The Amsoil Ea oil filters the best filters that I have come across and I have used them in all my vehicles for years along with their synthetic oils....... Just look at the "construction" of the Lexus Ea oil filter compared to the OEM and you will see what I mean. Oil Filters are the most important part on an engine no matter what type of oil (synthetic or dino) you use so why "cheap out" on the filter.

do you have a source for these EA15K49-EA filters?

I calłed steve at luxury Motorworks the luxlink guy to ask a few questions about oils.

he mentioned he tested the TGMO long ago and it was not as slippery internally as other oils and he was using other oils instead.

In this mornings conversation he also mentioned a lot if not all of his ls460’s with high miles on them were using oil. Some a quart per thousand miles.

i mentioned the possible different formulation from lexus’s engineers to retain long term ring seal.

He had not heard this before. Frankly was not interested in the info.

interesting that his testing showed that the TGMO is less slippery than most of the other oils he tested.

to my mind that matches the need for a particular amount of friction between the rings and cylinder walls to retain the seal versus have oil consumption issues and more oil needed to be added between refills.

mine at 2k mikes using TGMO shows no consumption at all.

previous owner had a independent shop do his oil changes and I noted they used valvoline bulk oil in their shop.

when I get a chance I will ask Star motors about customers ls460’s oil consumption issues if any and report back.

the idea that Lexus engineers speced the engine and its particular oil to preserve ring life is not unexpected.

if I furnish my valvoline quick change oil location the oil they do the change including a stock filter for $39.

$100 for 5k Miles oil I am ok with.

any one exclusively using TGMO at 5k intervals having oil consumption issues?

k

I am sorry I offended the gurus here by my relating of my research and my contacts info as best I can.

steve did not use “slipper” my words not his.

I think he said he measured the power needed to turn over the motor. No exact rpm mentioned. No test parameters.

no temp chart at test conditions. No Dyno info. No altitude compensation correlated.

he menrioned he was trying to forget all this old stuff as it was it part of his busy business model doing multiple brands in a busy shop.

he used to supercharge and nitrous inject sc430 long ago. Failure points according to him were the ring lands from detonation. He was the group buy guy for his personally developed lux link external control for the sc’s side quarter windows and to automate the tops operation. Three generations of lux links.

he had never mentioned his testing of various oils in LS cars until today.

i am starting to wonder why I bother to post stuff like this.

he stated the TGMO took more power? to turn the motor over. Said it was junk compared to the other oils tested however he did it.

Matches the posts here that toyota/Lexus specified different additives from Mobil on their oil versus the std Mobil 1 with “advanced friction modifiers”

lots of posts here about oil consumption issues using “synthetic oil.”

Most here do not use TGMO I assume as it’s more expensive and normally not available at independent shops or quick change drive ups.

steves mention of non TGMO oil use, higher power needed to turn over the motor with TGMO and the long term increased oil use and various posts here regarding Totota having different specs for their uses has me leaning towards a connection.

hundreds of oil posts here I assume since 2007.

bobtheoilguy probably did not conduct a 200,000 comparison test of possible oil consumption issues with the various oils.

We here have more info to make choices based on real world results.

many mentions of 150k oil consumption issues here.

Then the 346k guys dealer only results show up. He brought his in as his was starting to use a quart of oil between changes.

Read his service file?.

i build small four stroke off road race engines. I had oil consumption issues using the latest friction modified oils.

went back to non friction modifier oils and a 50/50 Rotella white container oil and the oil issues went away.

if I remember the posts TGMO has more zinc than std Mobil 1.

does not surprise me that the Lexus engineers as stated built the engine and the exact oil to match.

would be surprised if they did not conduct testing to verify their exact formulation for long use.

toyota in .torrance had a large group of dynoes according to my buddy who was there.

i assume japan had more?

but saving money is of major importance to some. With no other factual input most pick by price.

why would anyone think the TGMO was different enough to source it and use it?

oh the reports and results posted here?

Whatever you feel is comfortable with...,

my personal tests on my 300 plus complete engine builds involves a leak down test always..

harder to do on these. Manual shows cranking compression pressures at a specified rpm.

have never seen anyone report testing their ls460 for compression.

if a motor uses oil a compression test serms normal to me.

and i switch oils to higher friction ones to hopefully reseat rings. Works almost very time.

