    Amsoil Vs Motul Vs Mobil 1 Synthetic oil wars

    Guest-only advertisement. Register or Log In now!
    We haven't had a amsoil, motul, mobil 1 debate in a while heck we can even throw Liqui Moly in there too if anyone wants to talk about it. I've been researching and finding ALL KINDDDSSS of answers on the net. I have a decent conclusion, but I want to know what are you guys opinions and if anyone has oil analysis on there oil please speak up. All I know is that our little 1.8 turbo motors beat up up oil very bad, and it would be cool to have a friendly debate on why you like the oil you like....

    I am not an oil tech so I can't tell you why group III is worse than group IV oils. So it would be awesome to hear your experiences. Summer is right around the corner so your engine is going to be shearing that 40 weight pretty good as it hits into 90+ degrees. Speak up oil gurus.

    ^ Hahaaaaaa. I've used 5w40 Amsoil European formula with great results, and Mobil 1 0w40 for fall/winter. I've never used Motul but the Audi guys love it as well. Which one will shear the least, and burn off the less? I've never used Rotella T6 but I've heard about it a few times. Let it begin.......

    Seriously though, I don't think you would notice much of a difference between the three you mentioned, considering you're comparing all of the same weights and such. I do love the Rotella though. Highly recommend it if you can get your hands on it.

    I used to run Mobil 1. Not the euro stuff as I could never find it, I just ran the 10-30 and changed it every 5k. It worked fine and all, but I didn't like to 10 factor or the 30 factor very much so I looked for something different. I was not about to rely on special order oils, so I never explored the Motul, Lubri/Liquimoly, Amsoil (although Amsoil is getting ready to go in my B6's 02x), or any of those. I don't want to be on a trip somewhere in need of an oil change, or even just a quart of oil, and not have one handy. I've always been a big fan of HD Diesel oils due to their resistance to shear, ability to withstand high temps, and high detergent content all of which being very good things to have if its going into a 1.8T. I spent a lot of time over on BITOG and ended up with 3 candidates. Shell Rotella T6, German Castrol, and Mobil Delvac 1 ESP.

    German Castrol (supposedly available at auto parts stores) I have yet to actually come across... though I have not looked too hard for it.

    Mobil Delvac 1 ESP (available at most truck stops) is a true Group IV HD Diesel oil with fantastic specs. As much as I hate to admit it, from the specs I have seen, it appears to be ever so slightly better at everything than Rotella T6. (2-3 deg here and there but overall minuscule.) Mobil 1 "TDT" (available at Walmart) from what I read is virtually the same exact formulation.

    Rotella T6 is a cracked hydrocarbon and I guess is technically a Group III (last I knew) but it kills traditional Group IIIs (and most Group IVs) in every way. Don't expect it to break down and sludge up your engine any time soon. It's actually pretty effective at cleaning it. It's marketed as a synthetic, carries the "SM" rating and all that jazz. I've seen nothing but rock solid oil analysis reports from it. I know this is not a 1.8t and I don't have one for that motor as I don't put enough miles on it to warrant one, but here's a report from my 2.7T with over 7k miles, lots of stop and go, several 2hr rtips of sustained 3krpms+, a full summer, and part of a winter on it... and no make up oil to dilute any results.



    As stated, I'm a fan. I ran it in my B5 (1.8) when we had it, it's in my B6 (1.8), as well as our C5 (2.7). I run Rotella T6 in everything, hell I even eat a teaspoon of it a day to stay regular and ease joint pain.

    Seriously though... upon switching to it, both my 1.8t and my 2.7t got quieter (for certain) and seemed to run smoother (possibly a placebo)

    Not going to bag on any of the foreign or boutique oils, but don't overlook whats on your local shelves... some of it's very good stuff.

    Used to run nothing but Amsoil. Switched to Rotella T6 and happy with the money I'm saving. An Amsoil dealer on here even says he runs the Shell Rotella T6 over Amsoil. Must say something.

    T6 here. Most of my friends are mobil 1 fanboys. I think it's just because they've seen the Mobil 1 logo in a magazine and really no other reason. Just a brand recognition thing. I used to run castrol syntec. Switched to T6 and the engine definitely runs quieter. I have 034 motor and snub mounts so I definitely feel the engine, and after an oil change it seems like it runs smoother.

    LMAO. Rotella T6 for joint pain ahahahaa. MAN where can I get some Rotella T6, seems like this thread got ran over by it.....you guys are not even talking about Motul haha. Anyways, one thing thats a pain in the ass about Amsoil is you have to order it or go to a dealer who "might" have it in stock. I love there 5w40 Euro formula, that oil can take a serious beating in the summer. The temps do not even crack over 210 degrees during the day, and even cooler at night. Now im feening to try Rotella T6, but where the hell can you buy it? Shell gas station?

