I was just wondering if the oil/oil filter companies read BITOG as well as other sites. BITOG is the best site that I have come across thus far and I think that it could help to keep the oil companies on their toes, (that we are watching them). Look at what we have all learned as-far-as, which oils/filters could be better than others. Which oils/filters are just simply over priced, or the bargan of their type. We've all seen for example, the difference between SL GF-3 and SM GF-4, especially in the lower ZINC/higher MOLY levels and also, just how robust that most of the 5W20 oils are. And we have also seen some oils like Mobil 1 using a weaker addative package in some grades, and Valvoline All Climate starting to add MOLY. What do you all think ???
