My problems with the T-25 would not go away so I finally had to send it in to Lambert. Turned out the culpit were contaminated fuel. The fuel-needles are very thin so it`s extremely important the fuel being clean/well filtered! Lambert does not recommend diesel or 2T oil as this will clog up bearings over time. Currently I`m running Jet-A1 & 5% JetCat oil. Have worked flawlessly so far
