Is marine diesel cheaper than gas?
Lower Fuel Costs While both marine gas oil (MGO) and marine diesel oil (MDO) constantly fluctuate in cost, on average, diesel cost less than gasoline.
Are v8s good on gas?
Whether you enjoy the power of a V-8 engine in your muscle car or need to haul heavy work gear in your truck, a V-8 is never going to be as good on gas as smaller engines, such as a four-cylinder. However, there are several ways to improve your gas mileage to help your vehicle become as fuel efficient as possible.
What is the most efficient motor?
Tests carried out on a 44 megawatt 6-pole synchronous ABB motor shortly before delivery showed an efficiency 0.25 percent greater than the 98.8 percent stipulated in the contract, resulting in the world record for electric motor efficiency.
Does a V8 get better gas mileage than a V6?
Better Gas Mileage Almost all V6 engines use less gas than the larger engine sizes. This means that you will typically see better gas mileage in your V6 Ram when compared to its V8 counterparts.
Are V8 engines fuel-efficient?
Large V-8 engines can speed up in a hurry, but when you run with the engine wide open, it blows through your gas quickly. According to Edmunds.com, this trick can increase your vehicle’s fuel efficiency by up to 35 percent.
Do diesel boats get better gas mileage?

How many miles per gallon does a diesel motorhome get?
Diesel engine RV’s are more fuel-efficient than gas RVs. The average gas RV gets circa 6-10 miles per gallon, while a diesel motorhome will be 8-14 mpg range. In this article, we’re going to look into your options to get the best Motorhome Gas Mileage… Want to learn all the ins and outs?
How do you calculate kilometers driven to calculate fuel consumption?
Calculate your actual kilometers. Ending Odometer Reading minus Starting Odometer Reading equals total kilometers. End – Start = Kilometers. Calculate your rate of fuel usage ( l/100km) 100 * liters used ÷ kilometers driven = liters per 100 kilometers = l/100km.
