR-1. The chart shows only one 15-50 and it says it has a zddp level of 1200...which is what I need for my ZR-1's LT5 engine.

I have in my hands two containers of "new" Mobil 1 15-50 oil that I've been wanting to use for my next oil change. However, the container only shows an API rating of SM, SL/CF. This alone does not indicate it would carry any more than a zddp level of 800. Though it says "...and anti-wear for performance vehicles", it does not indicate anywhere if the zddp level is more than their normal SM,SL rated oil.

It also does not say anything about "extended life" or anything to do with "extended". It doesn't say what the "extra anti-wear protection" is.

So, my question is: is this the same 15-50 oil in the chart above, or is it just a 15-50 with the same 800 zddp levels as their other oils?????????????

The caps on the P/Zn levels of API GF-4 SM grade only apply to certain weights; 5w-xx, 10w-xx, 15w-50 not being one of them.

Despite the SM grade Mobil 1 15w-50 has an honest 1200 ppm zinc level.

If you're right that's really good news for me. Is there some way for me to verify this??

you can send a sample out for a VOA, or call Mobil with your question.

Here is the Mobil oil product guide.

http://www.mobiloil.com/USA-English/MotorOil/Files/Mobil_1_Product_Guide.pdf

Independent VOA tests have also confirmed Mobil 1 15w-50 advertised specs.
Use it in good health. \:\!

I just realized that there are two pages to that guide, and that the 15-50 rates the same ZDDP levels whether it is "Extended Performance" or not.

Fantastic!

Thanks!!!!!!!!!!!!!!

My understanding is the latest silver cap 15w-50 is a slightly different formulation and superior to the previous "Extended Performance" version.
Albeit with more or less the same ZDDP levels.

there is a standard set of rules that make certain viscosities exempt from the caps.

Whether or not the OE enforces those caps voluntarily on other products can only truly be determined by UOA, but some PDS might explain their formulation to some extent too.

The 15W50 silver cap oil is awesome stuff. I`ve been using it ever since it came out (used to use the 15W50 Extended Performance. Used it for about 4 years). I use it year round and it`s the best out of the various oils I`ve tried.

If you lived closer, I got 3 cases of the old SL 'Red' cap that I would sell you cheap.

Some of your local Gold Wing riders might be interested in that 'red cap'.
I have my last four bottles for use in the fall.
