motoroil bypass filter for trucks does not pay off ??

[Dyxan]

talked to someone from a construction business about using motoroil TP bypass filters. It seems there is no financial clue for them ( investment does not pay of)
How is that possible?
They run 36 trucks
average input numbers:

truck employment: 310.000 miles in 8 years
motor oil filling: 6,6 gallons
standard motor oil replacement interval: 38.000 miles
cost of 1 Liter motoroil 10W40: 2,43 USD
Cost of standard oil filter: 60 USD
workshop working hour cost: 42 USD
example 3Pcs M-30 bypas filter in parallel with an investment of: 450 USD
---------------------------------
ROI calculation after 8 years shows a negative value means a total loss of more than
2800,- USD
against standard solution !!!

How is that possible ?
Does bypass filter on trucks in a construction buiness never pay off???

thanks in advance for your feedback

That seems like a long interval for what (based on the price)does not look like a synthetic oil.

Well that´s what they do i think the make of these trucks is IVECO and they do only what they are told to do by their truck dealer.
They have also some smaller trucks, where they use even some "cheaper" oil 10W40 which costs them only:
1,60 USD/Liter
Further they employ lot of diggers and earth-movers, where they change the motor oil and standard oil-filter just once a year !!

I find this odd..since many diesel engines come standard with their own version of a bypass filter.

I think that a single TP element would be more costly in terms of down time...but they make PT filters (paper towel) that can handle the added mileage.

Most spin-on bypass filters ..make that all ..can't match TP or PT for cleaning. Where they shine is in service interval. TP and PT shine for effectiveness and for cheapness of replacement. You can pay for 4-6 gallons of oil for the cost of the bypass spin-on element.

Where in the heck are you buying oil for $1/gallon?!!?

 

[Gary Allan]

Where are you buying a spinon bypass filter for a buck (or whatever the cost is in how you were figuring)?? They go for anywhere from $15-$30

 

[Dyxan]

Well cost of one filter element was assumed to be 1.70 USD (there have to be changed all 3 of them every..let say 6200 miles ?).

Anyway is that possible that on a truck over 7.5to tonnage (loading) like 18to truck simply even cheapest TP filter (f.e. like Motor Guard) does not pay off ??
This means the oil is also a way too cheap it should be more expensive than people would dare to drain it so easily....

Well cost of one filter element was assumed to be 1.70 USD (there have to be changed all 3 of them every..let say 6200 miles ?).

I can't see a roll of TP costing $1.70 US ..but..

We don't know the normal consumption during that 6200 miles ..but lets' say NONE. That would mean a max of 3 quarts and 3 tp rolls over 6200 miles ..so we add 18 quarts of oil (up to) and 18 rolls of TP over 38k miles ...

Of course there is no savings if the same drain interval is used. How did they figure out the new OCI??

It appears to come down to "downtime" more than anything else. The shop labor is the killer. That ignores something like a grader or loader that has probably 1/2 hour to 1 hour of geasing to do anyway quite frequently.

 

[Dyxan]

new motor oil drain intervall with bypass filter was assumed to be 186.411 miles than.
Sure there has some regular lab analysis should show the real motor oil condition since their machines are pretty expensive
Sure you are right, downtime savings not having to wait every 38.000 miles for 1.5 hours for the oil drain are allready calculated in that as well.
What shall be probably taken is the same time in hours which can be chared to the customer if the vehikel is working (which would be 60,-USD/hour including staff). Still i am afraid it does not help much in terms of ROI calculation....

 

[Gary Allan]

You're right. Oil is too cheap.

Purolator L30003 goes for $6

 

[Gary Allan]

You should not find that one on a OTR diesel. Donaldson bypass filters go for about $15 plust S&H. They aren't the same animal.

..and in that filter's case ..you're looking at around 3 gallons (or half of the sump) in costs.

 

[burntkat]

ah, my mistake. Sorry!

 

[Gary Allan]

No, I see where you're coming from.

It may be nothing more then me seeing expensive filters. I have explored the lower end stuff too. It is (the mounts) available at any NAPA for the L30003 equivalent:

I think this is more along the line of what I'm talking about. Look at the micron rating, flow rate, and size difference:

Isn't the biggest difference between bypass filters the makeup oil required for an oci that's driven by a uoa. No matter what they say about each other, they all filter pretty well. But those paper towel filter changes are almost like doing an oil change and the tp filters just don't have the range for many commercial applications. Some filters like the OilGuard and Kleenoil require very little makeup oil and that has to save time and money. In fact the Kleenoil is very spill resistant and makes practically no mess. The only problem with the Kleenoil is the purchase price...ouch. I think the cost of makeup oil has to be considered when picking a bypass filter, but if it's for your own car, a tp filter makes sense, low cost, cheap filters, and you do the work.
