Re: Synthetic Oil?
Phil.............do you have to use a special plug to keep the oil from running out of the dipstick tube since you guys are driving upside down?? :-)

Re: Synthetic Oil?
Good one! Upon scientific investigation in the southern hemisphere oil drains clockwise as opposed to counter clockwise for those in the northern hemisphere. Hence the gravitational pull sucks oil upwards thereby eliminating the need for special reverse engineered gaskets and such on the lower engine components. Just go flush your toilet to see this phenonem and report back on this thread.

Re: Synthetic Oil?
20psi fast idle hot. Nearly the same cold. 30psi max revved. Less than 2K/yr. Jack E/NJ

Re: Synthetic Oil?
I think those are amazing numbers on that light weight oil. Your engine must be "tight" ! I didn't think you could run that lo wt oil and then still get that kind of pressure. I get high, (35), cold, and it will do 15-20 @ idle in the cooler weather, ie: 70* outside or colder, but in the 80* + it drops significantly, and that's on 20/50! Good for you and thanks for the info.

Re: Synthetic Oil?
It's still rated a 20W oil hot. So 20psi at a fast idle doesn't seem too unusual. What I find amazing is almost no pressure dependence on temperature. My 64 & 05 vehicles show same behavior. Probably means viscosity doesn't change much with temperature and thus flows nearly as well on a cold startup as it does after it's warmed up. As Martha Stewart might say, that seems like a good thing. 8^) Jack E/NJ

Re: Synthetic Oil?
The problem with oil threads is that any advantage or disadvantage of one oil over another shows up so slowly that it is darn near impossible to prove any damage (or lack of damage) is due to the oil.
So, for the most part, we are left with gut feelings. Last edited by RalphInCA; 09-02-2022 at 02:41 PM. |

I have the distinct feeling that my gut would not have difficulty distinguishing between cod liver oil and olive oil.

I know, flathead guys don't need no stinking torque wrench, but over the years, I've see a lot oil pan drain plugs stripped when torqued "by feel." Any thoughts on a reasonable torque value to prevent weepage AND protect thread integrity? |
