I was out of premix that I normally use, so I bought Valvoline 2-stroke oil since I didn't want to wait for my other oil to arrive. Since I have not used this oil before, I mixed it to spec which is 20:1 for my 85 ATC250R. I know that 2-stoke oil is much better than it used to be, but I didn't want to take any chances which is why I mixed at 20:1. It seems WAY too rich. If anybody has used this oil before, what is a safe more diluted ratio to use. Thanks.

 

20-1 is way too rich for just about any machine. Even on high compression,high performance Ktm race bikes we mixed 32 to 36-1. You can use tcw3 which just about every oil company has,off brand Wally World tcw3 or even the synthetic"smokeless" oils that just might smoke a little less. Just cut the mix down to a max of 36-1 and see how it does. If still rich and boggy,go to 40-1.

 

Thanks for the response. The trike still has the original decal that says 20:1. I have always used 2-cycle oil that is mixed 40 or 50 to 1. I have never used Valvoline, so I was not sure. And it was definitely way too rich.
