YES! This product does exist. As a matter of fact, I have 12 quarts of Havoline Synthetic 0W20 sitting in my garage.
In December, I wrote a short letter to the CEO of Chevron, expressing my frustration in finding this product anywhere in Michigan - on the retail level. In the letter, I stated, I was a long time Havoline user, who was about to go over to the "Dark Side" and use ExxonMobil products because of their widespread availability - and lack of Chevron availability.
For my efforts, they sent me the 12 quarts for free! I too, was interested in finding this product because it is (I believe), the thinnest 0W20 on the market. [8.0 cst@100C & 41 cst@40C]. Just want you want, for maximum fuel economy purposes when gas prices hit $5/gallon this summer. I haven't used any of it yet. I plan on putting it in a Ford Focus.
There is the possibility you can find this product at your local Chevron Distributor. However, I am the kind of guy who likes to see and feel the bottle at the retail level, before I buy.Bottom line, if there is a product you can't find in your area, complain to the top boss - in writing.
