I may at times prefer to look at it from the "wasting" perspective.

Waste not, want not, like the old saying goes....

 

Change your oil when you're supposed to.

The number one cause of premature turbocharger failure is oil related; either contaminated lube oil, or oil starvation.

Unless your engine is a diesel, the turbocharger will contain the most precision machining tolerances of any engine component. The bearing surfaces on the turbine shaft are typically held to between two and three ten-thousandths of an inch;
that's the fourth decimal point!
(Typically only a diesel fuel injection pump and/or injectors will have more precise tolerances.)
There are abrasives in your oil that will pass through the filter. ( even with a bypass filtration system that only filters 10% at a time.)

There are two enemies here.

One is the very small particle that will pass through the oil filter even when it's new. Most engine oil filters will filter engine oil down to particle sizes of ab out 30 microns.
A micron is one-millionth of a meter.
As these particles build up, they begin to wear on precision surfaces and cause trouble. Changing the oil at the manufacturers recommended interval, such as every 3,000 miles, is a very good idea, but it's an even better idea if your engine is turbocharged because the turbo is more sensitive to these very small contaminants.

The other factor is build-up in the oil filter.
Many people know that, in general, a slightly dirty filter will filter better than a perfectly clean one.
This is due to the road¬block that the dirt build-up causes in the filter medium, which helps to catch more dirt.
However, the fallacy to this wisdom is that when the build-up is great enough, the oiling system goes into bypass.

Did you know that Nadir?
Could you explain how to recognize a filter going into bypass?

As a general system protection, most all engines have a bypass valve so that if the filter does plug, it doesn't cause catastrophic engine failure by restricting oil flow to all parts of the engine.

If an engine goes into bypass mode, it means you're recirculating completely unfiltered oil!
This pictures a whole new awareness upon the importance of changing your oil and filter doesn't it?

When it does come time for the oil change, there is one step that's commonly overlooked by almost everyone-priming your oil filter.
Prior to installing the engine oil filter, if possible given its position, it's wise to fill the oil filter with clean fresh oil before installation.
The filter will otherwise act like an accumulator and drink up the oil when the engine is restarted, which can cause excessive oil lag to all moving parts, such as the turbo!

However, the point is still valid for any engine, gasoline or diesel; a clean engine is a happy engine.
When running a turbo, you should stepup to the highest grade or API (American Petroleum Institute) rating available in your manufacturer's recommended oil viscosity.

It isn't worth even to think about extending the oil drain intervals with our high dollar, expensive trucks.

With that knowledge I really can't understand anyone in the US with that cheap fuel and oil prices to save and extend the oil drain intervals.

 

 

I have nothing more to add to this thread, unsubscribing...

And I just added the premiere member to my ignore list here.

 

with bypass filters the truck can be ran much longer on oil and engine filter

and most high quality filters filter finer than 30 micron

 

So Jay K. Miller, national sales manager for Schwitzer and Gale Banks (BanksPower) are Idiots?


I expected that.

The intended goal was to compare (low) fuel costs with oil costs.
Oil is part of engineering and part of important maintenance costs.

Knowing the fact that not everyone has a bypass filtration system to extend oil change intervals safely, I wanted to show up how important filtration and oilchange within the recommended intervals is.

Of course I know that not everyone has a bypass filtration system!


The point is: How can you save on oil with that low oil costs in the US?

Simply compare the price of an exchange turbocharger unit with oil costs.
Is it still worth to skimp on maintenance?

I feel sorry if someone does not get this.

 

haha, i think you made him mad bud good points though and neat calulation.

 

PIE FIGHT!!!!!
