There is no fuel-oil ratio on the E-TECs because the engine computer (EMM) determines how much oil is needed hundreds of times per second depending on the engine rpm, load, acceleration, temps, and throttle opening.
If you are a throttle jockey, your motor will use more oil than a motor running at a steady cruising speed. If you troll or run slow speeds a lot, the outboard will consume very little oil.
In an average recreational usage you will see from about 60:1 to 90:1. The thing to remember is that the E-TEC only uses on average about 1/2 the gasoline than an older type motor so you are practically going twice the distance on much less oil than the old technology outboards did.

The factory recommends that a properly trained technician service your Johnson or Evinrude outboard motor. Should you elect to perform repairs yourself, use caution, common sense, and observe safety procedures in the vicinity of flammable liquids, around moving parts, near high-temperature components, and working with electrical or ignition systems.
The information offered here is only general in nature and should not be construed as complete factory approved procedures, techniques, or specifications. Always use the proper service manual for your motor, up-to-date service literature, the correct tools, and have an understanding of how to proceed with troubleshooting and repair methods. If you are unsure or uncomfortable with a procedure, a situation, or a technique, enlist the services of a factory trained technician.
