Ahhh, the age old argument about what kind and how much 2 stroke oil should you put in your gas.
Let me start with this statement: I believe we should ALL put 2 stroke oil in our gas! I LOVE 2 strokes and even in 4 strokes it makes them smell wonderful!!
Ok, seriously! Let me start with "What kind?"
I truly believe that any of the synthetic MOTORCYCLE 2 stroke oils are good. I have used: Yamalube, Motul, BelRay, Redline and Motorex in the last 12 years and have never had a failure because of oil. I would not EVER use oil that the oil manufacturer doesn't recommend for motorcycles.
Now the heated debate about what ratio. I am going to keep this short.
I believe in using 40:1 to 60:1PERIOD!
Here is the relatively short reason I DO NOT believe in using less oil.
First, less oil equals less lubrication for the main bearings, connecting rod bearings and piston to cylinder. We all know that Lubrication is key! In all of life!
Second and possibly the most persuasive argument for more oil is HORSEPOWER! That's right! For an internal combustion motor to create the beloved horsepower we all love, the rings must make a seal with the cylinder walls. This seal allows the piston to "squish" the air/fuel mixture into the head so that it can ignite, go bang and generate force! The less oil, the less seal and therefore the LESS horsepower and torque! Yamaha did a test years ago using a dynomometer (not seat of the pants) to show that horsepower went up as the amount of oil went up until it hit about 30:1. Now I do like a clean pipe and swing arm so I run a little less oil than that (50:1 to 60:1 is my preferred mixture) but running 80:1 or 100:1 is silly and proven to create less horsepower.
There ya have it. Highland Cycles official stance on 2 stroke oil!
