RE: homepage article on oil additives
Are we talking about fuel additives or oil additives? I think fuel additives are essential. I feel that they more than pay for themselves through better mileage and better performance.
As for oil additives, however, I am probably in the minority, but I do not think that oil additives should generally be used. Why? For the same reason that you shouldn't mix prescription medications on your own--i.e., the effect of certain combinations is hard to predict. Today's oils are carefully balanced cocktails of lubricants, detergents and other additives. In my view, if Lucas really caused Rotella to perform significantly better, wouldn't Shell sell Rotella pre-blended with whatever is in Lucas and sell the Rotella for a higher price? The problem the folks over at bobistheoilguy.com demonstrated with Lucas in particular is that it doesn't interact well with the anti-foaming additives in the base oil, and you get foaming in the oil treated with Lucas.
I'm not saying that oil additives are necessarily bad, I'm just saying that people get into this mindset that they are ALWAYS doing their equipment a favor by using additives, and I don't think that is true. That is, however, only MY opinion. There are many different perspectives on this matter, and I say do whatever you think works for you, but make sure that what is working is something more than an oil additive's advertising.
I recently switched over to Schaeffers 15w-40 synthetic blend after running Rotella with additives and Rotella alone and I am very happy with the Schaeffers. There are other great premium oils out there (Amsoil, Royal Purple), but my conclusion after reading and reading and reading is that the Schaeffers 15w-40 (with no additional additives) combined with the Filtration Solutions bypass filter system on my CAT 3126 is going to give me the best overall results.
I do not sell Schaeffers, by the way.
