So...How is that Gulf Coast Filter working out?

myself and my boy both have the ops ecopur bypass system. I have a 3406C Cat and He has an N14 Cummins.My cat has the regular cat oil filter plus the old777 spinon bypass filter his just has the regular Cummins oil ffilter. I change my oil and filters at 15000 miles. He changes his at 10000 miles we only send a sample in once or twice a year. Most of the time our oil is not even black when we change it. We both run the Fass fuel system also.

 

Wow. On the N-14 I had in a '96 FLD, I didn't have a bypass on it, changed the oil at 30,000 miles, and took it to 1.4 million without having to open the engine up for anything more than doing the overheads. Kendall 15w40 and Baldwin filters was all it got. Not sure what reasoning there would be to change at 10,000 miles when oil samples are ok and oil still isn't even black. And Cummins has a longer recommended oil change interval. But, to each his own.

 

we have to spend money or pay a lot of tax so we operate a little different than most peoplejust like tires we buy brand new and give our take offs away most people do not understand . We would rather put money back in to our trucks instead of pay taxes . paying taxes to me is like flushing your money down the toilet. We do not live very high like most people do now a days and when we do buy something we usually pay cash.

 

You do realize that you are spending .75 to save .25, right?

 

yeah kind of Oscar but I have almost 2 million miles on a cat engine . I think keeping clean oil in in has played a very large part in that. So have I wasted or saved money. My belief and I may be wrong is that oil has been a lot less expensive than an overhaul.The same with my transmission and rears they have never been touched and I used to be a steel hauler Actually A hog hauler if you know what that is or should I say was

 

the gulf coast filters are paper towel wrapped up all pretty with a sock material, 45 dollars at TA truck stop for 2 of them. complete false advertising. Bounty 2 ply. Don't believe me? open one up. Ive been buying theirs for 8 years and didn't know, just found out and not happy at all. They lied like hell

 

Well said.

I have the GCF2 and almost 100k on oil, samples every 10k are coming back almost identical to when oil was new.

 

How much acid has built up in the oil? And in the interest of fairness, you do not have 100K on the oil. Given the replacement oil when you replace the GF filter, you have effectively replaced all the oil over that time. That is the part of the equation that gets left out in the marketing stuff.

 

Yes, very true, I think that's why you can go so long on the oil. Adding 2 to 3 gallons of make-up at filter changes replenishes additives.

My system cost me about $200, I bought the GCF2 housing w/ filters off ebay years ago for $150. It was a military take off, the other 50 I spent at a speed shop on AN fittings and braided hose. I plumbed it myself w/ a ball valve for easy sampling. I don't go for the GCF marketing but, with my relatively small investment I know I'm saving money. My housing is one of the old ones that say "the original paper towel filter" on it:


The most important thing to me though, is knowing whats going on in my engine by following any trends in the oil samples. Just dumping the oil for new would end the baseline and start all over.

TAN is the only thing I hate about Gulf Coast analysis program, it's not on the lab printout. As a matter of fact you just put that back in my head Cowpie, I'm going to call Jerry about that and if I have to I'll switch labs.
