What is the extra cost both in mileage and in coolant of keeping the air conditioner knob at 100 percent cold compared to 60-75 percent?

There is no noticeable loss in mileage, certainly none in coolant of using a/c at 60% capacity versu 100% capacity.

It depends on which car you have. Some just mix in hot air to make it warmer. Other's shut off the compressor after the internal temperature has reached a certain point. The second type can save you gas if you don't run the a/c at 100%.

Yes, if the coolant is still clean and has not been in the system for long. But if you are changing the coolant at the recommended mileage of your cars manual then it should not be reused.

The RM 250 is a motocross bike that has no odometer, therefore there is no way of keeping up with the mileage.

It obviously depends on the cars being compared but generally Diesel provides better gas mileage.

You don't have to replace it until it starts leaking coolant.

did it change for the better or worse? if it changed for the better it could of been bad.

A high mileage for the vehicle is anything over 200,000 miles. Many people are keeping their vehicles longer as long as they are running well for them.

Keeping a vehicles service history up to date and keeping a vehicles tire pressure correct, is key to getting good mileage from your vehicle. Improved driving attitude, slow acceleration and anticipating traffic conditions, to make less and unnecessary use of the brakes.

Ford trucks are usually worse than other makes when comparing gas mileage. Brands like Toyota and Mazda are better.

Good question. I'm trying to find the answer myself. Closest I find is in the owner's manual on page 199, where it says "Replace engine coolant" without any mileage or time numbers.

Could be, lack of maintenance, abuse, lack of oil, lack of coolant, high mileage, exceeding speeds in any gear (abuse)

Up for debate--Will lower fuel mileage, but if you take into consideration the increased wind resistance created by having windows open--probably a wash Up for debate--Will lower fuel mileage, but if you take into consideration the increased wind resistance created by having windows open--probably a washYou will use more gas when your air conditioner is running.

From 25 to 30 mpg. It all depends on how you drive it, city or hi-way driving, fast or slow. The bugs are really reliant on keeping the valves adjusted for better running and mileage.

Don't use air conditioner or heater, roll windows down, and don't put stuff on top of the car (like a car top carrier).

I've heard of price often being compared with passenger mileage to compute proper ticket price.

User Avatar

Well there's no 'one best' - there are many to choose from and all will give (on an average) similar mileage when compared over a time-span (of course the cars compared are assumed to be of the same class).

Since your model of car is older you should use orange dexcool. It protects against rust in higher mileage cars

Compared to cars, pickup trucks get bad gas mileage. However, if you can find a hybrid or especially fuel-efficient model of truck (for example, Ford trucks tend to be slightly more fuel efficient than Toyota trucks) you may be able to get good gas mileage.

Four wheelers because they average 30-50 mpg compared to a vehicles 17mpg.

No it will not double the tire life, but NOT rotating your tires can cut your tire life by more than half. The mileage expectancy of a tire is calculated taking into consideration proper tire rotation, keeping them inflated to the proper PSI, how you drive, and correct alignment.

That depends on their company, how much experience they have, what method they're paid by (percentage or mileage), and how well their company does at keeping the wheels turning.

The cost of gasoline is rising, and this means more and more people are on the lookout for ways to improve their vehicle's gas mileage. The easiest way to get better gas mileage is to simply keep the vehicle maintained. The air filter, engine, and tires all play a part in a vehicle's gas mileage. By regularly replacing the air filter, keeping the engine in tune, and ensuring the tires are always properly inflated, a vehicle's gas mileage can be improved. In addition to better gas mileage, these steps promote the vehicle's overall performance and longevity, saving car owners money.

Diesel will always give you better fuel mileage as diesel fuel itself contains more BTU (the measure of thermal energy) in a given quantity than compared to gas.So therefore a diesel engine can extract more mileage out of a gallon of diesel fuel as there is more energy to extract out of that gallon as compared to a gallon of gas.Considering this, this is why diesel fuel prices would have to rise considerably over gas before the two would be equal on a cost per mile basis.

Radiator fluid or coolant becomes corrosive over time and damages the cooling system. Manufacturers give recommendations for replacement, but they can be confusing. Because coolant depletion is a chemical reaction, time if far more important than mileage. With a five year or 100,000 mile recommendation, five years are the key. Testing the pH of coolant gives a pretty good idea. New coolant has reserve alkalinity and measures 8.5 or higher. When coolant reaches 7.0 the reserve alkalinity is depleted and damage may begin. This is a good time to replace.

Currently, I am getting about 11 MPG and that is no jack-rabbit starts and keeping at 55 MPH and no extra weight as in hauling.
