I've been using Chevron fuel for decades .
In the last 5 years or so, their fuel cost just wasn't worth it to me .
I started adding 1 fluid ounce, 29cc of Chevron Techron to every US gallon of fuel, 3.82 l .
I just removed the right throttle body on the oilhead for a rebuild .
The fuel injector looked new, no deposits on it .
Downstream of the injector there was a build up of deposits .
They came off easily with carb cleaner .
The oilhead has 83,000 miles, 136,000 km .
