Driven offers two products specifically tailored for Ford engines like the Coyote and Modular late model Mustang performance market with their FR50 and FR20 synthetic engine oils.  Choosing the right one for your engine will not only lubricate the internal parts better, but will contribute to longer engine life as well.  While the FR50 and FR20 engine oils are not NASCAR oils, they use similar technology to create an oil that has a lower volatility, and higher viscosity index.   Driven’s FR20 and FR50 engine oil have a lower volatility of around five-percent versus fifteen-percent for most off-the-shelf engine oils. This means they are less prone to vaporization.  “Excessive oil vapor in a high-boost racing application could be the difference between detonating and destroying an expensive engine or winning a race at the track,” says Lake Speed.  

     FR20:

   FR20 is a 5w20 oil that features a high zinc content to protect aggressive cam profiles, and the advanced synthetic formula delivers high temperature protection from viscosity breakdown.  Joe Gibbs Driven FR20 delivers enhanced film thickness as well as increased anti-wear additives.  At 300 degrees, Driven’s FR20 with a VI of 160 and a labeled viscosity of 5w20 might actually have a higher viscosity than a labeled 5w30 oil with a VI of 100, at the same temperature.  This is because the higher VI FR20 product can maintain a more stable viscosity over a broader temperature range.  For high output modular Ford engines including the Coyote, there is a need for an engine oil that is the same viscosity as what Ford recommends from the factory, but is more stable under the heavier shearing loads, and heat from modified engines.  “Unless you’re changing bearing clearances or the oiling system, you should stick with the factory recommended viscosity,” says Speed.  So in modified Coyote and modular engines, Driven’s FR20 engine oil offers the benefits of OE recommended viscosity, with better volatility and VI than an off the shelf product.  Overhead cam engines rely on those lightweight oils. Unlike a a cam-in-block engine, the camshafts are all the way at the top of the cylinder head, the last place to get oil.  This means that when the engine is cold, it’s critical for oil to reach those camshafts as quickly as possible creating the need for a lower viscosity oil.  Changing to a higher viscosity oil can potentially slow down the progress of oil reaching the cams in a timely manner. When you throw in the pressures needed to operate variable valve timing system like on Coyote powered Mustangs, having the proper viscosity is even more critical, since the engine relies on hydraulic pressure from the engine oil to operate.

      FR50:

   For high output modular engines that have had significant oiling system changes, such as to the bearing clearances or oil pump, Driven has their FR50 oil. Offering the same VI, and low volatility index benefits as the FR20 oil, FR50 is a 5w50 oil that will help looser bearing clearance engines maintain proper oil pressure.  This is especially critical for Coyote and other variable valve timing engines that rely on that pressure to operate their variable cam timing systems.