    Those VW guys swear by Motul! Too Eerie B6, can you break down your oil analysis for us so we can understand what we are looking at? The report looks nice but I want to understand it, I never sent out an oil analysis maybe I should.

    I think the reason why most of us go for Mobil 1 0w40 is because its so available you can pick it up at walmart or autozone. I wish Amsoil or Rotella was the same. I like Mobil 1 and there filters but I dont want to run it in the summer, the motor will pound it into mud.

    Walmart, Autozone, Advanced Auto, truck stops... all those places. Looks like this:


    Report Explanations can be found here, click "gas/diesel" then just mouse over what you want to learn about:
    http://www.blackstone-labs.com/report-explanation.php

    The comments section is pretty nice as each one is hand written for each client. Even if you don't know what you are looking at, they will mention any issues.

    The gray columns show averages or safe ranges to give you an idea where you stand.

    Problem numbers they automatically BOLD for you... so that's nice too.

    Down in properties:
    Viscosity can show problems with shear (as well as other things)
    Flashpoint can show fuel (solvent) dilution
    TBN [total base number] is an extra $10 and simply put shows the amount of life left in the oil. It is different for every make/model of oil, but on T6 it starts out around "12.0" and works its way down from there. once it gets down to "1.0" it's done and Blackstone considers it no good. You can use that number to try and extend oil change intervals (so long as all the numbers above check out ok), or as a red flag to decrease them.

    I paid for the TBN in the sample above because I knew that oil had been worked pretty hard and I wanted to see if I had killed it or not.

    I cannot, for the life of me, find somewhere close to me that sells T6. I have to special order it through walmart, and they only have the 1 gallon jugs. I run a 30v, and I just want the gallon +1 quart.

    My Walmart sells quarts of t6. Check again maybe? The 30v uses 6 quarts anyway. You should just buy 3 gallons. That's good for 2 oil changes.

    I would imagine the 246,000 miles you have has taken a toll on your piston rings. It's probably more of the issue than the Mobil 1 lol. Have you tried t6?

    I just made the switch from Mobile 1 to T6, so far im loving it, the car feels happier and the valve train noise is much less. As for factual data, I will send it out to Blackstone at 5k, but I have liked it so far.

    Those running t6 in the 1.8t, are you using 5w30 or 40. I want to try it to see if it will quiet my valvetrain too. I've been using mobil and penzoil from 60k until now (93k) but no analysis so I can't say for sure that I've "been using it with no problems".

    I dont use any of those(not saying theres anything wrong with any of those though), ill reveal later what I switched t, why, and the results. I used to run mob1 15-50 on my 2.0 built gt35r car. ran it for 35k miles and all the bearings were just as new and unworn as the day I built the engine. even sold the pauter rods to a vw guy who builds engines all the time, left the bearings in them, and he said thanks for the new bearings lolz
    but I have a question for all you guys, whats your oilchange intervals and what filter? anything less than the BIG MANN filter is uncivilized!

    I went with amsoil European formula and only lasted in my engine for like 3 days until I had to replace my cylinder head so basically wasted $75 of oil. I spoke to Seerlah and he told me the samething he posted on here. Hearing that an amsoil dealer uses shell rotella over his own product is pretty compelling. Right now castrol syntec is what I'm running. I also recently bought 2 gallons of shell rottella from Walmart can't wait to see if there's a difference. But at that price and how great reviews I hear from it looks like shell is the way to go!

    Previous owner ran German Castrol (0W-30) in my car since new.

    I ran GC for the first 30,000 miles. Recently switched over to T6. No ill effects.

    Only difference I've noticed is that the oil runs a little hotter than before.

    ^ This, FNK did some maths and found that 5w-40 ran hotter, but 5w-30 ran cooler, but with less viscosity, basically equaling out to the same. His thread is some where around here, I will try and find it.

    For oil filters I will run either WIX or MANN both are very well made.

    MANN p/n W940/25
    WIX p/n 51191

    Many people seem to like and run the Mobil1 & K&N oil filters (as well as a few others) but I avoid them. I avoid such filters because most are actually made for the small block Ford (351/302/5.0L Windsor). Don't believe me? try cross referencing them. (or look up an oil filter for a 1990 Ford Mustang 5.0L) The can size is ok, the thread size/pitch is correct, but the bypass spring inside is wrong. The bypass spring setting on the Ford filter is typically 8-10psi. Spec for the 1.8t filter is right around 2bar or 28-30psi. Three companies that I know for sure have a proper 1.8t filter are MANN, WIX, and Purolator (Purolator only in their base model, not the PureONE). There may be several more, those three quickly came to mind.

    If you are suspicious as to whether your filter of choice is truly meant for a 1.8t, see what that particular company offers for a SB Ford fitment. If the part numbers are the same, avoid said filter.

