Even the 20w-50 from these vendors have low ZDDP levels, and the 20w-50 oils have noack of
Since my 318i is specified for 20w-50 as a recommended oil, I may try it to see how consumption looks... Assuming the GTX 5w-30 I have in there is consumed fast.
Don't be shy... share what they told you.
Well valvoline was mostly useless. They post generic and vague numbers for noack, and that's all they could say.
Pennzoil confirmed that their zinc levels in their 10w-40 and 20w-50 were 800ppm.
WPP sent me full data sheets, and their zinc is 850ppm, but noack is 5.1for the 20w-50! Same zinc for the 10w-40, but noack is 13.5 for the hm and the regular. The 10w-40 hm is more viscous at 100c.
