What is non-detergent oil for?

I see racks of non-detergent oil around here. The last time I heard of someone using non-detergent oil was about 30 years ago when a 70 year old mechanic refused to follow the oil recommended in the manual because he did not trust the new fangled stuff, "not enough data to prove that it will not fail." My question is: What is non-detergent oil 1. used for? 2. recommended by manufacturers for? just curious

I believe that Roots recommends it for the gearboxes on some of their industrial positive displacement blowers. . . but that might be an old spec. The idea was to let the contaminants fall out of suspension so they would not continue to circulate through the gears and bearings of an unfiltered system. It can be used to lubricate plain journal bearings like those found in old furnaces. It might be suitable for some hydraulic jacks. I think the stuff in stores is mainly there to dupe ignorant customers into buying plain, unadditized base oil for about the same price as a fully formulated oil.

A quart of non-detergent oil in Canadian Tire is something like $3.19 while the cheapest oil Canadian Tire stocks is $1.98, same situation with Walmart, the Tech2000 non-detergent oil is about 40 cents more than normal motor oil. I guess that should be enough to keep most people away from it.

My electric trimming chainsaw uses nondetergent 30 wt oil for lubing the chain. My electric nail gun compressor uses 20 wt ND. Though that's been converted over to my left over 5W-30 synthetic oils since my workers never changed or checked the oil and almost made toast out of the motor. The synthetic motor oil seems to help the damaged motor work ok. My REAL leaky 1961 Chevy Impala use to use re-refined ND oil 35 years ago [Roll Eyes] . That car used more oil than gas. Leaky sidepan gasket in the L-6 motor. My father didn't trust me to change it and he didn't care himself until the motor seized on the way home from a drive-in movie and he had to come and pick me and my date up off the side of the interstate [Wink] . In the span of less than 100 miles I leaked 2 1/2 gallons of oil. Whimsey
 
It's for ripping off the unwary. They then lunch their engines, and the manufacturer in that circumstance won't honor the warranty, so said unwary get to buy another engine too. In many parts of the country, including here, convenience and grocery stores sell off-brand non-detergent "API SA" or "SB" SAE 30 for a little less than they would normal SL/SM oil. All the oil is sold at ripoff prices using the philosophy, "If they need it that bad, we'll stick it to 'em," so the uninformed or those in a hurry grab the cheapest oil. Which happens to be the ND. Some compressors and other shop and industrial equipment call for ND SAE 30 or other ND weight. Years ago, some mechanics used to advise customers to run a quart of ND 30 in a full tank of gas for breaking in new engines. Wouldn't try that these days in most cars, as this would probably clog fuel injectors. I have long advocated banning non-detergent oils sold as motor oil from store shelves. Only cars built before World War II specified and would still use ND. California and some other states have instituted stringent labeling requirements on these oils to alert the consumer not to use it in a newer car, but out here these warnings do not appear. There is no reason for this stuff to be in regular stores because of the potential damage it can cause. As a special-order oil for antique cars, this would be all right, but not to sell to some naive young adult topping off his newer car. This topic has come up before on other threads. On ND oil, some of the other BITOGers believe that "let the buyer beware" should hold at all costs, free market yadda yadda, but I vehemently disagree. Some of the same people would probably also allow infants' elixirs containing opium still to be sold over the counter as was done 100+ years ago. And they would probably still allow sales of fresh bagged spinach leaves containing E. coli bacteria (in the news as we speak, and the subject of a big recall) without warnings to the consumer as well. Hey, caveat emptor!

It's getting pretty scarce here. Been replaced by Super tech and Chevron oil [Cheers!] I needed 4 qts of it for our shop air compressor and I couldn't find any at the local liquer stores. I ended up paying $3 a qt for some @ Napa.

Unadditized mineral oil is great for padlocks, electric motors, hinges, bicycle chains, squeaky casters, whetstones, children's wagon and tricycle wheels, sewing machines, one piece garage door linkages, etc. (The last car I sold privately was a '94 Hyundai Sonata. Three months later, the guy showed up one Sunday morning and demanded I change the car's engine and A/T oils for him. I asked him if he brought any oil. He showed me a cardboard box in the trunk with ten quarts of 30 wt. "SA" oil he bought. I complied - five quarts went in the engine and the other five went in the tranny after draining each. He must've been happy - never saw 'im again afterward...)

This area (San Bernardino county,Ca) was the Meth capitol of the USA for quite some time. [/QUOTE] In one of the rural counties of Northern California (Lake, IIRC) I heard the Sherrif being interviewed on the radio about drug problems and he said that "Beavis and Butthead" meth labs were his biggest drug related problem. A memorable description.

Lawnmower engines sometimes require [still] non detergent oil. I never understood why. Maybe using a detergent oil in an engine that always had non det. oil in it would break up crud and cause damage.

I was down in Texas for a while about 20 years ago and one of the local customs was using non-detergent oils in automotive engines. I would get into vigorous discussions about it. One of the reasons stated was that detergent oil had only 50% oil and the rest additives. That if the det. oil was any good it wouldn't burn off and oil use was less with non-det. Also you were getting gipped because there was less oil and more other stuff, REALLY!

I have used Non-Detergent oil with GM-Engine oil Supplement many times in the late 70's and 80's for the first 20 minutes of break-in of the engine and cam. All my engines ran wonderfully. I refilled with a quality detergent oil...ran another 500 miles and drained and refilled. Worked fine for me [I dont know] This was main stream engine break-in procedure way back when....
