Thats quite an impressive report there cause a lot of us have valve train noise. I am going to have to check that out. Do you run the same oil in Winter and Summer? Thanks, Scott

Here is some info on it. Its 8.75 a bottle on ebay.

Provides the quickest starts and fastest oil pressure rise. Will reduce turbo lag and provides more power and best economy in an engine in good condition. Replacement for OE factory-fill oils in passenger cars and most light trucks, including most new GM cars and trucks. Thicker oil film at operating temperature than a petroleum 10W-40. Best choice for engines operated in extreme cold weather.

Red Line’s synthetic motor oils are designed to provide the highest protection, cleanliness and superior drain intervals with the lowest friction for your gasoline, diesel, motorcycle or marine engine. We use the most stable components available and formulate our products for wear protection and friction reduction across a wide range of engine operating conditions. Red Line's products are unique because they contain polyol ester base stocks, the only lubricants which can withstand the tremendous heat of modern jet engines. These synthetics have a natural multigrade property which allows our chemists to avoid bulking up an oil with unnecessary additive packages.
