The amount of Optimax oil used per gallon of fuel depends on several factors, including the engine type, usage patterns, and operating conditions. Optimax oil is specifically designed for OptiMax and Direct Fuel Injected (DFI) 2-cycle outboard engines, which are known for their power and fuel efficiency. Compared to other 2-stroke models, Optimax engines consume similar amounts of oil but offer significantly better fuel economy, resulting in a richer oil ratio. Usage patterns, such as idling versus high-speed operation, also impact oil consumption. Additionally, factors like RPM and MPH influence the overall operating costs. Understanding these variables is crucial when calculating the running costs of an Optimax engine and determining the optimal oil-to-fuel ratio for specific applications.
| Characteristics | Values |
|---|---|
| Ratio of gas to oil | 40-50:1 |
| Cost of oil | $78 for 2.5 gallons |
| Cost of fuel | $0.13 per gallon |
| Fuel consumption | 5.8-6.0 mpg at 3380-3410 rpm and 28-29 mph |
| Fuel consumption at higher rpm | 5.4-5.5 mpg at 3800-4200 rpm |
| Oil consumption | 2 gallons of oil for every 70 gallons of gas |

Optimax oil is cheaper per gallon in 55-gallon drums
The cost of Optimax oil is a key consideration for boat owners, with some reporting that their engines have a gas-to-oil ratio of around 40-50:1. This means that a 55-gallon drum of oil will last a long time and could be a cost-effective option.
For example, one boat owner reported that their local dealer charged $18.75 per gallon of Optimax oil, whereas a 55-gallon drum from Quicksilver was priced at $20.95 per gallon. While the drum appears more expensive at first glance, the difference in price is minimal, and the drum offers the convenience of not having to frequently purchase smaller quantities.
Another factor to consider is that the price of oil can vary depending on the brand and retailer. For instance, the price of a gallon of oil can range from $28 to $32.99, with some dealers offering a better deal for larger quantities. Additionally, certain retailers, such as Walmart, are known for offering competitive prices on oil.
Buying in bulk, such as a 55-gallon drum, can often result in a lower price per gallon. This is because the fixed costs of production, such as packaging and transportation, are spread across a larger volume of oil. Therefore, while the upfront cost of a 55-gallon drum may be higher, it can provide a long-term supply of oil at a discounted rate.
Overall, purchasing Optimax oil in 55-gallon drums can be a more economical choice for boat owners, especially when taking into account the engine's oil consumption rate and the potential for small savings per gallon compared to smaller quantities.

Opti oil consumption is similar to other 2-stroke models at the same RPM
OptiMax engines use variable rate oiling, meaning that the amount of oil used per hour will vary depending on the RPM. Therefore, it is challenging to calculate the exact amount of oil consumed per gallon of fuel. However, users have reported that OptiMax engines are more fuel-efficient than other 2-stroke models, resulting in lower overall fuel consumption.
When compared to other 2-stroke models at the same RPM, the OptiMax engine exhibits similar oil consumption rates. This observation indicates that the amount of oil used per gallon of fuel is comparable between OptiMax and other 2-stroke engines operating at the same RPM. It is worth noting that OptiMax engines provide approximately 35% better fuel economy than regular 2-stroke engines, which may result in a perception of higher oil ratios.
The oil consumption in a 2-stroke OptiMax 150 engine was compared to a '95 Johnson 115, where the OptiMax was found to be more fuel-efficient. Additionally, another user with a similar boat and a Yamaha 150 4-stroke engine reported comparable fuel efficiency between the two boats. These comparisons further support the claim that OptiMax oil consumption is in line with other 2-stroke models when considering the same RPM and engine specifications.
It is important to note that the actual oil consumption of an OptiMax engine will depend on various factors, including engine usage patterns and operating conditions. For example, idling for extended periods will result in lower oil consumption, while rapid acceleration and higher RPMs will lead to increased oil usage. Therefore, the oil consumption rate may vary even within the same model of engines.
In summary, OptiMax oil consumption is similar to other 2-stroke models when compared at the same RPM. However, due to the variable rate oiling and other factors influencing engine usage, the exact oil-to-fuel ratio may differ. OptiMax engines offer improved fuel efficiency compared to some other models, which can impact the perceived oil ratio. It is always recommended to follow the manufacturer's guidelines for oil and fuel ratios to ensure optimal performance and longevity of the engine.

Opti engines use the same amount of oil as regular 2-strokes
Opti-2 is a unique type of oil compared to regular "ratio mix" oils. It is not necessary to run it "rich", or above the recommended amount of mix per gallon. In fact, exceeding the recommended amount by even a small amount can negatively impact performance. For example, doubling the recommended rate could result in a clogged carburetor. The recommended rate for Opti-2 is approximately 100:1, but some users have reported better performance at lower ratios, such as 40:1 or 50:1.
Opti-2 has been reported to extend the lifespan of two-stroke engines. One user reported that their saws lasted longer when using Opti-2 at a ratio of 75:1 compared to other oils at the recommended ratio of 100:1. Another user reported that they had been using Opti-2 for many years without any engine failures, although they noted that performance issues can arise when using a ratio above 50:1.
The OptiMax engine is reported to use a similar amount of oil as other 2-stroke engines, despite achieving better fuel economy. This gives the appearance of running a much richer oil ratio. The oil consumption of a 2-stroke Optimax 150 engine is said to be similar to other 2-stroke models when compared at the same RPM for a specific period. However, it is important to note that the Optimax engine uses variable rate oiling, so actual oil consumption may vary depending on RPM.
The amount of oil used per hour by an outboard motor depends on the engine type and the RPM at which it is operated. For example, a DFI 250 engine burns fewer gallons of gas per hour than an EFI 250 engine, but they use the same amount of oil in that hour. Therefore, the DFI engine uses half as much fuel as the EFI engine to do the same amount of work.

Opti engines have better fuel economy than regular 2-strokes
Opti engines are known to have better fuel economy than regular 2-stroke engines. A 2-stroke engine is less fuel-efficient because its exhaust is designed to draw the mixture through the engine, allowing fresh fuel and air in and pushing burnt exhaust gas out. This process works well for generating extra power, but it is not economical as it requires more fuel.
The Opti engine, on the other hand, achieves the same result in a different way. It only injects oil and fuel when both the ports are closed, reducing the losses of the unburnt mixture. This is controlled by a computer, which adjusts the oil and fuel intake based on the operating conditions. As a result, the Opti engine consumes a similar amount of oil as a regular 2-stroke engine but with significantly improved fuel economy.
For example, a 1996 Honda 90 4-stroke engine has a tank average of 5 mpg, while a 2001 Mercury Optimax 150 HP 2-stroke engine can achieve 5.5 mpg. Additionally, the Optimax engine can propel the hull to 60 mph, compared to the Honda's 38 mph, and it planes out in about half the time.
The improved fuel economy of the Opti engine is further evident when compared to other 2-stroke models. The Mercury Optimax 150 has a fuel consumption of around 4+ miles per gallon, which is comparable to a Yamaha 150 4-stroke engine. This demonstrates the Opti engine's ability to achieve better fuel efficiency than regular 2-strokes, making it a more economical choice.
However, it is worth noting that the comparison between 2-stroke and 4-stroke engines is complex. While 2-stroke engines were once competitive, advancements in technology have made 4-stroke engines more efficient in many applications. The simplicity, power-to-weight ratio, and MTBF of 2-stroke engines still make them a preferred choice in certain situations, especially in the case of Opti engines, which offer improved fuel economy within the 2-stroke category.
