If you go to the link, on the right hand side, there are some quick links. One of them titled "Zinc and Phosporous Levels" will take you to a chart that lists every Mobil 1 oil and has the levels listed.
Other street use oils with over 1000 PPM Zinc and Phosphorous are:
0W40 FS, 5W50 FS X2, 5W40 Formula M, 5W40 Turbo Diesel |
Vascillating between the Mobil 1 15w 50 and Valvoline VR1 10w-30 for my new 400 build. Both have high zinc/phosporus levels (M1 = 1300/1200 and VR1 = 1400/1300).
I guess it may boil down to which is more readily available (no pun intended). I suppose the Valvoline might be better for cold fall days. Both are synthetic.
