AMSoil Experiences with Cars & Trucks

[snpower]

Guys,

It's time to do the gearbox fluid on my BX2360 and there are a lot of good indications that AMSoil would be an excellent choice.

I"m actually considering switching my truck and car to AMSoil as well and am interested on hearing from others that may be running this oil in their vehicles. I believe both would run a 5W-30 synthetic. Right now I am using Mobil 5W-30 synthetic in our BMW and straight 5W-30 in my truck. The car has 125K on it and the truck 50k. Both motors are in excellent condition.

Why the change? I've been fairly impressed with literature on AMSoil, and have had some great discussions with the local reps.

You have something that's working well, but you were impressed with literature on AMsoil? Who wrote that literature? And what kind of discussion would you expect from an AMsoil rep?:laughing:

I tried Amsoil hydraulic fluid in my B2710 a few years ago because of the recommendation of some of our members on TBN. I'm quite confident that it's no better, no worse than other brands that could be bought locally. If you can get it cheaper than what you've been using, and you're sure of a readily available supply, I'd say go for it. Otherwise . . . well, it's your money.

Ok, opinion noted and good points.

I bought Amsoil back in 93. Then it was purported to be a 10-15,000 mile oil meaning it would last that long. I also spoke with factory reps I believed the hype and left it in my truck. At the 9000 mile mark, I blew a valve from the excess heat build up caused by insufficient lubrication. I contacted Amsoil and they did not want to hear it saying other factors were the cause even though they had an engine warranty of some type at the time. I was no stranger to engines as I built high performance ones for an additional living. This was definitely a heat related problem. The short of it is: do not leave the synthetics in any longer than your regular dino oil no matter what they say. The oil may still be good but it has picked up too many contaminates by 10,000 miles even if you change the filter. This increases its friction coefficient and thus causing subsequent heat build up.

I've been using it in about everything for a few years and have good luck. I did a lot of reading before I started using it. A lot of the stuff I read was not from Amsoil, so it was more independant. This is what I got out of a lot of the reading. In certain applications, some oils may be better than others, but as a general rule, Amsoil makes pretty good stuff accross the board.

The reason I'm using it I'm only changing the oil in my vehicles once a year. This is no more than 10,000 miles on my vehicles. I was often going past the recomended 6 month interval anyway so it gives me a little peace of mind. I'm also using their grease for such things like the gearbox on the mower for my Kubota. I'm also using it in my small engines.

I'm not sure I agree 100% with what Arrow says. Whats the point of using syn. oil if you don't extend the changes? If in doubt, send in an oil sample. Amsoil's best oil says a 25,000 mile interval, I won't go that long, but I think 10,000 miles or a little more is in reason.

Dirty oil is dirty oil, There is NO getting away from that. I dump car oil at 7500miles using Mobil 1 synthtic 5w20. If lots of city driving do it at 5000 miles.

SN - I don't know what your BX gearbox uses, but one thing I like about the Amsoil gear oil is that you can get a 75W110.

If you have older stuff in use, the present day '110 grade (long story short) is about where the old 90 grade topped out (viscosity wise). This may not be a concern for some people, but it is what I wanted when I did the diff fluid in my old E350 - it matters to me for towing.

Stretching motor oil changes out comes down to mostly 2 things (assuming a good quality oil) - upgraded filtration and getting oil analysis done - extending OCI without both can get expensive.

The only recent valid complaint I know of personally re. Amsoil is with 2 stroke oil - BUT, this was a race application, and not relevant to street use.

I've used Amsoil in the past and found it to be good oil. Used it in an F150 withthe 4.2L V6, and was trying to find an oil with outstanding wear numbers and provided a bump in mileage, all using a 5w-30 grade oil. The only oil that gave me a noticable increase in mileage was Mobil 1, but wear was up slightly over other oils (Royal Purple, Castrol 0w-30[German], conventional oils: Penzoil, Valvoline and Motorcraft). The best wear numbers came from the Motorcraft oil. Amsoil had low wear numbers, but nothing special for mileage. All oil was tested at drain intervals of 5000 miles. I was pretty diligent over the four years to doucment to the OCI, driving conditions and temperature conditions, but sometimes they did not match, so my data is not perfect.

The Amsoil, Royal Purple an Mobil 1 all seemed to reduce the cold start piston slap noise. But this is mostly subjective and in this truck, weather dependant.

In my opinion its a great oil, but nothing exceptionally better than the top teir synthetics and only marginally better than top teir conventional oils.

If you are able to get Amsoil at a reasonable price in comparision to retail stores, I say have at it. If you have to pay a significant premium, than there are plenty of oils out there that will do just as well for your equipment.

BTW - Since modern oils have been getting so much better over the last 20 years or so, I have long since dropped this as an obscession. I service all of my equipment regularly with high quality products and pay attention to all wear items including fluids and greases. My current truck (a GMC) has 178K miles and is running beautifully. With this truck I have been using a combination of brands of fluids (mostly synthetics, but not always), usually whatever I can find at a good price and whatever I'm "feeling" that day. Clean, cool and reasonable fresh fluids are really the ticket.

