alright boys,i know that this is a heated topic here,but i need to know some real hardcore facts not just opinions.john deere plus 50 15w-40 vs shell rotella t 15w-40 diesel motor oil.which is the most protective oil in all areas?i have a new jd 5203 tractor and want to run the best af these 2 oils.i have looked at these 2 oils websites and tried to do my own comparisions myself but am not much of a chemist so i thought that i would turn to you fellas that are extremely more knowledgable in that area than me.i didn't understand what all of the classifications meant ie cat so and so numbers,api so and so number.so please help.
not sure about either, I like amsoil. Amsoil is the only one who produces test results to the 4 ball wear scar test. I usually never go with the dealer brands.
thats just me.
I don't pretent to know all the classification standards either, however, I remembered this direct comparison to Deere Plus 50 on Rotella's site. You can decide what factual value, if any, it has...
