Well guys ive been using this stuff for a while and man its awesome...I changed the oil today after three tanks of gas and all I can say is wow...No shavings and the oil looked like it only had one ride on it...I use to run amsoil but could get the silkolene alot easier so I switched and man this stuff is tha bomb...The quad runs smoother and a lil bit cooler to me....It must be the ester....From what I understand Ester is extremely expensive but suppose to be the best out when it comes to synthetics....If anyone is in the market or on the fence for some great oil give this stuff a try...It wont let you down....There are other good oils out there but this stuff waxes the competition...Ive owned dirtbikes and streetbikes and this stuff is the best ive ever used.....

yep i use this stuff to i go onger on my oil changes withit and its still bright red

Yes sir this stuff comes out lookin like it went in....You dont get no better then that...Plus you can tell the motor runs better and stronger with it....Atleast I did when I switched from Amsoil to Silkolene...The ester is what makes it soooooo gooooood......Stuff doesnt break down at all....

Let me guess... You are a Silkolene dealer?

No, I'm not a dealer its just that good...When you find an oil that works its nice to let others know so maybe they can give it a try....It really is good stuff....Im not sayin its the best oil of all time....Just that it is one of the top performing oils....It comes out looking like it went in and that says alot...Not many others can say that.....

I use the stuff and echo the comments above...doesn't break down nearly as fast as other synthetics I've used.
