Who remembers Bell Ray racing oil? I used to mix a 12.8 OZ bottle to 5 gallons of gas, had that castor oil smell. I found a bottle at a garage sale a couple of years ago for $1, I ran it through my two cycle stuff at 32/1 also.
I run Lucas semi-synthetic at 32/1, I have two engines over 10 years old running on it. I had the head off of both this week and the bore on both show minimal wear. Maybe I'm just lucky but I doubt it, I break in all new engines at 24/1 for a couple of tanks then go to 32/1. I run mine hard too, I don't know how accurate the tach is but I turned 8200 rpm on the grubee 48.
I add some blendzall 455 to that ( the lucas semi 2 stroke air cooled oil), and I will run my engines full throttle red line, for quite the straight away distance, when racing friends. Never had a failure, even though she'll be screaming her guts out as I'm pounding on her. My buddies can't figure out why I can beat the tar out of my bikes and they last forever, and they try it and soon to need a new engine. lol. That extra castor in the mix really saves on cylinder wear if you are rough on the engines.
