Ken,
I too had a similar indication in my 912.Thought it was really odd so I
called Dean at Lockwood and just started to describe my oil pressure indications.
Before I could get it all out of my mouth he said "the oil pressure goes up
when you pull the power back doesn't it ? " I said yes but how did you know. He
said that is a common thing with the 912. He said,as Roger did,it has to do
with the ground on the oil pressure sensor.
I replaced my sensor(Westach) with another one due to the sensor reading 10
lbs too low and it still does it. When I pull back to 2000 rpm my oil
pressure "pops" to 60 lbs.
Wierd engine !

Thanks Roger,
Seems like the 912 is unique. Another owner had same problem.
Will let you know how it comes out.

Hi Ken,
Don't bother with new senders or gages. This is normal.

Swift Renewable Fuels
Welcome to the next generation of aviation fuels.
In fact, this is the introduction of the first and only completely renewable fuel.
The current fuel used in piston fired aircraft is 100 Low Lead (100LL). The
United States and Europe have banned the use of 100LL due to tetraethyl lead
which is needed to bring the octane number to 100. There currently is a moratorium
on this ban until 2010. Swift has this solution.
Unlike the current process of refining crude oil to arrive at a final fuel, we
synthetically create hydrocarbons from bio-mass. This creation method is superior
to the existing refining method because we maintain control over the entire
process giving us the flexibility to meet or exceed current ASTM specifications.
The advantages of Swift Bio-Synthetic Fuel are:
Seamless replacement of 100LL (no engine modifications)
15-25% increase in range over 100LL (no oxygenates)
20% drop in pollutants over the current 100LL fuel
15% more volumetric energy than 100LL
No need for stabilizers or additives
