I would run either all the castor and then straight switch to redline. It shouldn’t take to long to empty a kart tank. You could mix the two together. Just not recommended.

I’ve run Yamahas for many years. I’ve used castor, synthetic and combinations of the two. I ran the last 8 or 9 years on redline. It’s a good oil. Everybody has their opinion. As for whats in your tank, run it down low and then pour the new redline mix in on top. It will be fine.

I also agree with either premix will be fine

But please check with your club rules, as the previous owner may have not had a choice, since some spec classes will only let you use castor by Burris

I do like Red Line and Motul, but can’t use it at my club.

I honestly believe that any of those synthetic premix lubricants will help to prolong the life of the motor.

 

But if rules are not the issue here, I would highly recommend Motul or Red Line

Not to mention, it gets very cold where you live, and Castor will separate easier and faster

<p>Another vote for Motul 2 stroke oil. Please do NOT leave the fuel/oil mix in the tank on your kart. Only mix as much as you need for the day and drain it after the race weekend. Keep in proper gas can and shake it up good, before pouring it back in the tank for the next race day. Synthetic oils stay suspended in fuel a lot longer than castor oils do, but if you leave it in the tank for weeks, chances are, some of the oil will drop to the bottom resulting in poor running of the engine, you get the picture.</p>

Thank you all for the replies.  I’m checking with the club to see if they have any rules on what fuel mixture is required.  A quick scan of the rules on the website doesn’t make any mention but i want to be sure.

We are down well below a 1/4 tank sounds like I should be fine just filling it up with the new mix this weekend.  never though about letting it sit in the tank so that is good to know as well.

I’m sure I’ll be back with more questions.

Red Line is a great choice. I’ve been using it for years and have never stuck an engine. 16:1 is the right ratio for your set up. I would dump the remaining fuel just to inspect the bottom of the tank plus you want to get your needle settings with a know mix.
