oil pressure not good

[shag]

Hi guys changed the oil on my williams 2 days ago everything went well took it out and at cold start up getting around 1.0 bar at warm sits at 0.5 or there abouts when driving the pressure doesnt seem to go above 2 bar even with full throttle i know its not the guage as the cars lost half of its power lol any ideas as its waffled my head cheers

Get a mech gauge on it to check!

loss of half power seems it's not firing in all cylinders as these clio's only have one coil pack and if that goes..well you know yourself.
as for oil pressure did you change the grade of oil? filter genuine?

[Wobba]

What was the pressure before?

If you used the same type of oil thickness as it had before it could be the filter, as some give better or worse pressure.

Just recheck the level and oil filter and drive it till it blows up. Don't worry.

top end or bottom end knock? top end and very likely oil aint getting up there hence the low pressure