4 valves per cylinder, 12 to 1 compression ratio medium rpm Austrian off road engines.

your results may vary. Pretty sure I have the info I need for my uses.

Everyone can decide for themselves...it’s you nickle

Steve Larson of luxury motorworks in Monrovia apparently thought that if the oil in the motor did not allow it to turn over with less power consumed that its lubrication qualities were not as good as other oils that allowed less power consumption or some other unit of measurement.

my post was that he may not have realized that the measurement he made may not have taken in all the properties of the TGMO. The idea that Toyota intentionally speced the oil to not be the lowest possible friction.

Like having a much longer ring life by NOT being the lowest power use in cranking the motor over.

His oil judgement was simply how low friction an oil was.

most would agree that that measurement was the most important.

my post was that that does not seem to be true.

and the longest engine life seems to use TGMO.

if others here can contribute that at 5k oil changes their ls460 went 250k or more without TGMO and no oil use.

we seem to know from a lot of posters that using TGMO and 5k change intervals resulted in no oil use at those kind of miles.

i agree that the 5k helps.

but is that the key or is the exact oil a contributor to this.

In iother words can I use bulk oil at 5k changes and get the same engine life results as using TGMO?

lots of owners here. Let’s see.

old enough and miles enough that the info should be here.

anyone get 346k miles at 5k changes with non TGMO and no oil use?

This is what just doesn't make any sense...how did he determine "how much power is consumed" by starting the engine? And when you start the engine, there is very little oil in the engine. Its all down in the crankcase, so at that moment of "engine turnover" theres not a whole lot of oil in there.

I think the issue with your question is that what we are talking about when we say "TGMO" is Toyota branded 0W20 synthetic oil. That oil has only existed since about 2012, so you won't find cars really out there with 250k+ miles using only TGMO.

There are other oils that are "Toyota Genuine Motor Oil" or "TGMO", but thats not what we're talking about.

Also, unless you buy the oil and have it used, you don't know whether thats what you're getting or not. Most dealers use off brand drum oil, and only sell TGMO in quarts at the parts desk.

I agree and the part I highlighted "soot, carbon", etc...I think that's the part people forget. Oil does get "dirty". Carbon is real, soot is real. The filter cannot take that out, it just circulates and circulates around inside your engine. Changing your oil removes that and at least gives your engine a little break from those contaminates for a spell. You might get?? I don't know? A couple thousand miles of driving without that stuff really saturating your oil. On the flip side if you're going 10,000 miles or more that stuff is saturated in your oil/engine. I think of it this way, when I change my oil at 5,000 miles it's "dirty" at has a gritty feel to it. I can't imagine taking that nasty oil out, pouring it back in the engine and letting it go for another 5,000 miles. I know the additive package still has remaining life, I know there's still cleaning detergents in it...I just feel it's better to put clean, new oil in there and replace that saturated filter.

I have heard/witnessed first hand that these engines do start consuming oil at "higher mileage". You'll probably never experience that because you purchase new/newer cars every few years or so. Mine didn't start using oil until it reached 150,000 miles...up until that point? I'd use almost zero oil in 5,000 mile oil changes. I did try to extend my intervals out to 7,500 miles for a short time - I found that anything past 5,000 miles the car would use oil - as if the oil had sheared or something...probably added a quart/quart and a half between 5,000 to 7,000 miles. Always used a high quality synthetic, whether it be Mobil 1, TGMO, Castrol, Valvoline.

But when my car reached 150,000 miles, everything changed. Then I started using oil before the 5,000 mile mark. At first a couple quarts. Then when I reached 170,000 miles I knew I kind of had a problem. I was using a quart every 1,000 miles or so. Oil began coming up into the intake through the pcv system - a sure sign the rings were worn - performed a wet compression test and yup...rings.

Lots of cars are using oil at higher mileage, especially because of these lower tension rings they started installing to increase fuel mileage. Some start using oil sooner than others. I think if you can make it to 150,000 plus without consumption issues you're doing ok nowadays. And even if you do, you can probably get another 100,000 miles out of an engine with some care and attention.

I think times have changed in the engine department days...direct injection, rings, turbos, timing chains, higher compression, variable valve timing, thinner oils...all have quietly dramatically altered engines over the past 7-8 years. I think it's an adjustment period for the industry. And I think Lexus will be way ahead of the game.
