European ignorance: What oil and oil filter?

[blown871]

I had put 20/50 synthetic in my motor. (very similar to yours) It did NOT like it and started to smoke like a freight train. Went back to Good old fashioned motor oil.

What do you call "good old fashioned motor oil"?

Dan,

I live in the Netherlands. My SPF has a 351W stroked to 427 cu (7lt). I use Valvoline VR1 20W50. Cold oil pressure is about 65 psi and hot about 62 psi. This is racing oil and it has more ZDDP as normal, which is good. Not for modern cars with a catalytic convertor in the exhaust. Just for old cars or racing cars. Sold for prices around 50 euro's for 5 lt Not cheap, but good stuff). My engine takes about 5 lt.
Do a search on the internet and you will probably find a dealer that can send it to you. I buy 10 lt at a time, which saves some shipping costs and I have some spare oil.
Good luck.

BTW It normally is good practice to stick with the oil the engine builder recomments.

Good tip with the VR1 oil. I'll look into it

Do you mean oil pressure at idle? I always read that anything above 20 psi at idle is fine and then it should go up approx 10psi per 1000rpm.

Can someone enlighten me what oil pressure to expect? Yesterday with the oil at around 70C or 160F, I had around 45 psi at 3000rpm. Didn't push it since it was too cold for the engine to warm up.

With my previous Cobra's (I had three before this one) the oil pressure was between 40 and 50 psi (driving around). At idle it was lower, about 5 to 10 psi, average maybe 7 psi. It did go up when driving, but not 10 psi per 1000 rpm. It went up going from idle to maybe 2000 rpm and then it was pretty stable. Ofcourse cold psi was higher than warm psi.
From what I have learned: if you have the correct viscosity the psi goes down only a bit ( max 3-5 psi) from cold to warm. It should be between 20 and 80 ( at 80 psi the hoses might burst). My pressure stays pretty constant from 2000 rpm and up.

Just my 2 cent. If I am wrong, someone will correct me.
