Krambo Posted October 18, 2007 Report Share Posted October 18, 2007 (edited) ...Just adding to the thread and keeping it on track: I now just started using the Amsoil absolute efficiency filter (Ea064) which is the "larger capacity" filter that is sometimes hard to find and cross reference. I also started using their synthetic Oil this time around. My old set-up was a K&N HP2006 and Mobile 1 10W30 Gold cap. Absolute Efficiency Filters Amsoil oil The only thing I miss is the 1" nut on the end of the K&N filter. It just makes it that much easier to install / remove. I am not a big fan of the "extended drain intervals" and with the amount of driving I do with the truck, I will change every 6 months or so. Amsoil has a 25,000 mile or 1 year drain interval when using their Absolute Efficiency filters and newest synthetic oils. I am just not comfortable with that for some reason.

Amsoil has a 25,000 mile or 1 year drain interval when using their Absolute Efficiency filters and newest synthetic oils. I am just not comfortable with that for some reason. Amsoil was claiming the 25,000/1year drain interval long before the new EA filters came out, those filters were only released in the last 18 months or so. My entire fleet here at work runs on Amsoil, we have been using it for close to 20 years. We have never had an engine failure running on Amsoil, and have had several vans run past 200,000 miles on it. We do not go by their 25000 mile drain interval, with the kind of abuse our vans get, we do a full Amsoil oil and filter change every 7500 miles. Personally, I use Mobil 1 with the silver cap and change it every 2500-3000 miles with a fresh AC Delco PF46 filter. Anything is better than conventional oil, which brand/product line of Synthetics you choose is just a matter of personal preference. BTW, Mr. P. and Holty thanks for the tip on the larger filter.

rpss4844 Posted October 18, 2007 Report Share Posted October 18, 2007 Interesting... but oil debates are like color debates--almost everyone gets nowhere, fast... Mobile One, even in the "regular" gray cap is better than any non-synth oil out there, and more than exemplary if we change our oil with any kind of regularity. I never let my oil get older than 3000 miles, but I commute with my truck. Even so, I would never feel comfortable taking any oil past 5000 miles. But that's just me. At that frequent an oil change interval, even conventional oils would be more than sufficient... As a side note, the last time I changed my oil, I went with Shell Rotella (Full sytnth, 5w40)... It's cheap at Walmart in the gallon bottle, and I've heard nothing but good things about Rotella. I run Mobile One in every other vehicle I own. Just my .02... Rotella.... this is the first I have heard of anyone using Rotella in a gas engine. I have a 2005 Fs50 with the PSD and before that I had a 99 F250 w/ PSD. I used that rotella syn 5w40 in the winter months and when I was traveling to new england area. By using it in colder temp it cut down on "romping" and made cold starts a lot easier. during summer I use 15w40. Thats just my story. I am not questioning your decision, just expressing my lack of ever hearing someone use it in a gas burner. Back to the topic at hand. is this taller filter being reccomended really for the ls1. I had an ls1 for about 5 years and i discoved using a taller filter then as well. I started a topic of my own just before this one got started and I have only gotten one reply and it was a link to this topic! LOL! Does anyone know if ALL wix filters have anti-drainback? Is anti-drainback even needed on the trucks due to the way the filter is mounted? It seems that gravity would keep the filter full unless parked up-side down. I have to be missing something here....please explain. Quote Link to comment Share on other sites More sharing options...
sly Posted October 19, 2007 Report Share Posted October 19, 2007 (edited) For those that buy and use premium oil filters, I rifled through the oil filter section at OReilley's last night and found the M1-206 fits LS1's and is 1/2-again taller than the stubby M1-107 called for in the book. I figure hey since they are both the same price may as well get the larger capacity filter, it works too I had 50-psi oil pressure at idle with Mobile-1 5W-30. Mr. P. So, Instead of a 6qt oil change add another 1/2 a quart for the added capacity? Or did you just leave it at 6qts?

Add oil until the dipstick says you're at the right level. Quote Link to comment Share on other sites More sharing options...
OneBadSSS Posted October 20, 2007 Report Share Posted October 20, 2007 (edited) A good rule of thumb for cross-referencing the "taller" version of your favorite brand of oil filter is to just look up the size that's prescribed for the '99-'02 V8 silverados in the parts catalog, because up until the '03 model year the full size trucks/suv's all used the AC Delco PF-59 filter, which is the "taller" version of the currently used PF-46. BTW, the PF-59 has been discontinued and now dealerships only utilize PF-46 filters across the board for LS1 family V8 applications... Just an FYI... Me, personally, I run Pennzoil's Platinum Synthetic 10W-30 ($19.95 for a 5-qt. jug @ Wally-World) with a Super Tech "tall" filter (Super Tech is Wal-Mart's generic brand, but it's made by Champion Labs, same company that makes AC Delco filters! And the Super Techs are only $2.47 a piece!) and I change my oil every 3K miles with great results...

misterp Posted October 20, 2007 Author Report Share Posted October 20, 2007 I dunno about you guys running 10W- oil in your trucks; running 5W- in my truck gives 50-psi oil pressure at cold idle and pegs the guage above 3-grand. I run Mobile1 0W-30 in the winter and Mobile1 0W-40 in the summer and highly recommend it, get immediate pressure/flow on startup and still have 50-60 psi "working pressure". Mr. P.

misterp Posted October 24, 2007 Author Report Share Posted October 24, 2007 I never thought about running a 0W- oil in Texas....I might give it a try next oil change. Not my idea actually - I followed a huge "what's the best oil" thread on LS1Tech (sadly there are many over there) and that led to another site with an actual engineering discussion (between lubrication specialists) on measured lubrication requirements of the Gen-III engines and then a comparison against the lab-measured properties of the current crop of performance lubricants on the market. Summary - most appropriate oil for a road-raced LS1 is M1 0W-40, and with correct filtration change interval is 4500-miles; also a lot of the stuff said about certain formulations was very revealing, i.e. what is really in oil and why AMSOil is different from RP is different from M1 is different from petroleum-based oils. I acutally ordered M1 0W-40 and ran this for a cycle in my truck, and wow what a learning experience the LQ9 loves the stuff and I am a thin-oil convert, I GET IT now! Everyone forgets that these engines are running clearances that are like 1/10th of motors engineered 25-years ago; and you have to change LOTS of your thinking because of this - there is a lot less tolerance for garbage so you've GOT to run the best damned filter you can, which required you run the thinnest oil in the motor that still satisfies the lubrication requirements because this assures you get best flow through the filter as well as immediate lubrication on startup. So on a LSx motor with stock clearances (very important disclaimer) you want 0W-* oil; if you are running forged pistons with say 0.025" cold clearance (common) then you will need thicker oil say 10W-* but you will also want to open-up the bearing clearances a tad to work with that viscosity to assure correct flow and you will need a more 'porous' filter (like WIX) or else the filter becomes a flow restriction. I've got 53K-miles on my truck now, and usually I can start to hear an increase in engine noise at this mileage but this LQ9 is still silent as a new sewing machine, the A/C compressor and PS pump are now louder than the engine noise in fact so I'm sold...

Mr. P. so ditch the 5w/30 and go 0w/40 is your suggestion huh? Quote Link to comment Share on other sites More sharing options...
misterp Posted October 24, 2007 Author Report Share Posted October 24, 2007 so ditch the 5w/30 and go 0w/40 is your suggestion huh? Yes; or the AMSOil s2000 0W-30. Those are my preferred engine oil products. Mr. P. Quote Link to comment Share on other sites More sharing options...
