Nope. No way. I have had great results over the last few years with full synthetics that are about 75% Group III and 25% Group IV. Very reasonable pricing and stellar results. And as the article stated, this is all going to change, and has already started. Shell is really cranking up it's Gas To Liquid (GTL) production, and if you take the time to look on shelves at the stores, virtually all of Shell's synthetics are natural gas to liquid products that, according to the article, are considered "super" Group III synthetics. We have so many excellent choices that advanced technology is giving us. Wish we had the quality of oils we have today back in the 60's and 70's.
