I just changed my oil today, and I used amsoil for the first time . Anyone have any pros or cons?

 

cons: cost,availability
pros: longer oil change intervals, reduces wear

 

how much did you pay for it. i buy it for $36.00 a case

I use it in my truck and quad - both were switched from Mobil 1. I've also started using it in my chainsaw and lawnmower. I'll never go back to the previous.

 

I tested the Marine Diesel 15w-40 from Amsoil...for 10,000 miles on one oil change and one filter. Oil analysis was excellent, with lots of life left in it. I personally don't care for the super long term oil change intervals that some do with amsoil...but it can get cost effective if you drive your CTD a lot and change every 15,000 mi. or so.
Quality wise, I consider Amsoil one of the best oils on the market.

Tests have shown that Amsoil IS the best oil in the world. Me and me dad changed his Cummins M11 to amsoil and intantly noticed it was much smoother. It also takes much longer for the fan to come one when pulling a grade. We came back from Klamath falls to Vancouver washington and the fan never had to come on but we were only weighing about 45,000 lbs. We got the oil from my dads friend who buys it for his fleet by the 55 gallon drum. Much cheaper per gallon than buying it one gallon at a time.

 

check out these test results!! when I changed my whole truck over to Amsoil I saw 3 MPG better and that cant be beat for the price of diesel now-day'shttp://www.amsoil.com/lit/g554.pdf http://www.amsoil.com/lit/g1351.pdf http://www.amsoil.com/lit/g1343.pdf http://www.amsoil.com/performancetes...vs_mobil1.aspx

I wont use any thing else, it saves you money if you extend the intervals and makes it cheaper then regular oil

 

You don't need Amsoil to do extended drain intervals. Mobil-1 truck and suv or even Valvoline Premium Blue dino oil which is Cummins recipe will show good UOA results. Unless a particular oil is causing a problem, using more expensive oil won't yield any benefit. Valvoline Premium Blue meets Cummins' API ceritification requirements as well as Cummins' specific requirements. Read here about extended drain intervals for the ISX. Just my humble opinion based on word from those who build 'em.

you will not see the same MPG's that you would with Amsoil

 

Like I said, I once used Mobil 1 after break in and then I switched to Amsoil. There was a world of difference in a smoother idle, lower temps, and fuel mileage. I'll never go back. And, I still change my oil every 5000 km or 6 months, whichever comes first (drive company truck alot). It costs me roughly $40.00 for oil and a flter every change - do it myself. I'm running Amsoil 15w40 diesel and marine in my 360 gasser. This stuff at -40 Celcius pours freely whereas Mobil 1 10w30 synthetic looks like molasses coming out of the bottle - yes I actually did a pour test at that temperature.

 

You don't even need synthetic oil to do 15k "extended" changes. We have oil analysis equipment at work and have done 1k tests of Delo 400 up to 15k, still good to go. Adding a quart of makeup oil with 5k filter changes Delo was still good at 30k, when soot levels started getting too high. Adding a bypass filter system I believe Delo could go 50k.

Amsoil is good oil but the costs just don't pencil out. As far as longer engine lives, all of the million mile CTDs I've seen have been run on Delo or Rotella.

I use the 15/40 and have installed the bypass filter setup on my 2004.5

Have been using Amsoil since around 10,000 miles. Presently have 21,000 and enjoying the truck. I have used Amsoil for many years in many vehicles. It has never done me wrong in any of my vehicles. This is my first diesel with less than a year on it for time.

Well, I've used amsoil and it sure as hell didn't give me any better MPG. If you want to overspend for oil, go ahead, it's your money. Even though it's a full synthetic, it's still subject to contamination from the by-products of combustion. It's virtures are exteme temperature performance, so if you're in northern climates in winter, it may be a good idea.

Keep in mind this is a "boutique" blender using the multi-level marketing scheme. So you'll find their wholesale pricing is what most comparable products sell for at full retail. You have to pay shipping when buying wholesale, oil is no featherweight, and with the "preferred" customer charge, any savings is negligible. Plus, you'll find most of their products say that they meet API certification, but are not actually certified.

You cannot say their basestock is better than Mobil 1's, they're Mobil 1's number one customer for PAO basestock! The extended drain interval is marketing hype. If you browse used oil analysis reports on amsoil products, you'll find they thicken out of grade severely when run on long intervals in many engines. You'd be a fool to blindly run your oil for 25,000 miles without doing an analysis, and that costs money.

And of course, all the testing data is in their favor. You'll find the NOACK volatility test of the AME 15W40 does not compare it to another boutique synthetic manufacturer Redline, because Redline's 15W40 has a lower evaporation rate than does the amsoil. What does the four ball wear scar test mean? It's actually a test for grease, not motor oil. Dish soap or chlorine bleach would probably fare just as well when this test is used for motor oil.

If you're looking for a boutique oil, why not try Schaeffer's? Their products are quality, will cost less per mile, and wholesale pricing includes shipping to your door with no club fee.

Everyone has an opinion, and believe me, I don't have any monetary gain, but this opinion has been there, done that.

 

I would like to see proof of this.

 

Congratulations. But you are the exception to the rule. I did not see mileage increase and know no one who has?
I have tested several different oils in my CTD, synthetic & petroleum based oils...and never seen any difference in fuel mileage.
