stt Posted April 30, 2005 Share Posted April 30, 2005 After having a quick scoot through the archives Ive found that the soop normally runs around110 degrees c which is what mines on,But when you start it the pressure goes up to max which is around 100psi then as the journey increases it will drop to about 30ish psi when its at 110 degrees c,Does this sound right or am I gonna have to pay big money for something stupid?

Jake Posted April 30, 2005 Share Posted April 30, 2005 Sounds alright. The oil pressure is always higher while the oil is cold but the oil pressure drops as the oil gets hotter and therefore thinner (less viscous). Link to comment Share on other sites More sharing options...
stt Posted May 1, 2005 Author Share Posted May 1, 2005 does anyone else on here with an oil pressure guage read about the same levels??? Link to comment Share on other sites More sharing options...
SimonB Posted May 1, 2005 Share Posted May 1, 2005 does anyone else on here with an oil pressure guage read about the same levels??? Yep, nothing to worry about there. Link to comment Share on other sites More sharing options...

oilman Posted May 13, 2005 Share Posted May 13, 2005 Just bear in mind that oil viscosity is thicker when cold so pressure will be higher. It's around 4 times thicker at 40degC than at 100degC, here's an example: Typical 10w-40 Viscosity at 40degC = 85cst (centistokes) Viscosity at 100degC = 14cst (centistokes) Cheers Simon Link to comment Share on other sites More sharing options...
Guest Terry S Posted May 13, 2005 Share Posted May 13, 2005 Simon in your expert opinion, what temperatures are acceptable on 10-40w 10-50w Say the Silkolene Pro-S oil Link to comment Share on other sites More sharing options...
oilman Posted May 13, 2005 Share Posted May 13, 2005 Terry, Pro S 5w-40 up to 120degC and 10w-50 up to 140degC. If you can get away with the 5w-40 it's a better all round option for performance and economy etc. Cheers Simon Link to comment Share on other sites More sharing options...
