<div>Is the consumption of damper oil dependent on miles driven or on time between refills (even if the car is not driven)?
<div><br clear="none"></div>
<div>My reasoning: it is hard to imagine where that oil is going but if the carb casting has porosity or some other leak maybe that is your problem. Perhaps it would leak out regardless of amount of driving. </div>

<div>For the SU experts ..<br clear="none"></div>
<div>Have posted about this problem before - and no, it has not gone away.</div>
<div>Bought new (not rebuilt) HD8 carbs from SU/Burlen about 7k miles ago.</div>
<div>Problem is excessive use of damper oil.</div>
<div>Have to top up about every 1.5 tanks of gas usage.</div>
<div>Ultra careful about filling properly and to feel resistance about 1/2 in above the thread.</div>
<div>Have tried all grades of oil from 20 wt to thick gear oil with no change apart from accel. response times. Currently using SAE 30 nd.</div>
<div>SU have no real ideas either.</div>
<div>They are encouraging me to purchase new dampers - pn
AUC 8112HB ... pricey too.<br clear="none"></div>
<div>I am not convinced that will solve it but will do so.<br clear="none"></div>
<div>There is some very minor scuffing on the valves. See photo.</div>
<div>The pistons drop freely and there is the classic clunk when raised 1/8 in.<br clear="none"></div>
<div>Perhaps this is normal ? maybe other owners don't check their dashpots as frequently ? heavier springs to limit movement ?<br clear="none"></div>
<div>any ideas as to what gives most welcome ?</div>
