Hi Keith - great question for everyone in the US. When you click on the Hemmings link in your email, next click on one of the oil bottles, and a product description comes up. In each type of Hemmings Oil, the zinc content is 1627 parts per million, which is what our old cars need. Scroll down a bit, and it says the oils are manufactured for Hemmings by Champion Brands LLC in Clinton, Missouri. Nice - a product that isn't made in China, but I digress... The Champion Brands website is www.championbrands.com . They market the same oils under their name: Champion Classic / Muscle High Performance Motor Oil. Click on "Classic / Muscle Car Oils" near the top of their Home page, then click the tab with the same title, and their classic car oils come up. The product descriptions are identical to the Hemmings decriptions, with zinc content at 1627 PPM. On the Home page, also click the "Where to Buy" tab at the top, and then "Online Retailers", and a whole list of auto stores comes up. Some are online, but several have retail stores as well. Most US members can probably find the oil they need in their own back yards.

It runs $9 and $11.50 a quart with shipping, but I would presume they will have done their homework on its formulation.

As well, remember that Rotella is formulated for diesel engines, meaning it has a very high detergent content. While a certain amount of detergent is inherent in all modern oils the amount required for diesels is considerably more, and can act as an abrasive in gasoline engines. It's therefore not a good idea to use Rotella in our old car engines. The Joe Gibbs and other racing oils that contain zinc / ZDDP are probably best. The key is to check the product and ensure the zinc content is at least 1,600 parts per million. There was an oil in the US market for a while called Z-Alt that met that specification. However, their website is no longer working, so I don't know if the company is still in business. It was about $10/US quart as I recall. In western Canada, Boss Lubricants makes a 15-40 weight with 1,600 PPM zinc content called CAM Oil. They list stores on their website in the four western provinces, including the NAPA stores in this region. It sells for about $7.00/liter/US quart. Their website is www.camoils.com . I don't know if it can be shipped to the US, but that would likely make it too costly anyway. Spring was here and then winter came back this weekend!

One of the first things to do is an oil change. Is Rotella still the oil of preference for our old style engines?
