I'm well used to the arguing that happens in forums. What Dr Haas writes has a ring of truth though because it explains why oil makers are going for lower cold viscosities. To me, common sense is an important tool. We can't all be white-coated scientists in Mobil laboratories but we can try and...

Thank you for that link, Jim. I'm guessing that manual is for a much more recent motor than mine. I expect the oil pressure figures will still apply. I wonder where I could go for advice on plumbing an oil pressure gauge in... Why is reading Oil 101 a mistake?

Thank you all for your thoughts. The green band on the tacho indicates optimum torque between 1500 and 2500 rpm and it certainly pulls best there. I did ring an engine rebuilder here who thought the motor should be developing 60 to 70 psi at 3k rpm, so there's the 10psi/1k rpm out the door. A...

No idea sorry. The only indication I have ever had (owned the vehicle for 10 years) is how long the oil pressure warning light takes to go off when starting cold. This varies depending on the brand of filter. I found in some filters the backflow preventer doesn't even work. Currently the light...

Hi Having read the Motor Oil 101, I have a question to ask. Dr Haas states that at operating temperature an engine should be producing 10 psi of oil pressure per 1000 rpm and this should ultimately be an owner's guide to the weight of oil to use. Can anyone tell me please - and/or point to...
