Amsoil

[Guest Friz]

I hear a lot about Amsoil Products, but I can find very little info. What makes Amsoil special?

[rocksolid]

I had one on my V6 tacoma. I liked it much better than the k/n filter. Here is a site that has some info on the amsoil filter,unfortunatly it is a toyota site,but it is still a good site for info.     www.Gadgetonline.com

I don't know but it works.  Everybody I know runs it in there mod sleds and the motors last twice as long as when they run regular polaris or RotaX Oil. My sled isn't a mod but I run it anyway.  It is expensive but then again they have 10k plus invested in those things plus the 30k+ youv'e got into a new truck.

I run it in my engine and I am going to cahnge over to their gear oil when the weather gets a little more stable.

They make a good product.

My father has been running amsoil for years Amsoil! I run it in my motor on my Z71 and it is good because the drain intervals are a lot longer than regular motor oil. My father should never have to change his oil again in his 97 power stroke, because he has a daul filter setup. all he does is change his filters and adds to it. He has over 20,000 miles on this oil and it tested good when he took a sample on it and sent it off to an independent lab that has nothing to do with amsoil.

I had a guy I use to dirt bike with that ran Amsoil in his Yamaha YZ250 at 100:1 ratio. Factory specs were 32:1. He never blew his engine so it must work.

Check out   www.performanceoiltechnology.com      or  www.thebestoil.com  for all the info you need.   Very interesting, very informative.  

 

My 98' gmc sierra with the 350 vortec uses about 1 quart of oil every 1000 miles (most of which seems to be leaking somehow into two of the cylinders judging by the plugs).  I decided to put some amsoil in it.  Did the engine flush and used 10w-40 to help with the leaking.  Well,  seems to be pretty good so far.  It seems to be getting slightly better gas mileage,  has a little more horsepower, and the oil usage seems to be tapering off (only have put on 400 miles since change so its tough to tell).  But the signs so far are good especially since when you first change the oil it is actually supposed to use more than it previously used until it eventually forms better seals on the rings etc.  Excited to find out how well this oil performs for me.  Heard a lot of very very good stuff about it from freinds.

 

I'll through an update on this post when I get a few more miles on the truck and have a better feel of how well it is perfoming.

Friz,

 

Amsoil was the first to have an API certified synthetic oil back in 1972. They have 30 years of research behind them.  Their additive package in their oils is really good. That is the reason you can go extended drains if you want to.

 

If you have any questions just let me know.

Tried Amsoil 5w30 in December, and have put about 8,000 miles on this change so far.  Getting ready for a filter change soon.  I'm really satisfied with what I have seen so far.  Before the change, my avg. mpg was about 18.  Since the weather has been warming here, I'm getting over twenty with alot of stop and go!  Definitely more horsepower, and saving me both time and money.  I would highly recommend it guys.  Just my two.

Here is food for thought.

 

During the week my truck is used by the wife. She drives 4 miles one way. Shuts it off and it sits for 8hrs. Sometimes she warms it up, but when I am not around I am sure she fires and goes.

 

I put Amsoil in the truck as part of a salesman pitch. At 300o miles I sent in a sample.  It came back OK except moisture was somewhat high. Was told to sample again.

 

At 6000 miles it was very high, oil was useless.

 

I did research and it is condensation building up due to lack of the motor getting fully warmed up then being shut down.

 

I do think it is a good oil, just costs so much for me to use and change it like I need to. It is just not practical to say everybody can run it at extended drains.

maggot,

 

I agree, it isn't for everyone. The benefits of the oil can protect your engine better than a conventional oil but there is a point that the oil stops and the extended drains are not the way to go. In your case regular oil with 3k oil changes are more practical.

 

Now the oil bypass filter would work well because it filters out moisture as well but then it can only hold so much just like any other. So depending on the driving habits that wouldn't be practical either.

 

Driving styles determine a lot on what oil to run. In your case regular oil. If you drove high mileage a year then synthetics work well but then not everyone feels comfortable with extended drains either.

 

It all boils down to what makes you comfortable. Just stick to good sound preventative maintenance practices and all should be fine.  "Ounce of prevention is worth a pound of cure". :thumb:
