10% Mileage increase... free...

[repenttokyo]

Power steering at near crawling speed is a wrestle... Even at 15 MPH is hard and I don't think any girls can handle that much wrestling. I think in the older days, they make the gearbox much more mechanically advantage to the driver so it is not so hard as the modern steering box without power steering.

Same goes for the brake... I think the older car's brake booster is much much bigger too.

you are right.

cars without power steering have radically different steering gears than those with. When your power steering fails, you are fighting against the power mechanism. It's not at all analogous to manual steering. My mid-80's ford pickup had no power assist in the steering.

And a much larger steering wheel too. Bus size... well not quite.

Hehehehe... you already done this! Didn't you get your extra 10% fuel mileage improvement?

To be honest, since I claybarred, swapped back to the normal chip, fixed small fuel leak, adjusted the valve timing and changed the engine mounts (one was fooked!) my average has gone up around 3mpg (16.7%)! It reckons I'm getting 24mpg around town too at times with an m30 driving 'normally'... I think not. Time to get my calculator out!

Sounds great! Make sure that wax is still there. Clay bar is once a year thing.

I was told by an old guy once that WW2 air staff were told to polish the wings of the 'Spitfires' to keep their speed up. I don't know whether there was any truth in it, or if it was just a wartime morale boosting exercise, but with the E34 having the aerodynamics of a fridge then anything may help!

Believe it or not: smooth surfaces have less drag and at higher speeds this is all the more interesting. So it may seem silly but a grimy car will consume more fuel going 120-140 km/h than the same car being spotless and waxed.
Also, the E34 does not have the aerodynamics of a fridge: Cd is 0.34.

A Cd of 0.34 eh? How about dropping it to 0.17 like this guy?

I just plan my route to drive down hill both ways to save gas

sometimes I turn around halfway to my destination when I realise I just don't want to spend the gas.
