In development for several years, we now offer DT40, a high zinc formulation for modern European Sports Cars in a 5w40 viscosity, specifically engineered for street use superior to any oil LN Engineering has previously used or recommended and has been thoroughly tested by Flat 6 Innovations and Jake Raby, coinciding with their joint development of the M96 and M97 engine platform. Additionally, for aircooled models, we now offer DT50, a high zinc formulation for older aircooled engines in a 15w50 viscosity, again specifically tested by Aircooled Technology, another Raby Enterprises company.


Both DT40 and DT50 are 100% fully synthetic motor oils based on group 4 and group 5 base oils with a proprietary additive package developed exclusively for Joe Gibbs by Lubrizol and is not sold or marketed under any other name or brand.

  For vehicles where DT40 is used on the street, for track use Joe Gibbs only recommends use of their XP9 race oil, specifically developed to resist thinning at the higher temperatures experienced by the M96 engine and also has superior foaming and aeration control, leading to improved oil pressure on the track and less strain on the AOS. Joe Gibbs offers complete engine lubrication solution including assembly grease and break-in oils, developed to provide the best protection possible for your engine and together offers the only lubricants specifically developed and tested for this target market. Joe Gibbs BR (break-in oil) is used by Joe Gibbs Racing to break-in and dyno all their engines, this petroleum oil provides optimum levels of zinc and phosphorus for flat-tappet engines. The additive package promotes ring seal and provides maximum protection available for cams and lifters during initial break-in and does not require additional additives. Above providing the highest quality products for our engines, Joe Gibbs has invested in providing excellent technical information regarding lubricants and how their selection is critical.
