what are the disadvantages and advantages of having oil or gas dampers

[martyc]

gas is more stable as it cannot be altered in state under temperature and offers greater consistancy and performance. the only downside with gas dampers is that if for any reason they fail (due to age wear etc) the gas will escape leaving little to no damping effect, where as with oil the loss of the damping medium will not be as immediate, unless you actually manage to cause severe damage to the damper body (been there done that not good lol) but oil under pressure(therefore temperature) thins out producing loss of damping effect, can foam or froth, or turn to a vapour like state where it is no longer effective as a damping medium as in this state it can be compressed easily (where as with gas dampers the gas is pressurised so doesn't suffer from this problem) yet again causing loss of damping effect under pressure/extended hard driving. hope this makes sense and helps....

so performance wise would you opt for gas or oil driving on british roads with there being loads of bumps and pot holes in the roads

gas. oil dampers are old news and have now been superceded. all the top brands (spax etc) use gas dampers

only got to fit one of my gas dampers last night with rain and all that.so at the minute im driving round with 2 oil dampers on the back oil on the passenger side front and gas on the drivers side.and all ready you can feel the differance when i turn corners it feels good when i go over speed bumps its great with my 17s on.
