Detergent vs. Non Detergent Oil

[ultrarunner]

Drained the oil, found no sludge at the plug/screen and could not feel any with my finger on the bottom of the pan. Used 10w30 with a new filter. Thanks for all the discussion on this matter. 8N Nut

Should be fine...

Just keep an eye on it and enjoy it...

you did the right thing for that ford.

I must have 20 of them oin the barn.. all different color and flavor.. all on detergent or high detergent oil.

many I did sever flushes on to get tar out.. manyt I dropped pans and cleaned blocks.

never a problem going with the 70 year newer oil technology.

yeah. I've heard a *few* stories over the years.. my sisters brothers girlfriends roomate knew a guy who's dad had a truck that someone else rode in.. well that rider had a tractor that broke down after an oil change.. must have been that darned new oil..

The shop where I worked during High School rebuilt Ford motors with poured babbit bearings... mostly for the Model A and T guys... also some for Ford Tractors...

Some of the engines that came in had animals nesting in the block... others, no telling what they had been running for oil.

Still others look good with good compression with shot bearings and the dippers plugged solid...

Without a filter... all the sludge has to go somewhere if it gets back into suspension.

On my own engines... I wouldn't run detergent till I dropped the pan and removed the valve cover to give everything a thorough cleaning.

The shop owner had nothing to gain by telling people to be careful with oil... actually preventing bearing problems was bad for business...

not even remotely related.

engines that have been setting open OBVIOUSLY have to be taken down and tanked before use... not even related to this discussion ...

ford tractors HAVE OIL FILTERS

N series 39-52 use a napa 1010G

53-64 use either a 1452 if a spin on or a ch6pl if a canister.

65+ you still see the 1452 spin on used, as well as another canister.. a ch14pl I believe..

thus.. again.. NOT related to this discussion, as the machine in question left the factory with an oil filter!

On my own engines... I wouldn't run detergent till I dropped the pan and removed the valve cover to give everything a thorough cleaning...

pulling valve covers on an N don't gain ya much unless you want to squirt some atf fluid on a sticky valve stem.. or see if they are moving when you roll the crank over..

also not related to this thread.

The title of this thread is Detergent vs Non Detergent Oil...

Don't see how shop experience resurrection old Ford engines wouldn't be relevant to the discussion...

As mentioned... procedure varied depending upon the presence of oil filtration.

Thank you for clarifying.

.

the topic is d/v/nd for his mentioned, ford NAA, which has filtration..... thus no variance ??? done deal...

First mention of filter was in post #10...

ALL FORD TRACTORS left the factory with an oil filter!?! That's my point.. the argument was a useless waste of bandwidth!?!? i stated as much starting in post 3, calling for change and new fitler.. then 8, then 14.. etc.. etc..

I've got a Model F motor under the bench that definitely didn't come with a filter... it has sump screen... no filter.

I think we are in agreement as to the filter/no filter and detergent vs non-detergent...

The antique engines I have date from 1905 to 1950.

The Fords from 1911 though the early 30's don't have oil filters unless after market...

The 1905 Olds doesn't even have a crankcase... oil just drips on the bearings and then onto the road.

Can't we both be right?

It is important to point out in any discussion that while modern oils are vastly superior in many ways... they are not better when it comes to flat tappet engines because zinc is no longer part of the formula. Modern oils are murder on a flat tappet engine.

Zinc was removed because it caused catalytic converter problems.

The best ZDDP replacement I've come across is the GM EOS (engine oil supplement) you can get from a Chevy dealer... and my Fords motors like it...

Seems to me that a thread referencing a newly purchased NAA shouldn't have a lot of room for theoretical discussions about engines designed 40 or 50 years prior that are totally lacking in filtration equipment. NAA's don't have babbitt bearings or use unfiltered splash lubrication. Why are those design features a part of this thread?
If the darn thing is so coked up that a dose of detergent oil and a clean filter causes a major mechanical failure, it was probably going to happen anyway.
