Why do people use lucas "oil stabilizer"?

Most of these sort of treatments are just polymer chain additives.
As they heat up they expand and link up with the oil molecules.
The effect is that the oil thickens up as it heats up.
More accurately stated it thins out more slowly.
When this was discovered it enabled the creation of oils that weren't mono viscosity oils.
All modern oils have this type of additive already.
The reason they add this is that the film/shear strength of oil is directly proportional to its viscosity.
It is not the viscosity they are after but film/shear strength.
Viscosity is actually bad but acceptable up to a point.
From a mechanical point a good oil has low viscosity and high film/shear strength.
The the correct concentration of this type of additive just keeps the viscosity and therefore the film/shear strength with in acceptable levels over a wider temperature range.
Adding to much can most defiantly be detrimental.

 

I think its frickin hilarious when a guy says lucas is bad for your motor then goes onto say he runs 100k between services.....thats sounds so dang stupid

lucus oil is increased my mpg, more power and stopped oil leaks in my 3406e w900 bullrack pulling 6.5mpg rig, lucus rocks and theirs my proof!!!

 

C'mon Allan, I really want to know about these 1.5 mil Volvos. I'm serious. I'm totally impressed. Is it the 11L from way back? There's an old guy at Caneda with an old 90' something Volvo, huge miles on that one as well. I know there have been a few M11's and Series 60's that have gone that distance as well.

 

One guys analogy of taking an engine to 1.5 mil without doing rods and mains because of Lucas does not a scientific case make. I ran an N-14, using only Kendall 15w40, Baldwin filters, 30,000 mile oil changes, no bypass filter to 1.5 mil and it was never opened up except for running the overhead. Still got 7 mpg average and used only a gallon of oil every 8-10000 miles... and no leaks. I would much rather see serious case studies that show any dramatic improvement in a controlled environment that LOS makes a difference. None are available that I know of. All that I have heard so far is nothing more than brand loyalty. Nothing wrong with that, but it hardly makes a definitive case for the product. I am one of those "I need a schematic, logarithm, diagram, chart" kind of guys for detailed analytical information about a product before I decide to put in on or in my equipment. Being a hot seller at the truck stop does not qualify.

 

What is your response to the synthetic LOS, it is no where near as thick as the traditional stuff. I have used it along with synthetic Mobil 1 for quite sometime in my commuter car, it's now at 273K and shows now signs of slowing down, it also it averaging better mileage now than it did when I purchased it.

 

It can be used in all those different types of sources because it is simply a petroleum based additive. It's purpose is it add lubrisity.
