Lower oil pressure with camguard

[Bavafa]

I was wondering if any one has experienced a lower oil pressure when adding camguard additive? I did an oil change and have added camguard, about 9oz in 7Q oil and my oil pressure was at the lowest that I have ever seen in my engine. It has been always stayed between 78-85 PSI depending on temp, but the other day by the end of a 30 minute flight it was at 56 psi with the oil temp in its normal range of 181F

I've not noticed any significant change in my oil pressure with CamGuard added to the oil. I'm running Phillips 20W50 multi-weight oil and put in about 3/4 of the 1 pint bottle to 7 quarts oil. On my long trip to Idaho last month, there were periods of long climbs at slower airspeeds where my oil temps hit 200 and oil pressure stayed right around 80 psi.

I use 8 OZ of Camguard to 7 Qts Aeroshell W100 Plus, no change in oil pressure or engine temp noted in 300 hrs.

Did not notice any change.

What rpm was the engine running with 56 psi? As low as 25 psi is "in the green" at idle rpm.

Another datapoint for you - I've used Camguard for 2-3 years (wow, did you see what spell correct did before I changed it?) and have never noticed a reduction in oil pressure.

Thanks folks for sharing your experince, it seems it was a mistake on my part that I looked at my oil pressure at very low RPM (800+) . I went for a short flight again today and all is normal.

Good News... Camguard is Good Stuff!

Camguard and Aeroshell W100 Plus. I think that is redundant. Maybe I am wrong, but the Plus has almost the same stuff as the Camguard in it. I have been using Aeroshell W100 and adding Camguard at the oil change and then use Aeroshell W100 Plus when adding oil between changes in my Columbia 400.

Lycoming seems to agree. I just watched (last night) the DVD that came with my new engine and they say this exactly, "Plus" does not need Camguard. Has this changed?

The Aeroshell Plus has 0.9% Butylated/isopropylated triphenylphosphate anti-wear, 0.05% rust inhibitor and 0.5% copper corrosion inhibitor.

Camguard is 100% active and when used at 5% provides vastly improved performance over the Plus. It provides 25 times the rust inhibitor, much better anti-wear performance, true anti-scuff (does not need activation), deposit control (the only aircraft oil product that offers this) and seal conditioning (the Aeroshell anti-scuff attacks seals but Camguard protects them). Here is a 24 hour test conducted on a new push-rod tube seal after heating the Aeroshell Plus (or 15W-50) with a little water and a piece of copper. http://aslcamguard.com/aircraft/test...-conditioning/

There are no chemical similarities between Camguard and the $0.15 worth of additives found in a quart of Aeroshell Plus.
