[Vwdiesel] lonjevity of 86 Jetta

[William J Toensing]

B & R Decker, thank you for your reply. Haven't driven my Dasher diesel wagon since repairs due to snafu with insurance proof & DMV which should be resolved by end of week. I plan to run it on biodiesel. You have a 5 speed Quantum 5 speed. Mine has the stock 4 speed. Also, your engine has some modifications. Did they help for improved MPG? Is the top end gear ratio the same for your 5 speed & my 4 speed? Mine hasn't been modified. Should I expect the same MPG as you. I have Amsoil synthetic engine oil in the engine & synthetic Amsoil gear lube in the transaxle. 50+ USA-MPG sounds pretty impressive, especially for a 26 year old car.
