Two grades lower than the manual recommends with heavy track session don't seem like a good combination. You're basically running a 30 weight oil in your engine for the track with great results, but you went the opposite direction with the tranny oil ?

Generally the harder you drive (ie track) the higher the temp of the gearbox. Oil decreases in viscosity with temperature.

I'd be running an Ester gear oil if I was seeing track time especially with additional power going through the box. What's the Pentosin MTF2 shearing back to? It's only 7.7 cSt @ 100°C where as say Gear300 is 15.2 cSt.
The 86 race series here in NZ are trialing Motul Transoil Expert 10w40 in the box http://www.motul.com/system/product_...pdf?1290086773 Last edited by SXE10; 10-04-2013 at 12:17 AM. |
