Trufuel 40:1 vs 50:1

The Trufuel 40:1 vs 50:1 debate has been going on for quite a while. The fuel comes in two different ratios, which are both very different in terms of price and energy per gallon.

The 40:1 ratio, on one hand, is considered a great option for those looking for a fuel that is both affordable and easy to find.

The 50:1 ratio, on the other hand, is more expensive, but it contains more energy per gallon. They’re all made out of similar products but differ in some way. So, let’s look at the various aspects of these 2 versions and see how well they stack up against each other.

Trufuel 40:1 vs 50:1: What is the Right Ratio?

The ratio of gas to oil in a 2-cycle engine is important to know and can be found in the operator’s manual or on the engine label. However, if you can’t find either of those, you can consider figuring it out based on the age of the equipment.

For example, most handheld equipment manufactured before 2003 requires a 32:1 ratio, while most handheld equipment made after 2002 uses a 40:1 or 50:1 ratio. Outboard motors usually require a 50:1 ratio.

The standard ratio for a 4-cycle engine is 40:1, meaning 3.2 ounces of oil per gallon of gasoline. In contrast, the standard ratio for a 2-cycle engine is 50:1, meaning 2.6 ounces of oil per gallon of gasoline.

The difference between 50 to 1 and 40 to 1 oil mix is not very significant- although the 50:1 ratio is generally considered the standard set by the market. Most engines are manufactured to operate using 50:1 ratio oil mix, but you can still find 40:1 ratio oil mixes available in some stores.