Guys,

Both motors are in excellent condition.

The brief time that I used amsoil, i could not prove it was any better than Mobil1... So to me it would be an availability thing and as always Price? If you had used conventional oil for 125k, I would say procede with caution on going to synthetic engine oils..So far no-one has Proved that one brand is especially perfect for everyone, hence many brands and various weights?

It always seems like everyone complains about AMSOIL. Maybe its because they are a small (compared to the likes of Mobil) company located in Wisconsin or maybe its because they won't sell their products in discount stores, who knows. I happen to be a loyal AMSOIL customer and dealer for over 30 yrs. I really couldn't care less what oil people use.

People make all kinds of claims that can not be substantiated often because they are a fabrication or at best a misrepresentation of the true facts.

There are those who will always be solely concerned with how much something costs and never consider the value. Just because something is cheaper does not mean it has value. Oil is not just oil. There is a difference in high-performance oils and the oils that just meet the minimum industry requirements. Oils in the marketplace only have to meet minimum performance levels set by API. All major synthetic brands are not the same; you can expect formulations to differ from one to another.

I use Amsoil in my cars and trucks, plus the engines of my B2410 and 2- BX's. I use their gear oil in my snowblowers and mowers, as well as front axles.

The only exception is hydro oil. Based on previous experience with non-Bota hydro fluid, I only use SUDT in my hydro units.

I would also look at schaffers products,oil & grease.Good prooduct IMHO.I have been useing it for many years.coobie

I run Amsoil in all my vehicles. The Mrs and I cover lots of miles, in the gassers I change the filter and top off the oil every 7500 miles, change oil and filter every 15000 miles. For us that is over 4 filter and 2 oil changes a year, over 150K miles and no issues. In my diesel, it is oil and filter changes every 10-15K miles depending on what I am doing. I am at 250K miles on that car and still running strong.

 

[Diamondpilot]

Its a good oil but not noticeably better than any other quality synthetic oil like Castrol, Mobil 1, ect.

Personally for things like tractors, boats, ect I do not run synthetics. I have 75 or more gas and diesel engines I maintain and have found that it does not pay because I change low use items like this yearly or about 75 hours on average. I would change it no matter what at the one year mark just to have fresh fluids in them.

That defintely sounds like you are doing well with Amsoil..I wasn't downing it, I was not a dealer. It would not stay in my Ford taurus, 3.0 v-6 and other oil would. If I use any synthetic oil I feel like it is helping the operation. Our cars were built for dyno oil and synthetic gets better mileage on fuel and changes..I am not sure of warrantys when you stretch the changes, beyond MFR. specs? I do replace the oil filter in-between changes..

How many of those using Amsoil joined in their pyramid scheme and became dealers? That was one of the main things that turned me off to Amsoil.

I have used Amsoil extensively, and I would compare it to any of the higher quality synthetics... or vise-versa!
Synthetics don't break down or "go bad" with age (they don't evaporate their ingredients), they don't absorb moisture, and they maintain a more consistent viscosity through a broader temperature range!
Start a car at -15 or below with standard oil, then switch to synthetic and start the same car at the same temp or colder and you will see one obvious benefit! And again in a warmer environment it will not "thin" as much as organic oils loosing lubricating properties.
The ability to leave the oil in the car for a year is due to the chemical stability of the oil and increased detergents to keep things from varnishing... that said, regular oil filter changes are still recommended and required!
(drain oil to a CLEAN container... put in a new filter and return the used oil adding the required amount of new oil to top up)

I wouldn't hesitate to do this with any of the quality synthetics! Amsoil included!
In fact if I'm not mistaken Amsoil and Royal Purple warranty their products for a full years usage... probably with their own filters but that's still a bold move for a product... especially if it is not up to the task with a considerable safety margin!

MHO based on real world experience and extensive research prior to using synthetics in several pieces of equipment I have maintained both personally and professionally!

Yea and try to collect on that Warranty......:laughing:

As much as I have tried to ignore this last comment, I can't.

Making comments like this about how it is marketed has no bearing on the products performance. For your information Pyramid schemes are illegal in the USA and many other countries. Companies that operate like that do not last for 40 yrs and have companies like Wix, Donaldson, Mann Filters, Briggs & Stratton as corporate partners.

AMSOIL is a legitimate networks marketing company.

 

[Z71]

Very few oil companies, if any, offer their own warranty program. AMSOIL does because AMSOIL is confident in the quality and performance capabilities of its products.

December 8, 2011 - Announcement

Briggs & Stratton, the world’s largest manufacturer of small engines, approached AMSOIL for help. Their goal was to produce a synthetic racing oil for their highest performance and most expensive engines used in kart, junior drag, quarter midget and other racing applications. AMSOIL was specifically chosen because of our technical resources and quality reputation, and we delivered technology that exceeded expectations.

This new oil will be sold exclusively through Briggs & Stratton, and the company has announced its availability in early 2012 for the upcoming racing season. They have elected to boldly display an AMSOIL logo on the packaging to boost the credibility of the product.
