I took my EG to Bumpus for service and asked about the 5th gear noise. Their answer confused me. The manual (yes I did read it as I plan on keeping it forever and driving it until the wheels fall off) states that the shift points are: 1st 15 2nd 25 3rd 30 4th 40 5th 48 6th 55 Which is about 2000 RPM. The dealer said that the manual was wrong and I should not even go into 6th untill I hit 75-80 MPH. Is this right?? Not any speed limits that fast around here. What speeds is the correct speeds to shift at for fuel economy and still not lug the engine? Thanks.
