Fleetguard on Amsoil filter head

[tmarti96]

Seems like I read somewhere that all Fleetguard Full Flow oil filters will fit( thread matchup) the Amsoil Dual Filter setup. If this is so, it seems that any of the Fleetguard filters would compliment this set up. Why not use their LF 777(bypass filter) also. What do you think? Thanks for the input.

Sort of like buying a Dodge Cummins and putting a PSD in it, but hey, to each is own!





The Amsoil filters, By-Pass and Full Flow are superior to the Fleetguards. That is the whole point of using Amsoil's system- the filters.

I have a dual remote on my 2001, and the Fleetguard filters would NOT fit - threads are completely different sizes. Some have discussed adapters that might make it possible; I only know that it won't fit without something more than "standard" set up.

I don't think the Fleetguard LF777 filters down to the same micron level as the Amsoil or Oilguard bypass filters. I could be wrong due to differences in the way each company states their ratings, but Fleetguard was quoting 5 to 7 micron range; the others claim down in the 1 to 3 micron range. The new Oilguard page at www.oilguard.com has some discussions on the different ways of reporting the rating.

For various reasons, including the fact that I like the "factory" oil pressure you see with a full flow filter in the factory location, if I were doing it again today I would chose between the Amsoil single bypass and the Oilguard units. If you go dual remote, be sure to get the CPFF (?) adapter kit and battery bracket. Saves time and doesn't leak.

All JMO, of course.

Thanks HC for validating my sanity (maybe).



I installed the dual remote system not long ago (with the full-on CPFF mounting and plumbing - very trick). From day one I thought there was a difference in oil pressure.



My sense is that the oil pressure at cruising speeds (and oil @ normal temp) reads very slightly less. Of more concern to me, it seems like when the oil press. builds @ idle right after a cold start, it peaks way less than with stock full flow. I've noticed that in this scenario if revs are increased to maybe 1,000, I see the same approx 65psi as with stock. I would be interested to know if other dual remote users have noted similar. Also considered maybe this was a function of the (Ams)oil, but canned that theory (viscosity-wise 15w-40 should be 15w-40, right??)... .



I of course went with the dual remote in order to start oil sampling & extending drain interval - don't care about running the same oil for 50K miles, just wanted to cut down on some wasted oil and $$. Maybe try to run 20-25K between dumps. I'm now thinking about taking my next oil sample and then going back to stock filtration with Stratapore just to see the difference in analysis.

I have the dual Amsoil setup, and used Amsoil 15-40 Marine and HDD for 8K miles. After 5K miles, I noticed drop in oil pressure at startup, rather delay at startup of 5 seconds. Didn't happen before. I had used Rotella for 100K miles. I just wanted to take advantage of Fleetguard(or any other good filters) that I can get locally, rather than being forced to use their(Amsoil) expensive filters. I am not into a 50K delayed drain period. Just want good filtration.

Mike,

I think this is a great idea that would give us some good data to look at! More importantly, I especially like the idea of removing the bypass filter and doing this experiment on your truck instead of mine.

Seriously, I've considered similar experiments like switching between Amsoil and Delvac 1 just to see if I can detect a real difference in wear rates, but right now I'm just sticking to one brand because it would take me too long to collect enough data for me to be sure it wasn't just normal variations in the data spread, or factors other than the oils like winter vs summer driving.

I am considering a bypass system and noticed your prior note regarding single vs dual. If I go with the single bypass, can't I still put a sample valve on the "in" line going to the bypass to get an accurate sample? Oilguard bypass filters are only $11, quite a bit less than the Amsoil. Any experience with their quality?

kwedberg,

I have a single bypass and put a tee at the inlet to the filter with a valve on it. Take the samples from this point and it works great.

Some really like sample valves, others just see them as a potential leak point, or don't like leaning into the engine compartment with the engine running and the fan stirring up enough dust to potentially contaminate the sample. The Amsoil sample pump makes it VERY easy to draw a sample through the dipstick tube.

As to your second question, Oilguard says the Oilguard filter is better. Amsoil says the Amsoil filter is better. I have no data, but believe both are in the same ballpark, very, very good. Oilguard filters recommend 10k replacement inteval; Amsoil costs more but most folks are using 15k to 20k intervals, so when you consider the cost of the top-up oil, it's a wash. Oilguard claims you can go longer than 10k between filter changes with oil analysis. Racor makes a filter that I think will fit the Oilguard head, which could cut the cost to $6 a filter, but I have not yet confirmed this. If either of these checks out, then Oilguard would be more economical. On Amsoil's side, the "spin on" is going to be less messy to replace, and require less maintenance room. On the Oilguard you need about 6 or 7" clearance below the filter to remove the casing, and then you have to deal with an soggy oil filter internal element. If cost is a major issue and you like to "do it yourself", I think I'd lean slightly towards the Oilguard. If you want to buy as many things "prefab" as you can, like mounting brackets, I think you'd be happy going with the Amsoil, because more are using that so all of it has already been figured out by somebody else.

Bottom line: Pick one and get started on installing it; you'll be glad you did.
