Don't fix something that 's not broke.

This is how I usto be until I sat down and did the math. Running with a dual bypass (or even single bypass system), changing filters, and sampling like I should I would save over $250 a year alone over conventional dino oil. That was even after figuring in buying the dual bypass system.

Today's dino oils are lightyears ahead of where the usto be and for someone who doesn't rack up alotta miles or has a vehicle with a low oil capacity the switch to a long life synthetic really isn't for them. I rack up enough miles and have a high capacity so it benefits me.

Got it Diesel Nut, thanks, looks good.

Amsoil recommends 15K oil drains or once per year on Diesel vehicles using Amsoil filters. Longer with Bypas filtration and oil Analysis.

On gas vehicles like your Ranger, its 25K miles or once per year, whichever comes first. Again, longer with bypass filtration and analysis.

Kinda changes the math.

I run 15K in my truck, even with all the fuel I have. I also have a BMK11 siting in the shop just waiting to be installed.

Good point, when you say High Capacity, how many quarts? Not running the miles you run, it's not for me and I prefer to change oil every 3000 miles to keep it fresh. A good filter like K&N is important, filtering is the key like you say.

Amsoil offers a few different diesel oil grades. For those of you that run Amsoil, what grade do you run? What are the tempatures like in your area during all the seasons?

Without getting into a brand vs. brand debate along with oil analysis, I've been sticking with regular ol' Rotella 15W-40 through the whole year without any trouble. I wont be doing a change until the winter is over, I've heard so many good things about Amsoil is why I ask. According to Amsoil online store, some of their diesel oils aren't CJ4 rated, the only is their 5W-40. Not that it really matters for my 01 that it's CJ4 but I was just saying it for the record.
Anyone run 5W-40 year round? I guess I could've switched to 5W for the winter.

Another thing is that in my factory manual, 5W-40 isn't even listed; I assume because 5W-40 diesel oil wasn't available in 2001?

Haven't changed over yet, Lord so I can't be much help on this one.

No prob,

I think I'll go with Amsoil next time around. Just not sure if I want to stick with 15W-40, or run 5W-40 year round, or just 5W in the winter.

I'm thinking I'll go with the 15/40 to start. I've already got the Mobil synthetic of that weight now, I'm going to stick with that.

Correct. 5W-40 oils started coming to market as they are going to be one of the primary oils for use in the new 2007 emission equipped trucks. I run Amsoil HDD 5W-30 in my Dodge year round, and it is a diffferent animal than most guys know (the oil is). Most guys think a 30W is too thin of an oil to provide proper wear protection. Actually, the Amsoil 5W-30 has a stronger film strength than even the Amsoil 15W40.

Yet another good thing to know, I've run 5-30 in several of my vehicles, but the gas mtrs, wasn't sure it was heavy enough for the diesel.
