What is the proper fuel to oil mixtire?

This is a controversial topic. Depending on who you ask, you will get several different answers.

HPI recommends a fuel to oil ratio of:

  • 25:1 (25 units of fuel to 1 unit of oil.)

This is a great place to start. Using the HPI oil that comes with your Baja mixed at 25:1 will keep you safe. It’s recommended that you use this for the first gallon of fuel during the engine break-in process.

After the first gallon, if you’re confident in your tuning skills you should be fine by leaning out your oil and running 32:1. If you decide to use synthetic oil after the break-in period, 32:1 seems to be a good mixture.
