Any reason NOT to use Amsoil

Recommended Posts

In a 2-stroke engine (any: air or water cooled 2-stroke), no reason, even with a lot of hours. Only one potential trouble area - if it has heavy carbon build up (from using cheap, low-quality oils) it should be decarboned first. AMSOIL will clean existing carbon and if it is heavy it may break loose in chunks, hang in the exhaust port, burn a piston or scar the cylinder wall (this is rare but has happened).

And the price is not that high! Compared to low quality oils at walmart yes, but compared to quality oils like quicksilver or other manufacturer brand oils even at walmart AMSOIL 2-stroke is not that high. AMSOIL HP Injector

is only $23.60 Preferred Customer wholesale price per gallon.

For a high mileage car or truck 4-stroke engine there is a thread on this in the automotive forum now.

If your motor is new, use the specific oil recommended by the manufacturer and be sure you wait until after the break in period to switch over to any synthetic oil. The superior lubricity of the synthetic will hamper the seating on the rings and actually reduce the long term efficiency of the engine. Once the break in is complete make the switch.

There are several techniques used by different shops. In my opinion the best job is done by pulling the head so you can clean properly. Some will use some kind of a hard nut shell to blast with and do it through the spark plug holes without pulling the head. The trick is to not get any foreign material through the ports and down in the lower end.

Any takes a competent mechanic. I have retired from all mechanic work over 10 years ago and have not kept up with the latest techniques.

The best - find a mechanic you trust. If you don't have one, ask here in the forum, someone should know of several good ones in your area.

Many 4-stroke outboards now come with synthetics from the factory new. The requirement is FC-W certified which AMSOIL 4-stroke marine oils are. Which? Use the viscosity recommended by the manufacturer. The second number is always the most important. AMSOIL marine lubes are available in 10W-30 prod. code WCT and 10W-40 prod. code WCF.

The most common for outboards is 10W-30 and the most common for inboards is 10W-40.

    • Anyone still at it?   not sure that i will get Isaac out anymore, will still ask these last few days.   Good luck everyone.
    • Haha, sounds like you have a good head on your shoulders and great perspective, Borch.  Plus, I think it's good to be upset about missing!  It motivates a guy to take more selective shots and make better shots.  My shot selection was ok, but my execution was not good.  I made a good shot at a stationary target, but the target was walking.  D-U-M, dumb!!!  Such is life!  Next year Morgan and I will shoot turkeys (as long as I can still get her out there).  
    • From what I read the idiot did not tell anybody....was asked to play in the World's and declined saying his wrists hurt so they made him go in and found the torn tendons...what a duffus.
    • It reminds me if the first year I took my son turkey hunting.  He had several close calls but didn't get a bird.  He was upset.  I said, "Why are you upset?  We got to hunt together for several days and had several exciting encounters.  If you shot one the first day we would have missed all that fun together"  He thought about it for a while and he smiled.  The older I get, the less its about the kill.  Reframing what I thought success was has added to my hunts.  Now, if I could get less upset when I miss a bird I'd have it all figured out.  
    • Excellent.  Nicely done.
    • You got it, Borch!  I was disappointed with how the season ended, but you're definitely right!  I also learned a trick this year- cards!  Morgan really enjoyed playing cards with me in the blind.  It was a good way to pass the time and we enjoyed it quite a bit.  We had a great season together and enjoyed it a ton!     That last encounter we had was really something!  I'm convinced the worst thing birds can do to a bowhunter is to come in to the deeks is stand there and stare.  I'd rather they hung up and didn't come in or did pretty much anything but that.  It makes it virtually impossible to get a bow drawn!  The turkey was at about 5 yards, because I knew we I needed one close for Morgan.  However, at five yards and staring directly in the direction of the blind, she was smart to not try to draw.  That dang bird stood there for two full minutes and didn't move a muscle.  Morgan had a smile from ear to ear and at one point told me "I was so excited and my heart was pounding so hard I thought I might die!"     It would have been a slam dunk with her crossbow, but she wanted to get one with a vertical bow.  I'm proud of her for sticking with it and she said "I'm just fine with not shooting one, Dad."  I'm glad she's ok with that.  I wish I was more ok with it...  but, that's hunting!  
    • Sounds like he is going to bring "fire" to the team haha.  Hoping he can come up with something to do with all the aging players who aren't living up to their contracts.     Also heard that Coyle played the last 2 months with torn ligaments in his wrists.  Going in for surgery.  Kind of an eye opener really, Coyle with torn wrist ligaments is better than anything they could've moved up that is healthy?  Uh oh....
    • Hey, it's all good. Morgan and you spending time together in the outdoors and getting a close encounter is what it's all about.     Sometimes the birds win and we simply run out of time.
