The 25,000 mile oil? Have you tried it?
 

I got my Amsoil catalog today and they were advertising the 25,000 mile oil. Komptek, have you tried it? If so, did you do an oil analysis?

I personally dont think I would ever try it. I would rather just use good oil that I know is safe and not be lazy and just change my oil every 3months.

Amsoil is safe and it's an excellent oil... they invented the Automobile synthetic oil... just because I want extended intervals does not make me lazy. I'm just want other cost-saving methods. Do you change your oil every 3 months because some fool told you to? If you have oil analysis proof like me, you would know that the 3,000 miles/3 month rule is obsolete and phony.

Do you know or tried anything from Amsoil?

I'm interested to see some results on it. As for me, i've had mine changed every 3,750 miles as per instruction of the manual. Let us know if you decide to give it a shot.

I refuse to join the Amsoil cult. Yes, it is a cult.

well, if you use synthetic oil.. then you're part of the "cult". Amsoil invented the automobile synthetic oil...

You can trust an Air Force veteran who used synthetics in his Jet aircraft or you can trust big oil companies like Mobil who is sucking millions out of people with false advertisments.

You should do an oil analysis to see how your engine is doing and to see if there's life in the oil. Most of the time, oils that are tested at 3,000 miles usually have 5,000 miles of estimated life left. Long ago, I used cheap Walmart Oil (supertech) and tested at 4,000 miles. The analysis said that my oil had so much life left. I'm interested in extended oil because I hate seeing people waste oil by changing their oil sooner. When I'm done with my oils, I will do this Amsoil test on my Tiburon.

I use Royal Purple Synthetic (personal preference) and go 10,000 miles or 6 months on an oil change usually, but that's with a fair amount of racing time thrown in there too.

There is alot more to oil and oil life than you may think. take filters as being one of them. You should also note that every engine is different and results will vary depending on climate as well as engine condition, and many other factors. There is alot more to oils than just reading an analysis to see what kind of oil life you have left....

i use mobile1 15000 oil in my past 3 cars. never had a problem with any of them (not caused by oil any way). drove the camaro with synthetic from about 150,000 to 250,000 with synthetic (castrol i think), my toyota from 75,000 to 175,000 no problems with oil (castrol then mobile1). put synthetic in my lc at 10,000 and it still runs great at 135,000(mobile1).

-even if you use conventional oil technology has far passed the 3000 mile rule of thumb.
-the 2009 kia rio5 i just bought sais 5000 miles on oil changes (it has the 1.6 alpha motor)

-as far as jet engines the synthetic oil we use doesn't break down but it does get dirty and get contaminated so it still gets changed. but consider that a jet engine runs much hotter and much faster than a piston engine.

-also keep in mind that oils can be tweaked to fit a specific purpose. examples- could be designed to have long life, could be designed to give slightly better fuel economy but sacrice some oil life, could be designed for high performance apps, extreme weather. its all give and take with oil so whatever you buy change it when it is designed to be changed and change your filter.

i've always just used regular Castrol GTX and a hyundai filter every 3K. the engine runs smooth as butter and has for the last 60K miles. i don't think it's a big deal to get under your car every couple months, since a lot of little leaks and things can be found by being under there anyway..

Everybody that reads this needs to check out bobistheoilguy . com. I'm not affiliated but if you have any questions about oil/filters/technology you need to look no further.

i change my oil every 3000 miles too. i use mobil 1 synthetic and the car has ran like a champ.

Unless you beat the snot out of your car and use some junky Fram filter, quit throwing your money away on synthetic.

Either extend your oil change intervals or quit buying synthetic.

meh i run mobil and change it every 3500 myself

oil is cheap insurance

i use ams on the summer car religiously.. switched over to it last year, combined with ams oil filtre, and i change my oil about every 10-15,000 miles, this is with daily driving, and track days every weekend, and im not exactly very easy on the car on most daily commutes, and the oil holds up just great.

plus jesus christ.. ever since i switched over, the car idles so rediculously quiet, that sometimes coming off the highway and coming to a stop.. i cant even tell the motor's running.


expensive sh*t... but worth every penny IMHO

converting the x3 to amsoil soon aswell

i use an australian made synthetic oil Nulon in my x3
change at 5000-7000kays
even at 3000kays the oil smells and looks bad

partly hotter climate but majority of that is my driving style smile.gif

plus...like somebody said....oil = cheap insurance (costs me $60 AUD an oil change)

ive used amsoil in my last 3 cars and am currantly using in both my wifes 08 accent and my 07 elantra both are in thier 11000miles after the oil change,looked at the oil and it isnt even close to dark yet,plus the added benifit of 3 more miles to the gallon over mobil 1 that was in the cars when we bought them, dont forget that they are the only ones offering a real garruntee, valvolines is not unless u put in befor 75000m and register it, but u still have to change every 3000 with it,it looks like crap after 1000m, i know i used to work there.

The oil will last 25k... but what about the filters? smile.gif

I use Amsoil in everything I drive. I run the Amsoil 15w40 diesel oil in my Dodge cummins diesel, and use an Amsoil filter in it, and change it every 25k miles. I have done many oil analysis', and I COULD go longer on the oil if I wanted to, as it comes back as acceptable to continue use, but I change it anyway, since it's what Amsoil recommends.



I used Amsoil XL on my old accent, with 180k miles on it, and changed it every 10k miles or every 6 months, whichever came first, and everything worked out great with that car, until it met it's demise in a rock slide :(. In my new Elantra, I will be switching to Amsoil at the next oil change. I just bought this elantra 2 weeks ago, so I haven't changed the oil that's in it yet. I am a believer, but I'd never force it down anyone's throats. Run what you want, and I'll run what I'm happy with :)

EDIT: Just realized this was a pretty old thread, but thought I'd throw in my .02cents..

I use VR1 in the Built Tib! It is built fairly "LOOSE" so i have to run a thicker oil! But I beat the piss out of and I change the Oil in this car every 3 Months or 2k Miles as im boosted and beat this car, so there are many heating cycles and it breaks down oil alot faster being feed through a cooked up turbo!

Wow how many times can one thread be brought back from the dead!?



My take on extended drain AMSOil is this: you pay double for the oil and leave it in twice as long. 25000 miles is their rating for cars on a light service schedule, 15000 is what average drivers should use (and is closer to the other new extended service oils claims) AND they say it is limited to a ONE YEAR oil change interval. So if you drive 15k miles or fewer, it's still a 1 year OCI oil. Yes it is an astonishingly good oil. No I don't think I could stand to go 25k miles unless someone else with this engine did it first and showed their UOA results.



That said . . . this is the wrong website for starting a thread like this anyway

The alternative is to pay half price for high quality synthetic oils and good filters, and change it twice a year. Six of one, half a dozen of the other, no net gain . . . unless you see a fuel economy rise with the AMSOil, which some people do report.



YMMV :lol:
