Two-Stroke Oil-Injection Systems: What Owners Should Identify
By Interstate Marine ·
Two-stroke lubrication should be identified correctly before requesting service. An engine with oil injection, an engine using premixed fuel, and a four-stroke engine do not have identical oil-maintenance arrangements.
Interstate Marine offers two-stroke oil reservoir, line, and injection-system inspection, along with injection-oil replenishment and delivery-system inspection. The engine documentation governs the oil and delivery arrangement, especially when equipment has been modified.

Describe the installed system
Supply the engine manufacturer and model and explain whether the boat has a separate oil reservoir. If you are uncertain, provide identification photographs instead of guessing. Previous owner modifications or a repower make the installed equipment especially important.
Interstate Marine's service scope includes two-stroke oil reservoir, lines, and injection-system inspection. Two-stroke injection oil replenishment and delivery-system inspection are also available.
Explain any concern
Mention warning messages, visible leakage, changes in consumption, or uncertain service history. Those observations are starting points for evaluation, not proof that a particular pump or sensor needs replacement.
The oil product and any mixing instructions must come from the installed engine's documentation. If the system has been modified, include that fact; a reservoir alone does not explain the complete delivery arrangement.
Keep different fluid services separate
A two-stroke oil-system inspection does not replace lower-unit gear oil service. The gearcase still has its own maintenance needs. Record each task separately so “oil service” does not become an ambiguous line in the boat's history.
Make the inquiry useful
Bring model and serial information, the oil product currently used if known, and a description of the concern. Interstate Marine can then discuss the listed inspection and maintenance appropriate to that system without assuming a four-stroke service package applies.
Identify the lubrication arrangement before adding oil
Mercury's lubricant information lists distinct two-stroke formulations. The engine documentation must determine the product and delivery requirements for your installation.
A separate tank is useful information, but it is not proof that every part of an oil-injection system remains original or functional. If a previous owner changed the arrangement, provide the modification records. Tell Interstate Marine whether the concern involves a warning, visible leakage, or uncertainty about replenishment. Keep injection-system inspection and lower-unit lubricant service as separate invoice entries. An owner who records only “oil added” may later be unable to tell which reservoir or system received it.
Frequently asked questions
Is two-stroke oil the same as lower-unit lubricant?
No. They are different products serving different parts of the engine/drive arrangement.
What if I do not know whether oil injection is installed?
Provide engine identification and clear photographs so the arrangement can be discussed accurately.
How can I discuss two-stroke oil-injection inspection with Interstate Marine?
