Speedco rip off

Ditto... I was going to bring that up. Ya beat me to it! There are a number of reputable places that will do complete oil changes and lube for near the $200 mark.

 

SAPP BROS is a very good place too. I have been using the one in Illinois on I-80 for years!

 

i used to use the Cat filters. Fleet guard filters are just as good as a cat filter. i pay enough for the yellow paint on everything else not doin it for a filter.

 

I bought CAT filters once or twice then switched to Donaldson, saves maybe $20 on four. Same micron rating though do not have the sheet in front of me. But can say the canister or construction of CAT filters is heavier.

 

i cant see how the heavier canister construction would do any good. if u ran off road in gravel and had the risk of throwing a rock against the filter and knocking a hole in it then yea the heavier construction would be better.

 

I don't know if I like that Gulf Coast Filter....? I guess I don't like the fact that you have to add 3 gallons of oil every time you change the filter.

My brother has the Spinner II. You can run the oil longer than normal, some don't change theirs till around 50k miles on it.

 

Yes, you can run longer to a point. I honestly wouldn't do it tho as oil has detergents and other additives that breakdown just due to heat and wear. The bypass filters DO clean out the soot and other stuff, but after 30k miles, all the things in a oil that help keep the cylinders and rings lubbed LOSE that property and also you get viscosity breakdown. With the Gulf Coast, you GAIN about 3 gallons of it back, but I'm not sure that is even enough to be honest. Then add the fact that oil is $17 a gallon, and the 2 filters are another $75-100 then I'd rather just have my oil changed all together.

 

Detroit Diesel doesn't seem to agree with you. For their new DD engines (13, 15 & 16), recommended oil & filter change for long-haul applications (over 60,000 annual miles and a vehicle that averages greater than 6 mpg) is 50,000 miles or 1,280 hours (based on using Detroit Diesel's lube oil and oil analysis program).

Not only is the canister of a heavier gauge in the CAT filter but the anti-drainback valve is better, there is a better filtering media in it, the pleats are treated to keep from bunching up (and losing filtering capacity if doing very long oil change intervals OR getting water in the oil), the end cap is a die-cast aluminum piece rather than cheap steel... and there are even more things that put the CAT filter above the rest.

I'm NOT saying the rest are junk... I don't even have a CAT filter on my 3406 right now. But I talked extensively with an engineer from the outfit that makes the CAT filters (at MATS) and even I could see why they ARE better than the rest.

I will now put down the gallon jug of yellow Kool-Aid and step away from the keyboard...

 

I have been doing 50K oil changes since 2001 on three different engines.. two CATS and a Detroit.

My oil samples have always indicated that the lube oil is still up to the job and can go even longer... with one exception. Rotella T samples always came back with poor results... even after 10,000 miles. I was always a rotella guy (at least for 20 years) but I switched in '02.

My local CAT shop foreman advised me to use 'anything except Rotella' in my engines... that was a shock but I got an immediate good oil sample after I switched to Delvac. And my oil consumption went waaay down, too. Rotella may have changed their formula in recent years... I don't know. But my experience with it has not been very good.
