Synthetic Oil?

Thoughts....I love it, I get a good chuckle and grin when we talk about oil. I love the stories, back and forth on this subject. I'm a regular 20W50 guy:rolleyes:

Honestly fellas, if we keep the oil level between ADD and Full on the dip stick no matter what it is, I think we will make it to and from our desired destinations.:D

Hey life is short, get out there and enjoy/drive those old Fords this summer and keep the oil level...Level.

This is the most level headed response yet! :D

Would also agree with those comments with addition of oil pressure at the gauge. Driving is always the best part for me down under.

Haha. It was trying to do a play on words with comments about the level being on the level.

A working oil pressure gauge is always good too!
 
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?? :-)

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.

Can I get back to you on that one. Have a wire on dipstick to prevent it coming out so yes probably!!
No wonder need to top oil up so regularly.

I've switched to WalMart's 0W-20 full synthetic in my 21-studder 2 years ago. It had been running 5w-20 synblend since being re-done 10 years ago. Jack E/NJ

Curious! What kind of oil pressure are you getting at full heat? Do you drive it much? Thanks

I'm with you, 20/50 Castrol is my final choice and very good results. 1/2 qt every 600 miles and change every 1000!

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

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.
 
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

motor oil is motor oil

🤔 Gotta think about that! I like the u-tube video & think it bears out, the case for Synthetic! While all Synthetic oils start from ground oil or from natural gas, the mfg process differs significantly technically with regard to its internal component engineering, big differences in use & effect characteristics. So in effect, yes Motor oil is motor oil but Sythetic motor oil is Superman compared to Batman. BTW I like Batman too😂!

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.

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

I use 5w-30 Synthetic Oil in my other vehicles & have used for many years & like it. I truly believe I noticed improved performance & what I’ve read it does reduce wear. I haven’t tried it on my 8BA but am considering it. Thoughts?

Use it you won’t be sorry and,I doubt you will have an issue
Just keep a close eye on the level for awhile tell everything settles in
Just my thoughts on past experiences

A lot of great observations here. This one sums it up for me. Have heard about the increased leakage concern. I do believe it reduces engine wear in any engine and that's the decider for me. I'd like to see my flathead last the rest of my life without needing a rebuild. For my next oil change I'm going to use synthetic. I'll use whatever's closest to the original viscosity recommendation though, nothing thinner.



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?
