Joe Gibbs Racing Oils

LN Engineering, aside from offering many products and services for both aircooled and watercooled Porsche models, devotes considerable resources to continued research and development, and most recently, partnering with Raby Engine Development again to develop Porsche-model specific lubricants.*

For years we have tested many lubricants by various manufacturers to ensure we are offering our customers the best protection for their aircooled and watercooled engines, but now, we can offer the first oils specifically developed to meet our requirements that has been tested in our aircooled and watercooled engines! LN Engineering proudly offers the complete line of Joe Gibbs Driven lubricants and automotive fluids.

In development for several years, starting February 2012 we will 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.

So how does Joe Gibbs stand up to the competition? Look below at the results from Lubrizol on the KRL test (CEC L45-A-99), which in fact is one of the most rigorous lubricant tests possible to carry out:




1 0W-40






Viscosity @ 100C





% Difference @ 100C



Viscosity @ 40C





% Difference @ 40C













% HTHS Difference @ 150C




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. For those interested, we have a Racing Oil “101” available as well as Joe Gibb’s Lubrication Guide, both in PDF format.

*For Porsche approved lubricant we use and recommend Motul 8100 X-Cess 5w40.
