I have been using Techron for decades as part of every 2 year smog test
preparation. I use 1/2 bottle to 1/4 tank gas. Drive hard for 60 miles,
change oil, ready for smog test.

Of course I also change the plugs, cap, rotor and make sure the O2
sensor voltage is cycling properly. No chance of passing Cali tests
without a working O2.

For many years when my wife and I both drove BMW cars the BMW dealers
sold Techron from stacks right at the parts and service counters. For
certain BMW models it was touted as essential for reducing deposits on
the valves of the engine unless you always ran Chevron Premium fuel.