    Previous owner took it to a place that put in Total Quartz. Running T6 5-40 on my 1.8T since I've owned it. I can add to what coolgraynemo said about the oil running hotter.

    I run Amsoil European 5w40. So far no real issues other than a lot of caked on oil in the valve covers. Actually I can't really say it's the oils fault because I don't know what's causing it.

    but I have a question for all you guys, whats your oilchange intervals and what filter? anything less than the BIG MANN filter is uncivilized!
    Man. I've been running the Mobil 1 filters for last 5-10k miles I think I might go back to man from what Eerie B6 said, scary!

    Many people seem to like and run the Mobil1 & K&N oil filters (as well as a few others) but I avoid them. I avoid such filters because most are actually made for the small block Ford (351/302/5.0L Windsor). Don't believe me? try cross referencing them. (or look up an oil filter for a 1990 Ford Mustang 5.0L) The can size is ok, the thread size/pitch is correct, but the bypass spring inside is wrong. The bypass spring setting on the Ford filter is typically 8-10psi. Spec for the 1.8t filter is right around 2bar or 28-30psi. Three companies that I know for sure have a proper 1.8t filter are MANN, WIX, and Purolator (Purolator only in their base model, not the PureONE). There may be several more, those three quickly came to mind.

    If you are suspicious as to whether your filter of choice is truly meant for a 1.8t, see what that particular company offers for a SB Ford fitment. If the part numbers are the same, avoid said filter.
    You learn something new everyday! I really need to try Rotella T6 out if its giving Amsoil Euro formula a run for its money. I ran Amsoil for a long time always did justice in my car, mobil 1 was good to but thats because internals are probably squeaky clean never ran synthetic for more than 4k+ but who knows I might be wasting my money. I never got an oil analysis...anyways I own a mustang a weekend driver and I never knew that about the filters!

    Amsoil is really good, never heard about it sludging up the engine.

    Anything wrong about the big Bosch or Mahle big oil filters?

    Aren't these at par with the Mann filter?

    Rotella T6. I will stand by it and nothing else. I tow with my 1.8t and have seen oil temps well above 250 degrees. This is going up 8-10% grades for anywhere from 5-10 mile ascents towing ~4500 lbs. 250k miles on the car, I've been using Rotella since I owned it at 200k. And always the Mann filter.
    I really love the Rotella for the fact it comes in a gallon jug which is exactly the capacity. No need to measure or check the oil level. Always at the top line when I change it at 3500-5000 miles depending on how tough of driving I've been doing.

    LOL. I'm sorry, I was not trying to single you out. The filters topic came up, and you just happened to remind me of something I thought was important to touch on. The bypass valve controls when and how long your motor gets unfiltered oil running through it. I would prefer to keep that to a minimum personally... I think you most others would as well, so I tried to explain why you might not want to use them.

    I'm no expert, so don't take my words too seriously, I just know what brands of filters I have cut apart, or have seen cut apart ...and the specs I read about them from the various manufacturers websites. I would expect the Mahle to be as good as the Mann, I don't know about Bosch. If the p/n is the same "3500" that they use for the Ford, then I'd avoid it.

    T6 and big Mann filters. Just buy them in bulk through ECS or whatever, still cheaper than than Parts store filter. I noticed my temps running a little hot, I don't like it being over 225, but with AC on and some WOTS it ususally hangs around 205, at 20+ psi.

    In my wifes scion I run Syn blend Motorcraft. I know this does not make sense but if we run full synthetic it burns the shit out of oil.

    My car the previous owner ran Mobil full syn and that is what I run currently.


    I am looking for a good assembly lube as I plan on putting my motor together soon, I have used Royal Purple before and it is good but would rather use something known to be compatible. Also open to suggestions as to which oil to run there after.
    Looking for a 6758 EFR?

    for best info, you guys should check out bobistheoilguy.com

    heres what i came up with. guys running the Amsoil, according to their site(if i can remember correctly), you can do the oil change intervals every 30k or a year, which ever comes first. yes, i said 30k lol
    I now use Royal Purple 20-50. The reason being is that if you have a high mileage head with a some lifter noise, it really quiets that down, to almost nothing. Like i said earlier, i was using the mob1 15-50 with no problems, awesome oil, never burnt off, and all bearings were mint, no signs of any wear whatsoever, but i did have that lifter noise that bothered me. So thats the only reason i switched to the RP. Ive also heard that Amsoil is know to quiet the noise down like the RP i now use, but i have no personal experience with the Amsoil so i CANNOT confirm.

    BIG MANN filter & oil changes every 5k-6k
    Also, dark looking oil DOES NOT mean its no good & time for an oil change. Plenty of threads on bobistheoilguy confirm that with oil analysis sheets.

    good luck with all your oil escapades guys
