You didn't. I just back figured it using your style of reasoning. You're saying that it's cheaper to use the FS2500 at the cost of their filters vs. Amsoil. You also said that you're changing them out every 10k.
Now you're telling us the OEM recommendation ..which is 25k (that's about normal for that size engine).
So ..you're servicing your FS2500 at TWO AND ONE HALF TIMES the OEM schedule for the full flow and the sump.
That's 2.5 filters per OEM scheduled event.
This is opposed to 1/2 that amount of bypass filter service with the Amsoil.
The full flow filter recommendation from Amsoil is simply because it's not their product. Easy enough to reason there.
You've reasoned stuff very carefully to defend your choice ..but you've configured it all wrong.
You're going to do 5 service events beyond just topping up using your FS2500 compared to Amsoil's recommendation.
Again, if it makes you happy ..more power to you. Enjoy the service intervals. I'll attempt to get up to speed with that
The basic difference in terms of filtration is simple. If you're willing to use tp/pt or other cartridge like filters ..there are choices. If you want a spin-on ..you can get the mediocre OEM offerings ..or you can get an Amsoil.
I can configure a 1um cotton wound canister bypass filter for the same costs as Amsoil and a HECK of a lot cheaper than the FS2500. Anyone can. They just need the room to fit it ..which you have. Filters are about $10 each ..and will probably last 2X as long as yours and probably comparable with Amsoil's spin-on.
Yeah, but the cost of filters is far less than Amsoils, so not a problem doing 5 service events in the time of 1 Amsoil event. Especially since Amsoil recommends dual BP110 filters for the unit on an engine this size. At even the preferred customer price, it's almost a wash on cost comparison.
Also, it takes a quart of makeup oil for a FS2500 filter change. Considerably less than a change of Amsoils dual filters. And since oil is usually added by the gallon to a class 8 truck engine, if it is not on the add mark, I won't add any oil just because I changed the bypass. Can't say that about Amsoil's setup.
Regarding 5 more service intervals than Amsoils. Not a problem. Especially since I do a complete under chassis grease job and inspection at the same 10K mile interval as the bypass filter change. And since it only takes a few more minutes to do that, it is really not an issue. Got the coveralls on anyway and all it takes is a 3/4 socket wrench and a few minutes. Hardly a factor compared to greasing the entire under side of the truck, inspecting all components and making sure the brakes are adjusted (even though it has auto slack adjustment... they never seem to come out even all the time).
Sooo.... 5 FS2500 filters at under a 1/4 of the cost each of a dual BP110 set of Amsoil filters and no full flow filter change like Amsoil wants. Also a complete painless install kit that requires no more than an hour (unless you take more than one smoke break like I did) and you don't have to waste time and extra cost having hoses made to specifications somewhere else like I would with an Amsoil setup, and I didn't have to worry about making any brackets for the install, routing issues, or obtaining any extra fittings or if the ones I would have gotten wouldn't be the right size for my engine oil ports.
In the long run.... yes, it is cheaper or at least a breakeven compared to Amsoil's setup, but the time savings in getting it installed and up and running was a real cost saver of my time.
Look... if anyone wants a Gulf Coast, Amsoil BP, or whatever is not my concern. Just about all the bypass filters on the market do a good job and the differences in quality are so minute as to fall into the purvue of the arcane. But for ease of installation, ease of maintenance, Cost of operation, and return on investment, the FS2500 won out. Gulf Coast required too much oil for a change (especially if you are using synthetic) and the price was not that great. Truck came with an OPS-1 on it, but could never get it to operate right, so took it off. Amsoil's setup seemed like a hobby project from Popular Mechanics to get it installed and working and would take up too much of my valuable time. Look... I drop over 145,000 miles a year operating and maintainging this truck and still have to manage the books, be on a bowling league every weekend (yes, even though I truck, I have a life), and have a house and 40 acres to take care of. If someone wants to play around with setting up a bypass on their vehicle as a weekend fun project, that's fine. I didn't. So.... Amsoil didn't get a second look. Even though it is a good product, if they can't cater to the customer.... oh well. But then, I guess they never were really concerned with market share. It shows.
