Re: Engine oil (for european cars)
I use Amsoil Z-Rod, 10W-30. Includes anti-corrosion additives for cars that sit for extended periods between drives as well as high zinc for flat tappet engines.
Sent from my SM-G975U1 using ZR-1 Net Registry mobile app

Re: Engine oil (for european cars)
Ok guys...
reading the mobil oil product guide i can see that the MOBIL 1 ESP FORMULA 5W30 is a good choice and we can find it easy in Italy. Have 800 phosphorus and 900 Zinc, also the price is good...Here in europe, Mobil, have different type of oil that in the USA. This is what we have for MOBIL1: https://www.mobil.it/it-IT/products/...-oils/mobil-1/ what do you think of my choice? |

 It seems Mobile 1 10W-30 being fine is debatable......phosphorus 800 and Zinc 900... I am sticking with Amsoil 10W-40 with Phosphorus 1265 ppm, Zinc 1378 ppm. I suppose it depends considerably where your RPMs are most of the time among other issues... I suppose it also depends on how the catalytic converters behave with various oil chemistry.

Unfortunately here in Italy we must choose between few mobil1 oil type. I usually use the zr1 with normal drive, never track day since 2007...Now i'm using a common 10w40 oil... So, i decide to use the mobil 1 5w30 ESP FORMULA that's available here in europe, and i want to put the "Ceramic Power Liquid" treatment. By doing this anti-friction treatment I will be protected as if I had put amsoil and it lasts 100000km |
