Frequently Asked Questions
Bonhoeffer engines are developed, tested and certified with petroleum based motor oils as a lubricant. Synthetic oils may be used; however, any motor oil used in our engines must meet all oil requirements as stated in the owner Manual. In addition, recommended oil change intervals must be followed.
Please see your owner's manual for detailed instructions for your specific model.
Bonhoeffer engines are designed and certified to run on regular unleaded gasoline containing no more than 5% ethanol (E10). Gasoline is allowed, by regulation, to contain a variety of additives. The same regulation limits how much of some additives, such as alcohol, can be included in the fuel and still allow it to be sold as gasoline. If you look in a Bonhoeffer product owner’s manual, you will see that a maximum of 5% ethanol is allowed (other oxygenates are also listed). Bonhoeffer engines are designed for good performance and efficient operation using gasoline containing from 0 to 5% ethanol. Always refer to the owner’s manual for your Bonhoeffer to get a list of recommended fuel and the current approved additives. For more information, see our Fuel Recommendations page.
