COX FUEL ?????

Most of my fuel is 50/50. Sig Champion was my fuel choice for over 20 years. Sig used Klotz in a 50/50 blend 10% castor/ 10% klotz. I also run full Klotz synthetic and I do it in vintage engines despite the naysayers indicating it will ruin engines. I've never ruined a engine running full synthetic fuel which included the purposeful intention of trying to destroy a Cox engine. I use nothing but Klotz products and never tried any other manufacturer of oil. Most of the time when I mix my Cox fuel, I use KL-100 castor/synth blend of Klotz. When I run out of this, I mix Klotz Benol and full synthetic Techniplate.

This is where things can get problematic, Klotz had to putz around with their product names. Klotz in the past offered KL-100, KL-200. Now its a mixture of whatever names sounds pleasing. They have original Techniplate, Super Techniplate and a myriad of others. One was full synthetic, the other being 80% synthetic with a 20% mix of castor. You have to read the description. My reasoning for using Klotz products are due to the way they mix with alcohol. I've experienced problems in trying to up the oil content of pre-mixed fuels. I've seen the oil separate and also float on top like vinegar and oil salad dressing.

I no longer doctor any fuel for a one very main reason which I mentioned above. The other is that companies like Morgan fuels WILL NOT disclose how they mix nor will they offer true contents. I've gone back and forth with them over the years on e-mails and the same answer always is in the end that the ingredients and contents used are trade properties which they will not disclose. I buy my stunt fuel and I've been mixing all other blends for a few years. The most difficult to obtain is the nitro which is over $100 a gallon delivered to my door. My main supplier which I used is no longer selling small quantities of nitro which is a bit disturbing. They will sell 5 gallons vs 1 gallon. For most, this is out of reach due to cost and or necessity to use it all.

The last speed shop of my area closed in the fall of 2022. Just prior to it's closing, I was purchasing methanol for under $5 a gallon. Now that gallon is over $20. I inquired about purchasing nitro which they wouldn't sell me at the time. If I didn't have a vehicle for it to go immediately into, they were not by law allowed to offer me nitro as a raw product. I could buy nitro which was preblended with alcohol which is VP's 50-50. This product is still available and it's also a more economical approach to making fuel. 5 gallons is under $200. This will require a bit more math but certainly worth the effort. My son and I use approx 7-8 gallons of stunt fuel in one year. VP Powermaster fuel is what I normally purchased which was the situation up to last year. The price skyrocketed so high it was not practical. I used to pay $24 for a gallon which is now $54 which doesn't include shipping. I typically buy 6 gallon cases.
