an interesting comparison of several brands
i already had this released before somewhere else, but is fit to bring it here:
at least this is made of gas. and they claim that is better this way.
there is a test that shows some interesting data: https://www.northamericanmotoring.co...g-results.html
here they do 5 different tests comparing pennzoil ultra vs mobil 1
on the 1st 1 they test for scar (the smaller is better) pennzoil: 0.45, mobil: 1.6
2nd (TBN)-the higher the better: pen: 0.95, mobil: 0.95 both the same;
3-crank-the lower the better: pen:3900, mobil;: 3900= both the same;
4-TEOST (oxid)-the lower the better: pen: 0.9; mobil: 2.5
5-NOACK (volat)- the lower the better: pen:7.1; mobil: 8.5
