If you look in the owners manual says to use 15W-50 or 20w-50 in these last century Porsche's ,a 5w-30 ( this century viscosity ) will cause very low oil pressures & more blow by( oil getting past the rings ) , but worse still increases the risk of damage to no 2 con-rod bearings at high RPM + the low oil film strength of a 5w-30 will increase cam lobe wear

Thanks, I never knew that viscosity would do that. We dont drive the car that much and when we do, it's only to 'cruise'. No high speed or competitive or aggressive driving. But in a few thousand miles, I'll change it out and get 20-50 this time.
Today, we took the car out, no issues at all. No smoke at all. The oil pressure fluctuated, according to engine rpm. At idle, it was around 2 and driving at 60 mph, it was around 4. When it was a quart low on oil before, it stayed at around 2 1/2-3. Now it's fluctuating.
This is our first 944 and all this is new to me.

5w-30...not a good idea.
Listen to experience [Bruce/Sean]...and learn the easy way. Besides being too thin, hot and cold, for most North American climates, that Castrol is most certainly not up to par in the anti-wear department...not enough Zinc or Phosphorus for our high-loaded, flat-tappet, engines.
Will defer to Bruce/Sean, but I would look for Zn and P counts in the range of 1200-1400 ppm. Much more than that is usually reserved for racing applications...and harmful to the long and prosperous health of your catalytic convertor.
And while synthetic oil won't hurt your cause, it's not necessary for your [non-turbo] application.
Happy motoring...

You might try an additive just for flat tappet engines..One I'm thinking of is ZDDP along with phosphourus additives. I'll get back to you on the brand later today..I want to check the zinc and phosphours levels..EPA doesn't care about your engine or your camshaft..they just want the air clean, and to hell with anyone who gets in their way. Electrics anyone?
